The AXIS 2420 Network Camera (lens only supplied with AXIS 2420 W/Lens).

Connecting directly to Ethernet or Fast Ethernet networks, the AXIS 2420 is a standalone digital network camera that will also connect to a local Internet Service Provider using an external modem.

To simplify the installation process, the Web-based interface provides an Installation Wizard and an Application Wizard, which help you towards a seamless and automated integration into your networking and application environments.

Including a video output via a standard BNC connector, the AXIS 2420 also connects directly to any analog CCTV system to provide instant Plug-and-Watch integration into two parallel imaging networks - traditional analog, and modern digital.

Suitable for use in outdoor enclosures, the AXIS 2420 includes in-picture motion detection, making it the ideal professional surveillance tool.

Features and Benefits

Ease of Use - The AXIS 2420 is completely independent of any other server and requires no special hardware or viewing software. All you need to view live pictures over your network is Netscape Navigator 4.x or Microsoft Internet Explorer 4.x/5.x (used with the Axis ActiveX component or Java Applet). Whatever your choice of browser, the AXIS 2420 supports complete Plug-and-Watch functionality; so, all you need to do is assign a valid IP address.

Simple Administration - Using a standard browser, the AXIS 2420 is configured and managed directly from its own Web pages.

Cost-effective - The AXIS 2420 provides a reliable and low-cost resource for high-quality imaging over the network without the hidden accessories normally required by other digital cameras; such as, expensive software, management workstations, dedicated applications, video cabling or PC frame-grabber cards. Use the AXIS 2420 as a night watchman and exploit the downtime on corporate networks. With the AXIS 2420 there's no need to install coaxial cabling - just use your existing Ethernet networks for remote surveillance imaging - as well as for data communication.

Built-in Support for the AXIS 2191 Audio Module - The AXIS 2420 can be used directly with this add-on component, which enables live audio on your camera. The AXIS 2191 is supplied separately.

Open Standards Environment - Supporting TCP/IP networking, SMTP, HTTP and other Internet-related protocols, the AXIS 2420 can be used in mixed operating system environments; such as Windows, UNIX, Macintosh and OS/2. It integrates easily into other WWW/Intranet applications and CGI scripts.

Outdoor Use - The AXIS 2420 is a professional product including full DC-iris control and is shipped either without a lens (AXIS 2420) or with a DC-Iris varifocal lens (AXIS 2420 W/Lens). Both variants can alternatively be fitted with any standard C-CS type lens. Installed into an appropriate outdoor housing, the camera makes an ideal remote monitoring tool for outdoor use. Follow the accessories links for information on appropriate outdoor casings for the AXIS 2420 on our Website at www.axis.com.

Motion Detection - Sophisticated motion detection with in-picture alarm programming, and multi-window triggering for professional remote monitoring over TCP/IP networks, or via a modem.

Standard Image Format - In professional surveillance applications it's often critical for every recorded image to be of a high quality. That's why, in contrast to many inferior solutions that simply store image changes from one frame to another, the AXIS 2420 delivers up to 25/30 (PAL/NTSC) full, high-quality frames per second. Your pictures can be viewed using any standard browser and the data integrity of your recorded images is always assured.

Image Updating - The on-board AXIS ETRAX 100-LX processor combined with the revolutionary AXIS ARTPEC-1 Real Time Picture Encoder provides an amazing power-synergy to deliver up to 25/30 frames/second over 10Mbps or 100Mbps networks.

High Compression - The AXIS ARTPEC chip affords both an efficient and variable ratio of JPEG image compression that can be defined by the user.

Analog or Digital - The AXIS 2420 includes a standard BNC video output which means that apart from a connection over a modem or network, you can simultaneously connect the AXIS 2420 to any analog CCTV system. That gives you simultaneous video imaging over diverse surveillance systems.

External Device Connection - Supporting RS-232 and RS-485 communication protocols, the AXIS 2420 includes the physical interfaces for connecting a variety of external devices; such as, Pan/Tilt/Zoom devices, doorbells, switches and alarm relays. Develop your own PHP-based programing scripts for creating a variety of security applications triggered on time or alarm-based events. You can even drive annunciators and other audible alarm devices using the relay output.

Wide Range of Applications - The AXIS 2420 offers live video over internet networks and the Internet, and is ideal for use with many of today's high-speed internet services. Allowing remote access directly from your Web browser, you can view live images, manage, and control the AXIS 2420 at any time and from anywhere. The AXIS 2420's sophisticated features make it the ideal tool for intruder detection, industrial process control, public surveillance, visual security, and image archiving applications.

Modem Support - The Point to Point Protocol (PPP) support allows you to use your AXIS 2420 remotely over a serial link, just as if it were located on your local network. You can initially set up the AXIS 2420 over the network, or use a computer connected directly to the AXIS 2420 via the supplied Null Modem cable. The AXIS 2420 is accessed using a standard Dial-up (PPP) connection.

ISP Support - Arrange for the image files to be uploaded to an Internet Service Provider (ISP) and provide the global Internet community with browser access to your live images. Select any of the supported ISPs from the embedded Web-based Wizards, or choose your own preferred ISP as an imaging repository for your images.

Security - The AXIS 2420 includes a self-contained Web server, which means that your digital images can be protected just like any other Internet host. Data protection is normally implemented by your Network Administrator using the unit security settings in combination with an organization's Internet firewall. The Administrator can subsequently restrict image access to specific individuals or groups, or alternatively allow global access.

Linux Operating System - The AXIS 2420 includes modified versions of the Boa Web server, and Linux operating system - both of which are freely distributed under the GNU General Public License, as published by the Free Software Foundation. This software provides a stable and reliable platform for open-source development of the product. In accordance with the GNU General Public License, Axis has published the kernel for this product at http://developer.axis.com/.

DHCP

DHCP (Dynamic Host Configuration Protocol) is a protocol that lets network administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network.

Important!

DHCP should only be enabled if you know which IP address the AXIS 2420 will get from the DHCP server, or if your version of DHCP can update a DNS server, which then allows you to access the AXIS 2420 by name. If DHCP is enabled and you cannot access the unit, you may have to reset it to the factory default settings (see page 30) and then perform the installation again (see page 12).

System Security

To prevent unauthorized use of the camera, the AXIS 2420 supports multi-user password protection, and access can be restricted to defined users only. A system Administrator has unrestricted access to the product's Administration Tools and can determine the registration and access rights for all users.

Notes:

• When accessing the Administrator Tools for the first time you will be assumed to be the administrator and will be logged in as such, with the user name root and default password pass.
• The root password must however, be changed as soon as possible. Until this has been done, the security features in the product be will not be enabled. Furthermore, all Axis products are shipped with the same password by default.

User Access Rights

As an Administrator, click System and then Users to perform any of the following tasks:

• define or edit the administrator (root) password
• define, add and delete user names and passwords
- assign individual access rights to a selected user, where each user is awarded with one or more of the following levels of access:

• Admin: a user granted with Admin rights has unrestricted access to the Administration Tools and can consequently determine the registration of all users.
• Dial-in: provides the user with dial-in modem access only.
• View: provides the lowest level of access, which only allows the user to view images.

Important!

By default, the AXIS 2420 supports anonymous user access, which means that anybody on the Internet/intranet has access to the images (but not the Admin tools) from a browser.

To restrict open viewing access, simply register a single authorized user. This effectively revokes the anonymous user service and restricts access to specified users. If the anonymous user service is satisfactory for your application, simply do not add any users. The Administrator's own settings are enough to provide anonymous viewing access.

Motion Detection

The AXIS 2420 includes in-picture motion detection, for creating specific surveillance zones in the image area. You can create, name, and use up to 3 motion detection windows. You can also move, resize, or delete them at any time.

Use motion detection to generate an alarm whenever movement occurs in the specified area. Simply click and drag with your mouse in the image area to create and automatically enable a motion detection window. Movement outside the window area is ignored.

Creating a Motion Detection Window

Follow the instructions below to create a motion detection window in your surveillance area:

1. Click the New button to create a new motion detection window or simply click in the image.
2. Drag the bottom right corner of the highlighted rectangle to cover the area you wish to monitor. Release the button. To move the window, click and drag the title bar to the desired location.

3. Enter a unique name for your window in the Name field.

4. Set the Size, History and Sensitivity profile sliders accordingly for the surveillance area. The sliders are described briefly below. A fuller description is provided in the on-line help.

5. Size - The relative size of the moving object in the motion detection window.

6. History - Specifies for how long a moving object will trigger the motion detection before being regarded as non-moving.

7. Sensitivity – The higher the level, the less contrast is needed to trigger the motion detection.

8. If you are using Netscape Navigator, click Save to save your motion detection windows. In Internet Explorer the windows are saved automatically.

9. Having created a new motion detection window, you are now ready to test it. Create some physical disturbance within the motion window area and check the motion indicator box. If the window does not react as you want it to, adjust the sensitivity slider. The horizontal line will move to reflect the new setting. When the motion indicator shows activity in the image, it is the activity above the horizontal line which will trigger any alarms you may have set.

Note: Motion detection windows support simple drag-and-drop functionality, which allows you extend or reduce the window area at any time. To delete a window, select the window and press Delete.

COM-Ports, Modems and Pan-Tilt-Zoom Devices

The supported COM-ports are one RS-232 and one RS-485/422 port. The RS-232 port is connected via the 9-pin D-sub connector on the rear of the unit and the RS-485/422 interface is via the I/O-B terminal block connector.

The RS-485/422 port supports the connection of an external device, usually a Pan Tilt unit. The RS-232 port can be used for the same purpose, but also for connecting a modem or the AXIS 2191 Audio Module. For details on how to connect and configure the AXIS 2191, please see The AXIS 2191 Audio Module, on page 38.

Note: Only one port at a time can be used for controlling a Pan Tilt device.

Setting the RS-232 Port for use with a Modem

From the External Devices link on the Administration page, select the RS-232 port and click the radio button for Modem. Some basic modem settings can now be made directly from this page. Click Save. To further configure the modem, click Modem (also from the main Administration page) and then General or ISP.

Modem

The Modem page allows you to set your specific modem type and configure it, using the following parameters:

• Disable incoming calls - use this only if you will not need to dial-in to the AXIS 2420.
• Modem Type - set the brand of modem and provide a specific Initstring, if required.
• Communication Settings - advanced settings for your modem. Please see the documentation for your modem.
• Callback - use this to get your modem to return your call. The number of ring signals to wait before callback and the number of seconds to wait before disconnecting can both be set.

ISP

This page provides the fields for entering the information specific to your own ISP. If your own ISP is not listed, use the Generic setting. The settings available are; the number you dial to your ISP, your user name and password, the connection type and the re-dialing properties. You can save on phone bills by setting the connection type to Closes After or Optimized. See the on-line help for more information.

Using Pan-Tilt-Zoom Devices

There is a wide range of Pan-Tilt-Zoom (PTZ) devices available on the market today. Some of these can be used with your AXIS 2420 to provide a simple means of remotely aiming and controlling your camera. A PTZ device connects directly to the AXIS 2420 via the RS-232 port or RS-485/422 port on the back panel of the camera. Both ports support the use of these devices, but only one port at a time can be used for the purpose.

Apart from the COM settings shown by default for the COM ports, selecting External Device for the port will also reveal a section called Pan Tilt Settings. The drop-down list allows you to select the driver for your PTZ device. The devices in the list are the ones currently supported by the AXIS 2420. For the latest information concerning supported PTZ drivers, please see the Axis Web at www.axis.com.

Connecting PTZ Devices

The diagram below illustrates how the AXIS 2420 connects to your workstation and PTZ device.

Installation Procedure

Follow the instructions below to install a PTZ device:

1. Attach the PTZ device to the RS-232 or RS-485/422 port of the AXIS 2420 using the appropriate cable.
2. On the AXIS 2420 Home Page, click Administration Tools.
3. Click on External devices and then select the port you wish to use for your device. Click Save.
4. Now click on the PTZ link. Select the driver that corresponds to your PTZ device from the drop-down menu.
5. You can now change the default settings and preset positions (see page 29) by clicking the buttons provided and by selecting values from the drop-down lists. After making your settings, click Save. If your Pan Tilt device also supports the Zoom function, refer to the devices's documentation for details on how to connect a zoom lens.

When using a Pan-Tilt device, the camera's home page will show Pan and Tilt bars, as well as a drop-down list for preset positions, if this is supported. Note that the presence and appearance of some functions (e.g. the zoom function) will depend on the Pan-Tilt device being used.

Preset Positions

To enable quick and accurate camera positioning to known camera hotspots, the Administrator can set and save any camera orientation as a named entity - a Preset Position, which can be used at any time. The orientation for the camera is controlled by Pan and Tilt control bars.

Follow the instructions below to define a preset position:

1. From the COM-Port page, click the Preset Position button. An image from the camera (at its current position) is displayed in a new window.

1. By clicking in the image or by using the Pan Tilt and Zoom (if supported) control bars, move the camera to the desired position.
2. Enter a descriptive name in the Current Position field.

3. Click Save to register the new preset position with the AXIS 2420 and then check that the entered name is included in the Preset Positions drop-down list. You can alternatively choose to save the position as a new Home position, by clicking the Save as Home button.

4. Click Delete if you want to remove the selected preset position.

Established preset positions are selected from the Preset Positions drop-down list on the application viewing page.

The Factory Default Settings

In certain circumstances, it may be necessary to reinstate the Factory Default settings for your AXIS 2420. This is performed by clicking the appropriate button in the Administration Tools, or by pressing the Control Button (see the illustration on page 9). Follow the instructions below to reinstate the product factory default settings using the Control Button:

1. Switch off the AXIS 2420 by disconnecting the power cable.
2. Press and hold the Control Button pressed, and reconnect the power supply cable.
3. Continue to keep the Control Button pressed until the Status Indicator displays yellow (note that this may take up to 15 seconds), then release the Control Button. When the Status Indicator displays green (which can take up to 1 minute) the AXIS 2420 will then have been reset to the original factory default settings.

Note: Reinstating the factory default settings causes all parameters (including the IP address) to be reset.

Choosing Your Application

The AXIS 2420 can be used in a wide variety of applications and installs directly onto an Ethernet network, or over a V.90-compatible modem. Requiring no additional software on your viewing desktop, it is a completely self contained unit that delivers crisp live images to your browser. Using the Web-based Administration Tools and easy-to-use Wizards, you can quickly and easily develop your application.

This section contains a few examples of typical applications, and also includes other reference information to help you configure your product.

Networking Applications

If you have access to an Ethernet connection at your installation location, simply plug the AXIS 2420 into your LAN/WAN and set the IP address. You are then ready to view images from any desktop over your network.

However, the AXIS 2420 offers more than just convenient access to live images over the network. Using the available Wizards to guide you through the process, you can quickly and easily configure your product for a variety of exciting applications, including:

• Using Motion Detection to generate alarms and trigger uploads of recorded images.
• Connecting an external alarm device, e.g. a door switch, to the AXIS 2420 and uploading pre and/or post alarm images to a target FTP server when an alarm or time-based event occurs; and optionally, sending e-mail alerts containing images, and/or a link to the camera.
• Uploading images to a remote FTP server on a LAN/WAN network to accommodate a large viewing audience, where a high volume of Web page hits is anticipated.

Note:

You can access live images from a desktop browser on your network as soon as the AXIS 2420 is physically installed on your network. Both advanced and novice users should then use the Wizards to configure the chosen application. After the basic configuration has been established with the Wizards, advanced users can then use the Web-based Administration Tools for refining the application.

Picture frequency for Networking Applications

When used in a TCP/IP networking environment, the AXIS 2420 delivers up to 30/25 (NTSC/PAL) images/second. The perceived frame rate in your browser is typically limited by:

• the number of clients accessing the images
• your computer and browser
• the chosen image resolution and compression
• the lighting conditions at the point of installation
  • available network bandwidth
• the complexity of detail and color variation within the image

Note: The AXIS 2420 is available in NTSC and PAL variants to accommodate the different power supply frequencies in the USA and Europe.

Image Compression Ratios

Although the file size of a JPEG-compressed image depends upon the actual content of the image, images containing great detail generally generate larger files. Image quality is largely controlled through the level of compression; where high compression yields small files, and low compression maintains higher image quality at the expense of larger files. The table below is derived from real-life tests, and defines the average file sizes for each supported image resolution:

NTSC PAL
Resolution File size (kb) Max fps* Resolution File size (kb) Max fps*
4CIF (704 x 480)	7 - 150	10	4CIF (704 x 576)	8.5 - 180	8
CIF (352 x 240)	1.4 - 40	30	CIF (352 x 288)	1.7 - 50	25

* Maximum performance for a single viewing client.

Note: Using a modern computer will avoid introducing any unnecessary constraints on the image frequency.

Modem Applications

If a local network connection is not available at your chosen point of installation, you can alternatively connect your AXIS 2420 to a V.90-compatible modem and quickly configure any number of exciting applications using the Wizards; including:

• Using Motion Detection to generate alarms and trigger uploads of recorded images.
• Uploading single or pre/post alarm image sequences to your ISP over a modem connection, when an alarm or time-based event occurs; and optionally, sending e-mail alerts containing images or links to pre/post alarm images stored by your ISP.
• Sequentially uploading images to an ISP (Internet Service Provider) over a modem connection and publishing images to the whole Internet community.

Important!

• Although the AXIS 2420 is compatible with most V.90-compliant modems, Axis takes no responsibility for V.90 modems that fail to work with the product.
• When the AXIS 2420 is dialing out it will obviously not be possible to dial-in to it. If you configure an interval during which the camera will not be dialing out, this will allow you to dial-in and make any necessary changes, etc. If you also have an Ethernet network connection, then this will always be available, even if the camera is dialing out via the modem connection.

Configuration

All modem applications must initially be configured from a browser on a local computer. If available, you should always use an Ethernet network for this purpose, even if the actual application will be using a modem. When there is no network available, you can use the supplied Null Modem Cable to create a direct connection to the AXIS 2420 from the computer. This direct connection is only intended as an alternative for the initial configuration of the modem application in the absence of a network. The Null Modem Cable should not be used for any other purpose.

Note:

Once the modem connection has been created and the AXIS 2420 is physically connected to the modem, you can then connect to your camera in exactly the same way as you would to your ISP - with no further configuration whatsoever. You use the Installation and Application Wizards to establish the basic parameters for your application, and advanced users can optionally use the Administration Tools to refine their application once the basic configuration is complete.

Picture Frequency for Modem Applications

The speed of your modem link is a dominant factor in determining the frequency at which images are displayed in your browser, and an average-sized image is normally transmitted in 2-4 seconds. For alarm applications, where picture updating is critical, images are buffered into internal memory prior to being uploaded to your ISP or Web server. This means that a slow connection will not prevent your images being correctly saved and transmitted.

Proprietary ISP Dial-up Protocols

If you need to install any special software before initiating a dial-up connection, it is likely that your ISP is using proprietary protocols incompatible with the standard-based AXIS 2420. In these circumstances, we recommend that you ask your ISP for an alternative dial-up service that allows for standard dial-up networking. Axis does not guarantee the compatibility of this product with any ISPs requiring the use of proprietary or non-standard software as a pre-requisite for dial-up connections.

Sequentially Uploading Images to an FTP Server/ISP

Ideal for busy Web sites on large or small networks, this application uploads images to an FTP server/ISP, via the network or a modem, and is perfect for applications where a large audience is expected. Your images can then be accessible to several specific users, or to the whole Internet community! You can select any of the ISPs in the Application Wizard, or specify your own.

    A["FTP Server/ISP"] --> B["Intranet or Internet"]
    C["AXIS 2420"] -->|LAN/WAN/Modem| B
    D["Browser"] --> B
    E["Browser"] --> B

Simply install the AXIS 2420 directly on your local Ethernet network or via a modem, and then complete the Installation and Application Wizards to develop an active application that will upload images to a designated FTP server - as a sequential stream that is unlimited, or restricted to specified time periods. You organize the times and the frequency at which your images are taken and uploaded to the target server.

Installation and Configuration Overview

Configure the AXIS 2420 to actively upload images to an FTP server/ISP, as follows:

1. Connect the AXIS 2420 to your local network, or, if no network is available, use the null modem cable to create a direct connection to a local computer. Refer to Installing on a Network, on page 12, or Installing via a Modem, on page 14.

3. Continue the configuration using the Application Wizard, defining the target FTP server/ISP and setting Sequential as the mode of operation. You will also be able to make settings for the upload destination, times for recording images, etc.
4. If you used the null modem cable to configure a modem application, disconnect it and connect the camera to your modem.
5. Having completed the Wizard, you should now verify the configuration by accessing the images stored on the FTP sever/ISP from your browser. You can refine your application at any time, using the Web-based Administration Tools.

Uploading Pre and/or Post Alarm Images to an FTP server/ISP

The AXIS 2420 is the ideal solution for a wide variety of surveillance and process control applications. By connecting your external alarm devices to the I/O connector (see Appendix F - The Unit Connectors), you can quickly configure the product to upload single images, or send pre/post alarm image sequences to an FTP server or ISP when an event occurs. The images can be transmitted over an Ethernet network or via a modem connection.

Using the Wizards, you can organize the times and frequency at which images are taken and uploaded to the target FTP server/ISP. There are also options for sending e-mail alerts containing images and/or a link to the camera.

Installation and Configuration Overview

Configure the AXIS 2420 to upload Pre and/or Post Alarm images, as follows:

1. Connect the AXIS 2420 to your local network, or, if no network is available, use the null modem cable to create a direct connection to a local computer. Refer to Installing on a Network, on page 12, or Installing via a Modem, on page 14.
2. Open the Home Page in your browser and start the Installation Wizard. Complete the Wizard to establish the basic settings - selecting the connection method in the Modem or Network dialog. Refer to Configuring Your Camera, on page 18.
3. Continue the configuration using the Application Wizard, defining the target FTP server/ISP and setting Alarm as the mode of operation. You will also be able to make settings for the upload destination, alarm conditions, etc.
4. If you used the null modem cable to configure a modem application, disconnect it and connect the camera to your modem.
5. Having completed the Wizard, you should now verify the configuration by triggering an alarm and then, in your browser, viewing the images sent to the FTP sever/ISP. You can refine your application at any time, using the Web-based Administration Tools

Notes:

• Modem connections - except for when the AXIS 2420 is dialing-out, you can change the product's configuration at any time using the modem connection, or a local computer connected via the supplied null modem cable.
• If you also have an Ethernet network connection to the camera, then this can always be used to access the camera - even if it is dialing out via the modem connection.

Viewing live Images in a Browser

This application represents the most basic application using a network camera. It is ideally suited for occasionally-visited sites on both large corporate networks, and SOHO (Small-Office Home-Office) applications, where a small network is installed and maintained. If you anticipate a large audience for your images, you should consider configuring your product to upload images to an FTP server/ISP, as described in Sequentially Uploading Images to an FTP Server/ISP, on page 35.

Installing the Audio Module

Before installing the AXIS 2191 Audio Module, first install your network camera. Refer to the installation section of this manual. If you intend running the audio module in full-duplex mode, check that the sound card on your computer supports this.

Configuring the Audio Module

The network camera's administration pages provide all the tools required for successfully configuring the AXIS 2191. From the camera's home page, click on the link to Administration Tools. A new page containing the tools will open. To complete the configuration of your audio module, follow these instructions:

1. From the Admin tools, click External Devices. Select the AXIS 2191 Audio Module as the device to use. Click Save. Note: If you do not see External Devices, then your camera does not have the correct firmware installed and it must be upgraded. Please see Updating the Firmware, on page 63.
   2.Under External Devices, click Audio. This opens the configuration page for the audio module (see illustration below).
2. Select the audio mode. This can be:

• Full-Duplex (Talk and Listen Simultaneously)
• Half-Duplex (Talk and Listen)
- Simplex - Talk
- Simplex - Listen

This selection will depend on your application. See page 42 for more information.

1. Enter the number of clients that will be able to access the application at any one time. Use this setting to limit access if you only have limited bandwidth available.
2. If you are using Half-Duplex mode, the Send option can be used to send audio from the client currently transmitting to all the other clients, and not just to the server end. Set to Yes to enable the function.
3. When using Half-Duplex, the Push-To-Talk button will be visible. Select the mode to use for this button. Selecting Toggle means that when the button is pushed it will remain so until pushed again. Instant means that the button will remain active (pushed) until released.
4. Adjust the Volume Out control until a satisfactory speaker level is heard. The Level Out LED can be used to check that there is audio being received. Note that both the control and the LED are on the audio module itself.

The configuration page for the AXIS 2191.

Using the Audio Module with Your Camera

Your audio module is now configured and ready for use with your network camera. Enter your camera's IP-address in Internet Explorer, or click Home on the camera's admin page. You should then see the control panel for the AXIS 2191 below the camera image. If no audio controls are visible, check that you have made the correct setting under External Devices.

Using the Different Audio Modes

Full-Duplex

Full-Duplex mode means that you can transmit and receive audio (talk and listen) at the same time, without having to use any of the controls. This is just like having a telephone conversation. The only controls you may wish to use are the mute checkboxes to turn off the sound, and the level sliders, to adjust the input/output levels. This mode requires a full-duplex sound card on your computer. If your available bandwidth is 0.2Mbit/s or less, it is recommended that you use Half-Duplex mode instead.

Half-Duplex

Half-Duplex mode also sends and receives audio in both directions, but only in one direction at a time. This means you must actively transmit with the help of the Push-to-Talk button. To speak, press the button (check that the microphone is not muted). When finished speaking, release the button. You will now be receiving audio from the other end of the connection. Note that the Push-to-Talk button can be configured for use in two different ways - Toggle or Instant. This is set in the camera's admin tools. Half-Duplex mode is best if you only have limited bandwidth available.

Simplex - Talk

Simplex - Talk mode means that only the web-client end of the connection can transmit audio (that is, to the AXIS 2191). This could be used, for example, to provide spoken instructions to a person seen in the network camera. This mode also requires you to use the Push-to-Talk button.

Simplex - Listen

Simplex - Listen mode can only receive audio from the AXIS 2191 to the web-client. This can be used in remote monitoring, web attractions etc., to provide live audio, as well as video, of a monitored situation.

Appendix A - Troubleshooting

This appendix provides useful information to help you to resolve any difficulty you might have with your AXIS 2420. Symptoms, possible causes and remedial actions are provided in a quick reference table.

PINGing Your IP Address

By sending a packet to the specified address and waiting for a reply, the PING utility can determine whether a specific IP address is accessible. It also provides a particularly useful method for confirming addressing conflicts with your AXIS 2420 on the network.

Having disconnected your AXIS 2420, follow the instructions below in association with Symptoms, Possible Causes and Remedial Actions, on page 48, and run PING to troubleshoot TCP/IP problems on your network:

1. Start a Command window.
2. Type ping x.x.x.x, where x.x.x.x is the IP address of the AXIS 2420.
3. If you receive the reply destination host unreachable, then the AXIS 2420 is not accessible on your subnet. You must obtain a new IP address and reinstall the unit.
4. If this does not solve the problem, disconnect the AXIS 2420 from the network and run the PING command again. See the table below for an interpretation of the results.

PING Reply Interpretation and recommendation

Reply from: bytes = 32; time = 10 ms....	The IP address is already used and cannot be used again. You must obtain a new IP address.
Request timed out	This IP address is not used and is available for use with your AXIS 2420. If you set the IP address previously, the installation might not have been performed correctly. In this case, reinstall the unit. Also check all cabling.

Symptoms, Possible Causes and Remedial Actions

Symptoms Possible causes Remedial actions

The AXIS 2420 cannot be accessed from a Web browser.	The IP address is already being used by another device.	1. Disconnect your AXIS 2420 from the network.2. Run the PING utility (as described in PINGing Your IP Address, on page 47) and follow the appropriate recommendations.Note: The assigned IP number can be assumed as being available for use if PING returns "request timed out" - in which case you should set the IP address again, power on the AXIS 2420 and then try accessing the unit again.
	The IP address is located on a different subnet.	Run the PING utility (as described in PINGing Your IP Address, on page 47). If the utility returns no response or similar, then this diagnosis is probably correct.In Windows, check that the IP address for your AXIS 2420 is on the same subnet as your workstation. Exactly how this is done varies from one version of Windows to another. See Windows' help for more information.If your AXIS 2420 is on a different subnet than your workstation you will not be able to set the IP address from this workstation. Contact your network administrator.
	In Windows 95, the ARP table was empty when you tried to set the IP address.	In Windows 95, the ARP command cannot be used if you have an empty ARP table.Type arp -a to view the ARP table. If it is empty, you must ping an existing unit on your network before you can download the IP address to the AXIS 2420, using ARP.The AXIS IP Installer is a good alternative to ARP.
	The IP address has changed. Check that there is no DHCP or BOOTP server running on your network.
	Possible problem with your proxy server.	Try disabling the proxy default in your browser.
	Other networking problems. Try replacing your network cable.
		Test the network interface of the product by connecting a local computer to the unit, using a standard Crossover (hub-to-hub) Cable.If the above actions do not resolve the problem, the AXIS 2420 may be faulty. In this case, try to localize the problem by connecting the AXIS 2420 to the serial port of a local computer, using the supplied Null Modem Cable and report your findings to your local distributor.
The Power indicator is not constantly lit.	Faulty power supply. Verify that you are using an AXIS PS-D power supply.

Symptoms Possible causes Remedial actions

The Network indicator displays red.	Faulty cabling. 1. To verify that the cable is functional, connect the cable to a known functioning device on the network and PING it from your workstation.2. If the cabling is OK and your network is reachable, you should receive a reply similar to this:Reply from: bytes = 32; time = 10 ms....
The Active and Network indicators are flashing every 0.5 seconds.	Hardware failure. Contact your Axis dealer.
Your AXIS 2420 works locally, but not externally.	Firewall protection. Check the Internet firewall with your network administrator.
	Default routers required. Check if you need to configure the default router settings.
	The Internet site is too heavily loaded.	Configure the AXIS 2420 to upload your video images to an FTP server or an ISP.
No image using Refresh and/or Slow updating of images.	Multiple clients attempting to access the images, or complex images, i.e. containing a lot of contrast.	Try limiting the number of clients, or configure the AXIS 2420 to upload your video images to an FTP server or an ISP. Adjust the image settings to produce smaller files.
Cannot access the connected modem.	Faulty cabling. Check power supply, power cable and serial connection.
A series of broad vertical white lines appears across the image.	The CCD sensor becomes overloaded when the light is too bright. This can happen e.g. with sunlight reflections.	If you are using the camera in strong light conditions, check that you are using a DC-Iris lens, and that the settings for the lens are correct, i.e. in the Image-Advanced settings, the exposure control should be set to DC-Iris.Note: damage caused to the AXIS 2420 through overexposure to direct sunlight or halogen light is not covered under the product warranty.
Bad focus. The focus has not been correctly adjusted.	Referring to the on-line help, adjust the White Balance setting and then try resetting the camera focus again using the Focus Assistant, as described in Lenses and Advanced Focusing, on page 54.
	No adaptor fitted with your C-type lens.	Fit the required adaptor. See page 54.
Noisy images. Images may be noisy if you are using the AXIS 2420 in an environment with very low lighting.	To solve this problem, you need more light. The performance of the camera is best in 100 - 3.000 lux. Consider using a more sensitive lens (Lower F-number) if the lighting conditions within the installation area cannot be improved.

Symptoms Possible causes Remedial actions

Bad quality images. The Display Properties are incorrectly configured for your computer screen.	Open the Display Properties for your screen and configure it to show at least 65000 colors, i.e. at least 16-bit.Note: Using only 16 or 256 colors on your screen will produce dithering artifacts in the image.
	The camera is not focused correctly.
No images available in your browser application.	ActiveX disabled. If you are using Microsoft Internet Explorer, ensure that ActiveX has not been disabled.
	Java disabled. If using the Java Applet for viewing images, check that Java is enabled in your browser.

Note: If you still have a problem after reading this information, please contact your reseller or check the FAQ on the Axis Website at www.axis.com.

Appendix B - Other IP Setup Methods

In addition to the ARP command (described earlier in the Installation section of this manual), you can alternatively set the IP address for your AXIS 2420 using any of the following methods - as appropriate for your operating system:

Method Operating Systems Refer to...

AXIS IP Installer	Windows	Using the AXIS IP Installer, on page 52.
BOOTPRequiring a BOOTP daemon on your system, this method operates over the entire network. A request to an active daemon initiates a search of the boot table to find an entry matching the unit's Ethernet address. The daemon replies with the IP address for the device, if a match is found.	UNIX
DHCPThis method should only be used if you know which IP address the DHCP server will give the camera, or if your version of DHCP can update a DNS server, which then allows you to access the camera using a name.	Most

Notes:

• Do not use the default IP address featured in these examples when installing your AXIS 2420. If in doubt, consult your network administrator to obtain an unused IP address.
• Make sure the AXIS 2420 is powered up and attached to the network.
• Server Privileges: Although no special privileges are required for Windows 95/98/ME, you do need Administrator privileges for Windows NT/2000 and XP (Professional). UNIX systems require Root privileges.

Ethernet Address: The AXIS 2420 is pre-configured with a unique Ethernet Address based upon the serial number printed on the underside label of the unit; where the serial number typically follows the format 00-40-8c-xx-yy-zz. You must know the Ethernet address to complete the installation.

Using the AXIS IP Installer

AXIS IP Installer is a Windows program that is ideal for setting the IP addresses for multiple Axis networking products on your network. Also allowing you to access the home page of any Axis ThinServer device connected to your network, this freely distributed software is available for download from www.axis.com.

Installing the AXIS IP Installer:

1. Download the latest version of the AXIS IP Installer and run the Setup_IPInstaller.exe program to start the installation.
2. The AXIS IP Installer - Setup dialog is displayed on the screen.
3. Follow the instructions as they appear on the screen.

For more help during the installation of the IP address, click Help or press the F1 key.

Notes for Macintosh Users

The AXIS 2420 supports TCP/IP over Ethernet, or PPP Modem dial-up. You must use TCP/IP on your Macintosh network, as there is no support for AppleTalk.

When using the AXIS 2420 on a Macintosh, please observe the following points:

• The camera has a default IP address of 192.36.253.80.
• Assign a temporary IP address to a Mac workstation in the same subnet (e.g. 192.36.253.81) and then connect to the camera.
• Run the Installation wizard and set the desired IP address for the camera.
• Reset the correct IP address for the Macintosh workstation.
• Changing the IP address for a Macintosh does not require a reboot.

Currently there are limitations in the ActiveX Support in Internet Explorer running on the Macintosh. This results in problems when viewing live moving images. The recommended solution for viewing Axis cameras on the Macintosh is to use Netscape.

Appendix C - Lenses and Advanced Focusing

Your camera was supplied either without a lens (AXIS 2420), or with a DC-Iris lens (AXIS 2420 W/Lens). Either model can be fitted with any standard CS/C lens. The DC-Iris support included with the AXIS 2420 will drive any standard DC-Iris lens.

Fitting a Lens

Note: The AXIS 2420 is equipped with a CS-mount, so any standard CS lens can be fitted directly. To mount a C-type lens, a CS-C adapter must also be used. The adapter effectively moves the lens 5mm away from the camera's CCD.

Follow the instructions below to fit any C or CS type lens:

1. C-lens only: Attach the new lens to a CS-C Adapter.
2. Screw the lens onto the AXIS 2420. If applicable, adjust the iris according to the prevailing light conditions.
3. Referring to Focusing Procedure, on page 56, adjust the camera focus.
4. Adjust the DC-Iris settings. See page 57.
5. Refresh your browser and check the results from the camera's Home Page.

Caution!

Exposing your camera to bright sunlight may cause permanent damage to the CCD if you:

• use a non-DC Iris lens, or
• select anything other than DC-Iris in the Exposure Control settings of the Image - Advanced page.

Axis consequently advises extreme caution when fitting a lens to your AXIS 2420 and/or when using the Image - Advanced settings. Damage caused to the AXIS 2420 through overexposure to direct sunlight or halogen light is not covered under the product warranty.

Direct Focusing in Your Browser

The AXIS 2420 is easily targeted for different applications. With your video stream displayed in a browser, simply adjust the camera focus ring until you are satisfied with the focus.

However, for remote installations - where you are unable to view your video images directly in a browser - you can achieve a good level of camera focus by using the Focus Assistant, described below.

Notes:

- The text information printed on the lens assembly will clearly define the focusing polarity (F, , and N) for the focus ring supplied with your unit. The camera focus is adjusted for either Far-focus (F, ) or Near-focus (N) by rotating the focus ring in the appropriate direction.

- The lens rotates on a screw fitting and can be completely removed. If you need to remove the lens, take care not to let any dust enter the lens or the camera window as this can adversely affect the quality of your live images.

Important!

The illustration below is displayed as an example of a commonly available lens type, but is NOT typical for all lens types.

Using The Focus Assistant

Important!

As an alternative to the procedures described here, you can also enable and use the Focus Assistant directly from the Administration Tools. For more information on this, please refer to the on-line help.

Enabled manually using the Control Button (or via the administration Web pages), the Focus Assistant works in conjunction with the Status Indicator to provide an onboard visual display for focusing your camera. With the Focus Assistant enabled, the Status Indicator displays Green when the camera is focused - which means you can conveniently focus the AXIS 2420 without having to monitor the images in a desktop browser.

Focusing Quality

The table below show the full range of colors displayed by the Status Indicator when the Focus Assistant is enabled; where each color represents a predefined level of focus:

Color Level of Focus (%) Focus Quality

Red 0 - 60 Poor
Yellow 60 - 80 Reasonable
Green 80 - 100 Good

Plane of Focus

The lens has rotational focus control that allows the focal length of the lens to be adjusted manually. Depending on the chosen physical location for your camera, it is likely that several planes of focus will exist throughout the full focusing depth of the unit; consequently, the Status Indicator is likely to display green - indicating a good level of focus - several times throughout the full travel of the lens assembly.

Focusing Procedure

Before you begin:

For the focusing algorithm to work efficiently, always ensure that there is minimal movement in the camera's field of view when focusing, as described below.

With reference to the accompanying illustrations, follow the instructions below to achieve a good basic level of focus under stable conditions:

Important!

Do not press the Control Button for at least 10 seconds after powering up the unit, as this will cause the AXIS 2420 to return to its factory default settings.

1. Power up the AXIS 2420 and then wait at least 10 seconds.
2. Turn the lens to its extreme Far-focus (F, ) position.
3. Enable the Focus Assistant. Using a suitably pointed object, press and continue to hold the Control Button - until the Status Indicator flashes Yellow. The Focus Assistant is now enabled with the Status Indicator set to Focus Mode. The AXIS 2420 now initiates a focusing algorithm to regularly calculate the quality of focus.
4. In order for the Focus Assistant to access the full focusing range for your application environment, turn the lens slowly to its extreme Near-focus (N) position.

Control Button

1. Finally, turn the lens slowly towards the Far-focus (F, ) position, until the Status Indicator displays Green; that is, until a Good level of focus is achieved.

Notes:

• A Good level of focus is normally achievable throughout several planes within the focusing range of the camera.
• The Status Indicator displays Green to indicate a Good level of focus at 80% of optimum focus.

• Since optimum focusing is dependent upon the camera's field of view, it is important to scan the focusing plane from the furthest to the closest perspectives before attempting any fine-tuning.

• Return to your browser and review the picture quality. Repeat step 5 only if you consider the focal distance too distant - until you are satisfied with both the focal-distance and focus-quality.

• To exit the Focus Assistant: press and hold the Control button - until the Status Indicator flashes Yellow. The Status Indicator displays Green when the Focus Assistant is closed.

Adjusting the DC-Iris Settings

The DC-Iris settings must be adjusted to meet the requirements of the lens you intend to use. You will need to modify the Exposure Control and other related settings for your camera, from the Image-Advanced page.

Use the information presented in the following tables to choose the appropriate settings for your lens type.

Caution!

Exposing your camera to bright sunlight may cause permanent damage to the CCD if you:

• install and use a non-DC Iris lens with the product, or
• select anything other than DC-Iris in the Exposure Control settings of the Image - Advanced page.

Axis consequently advises extreme caution when changing the lens and/or when using the Advanced settings. Damage caused to the AXIS 2420 through overexposure to direct sunlight or halogen light is not covered under the product warranty.

Exposure Control Overview

The table below provides a summary of the Exposure Control settings in the Image - Advanced page. Select the parameters for your lens type and product application.

Lens Options Description

DC-Iris	The DC-Iris setting is the standard factory default setting found on the Image-Advanced page. It allows the user to manually specify the exposure, shutter speed, gain, and ALC levels.
Non-DC-Iris - Manual	Choose this setting if you have fitted a non-DC-Iris lens to your AXIS 2420, but wish to adjust the shutter speed and gain manually.
Non-DC-Iris - Shutter	Choose this setting if you have fitted a non-DC-Iris lens to your AXIS 2420 but wish to adjust the shutter speed manually.
Non-DC-Iris - Auto	Choose this setting if you have fitted a non-DC-Iris lens to your AXIS 2420 and would like the shutter speed and gain to be adjusted automatically.

Other Advanced Parameters

Lens Options Description

Shutter Speed	Derived from the shutter speed on a normal camera, this parameter defines the exposure period for each image. Use a high shutter speed only if your image subject is expected to be moving quickly; otherwise, a slower speed will normally suffice.
Sharpness	Defines a level of differentiation between light and dark areas within the image. Corresponding higher levels of sharpness provide for sharper images, but also cause the image compression to be more complex. Consequently, the file size of a sharp image can be significantly greater than an image that is less sharp.
Gain	Adjust the gain to suit the average level of light at your point of installation. The AXIS 2420 should be set to a corresponding higher level of Gain if your camera is normally monitoring an area at night, or is situated in a dark room or cupboard.
ALC Level	This defines how acutely the lens reacts to a single light source within the image. For example, with the ALC level set at a higher level, the headlights from a car will generally cause the calculated average level of light to increase, and subsequently result in a compensated image that is usually much darker.Adjusting the ALC to a lower level reduces the sensitivity of the lens to single light sources within the image.

Adjusting the Back Focus

Your AXIS 2420 is supplied with the back focus roughly set to accommodate a reasonable level of focus throughout the complete focusing range. However, if you are dissatisfied with the quality of focusing at a specific plane (or at several planes) within the focusing range, you may need to make some fine adjustments to the back focusing of the lens. This is performed by adjusting the focus and zoom rings of the camera lens, as described below:

Procedure

1. With the Focus Ring set to the Far-focus (F, ∞) position, aim the camera at a subject over 30 metres away.
2. Set the lens assembly to wide angle, and adjust the back focus by loosening the Lock Ring and then turning the lens assembly. Continue to turn the lens assembly until you achieve optimum image clarity
3. Check that you obtain sharp pictures at various zoom grades and various distances.

Note:

If possible, it is better to perform this adjustment in low light conditions, or with a filter covering the front optic. This will ensure the iris is fully open to give the smallest depth of field, and therefore the best result.

Appendix D - Customizing Your Camera

Modifying the File System

The Linux-based operating system and flash memory file system make it possible for advanced users and application developers to customize the AXIS 2420 by adding additional files to the read-write area of the flash memory.

Important!

• Modification of the flash file system is NOT supported by Axis. In practice, this means that Axis will not answer questions relating to custom script or Web page development, but merely wishes to inform potential application developers of the possibilities afforded by the Linux-based file structure of the AXIS 2420.
• When attempting to modify the product, you may inadvertently create a problem that will require you to return the AXIS 2420 to its factory default settings. At worst, you may even cause permanent damage to the unit that renders it unusable. Consequently, Axis strongly recommends that inexperienced users DO NOT modify the file system.

Although modification of the file system is not supported, the Axis web at www.axis.com does maintain various documents designed to assist third-party development. These include detailed information such as:

• The Axis Camera API, HTTP-Interface Specification
• A description of the reduced PHP3 scripting language

Configuration using FTP

As an alternative to configuring the AXIS 2420 from a browser, the configuration parameters of your camera can be modified using the File Transfer Protocol (FTP).

FTP is supported by most operating environments and is a useful method for quickly uploading standard pre-configurations to one or more cameras.

Custom Web Pages

The AXIS 2420 contains a re-writable flash memory file system that allows some directories and files to be changed by the root user, using FTP. This strictly non-supported product functionality makes it possible for advanced users and application developers to add their own Web pages, scripts, and other files to the Axis product.

Customizing Procedures

The existing Administration pages are stored in a compressed read-only area of the file system. If you intend to try changing these pages, you must adhere strictly to the instructions provided here and ensure that you DO NOT inadvertently change any files other than those featured in this section. Failure to comply with this notice may render your product unusable.

All files stored in the /etc/httpd/html directory are available through the product Web server in the virtual directory /local/. The URL to resident pages in the /etc/httpd/html directory is http://IP/local/.htm

You can change the html files as and when you like, but remember that the available flash memory is limited. The number of times the memory can be written to is approximately 1 million.

Creating a New Home Page

Having created and stored your new custom Web pages in product memory, you then proceed to assign one of these pages as your default Home page in the AXIS 2420, as described below:

Caution!

Adding a new Web page to your AXIS 2420 is not something that should be undertaken lightly. Remember: Axis does not support the personalization of product Web pages and strongly recommends that inexperienced users DO NOT perform such modifications.

1. Start a new FTP session to the AXIS 2420, by entering:

ftp <camera ip address> 

1. Type bin
2. Navigate your way to the appropriate directory, entering:

cd /etc/httpd/conf/ 

1. Fetch the boa.conf file, by typing:

get boa.conf 

1. Edit boa.conf and add the following lines to the end of the file:

Alias /index.html /etc/httpd/html/index.html
Alias / /etc/httpd/html 

This will create an alias to your own "homemade" index.html file stored in the /etc/httpd/html/ directory and redirect access to it. Replace the edited boa.conf in the camera, by using the put command.

1. Restart the camera.

Note: As an alternative to the above, you might like to edit the line starting with Document Root so that it points directly to the local directory. However, after doing this you will then be unable to access the original Home pages - so be warned!

1. After making these changes, you will not be able to automatically access the default index page. Instead you must type in the complete URL to access it:

http://IP-address/view/index.html 

Appendix E - Updating the Firmware

The AXIS 2420 camera firmware is stored in Flash memory. This memory is provided by a silicon chip that, just like any other ROM device, retains data content even after power is removed. Flash memory is unique because it allows its data to be erased and re-written. This means that you can install firmware updates for your AXIS 2420 as soon as they become available - without having to replace any parts. New firmware can be simply loaded into the AXIS 2420 over the network.

Obtaining Updated Firmware

The latest version of the AXIS 2420 camera firmware is available free of charge from the Axis website at www.axis.com or from your local distributor.

Upgrading

The AXIS 2420 Flash memory is upgraded over the network using FTP. See the detailed instructions supplied with each new firmware release.

Important!

• Always read the instructions available with each new release, prior to upgrading.
• Upgrading normally takes at least 30 seconds and up to 10 minutes, although it can take longer. After starting the process, you should always wait at least 20 minutes before power cycling the AXIS 2420 - even if you suspect the upgrade procedure has failed.
• In controlled environments, flash memory upgrades provide a very safe method for updating firmware. However, flash products can become damaged if the upgrade operation is not performed correctly. Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the user.

Appendix F - The Unit Connectors

This section provides an overview of the product connectors, namely:

• 1 x RS-232 Serial Connector
• 2 × I/O Connectors (I/O-A and I/O-B)
• 1 x DC-Iris Connector
• 1 x BNC Video Output
• 1 x Ethernet network connector (RJ-45)

The RS-232 Serial Connector

In the absence of a local network connection, a single 9-pin D-sub connector provides a dedicated physical interface for connecting a modem or computer to the AXIS 2420. This RS-232 interface supports modem speeds of up to 115kbps and effectively allows the AXIS 2420 to operate as a standalone unit independent of any computer network. So, when a local network connection is unavailable at the point of installation, you can simply connect your PC to this connector and use the supplied Null Modem Cable to initially configure your product. If you intend using the AXIS 2191 Audio Module with your network camera, then this is the connector to use.

Note: The Axis Camera Division maintains a list of all supported modems. Please visit our Website at www.axis.com for this and other late information on our products.

Pinout Information

A diagram of the RS-232 connector, complete with pinout information, is shown below.

The I/O-A Connector

Used for connecting external alarm devices and triggering images for alarm-based events, the 4-pole I/O-A Connector provides the interface for a single digital input. Connected to a switch or other external security device, an image is recorded every time the switch is activated. It also provides an auxiliary DC power input or output for the AXIS 2420.

Pinout Information

Pin Function

4 Digital Input - Photocoupled Cathode (-) As below.
3 Digital Input - Photocoupled Anode (+)

Electrically isolated from the chassis and connectors, this input can be supplied from an external DC voltage or the DC power input/output on pin 2.

2 Positive Connection for DC power input or output:

Electrically in parallel with the derived DC power for the unit, this pin can be used as an input or output. As an input it can be used for remote applications to supply the AXIS 2420 via an external direct current source; for example, a 9-15V DC battery supply. Used as an output, it can drive the photocoupled input or other equipment; such as a thermal sensor. The output voltage level is dependent upon the input voltage to the unit. A maximum current of 50mA can be sourced from the DC output.

Caution!

Pin 2 is connected to the derived DC power for the unit, and can be used as an external power feed for external equipment, such as an Infrared sensor. When connecting other equipment using this connector, the maximum current of 50mA must be strictly observed. Failure to do this may cause a loss of power to the unit and even damage it.

The I/O-B Connector

The 4-pole I/O-B connector provides a digital relay switch for the control of external surveillance devices and services; such as, lighting, annunciators, audible alarms, etc. It is also an RS-485/422 port for the control of pan tilt devices, etc. A pinout table is provided below.

The DC-Iris Connector

The AXIS 2420 can be used with any standard C/CS lens. With full support for standard DC-Iris lenses, the camera will automatically regulate the amount of light entering the camera.

The DC-Iris Connector provides the power and control signalling required for a DC-Iris lens. The connector is located on the rear panel and the pinout for the connector is shown below.

Pin Function

1 Control and detection (-)
2 Control and detection (+)
3 Motor (+)
4 Motor (-)

Soldering side of connector

The BNC Video Output

The BNC Video Output can be used for connecting the AXIS 2420 to a traditional analog CCTV system or to a VCR. This output can be used independently of the Ethernet network connector and both can be used at the same time. The output conforms to 1.0V (p-p) 75 Ohms, sync negative.

The Ethernet Network Connector

The RJ-45 network connector is used to connect the AXIS 2420 to a 10/100Mbit Ethernet network running TCP/IP.

Control and Monitoring

You can enable IO Status to display ON/OFF buttons for driving the Digital Output from the Layout section of the Administration Tools on the Home Page of the AXIS 2420.

By entering http requests in your browser's URL field, you can:

• drive the relay output high or low
• monitor the status of the digital input

This requires you to have root access to the AXIS 2420 and consequently, to supply a user name and password. Login as root and supply the root password (default = pass).

Tip!

Developers wishing to create applications incorporating sophisticated alarm conditioning using the relay output and digital input are encouraged to read the Camera API, HTTP-Interface Specification, available from the Axis Web at www.axis.com.

Relay Output

You can use the supported relay output to directly drive a maximum load of 24V AC/DC at 100mA. By connecting additional relay circuitry, it can also drive heavier loads.

The output relay is controlled using http requests, as defined in the following examples:

Example 1: - Set output 1 ON.

http://myserver/axis-cgi/io/output.cgi?action=1:/ 

Example 2: - Set two 300ms pulses with 500ms delay between the pulses on output 1.

http://myserver/axis-cgi/io/output.cgi?action=1:/300\500/300\ 

Example 3: - Wait 1 second before setting output 1 ON.

http://myserver/axis-cgi/io/output.cgi?action=1:1000/ 

Digital Input

The digital input, programmed using the Application Wizard, allows the AXIS 2420 to be configured for time and alarm based image recording. For example, by connecting a motion detector to the digital input, it is a relatively simple procedure to send a single image (or video stream) to a remote imaging library each time the detector is activated.

Querying the Status of the Digital Input

The status of the digital input can be queried in exactly the same way as the relay output. Simply enter the following URL to query the status of the digital input:

Example: - Monitor data on port 1

http://myserver/axis-cgi/io/input.cgi?check=1 

The AXIS 2420 then displays the status of the input, as follows:

The AXIS 2420 is designed with high-speed Internet services foremost in mind, and you will experience the full performance of your AXIS 2420 if you are fortunate enough to have xDSL or a cable modem connection. However, as most high-speed Internet services only provide you with one external IP address, there are some practical issues that should be considered when developing your application. This section discusses some of these issues.

Available IP Addresses

Ideally your ISP (Internet Service Provider) should supply you with several external, static IP addresses - in which case you can assign any one of these to your AXIS 2420 to make it fully accessible over the internet. If your ISP supplies you with only one IP number - which is usually the case - then this IP number is normally assigned to your PC. If your ISP is unable to provide you with an additional IP number, you still have a number of other options that you may like to consider, including:

Windows 2000 NAT-feature (Network Address Translation):

Utilize the NAT feature in Windows 2000 to allow multiple Ethernet cards in your PC. You then use one port for the Internet and the other for your internal network. Using this solution, you can let your AXIS 2420 upload image streams to your ISP's external Web server.

Routers and Firewalls

Another ideal solution is to use one of several small routers/firewalls that are currently available on the market. These provide the necessary NAT functionality and allow complete independence for your PC, which can be switched off or rebooted without affecting the image transmission from your AXIS 2420.

WinGate Server Software:

Running on a single Windows computer, this software allows multiple users simultaneous access to the Internet through a single connection; be it modem, ISDN or high speed line, such as xDSL or cable modem connection. You can thus effectively share a single Internet connection with almost any type of client computer running TCP/IP.

For more advanced users, the WinGate 3.0 Standard and Pro versions allow the administrator to change the IP bindings so that external requests may be routed specifically to your AXIS 2420 - running behind the WinGate software.
