Introduction
The DCS-6616 Speed Dome Network Camera is a professional IP surveillance solution that connects to your network to provide high-quality live video over the Internet. The camera supports precise high-speed pan/tilt/zoom functionality for extensive monitoring and object tracking.
Hardware Overview

Resetting the Camera
The DCS-6616 contains both digital and mechanical components. Thus, if any problems are experienced with the camera, there are two different reset options depending on the type of problem.
Mechanical Reset
If the mechanical PTZ controls ever stop responding or seem to be locked up, you may reset the mechanical portion of the camera using the communication pin array at the base of the device.
- Use a small tool to move switch 5 to the "off" position.
- Plug the camera in for one minute and allow the device to initialize.
- Return the pin back to its original "on" position.
- Plug in the camera, and the device should successfully initialize.

Digital Reset
If the camera's web user interface ever becomes unresponsive, or if the administrator password is forgotten, it may become necessary to reset the device firmware to its original factory settings.
- Press and hold the green button on the base of the camera for a few seconds.
- Allow a few minutes for the camera to re-initialize to factory default settings.

Application
In a typical application, when motion is detected, the DCS-6616 Network Camera sends images to a FTP server or via e-mail as notifications. As shown in the illustration below, an event can be triggered by many sources, such as motion detection or external digital input devices. When an event is triggered, a specified action will be performed. You can configure the Network Camera to send snapshots or videos to your e-mail address or FTP site.

For example:
If both the Send pre-event images and Send post-event images are set to four, a total of 9 images are generated after a trigger is activated.

Add a date and time suffix to the file name
Select this option to add a date and time to the file name suffix.

Maximum duration
Specify the maximal recording duration in seconds. You can set up to ten seconds.
For example:
If the Pre-event recording is set to five seconds and the Maximum duration is set to ten seconds, the Network Camera continues to record for another four seconds after a trigger is activated.

for another four seconds after a trigger is activated.

File name prefix
Enter the text that will be added at the beginning of the file name.

Add Event
Create and schedule up to three events with their own settings here.
Event name: Enter a name for the event.
Enable this event: Select this box to activate this event.
Priority: Set the priority for this event. The event with higher priority will be executed first.
Delay: Select the delay time before checking the next event. It is used for both events of motion detection and digital input trigger.
Trigger: Specify the input type that triggers the event.
Video Motion: Motion is detected during live video monitoring. Select the windows that need to be monitored.
Periodic: The event is triggered in specified intervals. The trigger interval unit is in minutes.
Digital Input: The external digital input trigger input to the camera.
System Boot: Triggers an event when the system boots up.
Network Lost: Triggers an event when the network is lost.
Time: Select Always or enter the time interval.
Trigger D/O: Select to trigger the digital output for a specific number of seconds when an event occurs.

Recording
Here you can configure and schedule the recording settings.
Recording entry
name: The unique name of the entry.
Enable this
recording: Select this to enable the recording function.
Priority: Set the priority for this entry. The entry with a higher priority value will be executed first.
Source: The source of the stream.
Recording
schedule: Scheduling the recording entry.
Recording settings: Configuring the setting for the recording.
Destination: Select the folder where the recording file will be stored.

Total cycling size: Please input a volume size between 1MB and 200GB for recording space. The recording data will replace the oldest recording when the total recording size exceeds this value. For example, if each recording file is 6MB, and the total cyclic recording size is 600MB, then the camera will record 100 files in the specified location (folder) and then will delete the oldest file and create new file for cyclic recording.
Please note that if there is not enough free space, the recording will stop. Before you set up this option please make sure that sufficient free space is available. It is better to not save other files in the same folder as recordings.
Size of each file for
recording: File size for each recording file. You may input the value in the range of 200-5000.
File Name Prefix: The prefix name will be added to the file name of the recording file(s).
Advanced DI and DO (Digital Input/Output)
The camera provides eight alarm inputs and one alarm output to connect alarm devices. With this function, the camera can cooperate with the alarm system to capture event images.
No. # DI Type: Normal Open is for digital input that is activated when the circuit is closed.
Normal Close is for digital input that is activated when the circuit is opened.
For example: Connect the Alarm input terminal to ALM GND to activate [NC] or floating (unconnected) [NO] to deactivate.


ICR
The Infrared Cut-Removable (ICR) filter can be disengaged for increased sensitivity in low light environments. The ICR filter will automatically engage depending on the ambient light, allowing the camera to be effective in day/night environments.
Automatic (Default): The day/night mode is set automatically. It will typically use day mode, but will use night mode if installed in a dark area.
Day Mode: The Day mode disables the IR Cut Filter.
Night Mode: The Night mode enables the IR Cut Filter.
Schedule Mode: You can specify a time period for which Day mode will always be used.

HTTPS
This page allows you to install and activate an HTTPS certificate for secure access to your camera.
Enable HTTPS
Secure Connection: Enable the HTTPS service.
Create Certificate: Choose how the certificate should be created. Three methods are available:
Create a self-signed certificate automatically Create a self-signed certificate manually Create a certificate request and install
Status: Displays the status of the certificate.
Note: The certificate cannot be removed while HTTPS is still enabled. To remove the certificate, you must first uncheck Enable HTTPS secure connection.
