according to the IEC60950-1 standard; or 802.3af PoE. Please refer to technical specifications for detailed information.
- If connecting several devices to one power supply, to avoid any overload that may cause over-heating or a fire hazard insure that the power supply is adequate for the power load.
- Please make sure that all plugs are firmly connected to the power sockets. When the product is mounted on wall or ceiling, the device shall be firmly attached, taking into consideration any wind, snow loading, or other factors.

Cautions
- Make sure the power supply voltage is correct before using the camera.
- Do not drop the camera or subject it to physical shock.
- Do not touch lenses or sensor modules with fingers. If cleaning is necessary, use clean cloth with a bit of ethanol and wipe gently. If the camera will not be used for an extended period, please protect the lens openings from damage and/or debris.
- Avoid aiming the camera at the sun or extremely bright light sources. Blooming or smearing may occur in excessive light
(which is not a malfunction), and could compromise the performance of the sensor.
- The sensor may be damaged if exposed to laser energy, so when any laser equipment is in use, make sure that the sensor will not be exposed to the laser beam.
- Do not place the camera in extremely hot or cold (see camera specifications) locations. Do not exceed the rated environmental (IP66) conditions. Do not expose the camera to high levels of electromagnetic (RF) radiation.

2 Installation
Before you start:
● Make sure the camera is in good condition and all the accessory parts are included.
● Make sure all related equipment is powered-off during the installation.
- Check to insure that the specifications of the camera are correct for the installation environment.
● Make sure the power supply voltage is 12VDC or PoE compliant to avoid damage to the camera.
- If the product does not function properly, Dealers please contact KT&C; End Users please contact your KT&C Certified Dealer or an authorized service center. Do not disassemble the camera for repair or maintenance by yourself.
● Make sure that the mounting surface is strong enough to withstand three times the weight of the camera.

If the IR LEDS in this camera will be active, you must observe the following precautions to prevent IR reflection:
- Dust or grease on the lens/dome cover will cause IR reflection. Please do not remove the cover protective film until the installation is finished. If there is dust or grease on the lens/dome cover, clean the lens/dome cover with clean soft cloth and isopropyl alcohol.
- Make sure that there is no reflective surface too close to the camera lens. The IR light from the camera may reflect back into the lens causing haze, distortion or improper scene exposure.
- The foam ring around the lens must be seated flush against the inner surface of the cover/bubble to isolate the lens from the IR LEDs. Fasten the lens/dome cover to camera body so that the foam ring and the dome cover are attached seamlessly.

3 Setting the Camera Parameters over the LAN
Purpose:
To view and configure the camera via a LAN, you need to connect the network camera in the same subnet with your computer, and install the OMNI Finder or OMNI CMS software to search and change the IP of the network camera.
The following figure shows a camera and PC connected through a switch:
![graph LR A["Network Camera"] -->|Network cable| B["Switch"] B -->|Network cable| C["Computer"]](/content/2026/05/860926/images/b97d6d858cca3ece38671f9a5690f2d31f36935f048aee8c6cdf5d0ce9d2d465.jpg)
Figure 3-1 Typical LAN Connection
Set the IP address of the camera for accessing via LAN.
Steps:
- To get the IP address, you can choose either of the following methods:
☐ Use OMNI Finder, a software tool which can automatically detect network camera on the LAN and list device information such as IP address, subnet mask, port number, device serial number, device version, etc., as shown in Figure 3.2 below.
☐ Use OMNI CMS software and to list the online devices. Please refer to the user manual for the OMNI CMS software for detailed information.
- Change the IP address and subnet mask to the same subnet as that of your computer, or change your computer to match the address/subnet of the camera.
Refer to the following introductions to set IP address with OMNI Finder software:
□ Search active devices online
Search online devices automatically:
After launching the OMNI Finder software, it automatically searches for online devices every 15 seconds on the subnet where your computer is connected. It displays the total number and information of the discovered devices in the Online Devices interface. Device information including the device type, IP address, port number, gateway, etc. will be displayed.

Figure 3-2 Search Online Devices

Devices can be discovered and displayed in the list in 15 seconds after they go online; devices will be removed from the list in 45 seconds after going offline.
Search online devices manually:
You can also click to refresh the online device list manually. The newly searched devices will be added to the list.

You can click or on each column heading to order the information; you can click to show the device table and hide the network parameter panel on the right side, or click to show the network parameter panel.
1.2 Modify device information
