5. Setup and Installation
5.1 Physical Connections
Identify the various ports on the rear panel of the camera for proper connection.

- Power Connection: Connect the supplied DC12V 1A power adapter to the 'DC12V' input port.
- Video Output (SDI): Connect an SDI cable from the 'SDI' output port to your SDI monitor, recorder, or switcher.
- Video Output (CVBS): For analog video output, connect a BNC to RCA cable (not included) from the 'CVBS' output port to a composite video input on a TV or monitor. This output can be particularly useful for initial setup and OSD menu access if the SDI signal is not yet configured.
- OSD Menu Control: The 'OSD' button allows access to the camera's On-Screen Display menu for configuration.
- IRIS: This port is for connecting an auto-iris lens if applicable. The included lens is manual varifocal with auto iris, so this port may not be used for the standard setup.

5.2 Mounting and Lens Adjustment
The camera is designed for versatile mounting. Ensure it is securely fastened to a stable surface or bracket. The 2.8-12mm varifocal lens allows you to manually adjust the field of view and focus to suit your surveillance needs.

- Zoom Adjustment: Rotate the zoom ring on the lens to adjust the focal length (2.8mm for wide angle, 12mm for telephoto).
- Focus Adjustment: After setting the desired zoom, rotate the focus ring until the image is sharp and clear.
6. Operating Instructions
6.1 Powering On
Once the power adapter is connected, the camera will power on automatically. The power indicator light on the rear panel will illuminate.
6.2 Accessing the OSD Menu
The On-Screen Display (OSD) menu allows you to configure various camera settings. To access the OSD menu, press the 'OSD' button on the rear panel. Use the directional controls (usually by pushing and tilting the OSD button) to navigate through the menu options and confirm selections.
Important Note: Some users have reported issues with SDI output not working until the frame rate is adjusted in the OSD menu. If you experience no SDI signal, connect the camera via the CVBS output to a composite video input on a TV or monitor to access the OSD menu. Navigate to the 'System' submenu and change the 'Frame Rate' from 1080_60P to 1080_60I or a lower compatible resolution (e.g., 1080p 30Hz) for your SDI receiver.
6.3 Basic Menu Navigation (Blind Operation)
In situations where you cannot see the OSD menu (e.g., no signal on SDI/CVBS), you may attempt to change settings blindly using a known button sequence. This sequence is provided as a last resort and may vary slightly. The following sequence is reported to change the resolution to a more compatible setting:
Push → Up → Up → Push → Down → Down → Down → Right (x2 or more)
Ensure at least a 1-second delay between each button press. This sequence is for changing resolution settings and may not apply to all menu structures.
6.4 Image Settings
Within the OSD menu, you can adjust various image parameters:
- White Balance: Set to Auto Tracking White Balance for most scenarios. Manual adjustments are available if needed.
- Backlight Compensation (BLC): Set to Auto to optimize image visibility in scenes with strong backlighting.
- Noise Reduction: Adjust 3D DNR settings to reduce image noise, especially in low-light conditions.
- Exposure: Control brightness and shutter speed.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the camera body. For the lens, use a specialized lens cleaning cloth and solution. Avoid harsh chemicals or abrasive materials.
- Environmental Conditions: Ensure the camera operates within its specified working temperature range (-10℃~60℃). Avoid exposing the camera to extreme temperatures, humidity, or direct water.
- Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to ensure optimal performance and access to new features.
