- Connect the BNC video output cable from the camera to your DVR/HVR or monitor.
4.4 Selecting Video Format (DIP Switch)
The camera supports CVI, TVI, AHD, and CVBS video formats. The desired format is selected using a DIP switch located on the camera cable or body. Refer to the specific markings on the camera or its cable for the correct DIP switch settings for each format. Ensure the camera is powered off before changing DIP switch settings.
5. Operating the Camera
5.1 Accessing the OSD Menu
The camera's On-Screen Display (OSD) menu allows for configuration of various image settings and functions. The OSD menu is typically accessed via the connected DVR/HVR's control interface (e.g., UTC controller or coaxial control).
Common OSD menu options include:
- Day/Night Mode: Auto, Color, Black/White, or external control.
- Exposure Settings: Adjust shutter speed, AGC (Automatic Gain Control).
- White Balance: Auto, Manual, or Area-based settings.
- Image Enhancements: BLC (Backlight Compensation), HLC (Highlight Compensation), DWDR (Digital Wide Dynamic Range), 2DNR (2D Digital Noise Reduction).
- Smart IR: Controls the intensity of the infrared LEDs to prevent overexposure in close-up scenes.
- Motion Detection: Configure detection zones and sensitivity.
- Privacy Masking: Define up to 8 rectangular areas to block from view for privacy.
5.2 Smart IR Functionality
The Smart IR feature automatically adjusts the intensity of the camera's infrared LEDs to ensure uniform illumination in low-light conditions. This prevents objects close to the camera from being overexposed, which can happen with traditional IR illumination.
6. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your camera.
- Cleaning: Periodically clean the camera lens and housing with a soft, damp cloth. Avoid abrasive cleaners that could scratch the lens.
- Cable Inspection: Check all power and video cables for any signs of wear, damage, or loose connections.
- Mounting Security: Ensure the camera remains securely mounted and that all adjustment screws are tight.
- Software Updates: Check the manufacturer's website for any firmware updates for your camera or connected DVR/HVR.
7. Troubleshooting
If you encounter issues with your camera, refer to the following common troubleshooting steps:
- No Image/Black Screen:
- Verify the power supply is connected and providing the correct voltage (12 VDC).
- Check the video cable connection between the camera and the DVR/HVR.
- Ensure the correct video format (CVI/TVI/AHD/CVBS) is selected via the DIP switch, matching your DVR/HVR.
- Poor Image Quality:
- Clean the camera lens.
- Check for obstructions in the camera's field of view.
- Adjust OSD settings such as brightness, contrast, and sharpness.
- Ensure the camera is receiving adequate power.
- Night Vision Issues:
