4.2 Connecting and Testing Analog Cameras
The Anpviz IV8-GM tester supports various analog camera types. Follow these steps to connect and test your camera:
- Connect the BNC cable from your analog camera to the "Video Input" port on the tester.
- If the camera requires power, use the DC12V output cable from the tester to power the camera.
- Power on the tester. The screen should display the camera's video feed.
- If the image appears black and white or distorted, the signal format may not correspond. Use the "MODE" button to cycle through AHD, TVI, CVI, and CVBS modes until a clear image is displayed.

4.5 VGA/HDMI Input Usage
The tester can function as a display for DVRs or NVRs. Connect an HDMI or VGA cable from your DVR/NVR to the corresponding input port on the tester. Use the VGA/HDMI switch to select the correct input mode.
5. Troubleshooting
- No Image on Screen:
- Ensure the battery protective film has been removed and the device is charged.
- Verify the camera is properly connected to the "Video Input" port.
- If the image appears black and white or distorted, it may be that the signal does not correspond. Switch the tester signal to be the same as the camera signal to solve the problem. Use the "MODE" button to cycle through AHD, TVI, CVI, and CVBS modes.
- Confirm the camera is receiving power, either from the tester's DC12V output or an external power source.
- IP Camera Not Supported:
- This Anpviz IV8-GM tester is designed exclusively for analog CCTV cameras (AHD/TVI/CVI/CVBS) and does NOT support IP PoE cameras.
- HDMI/VGA Input Not Recognized:
- If HDMI is used as the display input, it can only be connected to an NVR or DVR which has an input signal of HDMI.
- If HDMI is a signal output, it needs to be connected to a display or TV.
- Ensure the correct input mode (VGA or HDMI) is selected using the switch on the tester.
- Battery Not Charging/Device Not Turning On (Battery Power):
- Ensure the battery protective film has been removed.
- If the battery power is insufficient, connect the charger. Fully charge the device before unplugging and using it.
