Defender HD | How to Troubleshoot Video Loss or No Picture
In this video, we’ll walk you through the process of troubleshooting a blank camera image or loss of video signal on Defender HD.
Video loss on a surveillance system can manifest as a black screen and may occur after moving components or cables. The most common cause of video loss is loose connections or a loss of power.
To find the cause of the issue, follow these steps.
Confirm the DVR is not set to Covert mode – this setting can be found in the display section of the Parameter menu. Enabling Covert mode turns off the camera display, but the camera will still record as shown by a red M or R icon on screen.
- Check that all connections are tight:
- Camera to DVR.
- Camera to Power Splitter.
- Power Splitter to Power Adapter.
- Power adapter to wall outlet.
- Unplug the camera from power and plug it back in.
- Switch the Yellow BNC connection on the back of the DVR to a known working video channel
- Remove the camera and power adapter from the four-way power splitter.
- Connect the non-working camera directly to the power adapter.
If the camera view is still blank. Please reach out to our Customer Experience team for further assistance.
