Place your eye up to your hands, keeping out as much light as possible.Cup your hands around the front of the camera.
To try to determine if the cameras are receiving power, we will look for activation of the nightvision IR LEDs. Checking our power input should be the first step. Obviously, without power, the cameras will fail to operate. If you get a menu, then you can close that and proceed with troubleshooting in this guide. If you do not see a menu (indeed, if you cannot see any camera divisions at all) then it is an issue with the screen and you will need to check your settings for output on the recorder. If you right-click with the mouse, you should see a response on the screen where you see a menu of some type. To determine if the video loss is related to the cameras, the quite simple test is to attempt to bring up the recorder’s menu screen. We will only be looking at camera video loss in this guide. This guide does not address the monitor video loss as the troubleshooting for that issue is generally straightforward and requires only a single change on the recorder. Camera video loss is where the cameras are unable to be seen on the recorder’s display (and by extension the attached screen). Monitor video loss is where the DVR is unable to be seen at all on the screen that is attached to the DVR. There are 2 types of video loss - cameras and monitor. Please note, this guide does *NOT* pertain to NVRs, which have some more complex rules to follow. However, if you skip steps, then you may well miss something simple, yet important. Some of the troubleshooting steps will seem quite simplistic and may be unnecessary. This guide will aim to provide some common troubleshooting actions for when one or more of your cameras connected to a DVR are not showing an image.
