Video loss in security cameras?
If you have issues with your security cameras and video not appearing on the DVR, you may need to replace the coax cables coming from your cameras.
To check what causes video loss in security cameras, you can do simple tests. Please note that we will be testing for signal loss at this point and no connection problems.
First, disconnect all cables between the cameras and DVR (including power) – it doesn’t matter if they’re working or not.
Reconnect them one by one checking each time for the video quality on the DVR. Once you’ve found which cable has no signal, mark that camera as “bad” and move on to another…
If your goal were to test for connection problems, you would need to do the same tests only using the cables between your cameras and their power supply – not with them powering down or up, but off.
If doing this does not produce any video on the DVR, it may be an issue of loose connections between your DVR and monitor/TV.
If you are still having issues with your security cameras even though they appear to be working correctly, then the problem may lie in signal interference.
It can occur when there is unnecessary metal near or touching your coaxial cables or if one of your components is faulty.
To check for metal interference, try moving all devices out of their current positions so that they are at least away from any metallic surfaces (doors, windows, cabinets, etc.).
If you are still not receiving any video, then it is time to test for faulty equipment – disconnect one of your cameras from the recorder and check if this results in a better camera-to-DVR connection.
How to fix CCTV camera video loss?
In case of some situation, for example, network failure, power cut off. The security DVR will stop recording any more clips and show “No Disk,” which means it cannot record anything from now on.
In this circumstance, the only way is to get back lost data by using a PC program or manually copying data from the hard drive if the computer can detect it.

Search for the video file you want to retrieve data from by clicking the “Search” button; if it’s detected, you will find limited info like file size, date of record, and cam number.
If not found anyone that meets your requirement after searching entirely, please click “Refresh” to begin a new search.
You can preview some files by double-clicking the file name if some files are found.
Step3: Transfer lost videos
You can directly copy and paste on your computer or choose those files that meet your demand, then click the “Recycle Bin” button on the upper right corner to clone all data in it to the local disk as backup timely.
To check whether your DVR has enough space for storage, click “Tools” > “Disk Tools” > “Free Space Info”，it will show free and occupied size with percentage rate without extra calculation. If not comfortable with PC software, you can try another method:
