Video loss is the most prevalent CCTV security system problem.
Your security cameras (IP cameras or analogue cameras) suddenly stop operating, a video loss message appears on the monitor or TV screen, or your cameras' pictures are completely blacked-out out of nowhere.
So, what causes video loss in security cameras?
In general, issues related to "loss of video" on CCTV cameras or the DVR/NVR are caused by a variety of issues: failed power supply, faults with wiring, network unstable, hardware failures such as cameras, monitors or NVR/DVR, failed camera software and conflicts with the IP.
Read our guide to learn more about what causes video loss in CCTV cameras and how to fix the video signal.
What is Video Loss on Security Cameras?
The loss of video security cameras occurs in a variety of forms.
For example, if one or all of a CCTV system's cameras lose video signal, the entire system experiences the loss of video at the same time.
A CCTV camera's connection gets loose, the screen blacks out at night, or there is no video when a surveillance camera displays a black screen.
The video might flicker on and off; lines may be seen on the screen and monitor. There may also be difficulties with the H.264 DVR: no image, camera failed, faulty IR night vision, etc.
Why Does Camera Video Loss Happen?
Generally, the problem of "video signal loss" on CCTV cameras or DVR/NVR systems is due to a number of reasons:
Common Reasons for Video Loss:
- Failed Power Supply
- Network Connection Unstable
- Wiring Faults
- Hardware Failures
- Camera Software Error
- IP Address Conflicts
Insufficient Power Supply
When your security camera's power supply drops out, it is frequently the reason for video loss on one or more of the cameras, CCTV loss at night, signal loss on the screen, camera blackout, or camcorder fault.
The first thing you should check is if the problem is with a single camera or multiple cameras. If it's a single camera, then most likely, the power supply to that particular camera has failed or there is insufficient power.
If this is the case, you will need to replace the power adapter for that camera.
However, if your security system experiences video loss on all cameras at the same time, then the problem is probably with the power supply box that powers all the cameras.
In this case, you will need to check all the connections and make sure they are tight. You may also need to replace the power supply box.
Unstable Network Connection
If your security system is IP-based, then an unstable network connection can cause video loss on one or more cameras. Most IP-based security cameras use a wired Ethernet connection.
If the connection between the security camera system and the network is not stable, it can cause video loss.
To fix this, you will need to check the Ethernet cable and make sure it is properly connected to the camera and the network. If the problem persists, you may need to replace the Ethernet cable.
Wiring Faults
If your security cameras are hardwired, then loose or faulty wiring can cause video loss.
To fix this, you will need to check all the wiring and make sure they are properly connected. You may also need to replace the wiring.
Hardware Failures
Camera failures are one of the most common reasons for video loss. If your camera is not working properly, it can cause video loss. To fix this, you will need to replace the camera.
Another hardware failure that can cause video loss is a monitor failure. If your monitor is not working properly, it can cause video loss. To fix this, you will need to replace the monitor.
Inefficient Camera Software
If your security cameras are using inefficient software, it can cause video loss. To fix this, you will need to update the camera's software.
IP Address Conflicts
If your security cameras are using the same IP address as another device on your network, it can cause video loss. To fix this, you will need to change the IP address of the camera.
These are some of the most common reasons for video loss in security cameras. If you are experiencing video loss, check for these problems first.
How to Fix Video Loss Issues?
Now that you know the reasons for video loss, let's look at how to fix them.
Fixing Power Supply Issues

Avoiding Video Loss on CCTV & Security Cameras
Video loss can occur in a variety of ways and under various circumstances, such as;
- Loss of video on all cameras
- one CCTV camera's video goes black screen at night
- no CCTV video signal from the camera
- an image with a black screen on the camera
- cameras not recording anymore
- cameras turning off and on
- failing cameras
To avoid such problems in the first place, it's always a good idea to check your security system on a regular basis and take the appropriate countermeasures to prevent video loss on CCTV cameras and home security cameras.
Check All Possible Connections Regularly
You should do a complete inspection of all power and network connections, such as the power adapter, power cord, BNC connector, Ethernet cable, BNC cable, and others on a regular basis to ensure that they are firmly connected and working correctly.
