You count on your security cameras to be working day and night. When there is an issue, your building, office, or other faculty is not secured. It can be frustrating to diagnose video loss problems in your system. Here are a few reasons behind losing video in your security cameras.

What Is Video Loss?

Before diagnosing the problem, you need to know the basics of video loss. These issues can come in all different shapes and forms. For example, a CCTV system could lose video in one or all cameras. Some cameras can go black at night, have loose connections, or show a blank screen. Sometimes, the camera will flicker on and off while showing lines on the screen. You might even see a video loss message on the television or video screen. Those examples are all signs of video loss in a security camera.

Common Problems with Security Cameras (and How To Troubleshoot Video Loss)

Generally, video loss of a security camera will come down to a few factors, such as wiring problems, IP address conflict, inefficient camera software, hardware failures, unstable networks, or insufficient power. 

Most people ask, “Why does my security camera say video loss?” or “Why did my security camera go black?” Here are a few common reasons behind those problems and how you can try to fix them in your system. 

Insufficient Power Supply

In most cases, an insufficient power supply is the main reason for video loss on one or all security cameras. Loose cable connections, a faulty PoE injector, or bad power cables can all be the culprit of these problems. 

With these issues, you will want to check everything: cable connectors, power splitters, and wires to exclude all connection issues. Also, switch the ports on the NVR/DVR to ensure the power is enough for the cameras. If you have a PoE switch, try connecting the camera directly to the NVR. Unfortunately, finding the source of your power loss will be a trial-and-error process. 

Power Spikes and Interference

Another reason for video loss is a power spike. This problem can result in all the CCTV cameras having a black screen, sudden video loss, and pictures with a horizontal or vertical line. Power spikes can cause serious damage to the circuit board and other components. 

What causes a sudden power spike?

  • Strong electrical current
  • Mounting camera near metal or conductive surface
  • Lightning strikes

To resolve these issues, consider using a surge protector to keep those cameras and other components safe from a lightning strike. A UPS (Uninterruptible Power Supply) will provide power to all the cameras, mitigating any issues with the system automatically shutting off.

Weak Wi-Fi Connection or Low Bandwidth

Why won’t my security camera connect to my Wi-Fi? A weak video signal often results in video loss. These problems are caused by a weak Wi-Fi connection, low internet bandwidth, or an unstable network connection. Take a few minutes to check the PoE switches and home routers. In some situations, the distance can affect the quality of the video. 

You can troubleshoot the video loss in those analog and IP cameras by connecting the BNC connector or unplugging the PoE switch. It is crucial for those with a wireless security system to check the router and channels for any signal loss. 

IR Cut Filter and Faulty IR Night Vision

If you have a CCTV camera going black at night, it could be a problem with the infrared night vision. You might not have an IR cut filter or functional IR sensor. In some instances, the IR is just not turned on for the camera. 

First, check that the camera settings are set for the IR. You can bring the camera into a low-light area to check if the IR is working. If the camera has a defective IR, you will need to send the camera back for repair or call a professional service to fix the problem. 

Problems with Cables or Wires

Ethernet or BNC cables can have an impact on the functionality of a CCTV camera. Most hardwired surveillance cameras can experience problems with wire-related glitches. Bent or twisted cables are often linked to weak or a complete loss of signals to the cameras. With that in mind, check every inch of the cables and ensure they are connected. Any damaged, cut, or chewed wire must be immediately replaced. 

Hardware & Firmware Problem

Once you’ve ruled out all of the above problems, you might have issues with the firmware or hardware. Updating the firmware could fix the problems, but you should heed a little caution with that. If you are experiencing no video, black screens, and video loss, it might be time to purchase a new security system and cameras.

How to Avoid Video Loss in Your Security Camera

To avoid the issue of video loss, in addition to regular maintenance, here are a few precautions to take:

Check Connections Regularly

Conduct routine and thorough checks of the connections associated with your CCTV and home security cameras. These checks should include the power and network connections, including power cords, power adapters, BNC connectors, Ethernet cable, BNC cable, etc. Ensure the connections are properly attached, in good condition, and functioning. 

Use UPS and Power Surge Protectors

Surge protectors can stop power spikes and surges by hindering the voltage levels from exceeding certain levels by focusing access power into the protector’s ground line.  

A UPS unit or battery backup will make sure all your cameras are powered even in the case of a power outage. So you won’t have to worry about your cameras in the case of a blackout. 

Use Original and Shorter Cables

Your original manufacturer’s cables are professional grade, so these should be used instead of switching them out for other, lower-quality extension cords/cables. These cheaper ones may work for a short time, but they will eventually cause problems in your systems. Also, use shorter BNC or Ethernet cables for your security camera system because they are less susceptible to damage or interference. 

Check Network Configuration

If your security camera uses an IP system, you must check the network configuration regularly. This means checking the subnet mask, IP address, DNS server, default gateway, etc. 

Update Software Regularly

Remember to routinely update the software associated with your system to prevent video loss in your security camera. These updates can fix bugs and vulnerabilities before they are a problem for you. 

Monitor Your System Regularly

To ensure your security camera system is working efficiently, you must monitor its activity regularly. This means checking the video feed, playback, recording, etc. If there are any problems, no matter how small, investigate further and take steps to fix them. This will prevent minor issues from becoming larger ones.
