What Exactly Causes Video Loss In 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. 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 network, 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.
