We have compiled a list of the most likely reasons why you might be experiencing video signal loss on your CCTV security cameras and systems and DVR camera systems. We also give you tips on where to look to resolve these issues quickly. and efficiently and allow you to be operational.
What does video loss look like?
Sometimes a CCTV system loses video feeds on one or more cameras, a camera loses a connection, goes black at night, or gets no video with a camera showing a black screen. a screen and monitor aligned, or the DVR is not receiving any image or signal from the camera. As you can see, there are many potential problems that can arise in the operation of your system.
Let's take a look at the main offenders.
Reason #1: Insufficient power
Let's be clear. This is different from a power outage. This is a situation where there is not enough power, resulting in video signal loss, camera going black, or video flashing. Here are some common reasons for insufficient power supply:
Loose cable connections
PoE switch or PoE injector not working
Cable is too long or one cable powers too many cameras at once
Defective power cables (old, damaged, degraded)
What is the solution?
Check all power connections, power splitters, and cable connectors to rule out connection issues
Switch ports to make sure the DVR/NVR port is powering the cameras
Connect the cameras directly to the NVR instead of via PoE in case the PoE switch might supply insufficient power. This is because PTZ cameras and IR cameras require more electricity.
Try to use shorter BNC or Ethernet cables to power the cameras and avoid using poor quality extension cords or extension cords.
If you are using battery powered cameras, make sure the battery is not dead or the solar charger is blocked.
Reason #2: Power Spike and Interference
A power spike can be a terrible problem for a system. It can cause sudden video loss, completely black screens or vertical lines, and serious damage to camera circuit boards or other components. how it can happen:
Mounting the cameras on a metal/conductive surface
lightning
Electrical current interference from nearby electrical equipment
What is the solution?
Use electrical and lightning surge protectors to protect your equipment
UPS (uninterruptible power supply) units will protect your equipment from power failures
Use a block of wood in between if there is no non-metallic surface to mount your cameras
Reason #3: Weak Wi-Fi Connection or Low Bandwidth
Video loss or weak video signal on security cameras on a wireless network segment can be caused by unstable network connections, weak Wi-Fi connection or low Internet bandwidth. Here are some reasons:
The camera(s) are too far from the home router
There are too many physical barriers between your camera and the router
WiFi signal interruption and interference
What is the solution?
Move your cameras closer to the router if possible (or your router closer to the cameras if not)
Choose the correct channel (some routers can emit 2.4 and 5 GHz signals)
Avoid physical barriers (walls, trees, etc.)
Use a WiFi range extender)
Reconnect the BNC connector and unplug the PoE switch to resolve video loss issues on analog and IP PoE cameras
Cameras on a wireless network segment, check the network and possible network interruption
For cellular security cameras, make sure the SIM card is properly inserted and data is not full.
Reason #4: Faulty IR Night Vision
One of the main reasons many security cameras are installed is to keep an eye on things at night when the business is closed and unoccupied. The building is dark inside and out and the need of IR night vision cameras is essential. So not having a working IR night vision is a big problem. Here are some of the problems:
You have not installed an IR camera
Defective infrared sensor
I forgot to activate the IR
What is the solution?
Check your NVR/DVR settings to make sure IR is enabled
Use external IR illuminators or spotlight
Reason #5: Signal type and compatibility
If your DVR or NVR shows video loss or no video, it may be because your system is not able to decode video stream from different brands of cameras. What may be the problem?
Cameras and NVR/DVR are not compatible
Cameras with a 5MP or 4MP are not compatible with NVRs and DVRs that decode 1080p cameras
Some DVRs can't decode old CCTV cameras
What is the solution?
Consult a local technician
Use the same brand of DVR/NVR as your cameras
Reason #6: Wiring or wire issues
BNC cables or Ethernet network cables, to some extent, could impact the functionality of security cameras. This is especially true for analog CCTV cameras, which could experience a greater risk of video loss or loss of signal than PoE cameras. Some causes may be:
Wired cameras (analog, PoE) may have twisted or bent cables
What is the solution?
Check every inch of wiring - no frayed, cut, bent, chewed wires
If necessary, try replacing the wiring
Reason #7: Hardware and firmware issue
If you've ruled out everything else but still haven't fixed the problem, your NVR/DVR or CCTV cameras may be in poor condition. Some of these potential causes may be:
Old or buggy firmware
Firmware needs an update
What is the solution?
Update your firmware (WARNING: Updating firmware without a thorough understanding of updating can create more problems than it solves!)
