A security camera is one of the most useful devices these days as it helps to monitor activity around and inside houses and commercial spaces.
However sometimes the live feed may flicker and this may prevent us from seeing the coverage properly.
If you are experiencing something like this then it is important to know the reason and then solve the problem. The following are some of the causes and solutions for security camera image flickering
Check the video input to the monitor?
1.CAUSE: The first thing that you will need to check is whether the video input to the monitor a loop through with a video output to drive for example video tape recorder.
SOLUTION: Assume that the video output is present, then check whether it is terminated with a 75 ohm load. You might be overdriving that video circuits of the monitor with a lot of signal and the flickering may be caused due to the monitor’s AGC circuits.
Disconnect the video input to the monitor
CAUSE: Another thing that you need to check is whether the image still flickers on disconnecting the video input to the monitor. If the flickering is still observed then the problem may be because of the monitor.
SOLUTION: In this case, you can try changing the monitor and then checking the issue.
Disconnecting and try the coax at the camera output
CAUSE: Another thing you can do to find out the cause of the security camera image flickering is to disconnect the coax at the camera output. Check if the flickering still continues.
SOLUTION: If yes, then check the electrical outlet of the monitor. This is because of the fact that the outlet may have an ungrounded neutral and as a result, your cable and the monitor may not be grounded. This leads to compromising of the shield ground and you picking up stray radiation.
Check the environment weather condition ?
CAUSE: Another cause for security camera image flickering could be bad weather and hence bad reception. If the image on the monitor is flickering, then check whether the weather is clear or not. If not, then this could be a possible reason for the flickering.
SOLUTION: Wait for the weather to become normal again and then check the image again.
