I purchased multiple V3 cameras and V3 pan cameras and they all seem to have a static noise. Each camera appears to have a different type of static noise including a TV type static, a whistling sound, etc. Some of the camera have static sound that comes and goes however have not been able to fix it.
I tried moving the cameras around the home and different outlets without success.
The microphone itself is not sensitive enough to pick up voices well either and the static makes it even harder to hear anything on them. I ordered a few Pro 2K cameras to see if they have the same issue but this problem makes the camera almost unusable for security.
