Thinking it is possible because the camera IR sensor is too sensitive. When your shop is a little dark, then IR turns on and screen image's brightness increases. After IR is on , when lighting is enough to trigger the IR sensor to shut off the IR, then brightness decreases.

I'm runing cat5e with baluns, but no more than 120ft of cables, and power is shared from one 12V 5A PSU. When 2 or more cameras, on the individual power supply, there's no picture scrolling bars and other interferences.. what to do? You mentioned"Power is shared from one 12V5A PSU" Then ,saying"When 2 or more cameras, on the individual power supply, there's no picture scrolling bars and other interferences." What kind of power supply are you using actually?
