Ally1321 0 Posted October 9, 2020 Hi, I’m looking for some help with PTZ camera. The camera intermittently flickers and flashes. I have it directly hooked up using RS485 to a power distribution box. I also have have a ground loop isolator on the camera. I have two of these same (PTZ) cameras, this is the only one that flickers with lines, but both will cut the picture if I move the camera. I am assuming it has something to do with the power? I have a 16ch DVR but only 9 cameras hooked up. Only 2 are PTZ’s. Any suggestions would be greatly appreciated.
