I had that problem on an
Amcrest 2MP analog 2MP camera. It was installed with
Cat5e and Baluns on the ends to convert it to coaxial BNC connectors.
The cable run had no choice but to run across electrical conduits (120V) and even parallel to Conduit for several feet.
There some kind of image distortion where you could see that light poles had that same effect. they had a slight double image like that.
When I upgraded that cable to an IP Camera, the issue went away.
So i moved that camera to another location and now it looks fine.
