Interference?

Recommended Posts

Anyone have an idea what causes horizontal lines in low light? These Swann Pro 540 cameras have a decent picture in daylight. When switching to B&W, they are pretty clear until it gets dark, then these lines begin on three out of the four cameras.

I bet the lines clear up if you add a bit of white light to the scene. Looks to me like the chip in the camera is trying so hard to get a passable picture that the "Pro" camera is almost screaming. I will say that I've seen cheap-ish IR cams function in the dark with better picture quality than those shots though.

Thanks for all the replies. I have turned on lights, and the picture clears up, but I thought that's what the led's for for--to enable the cameras to see in the dark. I guess I got what I paid for. The system was on sale at Sam's. They just might get it back.
