I hope someone can help. I have set up (still tweaking it) my first day/night color camera and I am experiencing color lines in the video at night. If I turn the saturation level down to the point where the video is b/w the lines go away. I am using a KT&C KPC-N600H1 camera with a Geovision GV-800 DVR card. It this normal? The picture is flawless during the day. Thanks in advance.
