Camera came in on time and looked great at first. Then the unit would only show a grainy picture....then would work. This went back and forth for many days. Then I pulled the camera back out and discovered that where the wire comes out the back of the camera was loose so I screwed it back in and it worked. Since then the camera has gone out and is no longer working. Did not return since the camera is so cheap it would be more of a hassle and waste of my time for the value. Very dissappointed.
