I also am wondering if you have used this camera in the daylight? The fact that you don't know if it's B&W or Color, has me wondering?
At night, do those little red lights light up? Does the monitor at the dash appear to work, or is there a blown fuse or something? Could be a broken cable to the camera too?
The fact that it's got the IR lights tells me that you should have an image at night, though it will appear to be similar to a B&W image (though may be greenish too).
You need to see if you have an image during the day, and if the monitor even works.
Once you know that, then you can let us know, and maybe we can help troubleshoot it with you. Lots of very smart folks on here!
Good luck
