Some people have said that pioneer's backup camera isn't that great. Is this true, and if so do people have any recommendations for good cameras to use instead?

I like my Pioneer cam

I really can't comment about the Pioneer camera, except that I think it's over priced. I'm using an Accele WPLC296R bullet camera. It's a 21 mm diameter, color, reverse image camera. I purchased it for $180. Day time images are great, night time images are ok, but could use some improvement.
