The second one I bought was just because it was cheap, This one is also a B/W CCD camera (
PC302XS) but it's small, it also has 420 lines of resolution, and 0.01 Lux according to the sheet that came with it. This one was only $18.00 and this one works. I tested this one out through the video Baluns and was pretty surprised with the results. The video is crisp and the quality is nice, (this might make a good starter camera for the price) the only downside for some people might be that it has BNC connector not RCA, but they do make adaptors. This one will probably go on my Mule Rov when I finish it this year.
