Been looking and researching for a while and not getting much for a full time rear view camera. I finally bought the Rear View Safety 3rd brake light with mirror replacement monitor. The camera seems well built and fit well, but is totally useless for full time rear view, and not too great at back up. It's on a high top, and if aimed where I can see the trailer hitch ball, (and only the ball), I get about 6 or 8 feet behind me. If I aim it all the way up I get 15 or 18 feet. I like the monitor, and the fact that it has a separate input controller for 3 cameras, I can connect 3 cams or 2 cams and a DVR and only run one cable through the headliner to windshield. I've searched the forums here, and elsewhere, not finding much on full time. Plenty on backup cameras, but those are cheap and plentiful. A full time rear view camera should be 60 to 90 degree. I'm finding 130 to 170 degree. Note that a typical windshield mount mirror gives around a 30 degree view. Anything over 90 degree makes judging distance nearly impossible. I can find plenty of cameras suitable for full time in AU, NZ and UK, but it seems that in America, the only things available are very wide angle. I'm not sure about importing one as most seem to be PAL, and I'm not sure they will display on a normal US monitor.
