If you’re sick of seeing more of your elbows than the traffic behind you when you’re riding around on your vintage Lambretta or brand new 999R, or if you’re just the kind of gadget-head who wants the latest tech on your ride, you might try the MotoCam. It’s a rear-view video system designed for motorcycles, with camera and 2.5″ to 4″ TFT screen. The unit comes with mounting hardware and is fully waterproofed. The camera is “high-resolution” and “side-angle viewing” for good visibility. An optional infrared camera is available for riding at night, with the images displayed in b/w. Prices range from $300 for the basic camera system without display (?) to $650 for the chromed 4″ TFT with IR camera. Units are also available for RVs and boats. Of course, if you want to DIY you could always get a TFT and an x-10 camera…
Update: I just spoke to the mfr, who gave me some more details. First, the TFT is not transflective, but is viewable in daylight though best with the sun shield (inlcuded). Second, the camera-only module is designed for recording rides on a camcorder. Third, the camera has a 75 degree viewing angle, which is significantly better than any x-10 camera you can get. Finally, the IR camera is both a normal color camera and an IR cam, and switched automatically when in low-light conditions.
