I have 3 cameras, front, rear and driver. A video processor turns it into dual picture-in-picture so there’s no post processing necessary. I still find lots of ways to screw video up, but that’s my fault.
One of my objectives was for the system to be infantry simple. I couldn’t be hitting a bunch of buttons and hoping that I got it all right as I headed for the grid. Once I throw a power switch on the dash in the morning, I have to hit one button on the video processor and that’s it. When I power the system back up the next day, I hit that one button again.
These little lipstick cameras come with little bases. If you bend the base a little bit you can use some hose clamps to fasten them to your cage. I used some loctite in the camera base pivot mechanism to help toughen it up against shock and vibration.
Video cameras. You want 520 (or better) lines of resolution and a 1/3" CCD for your forward camera. The driver and rear cameras can be 420 line and 1/4’ CCD. Don’t screw with any zoom features or anything like that. Simple cameras will be more durable.
Good camera for front view. >520 line and 1/3" CCD. $120

$40 video processor. This may be the same one that I have. It will take 3 camera inputs and give you dual picture in picture.

My only expensive item was a ChaseCam PVR. I decided on it because Traqmate can tell it to start & stop. A non Traqmate user would have all sorts of possibilities for recording the video. Only one video line comes out of the video processor. There’s 100’s of solid state devices on Ebay that will record that for you. Just be sure to get one that will output a common video format like .wma or mp4. Don’t bother with HiDef, those files end up too big. Leave that to SpeedTV.
That’s 3 cameras and a video processor for less than what you’d pay for 1 Chasecam camera.
