Just ordered another USB camera, wide angle view to put in the rear and a wireless mic.
I've been driving very legally the past few weeks and getting video from the front of the car, but I need one at the rear too.
I also ordered a P3 1.2Ghz processor with a 133Mhz bus. Right now I have a celeron 533(66mhz bus) and it worked great with everything, but the cameras require a lot of CPU overhead. I need a faster processor to keep from video frames being dropped, keep the video smooth and to keep from overrunning my DAQ's buffer.
