He has done what you are asking. He also responded to someone elese who did the same thing, but he "skinned the cat a different way".
Read through those posts. Very interesting reading.

Naturally you would want a mobile 4-channel DVR. I would use four color board or bullet cameras, something small that doesn't draw too much attention when parked.
Having two cameras front and two rear allows you to have either a wide and telephoto each, or point each pair slightly to either side and "add" the views horizontally.
I tried the latter method, 3.8mm lens giving about 154 degrees total both front and rear, a really panoramic view but I couldn't read license plates. However, stopped at a pedestrian crosswalk or traffic light I could see both left and right curbs.
Think about what you are trying to achieve and pick the method to suit. I placed a microphone near the drivers seat so that I could simply recite a license plate if needed rather than have to read it off the video.
The only problem with recording sound in my case is that my recordings mostly consisted of me talking to myself or cursing at other drivers.

There are several mobile DVRs available out there. There are also PC104 DVR kits which you can use to build these.

For those of you with law enforcement problems I have a suggestion on a covert camera that would be great, but I do not want to post this suggestion in the "open". Post here then I will PM you with the suggestion.
It give a great view of the driver's door. Some law enforcment approach from the passenger's side at first, and you have to prepare for that as well.
Those in the biz are probably familiar with it.

Does this sound like someone who has experienced these situations, and all along I thought He was a law abiding honest citizen. :shock:

Darn it RickA you know me too well!
No, I just did not want to revel publically what may be used by narcotics, and other "stings" in video surveillance.
