We had one lady put a tracking system on her vehicle to see if her husband was cheating. Well she found out where he went, but wanted to see who was in the car. So we put a pinhole camera and a data recorder. Turns out he was cheating, with a guy! There are plenty of those available that they use for spy equipment I would search for some of those types of websites and see what's available. Don't know of any offhand as she supplied all the equipment. Mike
