Anyone know any small and not to over priced motion activated cameras that I can attach to the car.

I need something that isn't visible but will activate when someone tries to walk next to the car. I also need about 3-4 cameras. One for each side mirror and something for the front and back.

My entire life, I always had someone messing with my mom's car or dad's car. I know who it is but I have no evidence to point my fingers at him. Please help me out in looking for a small affordable camera system for the car.

I have been looking around and can only find the ones that show the front and back.

Thanks
