Have anyone purchased this before? (also called Car DVR)

Amazon.com: Itronics ITB-70G Car Black Box Dash Camera Video and Audio Recorder with GPS Record: Electronics

Amazon.com: Smart Black Box Drive Recorder: Electronics

I want it to operate when the car is parked... (I go to NYC a lot, and many things have happened when the car is parked....) Maybe for that, not at 15 frames per sec but like 1 fps or even 0.2 fps....

I can find these from only Amazon.com... is there any other place to get this?
