My wife left her car for 5 minutes and returned, only to find a GPS
stolen. I had a truck window smashed a year or two ago as well.

I would like to find a surveillance system for a car.

Requirements a

1) 12v power supply and low power consumption
2) Unobtrusive look or, better, designed to be hidden
3) Good recording capability to a flash drive
4) NOT BULKY
5) Ability to survive 60 degrees C or so inside a vehicle.

I have looked a little and everything I found is kind of ridiculous,
huge in your face things and huge tape recorders, etc.

Any suggestions?
