I've been looking for a DVR solution for awhile. A few of my requirements:

1) Has to be able to record from multiple inputs simultaneously
2) Has to be able to record even if the car isn't on (security purposes)
3) Has to be able to record for extended periods of time
4) CCD cameras, not CMOS
5) Needs to look rather OEMish, (covert, not overt)


Stumbled across this today:

Highlights: 2 adj. front-facing Sony CCD (not CMOS!) color cameras, multi-input recording (w/audio!) and the ability to add 3 add'l cameras.

Picked up one for today. Should be excellent for general use (security when parking in parking lots/parking garages, that kind of thing). The eventual plan is to pick up the other add'l cameras, and have one for rearview use, the other aimed inside the truck in an obscure location to record the cabin in event there's a break-in (the unit can be set for motion activation, as well).

Edit: found this pretty clean install on a Mazda3 w/actual camera footage:
