Car Camera Recorder Pro : Brickhouse Security

Thankfully this DVR-equipped rearview mirror isn't meant to let you watch a few scenes of your favorite shows while crawling in traffic. The Car Camera Recorder Pro turns on automatically when you start your car, and shuts down when you stop the engine. It attaches to any existing rearview mirror, and plugs into a standard car lighter.

The company claims the device reduces blind spots, but the main advantage is the DVR. Get in an accident that's not your fault? The device records the event, storing the video on an SD card, and preventing you from being subjected to higher insurance premiums because someone else doesn't know how to drive.
