Catch your accident "event" on video?

[aussiblue]

Interesting idea from Deals Direct:

An Event Recorder is a device that records video for creating a record of accidents or driver and vehicle performance. It's automatically activated by an event that is triggered by the built-in 3-axis G sensor that responds to a sudden change in wheel speed. It starts recording to an SD card and can also be triggered manually with the remote control if required. No installation - it simply mounts onto the windscreen like a GPS unit. Having a recording of events will protect your side of the story in the event of an accident or other disputed circumstance. Depending on the size of the SD card, you can capture several hours of video. Ideal for fleet operators, taxis, hire cars or the everyday person who spends a lot of time on the road. SD card not included.

Stay entertained and up-to-date with the latest in Electronics trends. You can find TVs, DVD Players and even Digital Cameras at unbeatable prices. Love a bargain!
