When I was on the road to Vegas for CES, I wished I had some sort of video recorder so I could just speak my mind and write about it later. It would have definitely saved me some time and would have made the trip a lot less boring. On a somewhat related note, Nikkai has created the In Car Journey Recorder, which is the inverse of my idea.
Yes, the In-Car Journey Recorder is designed to affix to the windshield to record the road ahead, not the driver. It uses a 1.3M CMOS image sensor, which can record video footage for your insurance or lawyer in case of an accident. Now you have proof that it really wasn’t your fault in a collision case, when it’s your word against someone else.
The In-Car Journey Recorder records to an SD card for up to 2GB capacity, which is good for up to 18 hours worth of video footage. It can capture intervals between 2-3 seconds and 3 minutes.
As for power, it is powered by two AAA batteries for four hours of continuous use. It is also capable of being powered by a DC 12V charger. You should be able to purchase the Nikkai In-Car SD Journey Recorder at the Maplin site for about £39.99.
