DVRs for Cop Cars
AEton writes "News.com is reporting that IBM is developing digital video recorders for cop cars. The systems involve a digital video camera and reusable hard drives which police officers will take with them on their shifts; centralized servers with up to 3.5 TB of storage will hold recordings. The cameras continuously record and cache old video in a "Tivo-like" fashion; tapes will start from three to five minutes before the cop turned on the recorder. Unbiased, high-quality recording could have a compelling social effect; and at the very least, we're headed for HDTV Cops."
An interesting concept, but no.. what they're pointing out is that the video would be run ALL THE TIME, and discarded after 5 minutes. When the cop presses "record" the machine would save the video from 5 minutes before the record button was pressed in addition to all the current video until the "stop recording" command is sent.
The system works just as described: The system is always recording to a programmable-length buffer; once the officer cuts his disco lights on, the buffer becomes a permanent file and current events are appended to it.
I didn't ask any questions about how easy it was to erase files off the system, but I remember seeing a keypad on the unit and the guy I brought the bike to did enter a code before he got into any of the menus. It would be easy enough give those codes to the station chiefs, but not the patrol officers.
This is not my sandwich.
