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."

    "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."

    Not sure I understand, this means that after you press "record", the DVR travels three to five minutes backward in time and catches you in the loo a few minutes prior? Surely the video would spool to disk 3 to 5 minutes after it was recorded. Maybe I can use one of these after I get pulled over for speeding to travel back in time and brake in advance...

      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.

      Um, it sounds like the *central* tape will start from 3-5 minutes before the cop "actually" turns recording on -- just so they make sure they get a bit more than just what the cop feels like needs to be seen.

      I don't really think this is a keep-the-cop-honest feature, because there are much better ways to go about it than that. I think it's just to help establish the context in which the cop used the recorder.

      It means that video is continuously recorded, with the oldest video overwritten, and that when you press "record", you don't really start recording. Instead, you just mark a spot in the video stream, and the software takes the time three (or five) minutes previously as the "start" time. Those video bits wouldn't then get recycled.

      Makes sense. You're only going to hit "record" after figuring out something interesting is going on, and you can't hit the button immediately.

      Why not put in a HDD big enough for a WHOLE shift? Then make the drives external and changeable, at the start of a shift the cops insert the drive. It records the whole shift (including all radio traffic). At the end of the shift the WHOLE thing is stored somewhere. This could be seen as a bit of envasion of privacy, but could also protect them in court. There's no way that could really "edit" the tape with it showing.

      It would be pretty damn hard to 'edit in' the person striking first, but there is an easier way. The cops can just carry a bulk tape eraser and a power inverter for the cig lighter, then wipe out the hard drive after they get midevil on someone's ass. Or a 5# speaker magnet. That should cook the hard drive if used properly. Then just say "I dunno what happened to the system, it should be there to prove I didn't do anything".

      Paranoid. :)

      First off, if you do the math, it's about 700 megs per hour of footage, as opposed the 13 gig it'd take to losslessly compress it. In order to edit somebody in, the video'd have to be recompressed, and that would be noticable upon analysis.

      Secondly, it is *very* hard to digitally add/replace somebody in a video. Professional studios have difficulty doing thing, it's inconcievable that the police could cover something up that way. They wouldn't have the talent on their own and the money needed to do it enough to not raise eyebrows would raise eyebrows.

      It'd actually be easier to pull that off with plain old VHS camcorders. You can duplicate them without too much quality loss. (Or at least noticable.) The video's lower res and fuzzier so it'd be easy to mask effects. The higher the resolution and color accuracy of video, the harder it is to satisfactorally match it.

      I wouldn't worry.

    A motorcycle is a rather space-constrained and high-vibration environment, and a conventional tape-based system simply wouldn't cut it. A company here in Wheat Ridge, CO has done several installations for the Colorado State Patrol's Harleys. They also borrowed a BMW R1150RTP from us and did a demo installation on it.

    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.

    Another thing that came to mind - this device could be the equivalent of a 'black box' on an airplane - you could have BlueTooth enabled guns / batons, health montoring devices in the uniform... this could bring a whole new level of evidence to bear in a Rodney-King style event. What if the police could show from a EKG strip that the cop really was scared for his life? Interesting stuff...

    Basically we had a system hooked up to a digital camera that recorded to temporary files. If something tripped off a sensor, it was configured to save the previous X moments of video rather than dumping the cache file. Really, it makes sense, since for spontaneous events you really want what happened to get your attention, not necessarily what happens afterwards (or both).

    As for the duration of recording... wouldn't it be nice if the recordings weren't viewable by the officers on duty. That way, it could be juggled to a little over 5 minutes (or a lot over), and anyone trying to "wait out" before pressing record would be S.O.L.

  16. Cool but very dangerous. by OwnerOfWhinyCat · · Score: 4, Insightful

    Bad assumptions abound here. Yes, this could make citizens safer from police. And since "Police Abuse of Power" is a popular meme it may seem like it's all daisies. First off the article doesn't go into nearly the depth needed to establish authentication. For instance: The recorder authenticates all the video to prevent changes, and it will have a checkout system to keep track of which officers have checked out which hard drives.

    This could mean the officer get's handed a clipboard and "signs out" a drive, like he does a gun or any other piece of equipment. For evidence that can be so damaging (to both victim and jerk (whichever they may be)) the standard must come up to a whole new level. Anything less than outstandingly modern security will allow the tired mystery novel scenario to occur:

    Officer A switches tivos with officer B; Officer A checks out drive 1 while signing for drive 2. Officer B checks out drive 2 while signing for drive 1. Officer A goes out to do something bad. Officer B drives a rush our traffic route so there are no tickets to hand out. That night they check in their drives, but Officer A has wiped his. Later Officer A is accused of a crime and has video to prove that he was somewhere else at the time. The fact that Officer B's drive crashed that day is not compelling evidence of anything.

    The device that checks out the hard drive should be a black box digital time clock that puts it's own signature in the data of the drive. The vending company should make the public keys available to verify the signature, but keep the private keys out of the reach of law enforcement altogether. The officer that checks out a drive should type his pass-phrase into the checkout terminal so that it can generate a second signature that cannot be replicated without the pass-phrase. The Tivo-like computer should, in addition to other features, keep a running log of which hard drives (by signature) have been inserted into it and when, and these logs (up to the last say 100 insertions) should be included and signed on each new hard drive that goes into the Tivo. So any hard disk mucking about would be distributed over all the hard disks in the pool, and they would therefore have to destroy them all to successfully cover this stuff up. With the addition of signed GPS location/timestamps swapping/editing could be pretty tough especially if the tivo device derived it's signature from an unremovable factory issued SIM.

    It's worth noting that I've never seen an episode of "Cops: A night of police screw ups."

He finally left...I put the gun back, and told my folks.
