DVRs for Cop Cars 368

Posted by michael from the season-pass dept.
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.

        After reading everyone's suggestions on how a policeman who did something questionable might want to 'game the system'; i.e., get the disc to record over the problem moments...

        I wonder what will happen when they put REALLY big drives in these things that record the whole shift. More police cars unfortunately running off the road and exploding in flames, I suppose (with the drivers miraculously saved.)

        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...

        • The outcome I really hope to see is tied to the "record when the flashers are turned on". Currently, cops who get tired of obeying all of those tedious traffic laws they ticket everyone else for just flash the lights, get past the blockage, then turn off the lights and go on with their lives. Logging each and every use of emergency signals will cut down this abuse - if they have to justify why they hit the shiny red button, they will probably stop hitting it unless it really is needed.

        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.

      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.

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.

      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.

With the rapid advance of hard drives (there was an article here saying they improved 10,000-fold over the last decade or so, IIRC), and the opposite advances in video compression (DIVX/XVID et al), there should be no reason not to record everything.

    Then it will be mighty suspicious if a cop's video "suddenly breaks." Perhaps two independent recorders would be called for?

    My wife was visiting a friend in Brazil recently, and they were staying at a hotel. Her friend was accosted one night by a security guard who had red eyes and was acting funny (likely he smoked pot), and hit on her and put his arm against the wall, blocking her path. He followed her up to her room.

    She has a friend who is a cop, and he was with her that night just prior to dropping her off; he has the receipt from the restaurant they ate at, marking the exact time they left, and they went directly to the hotel. Strangely, ALL VIDEO stopped working that night.

    Which is actually better for my wife's friend: now the hotel has broken two laws, a sexual harassment as well as a federal law of destroying evidence. I hope she wins.

    We're entering the strage era of having no privacy outside the home (and little privacy inside, as cops use thermal imaging to detect tomato growers). If we're going to record, I think it best that we record everything, especially all government employees -- including politicians, police, and military. As others have said, these recordings will reduce police corruption.

    And if we recorded politicians 24/7, we'd end the era of "big oil" deals, and RIAA/MPAA-mandated legislation, and all sorts of crap that goes on in back rooms that nobody ever hears about.

    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."

    Censoring the things they don't want seen is already the norm, and it will continue to be unless we legislate it otherwise.

    Now, hook a wireless transmitter up to that videocam and let the reality-police shows abound! Think of the possibilities. Stream the video from selected cruisers live on the 'net. You get a UI to select the cruiser you wish to view, and voila! you are right there in the action.

    That would be my biggest question, since the digital format is an order of magnitude easier to seamlessly edit than analog media.

    The number of illegal and dangerous manouevres I see every week is significant, and I doubt that this is specific to where I live. I was pondering the idea of having a DVR like this and passing on recordings to the police (and volunteering as a witness to attest to the locations, times and accuracy of the recordings). It isn't going to happen any time soon, especially given that I'm going around on a bike not in a car, but maybe some time in the future it will be practical to fit DVRs to vehicles. The mere fact that they are commonplace would, I hope, act as a deterrent against the sort of crappy driving that people mostly get away with now. (Bad cyclists are another matter; without registration plates it's going to be hard to identify them. They're mostly a danger to themselves, though.)
