    I've had this on my bookmarks for about a year, I'm still interested in putting a 24h surveillance system on my car, any ideas on a good reliable system?

    Regards

    It depends on what you want to accomplish. My goal was to capture anyone who entered the truck. In that case, if you are sure to use low draw equipment, you should be able to leave the vehicle unattended for about 5 days to a week without killing the battery. I ended up not installing it because I couldn't figure out a way to put the alarm on a delay. I can't picture people entering the vehicle with three sirens, including one in the interior, blaring. This negates the purpose of interior surveillance.

    If your goal is to add exterior surveillance, you'll need multiple cameras, 1 or more DVRs (many are 2 or more channels), and likely a second deep cycle battery to avoid killing the car after a day or three. You could trigger the cameras off either motion or an alarm trigger. Take an output from your alarm, run it to a relay, and then use that to switch your DVR and cameras on and off. The downside to this however is that you'll have a few to several second delay as everything comes online.

    If you end up installing something please post some details.

    What I was looking for at the time was 4 cameras, 1 on the back, 1 on the front, and one on each side. It would be for 24h surveillance, to catch something like this in case it happends:

    You could get something like this: http://cgi.ebay.com/Mini-4-Channel-R...item1e5d1201c4 and four cameras. I'd probably use a relay to either turn it on when the alarm is activated or when the motor is off. You could also add an override switch to leave the system on whenever you want such as when you drop the car off for service.

    You'll probably need to add a deep cycle battery to prevent killing the battery.

    On another note, it looks like that Hummer was parked in a handicap spot. In the second shot, the parking space below it appears to be blue. lol

    How much do you think a system like this would cost, including all material needed.


    Thanks

    If you look at the previous pages, I've outlined a system that works perfect.

    A multi-channel hard drive based DVR will most likely NOT work for 24/7 use because the power consumption is too high. You can run it off a big deep cycle battery, but you also have to keep in mind that lead acid batteries take time to charge...so unless you drive for hours and hours each day, you probably wont be able to keep the deep cycle battery topped up.

    he can combine LiPo + Pb battery and that will solve charge tyme problem but will increase complexity

    I have something on my desk now that might be useful its 4ch dvr running of single LiPo it works about 3 hours of 720mA battery... I have 5200mA battery aybe this will work in the car too
