back up cam x 5 dvr

is there 12volt equipment available to record 5 video inputs simoultaneously that also includes one audio input? similar to survelance systems for commecial/residential situations but "in-car" thanks

4 video and 1 audio  http://www.dvr.com/product.php?productid=16214

I cant belive that unit is 20 pounds! that site has some intresting gadgets. Im trying to cover 360deg view plus interior, need 5 inputs. I havnt found a unit made specifically for mobile use yet. Im trying to avoid having to use an inverter. thanks

Are you sure about the interior as well? I have a few interiors, but they do the outside as well. Problem with interior is do you want across to each side (ie, window & door entry) or up from the floor (as they look down to hotwire or pull your audio) etc? You may have thought out the system to suit whatever application. But I often find that people overlook: - the resolution required to ID faces (legally); - lighting required when dark; - power required with constant operation; - the hours required for playback without "detection" software; - concealment of said device (and maybe its swappable storage) once the cameras have been spotted. (Note: Explosion & heat-proof enclosures are recommended!) Movement triggered recording solves some of the above. Whilst image movement detection is now cheap and incorporated on some cameras, its "quality" expense else tricky setup (moving trees, clouds, etc) still detracts. Microwave detectors are still probably the best economic solution. But IR/Doppler or image methods provide the directivity that uWave doesn't. Just in case the above are new considerations. Apologies otherwise for wasted space and notifications.

intresting info OS! actually Im not working on a survelance system but from what Im gathering some of that equipment may work. Im trying to find a system to constantly record 5 inputs while mobile (driving) thanks
