    AIO Carputer / Black Box Recorder what options do I have

    Pretty much having a hard time finding a DVR that does what I want
    has features I want , but i am not wanting something dash mountable / built in camera's
    ( I want to use my own camera's and where i want them )

    pretty much this is my setup

    2x camera's in Left Mirror facing FRNT / Rear
    2x camera's in Right Mirror facing FRNT / Rear
    Bonnet cam
    Spoiler cam

    Running through a 8 cam multiplexer

    Reversing / using R/L indicators changes the camera config

    I also have Visor Monitors / Rear View Mirror monitor and double DIN touch screen that ran the mp3 player ..

    now what i am wanting to do is record all camera's in h.264 format along with speed / GPS / time data

    and if possible broad case GPS location ( my android phone does this so it shouldn't be to hard )

    I am thinking of building PC to sit under passenger front seat .. or Glove box as i am guessing i will have to hunt down an pci-e card for recording the camera's unless their is some usb thing out their ?

    ( car is Tripple Battery also .. and has a solar trickle charger ( only charges the 3rd Deep cycle battery which is the fail safe for the 2nd dry cell AUX battery that can also be used as the crank battery if needed 1st wet cell battery gets charged up via Alternator first )

    o did I mention I wanted motion sensor based recording when when the car is turned off ( i know its possible but not having much luck finding the software

    Need NAV ( Augmented if possible ... )
    Need DVR ( complete Black Box )
    Need Multimedia Player
    Need OBD 2 Tools ( also wanting to log all engine data alongside video / GPS location )

    I am also wanting to change camera's to tuneable ones that I can adjust whilst driving but ,,, I can live with out I was hoping by now some motorized ones would be around

    you reminded me i need to look something up for work..

    but anyways, some of it is a little iffy..

    1.the all-in-one cameras are going to be a better quality then 90% of component parts:

    the all-on-ones allow the engineers to control all aspects, and allow the recorder portion to talk directly to the video processor-- meaning they can more easily record in higher pixel-count formats.

    separate components need to rely on standards already in place-- in most cases this means that the cameras and dvr's need to use the composite video standard-- which is about 480 vertical lines of resolution(i want to say most images have about 500-600 horizontal lines). these images are not high quality. they are decent, but not good enough to see license plates, or fine details that the aio's make easy to see.

    for instance--this is typical footage of a composite dvr(it doesn't matter weather it is pc based, or stand alone) with a composite camera. granted, the dvr did encode it with mjpeg, with 'quality' set to about 70-80, which should mean about 20-30% compression-- so there is some slight room for image improvement, but not much--i actually watched this happen, and the quality on the live view(a uncompressed view) is only slightly better...

    note how you really can't see any details-- like the warning on the gas pump, the lettering on the bus in the background, or the license plate on the van-- all crucial details if any of those hit your car.

    1a. just recently, there are some new cameras on the market that use hdmi to talk to the dvr, but there is very little selection for either cameras or recorders..
    1b. there are IP cameras that use a standard network-- those will have great picture quality, but to setup a network is going to be more complicated/expensive then anything else-- i can get quality cameras(read: very good image sensor, very large housing) for about $600/camera...

    2. dvr:

    broadcasting the gps info would require way more coding knowledge then i know... it should be more possible with pc-based dvr's then standalone units--theough many standalones like to run linux, so depending on your experience..

    most standalone dvr's that i look at have inputs that require 12v@3A continuous. remember that most non-ir cameras are going to consume about 150-200mA per camera.
    i am horrible at power calculations, but in the end, to run a camera system all the time would be equivalent to leaving a single headlight on...

    i think that is good for now-- i gotta get back to that work thing..
