    Have you got it so that you can control the streams on the front end? I want to be able to have all 4 on the screen or click on one and have it larger or any other combination of the streams.. I haven't seen any software that can do it though as they seem to get confused if all the cameras are the same..
    But yes I also want to record hi def video for use later as well.
    Yes I can view multiple cameras simultaneously. I can open multiple instances of my cameras on the screen simultaneously and click on any one to open full-screen if I choose to do so.
    I'll take a screen shot ad post it so you see.

    Windoiws 7 also has a great feature called "Flip 3D" that allows you to quickly preview all your open windows without using your taskbar.
    It displays all your open windows in a stack
    I also have a 3D mouse that looks like the BMW I-drive knob on the center console between the seats.
    I programmed one of the functions of the knob to enable flip 3d and I can just scroll between windows to the one I want and select using the same mouse.
    It is so easy to do that I can do it without taking my eyes off the road.

    In case you are not familiar with it., this is what it looks like:



    Here are pics of my center console with some accessories.

    There is already a minute lag in video from the cameras to the screen..... not that I plan on driving and relying solely on it, but imagine backing up close to something and hitting it before you can see on your screen that you have reached it.
    Hmm this is odd.. You should have next to nothing for lag...

    You are going to make me research a better mouse trap for this...

    My expectation is to make use of 1 ARM processor per paring of cameras.

    Will have to check into it more as I get closer to trying this... But in my case I would be doubling up the cameras for depth perception. Luckily OpenCV can do most of the software coding for you here...

    The ARM processors I am using are designed to be used with 2 cameras at the same time and use the GPU to do lots of cool stuff with OpenCV so this might be a good way to go too.

    After a long day today, I have finally got them working.
    Suffice to say I am too exhausted to go over all the details of my ordeal but here is a teaser video I shot using my iPhone.
    Unfortunately I am too tired to go into the specifics right now but I will do so as soon as I get some rest.
    I also had to work on my sub woofers as well as reroute some wires to make my install cleaner so I did not have the time to take pics as i was working as it was just a lot of trial and error to get where I am.
    More details to come soon

    Cool,
    How do you connect the three cameras ? Directly on your PC or through an interface ?

    These are USB webcams. They connect directly through the available USB ports on the computer

    So as a result of my testing, I have come to one basic conclusion.
    There have been lots of people having the same issues with setting up multiple cameras .
    Here is the simplest way I can explain it.

    The rule of thumb is if you are using multiple USB webcams of the same make and model, they each have to be connected to a separate USB hub. The real problem is that the device ID that is assigned by the manufacturer is the same for both of these devices when they are connected to the same hub. As a result windows may distinguish them as 2 devices in the device manager but being that the device IDs are the same you cannot get both to work simultaneously.
    You can connect different cameras with different drivers to the same hub but not verse versa.

    At this point, I am not so sure I want to use another Lifecam Studio for my rear view set up.
    I think it will just present too many challenges with me having to use multiple USB Hubs (1 for each camera). If I had additional devices to use those hubs it will make sense. In my opinion, 2 hubs for 4 cameras is a much more sensible option.

    I also have an Avalanche I will be doing something with.

    Not sure I will go the route you did but it is still pretty cool.

    I may end up using 8 Cameras to allow for "3d vision" but I am unsure.

    Have you been able to keep video going with this with more than one camera?

    If you have issues you could end up getting some very cheap Atom or ARM based computers and let them do all of the encoding then have your main PC work as a server for their files and let them just store the files through the LAN ports on your drive. Then your main PC only has to read the data streams.

    Consider that a Rasberry PI will run Linux, is tiny and is very cheap... If you were able to hook a USB camera to it and it has a LAN port you could easily stream data to your main PC allowing the Rasberry PI to do all the "dirty" work...

    You just had to throw a monkey wrench in my plans didn't you?
    I am not completely done with this project and now you have me thinking of 3D to give me depth perception.
    While I must admit the idea of using 8 cameras for 3D is much more than I can do, I am now considering changing the front view camera at least to 3D.

    During my research, I came across this little gem that would work perfectly attached to my rear view mirror.

    I am just a bit worried about the size being larger than it looks on the site.

    Just edit the PID in the registry. Add a _1, _2, _3 and so on to the Device identifier. I've run 3 identical Logitech Webpro9000 cameras connected directly to the PC by using the registry hack.

    Thanks for the reply sounds good.
    So what software is doing the recording / display?

    I like the sound of changing the pid as like you I don't want heaps of hubs.. Although nice to know that is also an option if required..
