Hi, We plan to use a webcam in an embedded project for building a sort of surveillance camera system. In short we take a few pictures an hour and submit those using GPRS or UMTS. The embedded system consists of an embedded linux board (Fox board lx832) build around a ARM9 cpu. The board contains two USB 1.1 ports and to one of those the webcam will be connected.
First of all not much webcams offer high resolutions. Logitech has a bunch of those (e.g. QPC 9000 Pro / Sphere AF) and most others I found from Trust, Hercules seem to use the Microdia chipset which doesn't have an opensource driver yet. Does someone have other suggestions for webcams that offer good image quality and if possible a high resolution? Another issue is of course that I'm limited to USB 1.1. I don't think the bandwidth is much of a problem as I don't need much images and don't need them frequently either. Second jpeg compression is fine by me (but I would like to be able to adjust the compression parameters). Does USB 1.1 somehow limit the resolution of the pictures I can take? I can imagine that the buffer size is smaller than the max image it can take and that USB2 is fast enough to empty it before data gets overwritten.
