Hi, Am I missing something?
Isn't there a low-resolution camera that puts out JPEG data? I have a 640x480 JPG here with some big text on it that's 25K.
Couldn't Arduino move that kind of data to a PC??
Yes there is, and I don't see why the Arduino couldn't take the byte stream and push it out over a network connection. I don't know what sort of encoding would be required, and that might be a problem, but perhaps not an insurmountable one.
I suspect it would be possible to get an IP camera with an FTP capability built in (I have one that is triggered by motion detection - I suppose there is probably something similar that will do it on a timed basis) which would probably be easier to use as well as cheaper than the Arduino solution.
