I am currently running one camera at 640x480 but the quality is aewful, especially when there is motion. See http://www.ginnungagap.net/zmexample20040624.jpg for a screenshot
How can I improve it so that I can see faces and number plates?
I think that is all the info i have for now, if anything else is needed apologies for missing it out!
Thanks in advance
Pete
