I want to setup an outdoor security camera that's connected to my PC via my LAN (could be wired or wifi). The PC would only record to the hard drive when there is motion so save disk space. I know they have cameras with motion sensors in them so the camera only records when there is motion, which would be okay too, if there isn't too much of a delay. On the PC I'd set the number of MB or hours it will store on the hard drive, then the system will just delete the older video to make room for the new video being recorded. Can anyone recommend a system that does this, or point me in the right direction to build my own. I prefer Windows XP for the OS, but I could do it in Linux also.
