I need to put a 24 hour surveilance camera in my store. I'd like to see everyone coming in and out of the back entrance. Our store runs 24 hours a day. I don't need multiple camera, just one. It has to provide clear picture, black and white is fine. Most importantly, it has to be running 24 hours a day, 7 days a week.
Any recommendation? I don't need a super gizmo, just a simple reliable one that doesn't break down and low cost. I rather not use VHS recorder.
Does anyone know how much I could record in a 80 gig hard drive in standard TV resolution? Does it matter if it's black & white or color?
