A few weeks ago I helped a friend install a cheap security system at a small plaza. We used the cheapest “Made In China” generic cameras and an $8 PCI DVR capture card for an old PC computer. The quality of the video feeds and the features of the DVR software left a lot to be desired. We upgraded the system with four Sony color IR CCD sensor CCTV cameras and an EverFocus EDSR400H stand alone digital video recorder unit.
