Security systems

Buying guide

Here you will find video surveillance cameras and recorders, fire alarms, access control systems and intercoms. Before choosing a camera, decide whether you need an IP or an analogue system: an IP camera connects by network cable and works with an NVR recorder, an analogue one by coaxial cable with a DVR. The recorder needs at least as many channels as you have cameras, and the hard drive that stores the footage is often sold separately. If a camera supports PoE, a single cable carries both power and video.
