Application specific movement detectors

Designed for sensing within larger rectangular areas such as hotel lobbies and long corridors, the 18.41 surveys an area up to 15m either side of the device, giving an extensive total detecting zone of 30m long by 4m, from just a single unit.

Central to the 18.51 is an advanced lens and electronics system that achieves two detecting zones with different sensitivities. The central 4 x 4m zone responds to very small movements, able for example to pick-up on the presence of a person quietly working at his workplace. Additionally, within an extended 8 x 8m zone, it will also respond to normal movements. This product is particularly targeted at offices, schools, and the workplace in general.
