Distributed Wireless Surveillance System

A distributed wireless surveillance security system allows for a fast, clean installation with no wires to run. Video images, sound, and system status are transmitted over communication networks allowing remote monitoring.

Advanced wireless technology allows for the development of an intelligent surveillance system that does not need active monitoring. Using motion detection built into the camera, only video images from active zones are transmitted to the central controller for evaluation and possible action.

In a distributed system, remote re-configuration of programmable logic devices used in a system is advantageous. The "Leave Alone I/O" ability of the ispMACH 4000 or ispXPLD 5000 families allows pins to retain critical logic levels during "live" programming.
