Fence line protection systems make use of fiber-optic perimeter sensors which link their sensors to global positioning so that, when the sensors detect a fence breach, they can deliver the exact latitude and longitude of an event, pinpointing the precise spot of trouble. Older systems would divvy up perimeter fences into zones. When a breach occurred, the sensors would report that something had happened somewhere within that zone, within 25 yards of the actual event. With the global positioning integration, the new sensors give the exact location of the breach. This saves response time, making nuisance alarms less time consuming and allowing a quicker response to real alarms.
What’s more, it opens up the sensors to new applications, such as overlaying alerts with maps and automatically moving cameras to zoom in on the trouble spot based on the coordinates of the event. For years, fences have been evolving to become complex security systems that include barriers, traps and intrusion detection. Recent advances include electronic motion detection and infrared cameras.
