Perimeter security goes high-tech

Posted by Aharon Etengoff

Lockheed Martin and Intelleflex have developed an advanced perimeter security system that uses modified firmware, interrogation protocols and tracking algorithms to prevent unauthorized infiltrations.

"VAMS is [capable of] detecting stationary objects, single or multiple intruders, air-dropped items, left-behind items and even intruders who vault perimeter fences or drop by parachute," explained LM principal scientist Dr. Vibeke Libby.

Perimeter security goes high-tech"As an intrusion is detected, a camera is automatically cued and pointed at the intrusion coordinates for operator alarm and verification."

According to Libby, the automated wireless VAMS alarm system comprises a field of sensors that exchange information with a power source.

"A human infiltrator will affect one or more communication channels in the vicinity of an intrusion point. [However], an object or a human does not need to be in the direct communication path to affect the sensor [link]. 

"In fact, the disturbance is likely to affect several sensors in a protected area to varying degrees dependent on the relative position of intruder and sensors. This variation is used to determine the number of [infiltrators] and their location."

Libby added that VAMS was designed to detect both stationary and slow moving persons regardless of protective gear. 

"[So], compared to current security systems, the VAMS-camera combination can detect and verify intrusions designed to spoof traditional technologies, like motion, infrared, pressure, or security cameras.

"[The system] therefore poses a serious challenge to sophisticated intruders."

The wireless VAMS can be rapidly deployed either indoors or outdoors as a stand-alone, battery-supported security system.
