Perimeter security goes high-tech
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.
"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.
