Traditionally, the use of video technology in perimeter protection has played a secondary role. “In the past, outdoor video was forensic,” explains John Romanowich, president and CEO of SightLogix, a Princeton, N.J.-based manufacturer of video cameras with built-in analytics designed especially for perimeter protection.
In the traditional set-up, which some installers still use today, primary protection is provided by motion detectors, seismic sensors, photoelectric beams or like sensors. But because those sensors may have difficulty distinguishing between a human intruder and an animal, for instance, one or more cameras are often installed to provide a visual record of what actually occurred. Often the visual evidence is reviewed after the fact — and as Romanowich explained, more often than not the video footage does not clearly reveal what happened.
