For securing critically important areas, a barbed wire-topped fence may not be enough, SecurityInfowatch.com advises. Radar might be added to insure redundancy.
Where perimeter protection is essential – as at utilities and airports – “it is imperative to deploy multiple best-in-class sensors to improve detection times and deliver real-time, dynamic situational awareness to security personnel. Deploying fixed and multispectral pan-tilt-zoom (PTZ) thermal cameras in a PIDS, for example, can ensure security operators maintain visibility of their perimeter even after dark and increase detection range beyond what a standard visible surveillance camera can see.
“One predominant trend for creating redundancy in this sort of perimeter security infrastructure involves implementing ground-based radar systems alongside both thermal and visible light sensors. According to the 2019 Perimeter & Drones Security Report from IHS Markit, ground-based radar systems are becoming a much more common option for perimeter protection applications.”
So, if the need is critial enough, don’t get caught relying on a barbed wire fence or surveillance cameras alone.
