From towers and moats to modern walls and wire mesh, physical perimeter fortifications have been around for millennia. Today’s technology brings us various types of electronic perimeter protection systems, mainly detecting or possibly preventing would-be intruders from crossing over into protected areas.
Now, most traditional perimeter protection systems use active infrared (IR) detection. However, this type of detection method falls short in stability and reliability. Just before an intrusion happens, or while it is happening, traditional IR cannot make accurate predictions, and, lacking video data, it can be rather difficult to locate key alarm points. Furthermore, terrain, environmental and other factors often cause underreporting, false alarms or other inaccurate results.
In order to resolve these problems, Hikvision’s Turbo HD passive infrared (PIR) camera uses advanced video surveillance technologies to improve alarm accuracy. With its rapid response rate and alarm accuracy when suspicious people cross established perimeters, it enhances perimeter protection for residential areas, around factories, warehouses, schools and other settings.
The camera has a built-in PIR detector that captures infrared light given off by human bodies and distinguishes it from other visual ‘noise’. It can be equipped with Hikvision’s Turbo HD K series DVR’s motion detection to filter false alarms caused by moving targets without human body IR emission. This way, filtering false alarms reduces storage space and costs, and it also means more efficient post-event footage search.
In addition, the camera features a strong and immediate deterrent by producing a flashing white strobe light that serves as a warning signal to stop intruders. With ultra-low-light technology, the white light serves as supplemental lighting, enabling the camera to capture clear images of suspects as evidence when the alarm is triggered, even in extremely dark environments.
