Perimeter security - Thermal Imaging with Video analytics

Thermal cameras when used for perimeter security can reduce much of the noise caused by environmental conditions hence making it easier for video content analysis, thereby allowing easier detection and tracking targets of interest. Thermal cameras combined with video analytics can see over large distances typical of perimeter security thereby ignoring lighting problems which can trigger false alerts.
Introduction of high resolution thermal cameras has a big economic impact by lowering the costs to protect large perimeters. Although thermal cameras have come a long way in providing good black and white images with visual details throughout the day, they are still behind the level of details offered by HD visible cameras. Hence the best solution is to combine thermal cameras with visible camera for alarm assessment. 
Certain thermal cameras can automatically steer and zoom an associated HD camera onto the detected target in real time thereby allowing better perimeter security.
