Borders and coastlines often have a complex terrain spanning vast areas with various and harsh weather conditions. Ordinary monitoring systems cannot withstand all weather conditions, and fail to meet long range intrusion detection requirements. Thermal (infrared) Imaging systems on the other hand, have long detection and recognition ranges, can be operated and functional in extreme weather conditions, day and night, and they can identify the infrared spectral characteristics of targets. This makes Thermal Imaging systems an ideal choice for long range reconnaissance and detection in border zones.
