The PKI 5230 Long Range Thermal Imaging System is intended for the use in harsh applications including perimeter surveillance and coastal security. Therefore it perfectly matches the tasks of police-, military-, customsand border-control departments. It is a high performance thermal imager based on a indium Antimonide (InSb) 320 x 256, 30μm pitch focal plane array (FPA) and operates in the 3-5μm spectral range. Its sealed housing (backfilled dry nitrogen) and marine hard carbon coated lens with front element defroster makes it perfect in all conditions incl. snow and sea. The triple-FOV lens 250 – 1000mm/ F 4.0 allows a man detection up to 17km. Also the PKI 5230 Long Range Thermal Imaging System features RS232 /RS422 link for fast integration in any surveillance equipment.
