The recent necessity to protect military bases, convoys and patrols gave serious impact to the development of security systems for perimeter protection. The application of multi-sensor increases functionality and performance of the whole system. Effective ranges of detection depend on the class of the sensor used and the observed scene itself. One of the most important devices used in such systems are IR cameras. Application of IR camera increases the probability of intruder detection regardless of the time of day or weather conditions. It also increases the probability of intruder detection and simultaneously decreased the false alarm rate produced by the system. The paper discusses technical possibilities and limitations to use uncooled IR camera in a multi-sensor system for perimeter protection. The role of IR cameras in the system was discussed as well as technical possibilities to detect human being. The operational distances for perimeter protection are rather high, considering parameters of commercially available thermal cameras. Comparison of exemplary IR cameras, capable to achieve desired ranges was done. The required spatial resolution for detection, recognition and identification was calculated. The simulation of detection ranges was done using NVTherm software. The results of analysis and simulations were finally presented.
