The thermal monocular STRIX is built around up-to-date high-sensitive microbolometer TiO2 and designed for round-the-clock supervision, search and video registration of objects during regular and severe weather conditions in a thermal spectral range from 8 to 14 microns. Combination of advanced sensor and high-resolution monitor gives excellent image even at very bad weather conditions. Detachable range finder LRF700 can be mounted on monocular. The CPU automatically identifies a rangefinder and transmits the information on a display.
