The electro-optical Monitoring System includes high-definition visible light camera, big array cooling infrared thermal imager, precision servo turntable, high-precision tracking module. It is a precision detection imaging device with outstanding performance features, high degree of automation. It can work stably for a long time, full time, all-weather and omnidirectional finding, tracking, identifying, monitoring targets. It is widely used in border and coastal defense, military bases, airports, nuclear and biochemical facilities and other key areas, key targets for three-dimensional security. The device not only can be used as an independent photoelectric detection equipment, to implement manual search, manual or automatic target tracking, but also can be linked with radar to achieve rapid discovery and identification of the target according to the target guidance information sent by radar.
