ASTROHN-3A
Multispectral protection device for the contiguous objects and transport infrastructure
ASTROHN-3A modules contains, apart from thermal imaging channel, the optical channel with the vision and recognition range up to 1,000 meters. The angles of sight of optical and thermal imaging channels are identical. Optical channel is mainly used during the daytime. Usage of low-level sensor in the cameras of visible band allows to use the optical channel at low illuminance (up to 0.001 lx). Thermal imaging and TV channels contain independent and synchronized systems of intelligent video analysis. Video transmission from thermal imaging channel, TV channel and meta-data of both channels is implemented by the optic fiber through the hermetic tamper-proof plug. The optic fiber plugs simplify modules’ repair and maintenance and its’ replacing without optical fiber fusion splice.
ASTROHN-3A modules are in mass production since 2010. More than 1200 thermal imaging modules ASTROHN-3A are in full time service by the year 2016. Operating conditions: 24/7/365. Mean time to failure – 10 years. Warranty period – 3 years.
