ASTROHN-2A

Thermal imaging complex for the railway infrastructure security

The ASTROHN-2A thermal imaging modules are the basic elements of the distributed security system for the railway and railway facilities. ASTROHN-2A includes the last achievements at the field of thermal imaging surveillance and video analysis. Thermal imaging module ASTROHN-2A is the block of the full factory readiness installed on the catenary masts and connected to the data acquisition and handling system (DAHS) by the optical fiber. The special mounting at the mast excludes the complex’s periodic motion at the high-speed train passing and does not influence the built-in intellectual video analysis system. The modules are designed considering the ASTROHN-like security systems for the contiguous areas of Gazprom and Russian Railways significant operation experience. ASTROHN-2 is in serial production since 2009. By 2016 there are more than 3,000 complexes in operation. The operating conditions are: 24/7, all year round. The maintenance service includes warranty maintenance and post-guarantee maintenance with replacement if its necessary within 24 hours at the ASTROHN’s service centers.
