The S660H infrared thermal imaging video image surveillance forensics system is composed of an infrared thermal camera, a CCD high-definition camera, an electric head, an orientation information display module, a fully sealed anti-corrosion shield, and information terminal equipment. The front and rear environment of ships, marine resources, marine vessels, floating objects, etc. are observed, searched, and monitored around the clock (24 hours), and real-time video can be provided to provide detailed information for the processing of relevant departments. The system can be widely used in patrol ships, ocean-going freighters, ro-ro ships, inland ships, offshore drilling platforms and other offshore facilities. It is suitable for installation in open places such as ship decks and masts to monitor targets such as long-distance sea surfaces and ship decks.
