Overview of Product


Designed for critical infrastructure and national-scale surveillance missions, this system delivers persistent day-and-night monitoring capability under extreme environmental conditions. By combining cooled MWIR technology with long-range HD visible optics, it ensures target detection, recognition, and verification regardless of lighting conditions, fog, haze, or temperature variations.

Its industrial-grade IP66 housing, anti-salt-fog protection, and wide temperature tolerance (-40°C to +55°C) ensure long-term stability in coastal, desert, or high-altitude deployments. The system is mounted on a heavy-duty intelligent variable-speed gimbal supporting 360° continuous pan rotation, ±45° tilt, and up to 256 preset positions. Integrated intelligent analytics include regional intrusion detection, cross-border intrusion detection, multi-scene cruise detection, and 3D frame selection zoom positioning.



Product Features


The MCT cooled detector enables superior long-distance detection compared to uncooled alternatives.

≤20mK thermal sensitivity enhances early detection of minimal temperature anomalies.

Long focal visible optics provide detailed identification at extended ranges.

Intelligent analytics significantly reduce operator workload and false alarms.

Independent defogging and defrosting module ensures optical clarity in high-humidity environments.

Low power consumption (≤110W) supports continuous 24/7 operation.
