Long-Range EO/IR Systems

Long-Range EO/IR Surveillance Systems

A two-axis gyro-stabilized turret carrying a visible/near-infrared continuous zoom camera (up to 2000 mm) and a continuous zoom thermal camera (up to 1200 mm), with an optional eye-safe laser rangefinder. Automatic detection and tracking run on the system. The thermal camera can be cooled MWIR or uncooled LWIR. Country of origin: overseas (non-PRC).

Vehicle targets are 2.3 × 2.3 m and person targets 0.5 × 1.8 m; detection, recognition and identification correspond to 1, 3 and 6 line pairs on the target. Calculated per STANAG 4347 with the TRM4 model: 50% probability, 2 K target-to-background temperature difference, 0.18 /km atmospheric attenuation. Actual ranges depend on weather, atmosphere and target, so use these figures for comparison only. Horizontal fields of view are rated values with ±5% tolerance.

Software and integration

  • Remote operation of one or several systems, with web and touchscreen interfaces and concurrent multi-user access
  • A map view of each station's viewing direction and coverage; configurable exclusion zones, surveillance sectors and patrol routes
  • AI-based automatic detection and tracking of vessels, vehicles, people, drones, smoke and fire; the turret follows the tracked target automatically
  • Geo-referenced alarms and events, with integration into third-party monitoring platforms through an API or the ONVIF protocol

Suited to perimeter monitoring of airports and critical sites, border and coastal surveillance, maritime surveillance and vessel traffic services (VTS), and long-range observation and tracking of aerial targets, including drones. To bring several sites, laser ranges and track data into the operating picture of a command center, see C2ISR integration.
