This dual-sensor camera can also be optionally fitted with a super-homogenised NIR laser serving as a light source. Combined with a low-light HD camera, it enables detailed observation of targets detected by night-time thermal imaging, thus forming a three-sensor camera that combines infrared thermal imaging, the visible spectrum and the NIR laser for day and night reconnaissance, making it suitable for long-range target surveillance in all weather conditions. It can also be supplemented with a laser rangefinder, a Beidou/GPS system, an electronic compass and other sensors and accessories, enabling the acquisition of precise location data on targets and long-range scenarios, and forming a multifunctional long-range surveillance system for situational awareness.

These dual-sensor cameras can also operate with the dedicated software of the DF3000/FR4000 key area defence platform, which enables the implementation of its intelligent functions such as regional intrusion detection, cross-border intrusion detection, detection of moving groups in multiple scenarios, selected 3D zoom/positioning, automatic target tracking, panoramic mosaic, radar linkage, etc., and to achieve unattended automatic operation.

This series of cameras is equipped with a built-in intelligent hotspot detection algorithm, capable of automatically detecting flames, vehicles, people and other heat-emitting targets at long range; it can detect the source of a fire and display an alert within a radius of 6,000 m. Thanks to the dedicated FR4000 software of the fire alert platform, it offers functions for automatic scanning, automatic processing of emergency information, automatic recording, automatic calculation and calibration of the fire location, virtual area management, GIS map information display, access to meteorological
data, hierarchical management, dynamic monitoring of the fire situation, rescue strategy and other functions. This camera is suitable for forest fire prevention, monitoring of pastures, coal mines, large grain silos and other long-range automatic monitoring applications for early fire warning.
