To promote intelligent and unmanned border management and control, heavy‑duty erect multi‑spectral anti‑reconnaissance devices have been installed in batches at multiple key prevention‑and‑control zones. Developed for extreme field operating conditions, the unit adopts an integrated sand‑colored military‑grade reinforced housing with an IP67 protection rating. It can stably withstand an extra‑wide temperature range from ‑40℃ to +65℃, resisting Gobi sand‑dust, coastal salt spray, intense sunlight, heavy rain, snow and other severe field climates. It is suitable for long‑term on‑site security missions in most border defense zones, energy bases, mining areas and perimeters of critical hubs.
Equipped with a high‑precision high‑load servo gimbal system, the device supports 360° continuous rotating cruise and accurate pitch positioning with a positioning accuracy up to 0.01°, minimizing monitoring blind spots. Integrated with high‑definition visible‑light imaging, high‑sensitivity infrared thermal imaging and laser ranging modules, it forms a complete multi‑spectral fusion perception system for day‑and‑night surveillance. In daytime, high‑definition optical imaging performs long‑range scanning and detail recognition. At night, infrared thermal imaging captures heat signatures from human bodies and observation equipment without being affected by darkness, shadows or low‑light conditions. The laser ranging module accurately calculates target distance, bearing and geographic coordinates.
Fixed on steel poles or concrete monitoring piers, the equipment operates without on‑site personnel and conducts automatic cyclic scanning along pre‑set patrol routes. Once optical threats such as telescopes, observation scopes and long‑range camera reconnaissance devices are identified, the system locks onto targets instantly, saves on‑site image evidence, and pushes azimuth, distance and latitude‑longitude coordinates to the back‑end command‑and‑control platform with sub‑second alarm response.
Networked linkage among multiple units enables seamless coverage of long strip‑shaped zones, greatly reducing workload for front‑line patrol staff. After reliability tests under simulated sand‑dust and salt‑spray environments, multiple prototypes have maintained stable performance over more than one hundred consecutive days of non‑stop operation. It delivers a robust technical protection solution featuring “early detection, fast positioning and timely alarm” for key field areas.
