From 24-hour duty along border defense lines to vessel supervision in coastal areas; from perimeter security at airports to hazard inspections in industrial parks — the 15–315 mm and 21–460 mm mid-wave infrared lenses have been deployed in multiple critical security scenarios, demonstrating their core advantages of “wide coverage, long-range identification, and all-weather operation,” and becoming a powerful tool for surveillance upgrades across various fields.

I. Border Security: Full Coverage of 5‑km Defense Lines, Accurate Detection of Targets Beyond 10 km

In key border regions, the 15–315 mm mid-wave infrared lens system has achieved the dual objectives of “wide-area monitoring + precise tracking”:

With a horizontal field of view of 25°–40° in wide‑angle mode, it easily covers border lines up to 5 km long, eliminating blind spots between segmented surveillance zones. Upon detecting abnormal activity, switching to the telephoto end enables detailed capture of personnel movements and vehicle tracks at distances of 8–10 km. High-definition images are transmitted in real time, providing precise intelligence to border patrols and significantly improving response speed in border defense.

II. Coastal Surveillance: Ship Recognition at 9–10 km, Building a Multi‑Layer Maritime Defense

Coastal cities have adopted the 21–460 mm lens system to establish maritime surveillance networks, addressing the challenges of “numerous near‑sea blind spots and difficult long‑range identification.”

At the telephoto end, the lens can clearly identify vessel types, navigation status, and even capture details such as hull markings and crew activity at distances of 9–10 km. Integrated with radar systems, it forms a multi‑layer monitoring framework combining “infrared imaging + radar warning,” effectively preventing illegal crossings, maritime emergencies, and enhancing the efficiency of maritime safety supervision.

III. Airport Perimeter: Threat Prevention at 4–6 km, Safeguarding Aviation Security

In international airport perimeter protection, the 15–315 mm lens system demonstrates unique “all‑weather + long‑range” capabilities:

Wide‑angle mode covers critical areas such as runway surroundings and terminal exteriors, providing 24/7 gap‑free monitoring to prevent risks like unauthorized entry or foreign object intrusion. The telephoto end enables early identification of potential threats (e.g., suspicious vehicles or objects) at distances of 4–6 km, giving airport security personnel ample time to respond and reinforcing aviation safety defenses.

IV. Industrial Parks: Full‑Area Coverage + Focused Tracking, Optimizing Safety Management

After introducing the lens system, large industrial parks have achieved a balance between “comprehensive monitoring and prioritized attention.”

Wide‑angle mode eliminates blind spots in workshops, warehouses, and transport passages, reducing gaps in hazard inspections. In case of equipment anomalies or personnel violations, zooming in quickly focuses on key areas, delivering real‑time high‑definition footage to assist safety personnel in accurate intervention and lowering operational risks.

V. New Trend of Technology Integration: AI + Multi‑Sensor Collaboration, Driving Intelligent Surveillance Upgrades

With advances in artificial intelligence and multi‑sensor technology, the 15–315 mm / 21–460 mm mid‑wave infrared lens systems are moving toward a “smarter, more efficient” stage:

Integration with visible‑light imaging, laser ranging, and other technologies enriches the dimensions of surveillance data, achieving full‑scene coverage with “infrared night vision + visible‑light daytime + laser ranging.” Equipped with advanced AI algorithms, the system can automatically identify targets such as personnel, vehicles, and abnormal behavior, enabling “automatic alerts and intelligent analysis,” reducing manual monitoring workload, and improving warning accuracy.

VI. Forward Outlook: Unlocking More Scenarios, Leading New Directions in Security Technology

The practical deployment of the 15–315 mm and 21–460 mm mid‑wave infrared continuous zoom lenses not only validates the core value of mid‑wave infrared technology in the security field but also highlights the broad application prospects of modern optoelectronic technology. In the future, with ongoing upgrades in optical design and AI algorithms, such lens systems will further expand into more areas such as forest fire prevention, urban security, and power line inspection. They will provide more reliable and intelligent technical support for various surveillance scenarios, accelerating the security industry’s progress toward “comprehensive perception, precise warning, and efficient response.”
