Product Overview
The SSK/NW-IRS3500 series high-definition, medium-to-long-range, three‑band night‑vision system comprises a near‑infrared laser imaging subsystem, a long‑wave infrared thermal imaging subsystem, a visible‑light low‑illumination imaging subsystem, and a control system. It effectively addresses day‑and‑night imaging requirements in 24‑hour, all‑weather conditions, supporting nine selectable color‑mode options—color, black-and-white, laser night vision, and infrared thermal imaging—and offering switchable imaging modes. With exceptional fog‑penetration capabilities and outstanding low‑light detail reproduction, this system not only meets the practical demands of industrial applications but also significantly enhances equipment utilization efficiency.
This series of high-definition, medium- to long-range, top-mounted, three‑band night‑vision systems offers a maximum daytime detection range of 5,000 meters and a maximum nighttime detection range of 3,500 meters. Its highly integrated, all‑in‑one design simplifies and accelerates installation, making it an ideal choice for construction and engineering firms seeking advanced night‑vision surveillance solutions. The product has been successfully deployed across diverse sectors, including forest fire prevention, petrochemical operations, natural disaster monitoring, military border security, maritime and water‑resource management, navigation channels, nature reserves, public security and armed police forces, airports, cultural heritage protection, and energy and mining industries.

Product Features
Day/Night Auto‑Focus: At the day/night threshold, color and black‑and‑white images switch seamlessly, delivering crisp, clear visuals without any manual focus adjustment.
Automatic illumination adjustment: The system automatically modulates the laser’s brightness in response to ambient light levels, ensuring that observed targets remain clearly visible within the effective viewing range at night while effectively preventing over‑ or under‑exposure.
External laser adjustment: An external fine-tuning mechanism ensures simple and straightforward alignment.
Grating homogenization function: The laser illumination system employs a multi‑stage homogenization and collimation process, ensuring uniform light exposure. The light spot maintains precise alignment and coaxiality with the CCD/CMOS imaging system, eliminating polarization effects and multi‑point refraction or reflection artifacts, resulting in a clean, sharp image.
Dual-synchronous rectification technology: The device employs dual-synchronous rectification for power supply, achieving a power conversion efficiency of over 97%.
Defogging Function: The system is capable of penetrating haze under moderate climatic conditions.
Synchronized zoom function: When the night‑time laser is activated, the laser’s beam angle automatically adjusts to match the camera system’s field of view, enabling the laser spot to track changes in the lens’s field of view and dynamically regulate both the laser’s angle and intensity.
Internal Temperature Control: The equipment is equipped with built-in heating and cooling systems that activate the heater at low temperatures and the cooler at high temperatures, ensuring long-term, stable operation under harsh environmental conditions.
Employing a multi-layer coating process and featuring an external dust‑proof, water‑repellent design that eliminates the need for wipers, this product prevents frost and fog from forming on both the inner and outer windows, making it well suited for field applications. It also effectively reduces engineering maintenance workload and associated costs caused by wiper blade aging.
Three‑protective outdoor powder‑coating process, resistant to salt spray and acid/alkali corrosion.
Application Scenarios
It can be widely deployed in low‑light and poorly lit environments that require extensive high‑definition surveillance, such as rivers, forests, highways, railways, airports, ports, guard posts, plazas, parks, scenic areas, streets, train stations, large venues, and the perimeters of residential communities.
