Product Overview
The SSK/NW-IRS1500 series high-definition, medium-range, three‑band night‑vision system comprises near‑infrared laser imaging, long‑wave infrared thermal imaging, and visible‑light low‑light imaging, along with a control subsystem. It effectively meets day‑and‑night imaging requirements in 24‑hour, all‑weather conditions, supporting nine selectable color palettes for color, black‑and‑white, laser‑illuminated night‑vision, and infrared thermal images. The system delivers crisp image quality and excels at revealing fine details, even in foggy conditions or under low‑light levels, with a resolution of 2 megapixels.
This series of high-definition, medium-range, roof-mounted, three‑band night‑vision systems offers a maximum detection range of 5,000 meters and a maximum identification range of 2,000 meters. Its highly integrated, all‑in‑one design simplifies and accelerates installation, making it an excellent choice for night‑vision surveillance projects. The products have been successfully deployed across diverse sectors, including forest fire prevention, petrochemicals, natural disaster monitoring, military border defense, maritime and water‑resource management, navigation channels, nature reserves, public security and armed police forces, airports, cultural heritage protection, and the energy and mining industries.

Product Features
Day/Night Auto‑Focus: At the day/night threshold, the system automatically switches between color and black-and-white imaging, delivering crisp, clear images 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 for 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 clear, crisp image.
Dual-synchronous rectification technology: The device employs dual-synchronous rectification for power supply, achieving a power conversion efficiency of over 97%.
Strong‑light suppression and protection function: To prevent rapid aging and damage to the CCD/CMOS sensor under intense illumination, this product is equipped with a strong‑light suppression feature. When exposed to bright light, it instantly disconnects the CCD/CMOS sensing interface, effectively safeguarding the sensor from damage caused by excessive light.
Defogging Function: The device is equipped with an anti-fog window, and the system can penetrate fog under moderate climatic conditions.
Synchronized zoom function: In night‑time laser‑enabled mode, the laser’s beam angle automatically adapts to the camera system’s field of view, enabling the laser spot to track and adjust in real time as the lens’s viewing angle changes, while simultaneously modulating the laser’s irradiation 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 an external dust‑proof, water‑resistant 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.
Dual-video overlay technology: It can simultaneously display both visible-light and infrared images on a single screen, with seamless switching between the two.
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.
