EO SWIR MWIR LRF Long-Range Multi-Sensor Surveillance System | QJ-ECTLI-330

The QJ-ECTLI-330 is a long-range multi-sensor electro-optical surveillance system designed for advanced aerial and ground-based observation missions. It integrates a high-zoom visible camera, a cooled short-wave infrared (SWIR) sensor, a cooled mid-wave infrared (MWIR) thermal imager, and a long-distance laser ranging and illumination module. This multi-spectrum configuration enables reliable target detection and identification across day, night, and challenging atmospheric conditions.

The visible imaging module features a 1920×1080 resolution camera with a 10–300 mm focal length, supporting human detection up to 10.6 km and vehicle detection up to 25 km. The cooled SWIR sensor operates in the 0.9–1.7 μm band and enhances imaging capability in haze, smoke, and low-light environments. In addition, the cooled MWIR thermal camera with 3–5 μm spectral range provides high-sensitivity thermal imaging with NETD as low as 25 mK.

Equipped with a high-energy 1064 nm laser ranging and illumination module with a range exceeding 15 km, the QJ-ECTLI-330 supports precise distance measurement and target indication. The four-axis stabilized platform ensures high pointing accuracy and stable imaging, making the system suitable for long-distance surveillance, border security, maritime monitoring, and reconnaissance applications.
