EO + Cooled MWIR Thermal + Laser Rangefinder Long-Range Surveillance Payload | QJ-ETLI-200

The QJ-ETLI-200 is a compact long-range electro-optical surveillance payload integrating a high-zoom visible camera, a cooled MWIR thermal imager, and a precision laser rangefinder. Designed for airborne and ground-based monitoring platforms, it provides reliable day-and-night target detection, tracking, and distance measurement for long-distance surveillance missions.

The visible imaging system features a 30× optical zoom lens with a focal length of 4.3–129 mm and 1920×1080 resolution, enabling wide-area observation and long-range identification with vehicle detection up to 15 km. The cooled MWIR thermal imaging module operates in the 3–5 μm spectral band with a 40–220 mm continuous zoom lens, delivering high-sensitivity thermal imaging even in low-visibility conditions.

The integrated 1064 nm laser rangefinder measures distances up to 8 km with ±5 m accuracy and supports coded laser illumination for extended target designation. Combined with a stabilized 360° gimbal and intelligent multi-target tracking, the QJ-ETLI-200 provides stable imaging and accurate target monitoring for applications such as border security, maritime surveillance, reconnaissance, and infrastructure protection.
