EO + Cooled MWIR Thermal + Laser Rangefinder Surveillance Payload | QJ-ECTL-200

The QJ-ECTL-200 is a stabilized electro-optical surveillance payload integrating a high-definition visible zoom camera, a cooled mid-wave infrared (MWIR) thermal imager, and a precision laser rangefinder. Designed for airborne and mobile monitoring platforms, it enables reliable target detection, identification, and tracking in both daytime and nighttime environments.

The visible imaging module features a 1920×1080 resolution camera with a 30× optical zoom lens (4.3–129 mm), providing wide-area observation and long-distance 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. Combined with a stabilized 360° gimbal platform and intelligent multi-target tracking capability, the QJ-ECTL-200 offers stable imaging and accurate monitoring for applications such as border surveillance, maritime security, aerial reconnaissance, and infrastructure inspection.
