Triple-Sensor EO IR LRF UAV Camera 8K Imaging System | QJ-FETL-3
The QJ-FETL-3 is a compact triple-sensor UAV payload that integrates a fixed-focus 8K visible camera, a zoom visible camera, a 640×512 thermal imaging module, and a laser rangefinder. This multi-sensor configuration enables drones to perform high-resolution imaging, long-range observation, and thermal detection within a lightweight aerial platform.
The system includes an 8000×6000 fixed camera for ultra-high-resolution wide-area imaging and a zoom camera with a 15.3–49.7 mm focal length for long-distance observation. Combined with a 640×512 infrared sensor and a 905 nm laser rangefinder with a measurement range up to 1.5 km, the payload supports reliable target detection, identification, and distance measurement.
With a compact structure of ≤400 g and stabilized gimbal control, the QJ-FETL-3 is suitable for UAV applications such as inspection, security monitoring, reconnaissance, and search-and-rescue missions.
