SFG-330Q
Product Introduction

The SFG-330Q is a dual-axis, four-sensor screw-stabilized gimbal, designed with an integrated industrial structure. It is equipped with a continuous optical-zoom visible-light camera, a long-focus short-wave camera, a continuous-zoom mid-wave cooled infrared imaging module, and a laser illuminator.

It can be widely adapted to various manned/unmanned helicopters, fixed-wing and rotary-wing UAVs. It is primarily used for ground-target imaging, detection, tracking, identification, positioning, and guidance, meeting the needs of route inspection, accident investigation, emergency rescue, law-enforcement evidence collection, and counter-terrorism/security operations.
