Product overview
The YAHREE A4 Pro is a drone-mounted imaging payload for inspection, surveillance and long-range reconnaissance. Its four sensing elements combine a visible-light zoom camera, a wide-angle camera, a thermal imager and a laser rangefinder within a three-axis stabilized gimbal. The aviation-aluminum pod measures 106.7 × 92.5 × 126.7 mm and weighs 470 ± 10 g, defining the main installation envelope. Integration also involves a separately specified 50 × 50 × 20 mm buck converter weighing 56 ± 5 g. The pod has IP43 protection and an operating temperature range of -20°C to 60°C.
The imaging configuration provides 48.0 MP visible-light sensors, 11X optical zoom, 176X hybrid zoom and a 640 × 512 thermal channel. Ethernet video output is 1920 × 1080 at 30 fps, while JPG images and MP4 video use Micro SD storage from 32GB to 512GB. Control options include S.BUS, TTL serial communication, TCP and UDP, with tracking and pointing modes. The pod requires 12V and 13W; its converter accepts 14–60 V, and independent pod power is mandatory. Target positioning requires GPS reception, with calculation accuracy of ≤ 10 m under non-complex terrain conditions.
