DX3A Miniature 4K EO Gimbal Payload

1. DX3A Miniature 4K EO Gimbal Payload Overview

The DX3A is an ultra-lightweight three-axis EO gimbal payload designed for UAVs, drones and compact airborne surveillance platforms. Weighing only 240 g, it integrates multiple visible-light imaging channels, dual 4K image sensors and a laser rangefinder into a compact CNC-machined metal housing. The system delivers 3840 × 2160 video at 30 fps, 40× continuous optical zoom and up to 120× hybrid zoom, while supporting automatic target recognition, target tracking, image compression and laser ranging up to 1200 m. With high-precision gyro stabilization and a compact integrated design, the DX3A is suitable for public security, inspection, environmental monitoring and other missions requiring lightweight long-range electro-optical observation.
