Product overview

The YANGDA Sky Eye-3HT-MU combines thermal observation, laser ranging and AI target tracking in a 2-axis gimbal camera for low-light and nighttime aerial operations. Its 1280×1024 thermal imager uses a 25–75mm infrared lens with 3x optical and 8x digital zoom for wide-area observation and detailed inspection. Applications include border monitoring, pipeline and infrastructure inspection, emergency response and coordinated tracking. A separate 3840×2160 wide-angle EO camera supports broad daytime imaging without zoom capability.

A quick-release mechanism enables tool-free installation, while unlimited yaw rotation and a pitch range of +45° to -164° support camera positioning. YDlink control software supports telemetry, video transmission and command control, with MAVLink integration for PX4 and ArduPilot systems on VTOL and multirotor platforms. Ethernet video output and MP4 recording provide 1080P/720P at 30fps. Local storage supports class 10 TF cards up to 128G in FAT32 or ex FAT format. Thermal sensor anti-scald protection allows 30s of direct sun exposure, with recovery within 24 hours.
