Product Overview
Built for night operations, the Sky Eye-HT75-M is a 3-axis drone gimbal camera combining precise detection with intelligent tracking. Its dual thermal imager — a 75 mm UHD lens with 8× digital zoom and a 13 mm wide-angle lens, enables accurate and broad early detection even in low-light conditions. With built-in AI tracking and a laser rangefinder, it provides real-time monitoring of targets, delivering reliable, data-driven, and efficient support for ISR, delivery, rescue, and inspection missions.

75mm Upgraded IR, Enhanced DRI Distance
Serving as the main IR sensor of the Sky Eye-HT75-M, this 75 mm thermal imager features UHD 1280×1024 resolution and 8× digital zoom, delivering sharper observation and extended DRI performance — with human detection up to 3,125 m and vehicle detection up to 9,583 m — enabling precise target identification even in low-light and low-visibility conditions.

13mm Wide-Angle IR, Extensive Vision Coverage
Built for informative night surveillance, the Sky Eye-HT75-M features a second thermal imager with a 13mm lens, 640x512 resolution, 8x digital zoom and wide-angle vision — providing a FOV of 32.9°horizontal, 26.6°vertical, and 41.4° diagonal — enabling detailed observation with wide-area coverage.

Adaptive Thermal Vision, Wider Operational Range
Featuring dual thermal imager and up to 20 thermal color palettes, the Sky Eye-HT75-M delivers versatile performance for a wide range of operational needs — from close target detection to long-range inspection — enabling traceable, informative, and modern surveillance ideal for night ISR, delivery, or rescue missions.

5km LRF, Target Under Control
Configured with a 5 km laser rangefinder, the Sky Eye-HT75-M provides precise location, altitude, and distance measurement of any target within 5,000 meters, offering strong backup for efficient, responsive and real-time tracking.

3-Axis Gimbal, Flexible Aerial Vision
Mounted on a 3-axis gimbal, the Sky Eye-HT75-M supports omnidirectional vision with yaw rotation 360°, pitch rotation ±90°and roll rotation ±45°, enabling a comprehensive footage for accurate surveillance.

AI-Powered Targeting, Detection in Precision
Configured with AI recognition and tracking, the Sky Eye-HT75-M automatically identifies and follows suspicious vehicles and individuals, while simultaneously transmitting precise location data to control center.

Fly By Camera, Autonomous Tracking
A surveillance VTOL can follow and monitor a stationary or moving target of interest along a routine patrol route if the onboard drone zoom camera tracks it. Additionally, the target's coordinates can be copied and shared with the command center. Once the monitoring is complete, the VTOL drone can return to its original patrol route.

Monitor Target Movement Status Via GCS
The pilot can use the LAUNCH GCS to monitor the target's movement status, such as real-time updated GPS coordinates, the distance between the target and the drone, as well as the distance between the target and the HOME position.

Fast Deploy & Easy Operation
Applying the self-developed YDPORT mechanism and YDLINK software, the Sky Eye-HT75-M achieves both hassle-free assembly/disassembly and intuitive operation, making drone surveillance attainable and adaptable on most drones and VTOLs.

MAVLINK Compatible
The Sky Eye-HT75-M drone gimbal is compatible with drones powered by PX4 and Ardupilot, making integration relatively convenient.
