Hex Herelink HD V1.1 2.4GHz Video Transmission System

The Hex Herelink HD V1.1 is a 2.4GHz digital video and telemetry system for professional UAV platforms running ArduPilot or PX4—survey, mapping, agriculture and heavy-lift builds where mission planning, real-time telemetry and BVLOS range matter. The air unit transmits HD video over 2.4GHz whilst a separate 900MHz link carries MAVLink RC and telemetry, keeping control authority intact during video dropouts. The ground controller integrates an Android-powered 5.46" touchscreen running QGroundControl, merging radio transmitter, video receiver and flight-data display in one handheld unit.

Key features

• Dual independent RF links: 2.4GHz adaptive-bitrate video downlink avoids 5.8GHz congestion, 900MHz frequency-hopping RC/telemetry link ensures control even when video drops

• MAVLink-native integration streams live flight parameters, mission status and vehicle state directly to the controller display; SBUS and PPM outputs on the air unit for legacy flight-controller compatibility

• AES-encrypted video transmission and interference-rejection hopping protocol for operational security and regulatory compliance

• Ground controller runs Android OS, supporting custom GCS apps and third-party mission software beyond QGroundControl—log telemetry, export flight data, install regulatory documentation tools

• Line-of-sight range up to 20km (regulatory and environment dependent), 100–130ms video latency
