SIYI HM30 - Integrated Digital Transmission System for Long Range in HD Resolution
SIYI HM30 is an advanced long-range digital transmission system designed to provide Full HD video and ultra-low latency telemetry for FPV aircraft, commercial drones and unmanned vehicles. With advanced features and high performance, the HM30 system ensures reliable FPV and long-distance control.
Key Features
- Transmission Range: Up to 30 km with Full HD (1080p) video at 60 fps, ideal for long-term FPV and control applications.
- Ultra Low Latency: 150ms average latency with standard quality IP cameras.
- Frequency Band: Works in the range of 5100 - 5825 MHz with adaptive frequency selection focused on frequencies with minimal interference.
- Power: Approximately 25 dBm / 320 mW, with an effective range of up to 50 km under optimal conditions with high-power antennas.
- Antenna Compatibility: SMA connectors for interchangeable antennas on ground and air modules. As standard, it includes 4 omnidirectional antennas (2 ground, 2 air) and 2 directional antennas for the ground module. Optional high performance antennas (up to 17 dBi) and lollipop antennas are available for increased performance.
- Compatibility with Controllers: Mavlink telemetry support for Ardupilot, PX4, INAV and similar systems. Compatible with any control unit with S.Bus or PPM output.
- Full HD 1080p Video Transmission: SIYI's advanced HD video transmission technology, enabling 1080p quality video transmission at 60 fps with real-time telemetry and control stability.
Specifications
Low Latency Modes:
- H.265, 720p at 30fps: Latency 130-180ms (QGC v4.1, low latency mode).
- H.265, 1080p at 30fps: Latency 180-250ms (QGC v4.1, low latency mode).
- Newer cameras supporting 1080p at 60 fps aim to reduce latency even more.
OSD Telemetry (On-Screen Display): Integrated display of Mavlink telemetry with the ability to customize overlay data. Provides real-time telemetry in Full HD, enhancing the FPV experience.
Ground Unit Functions
- OLED Touch Display: Displays current system status in real time, with quick access to settings for easy configuration in the field.
