HM30 is a 30KM level 150ms low latency 1080p full HD video link based onthe latest image transmission technology which is independently developedby SIYI Technology . Abundant features and powerful performance make it a commonly applied device of reliable FPV view and solid control on FPV planes , commercial drones , unmanned vehicles and boats , and robotics。

HM30 applies SlYI’s brand new and cutting-edge high-definition image transmission technology with the ability to transmit 1080p 60fps video stream at ” 150ms low latency. The technology comes with a smart feature to adapt its transmission toequency bands with the least interference. Equipped with the standard omni-directional antennas . HM30’s effectivcan reach up to 15 kilometers. With the long-range antennas , the range can be up to 30 kilometers with full HDimage transmission , real-time telemetry , and stable control.

The 150ms laency is an average resuit measured by using SIYI standard IP camea under the following conditions:
H.265 format, 720p @ 30fps, displayed in QGC v4.1( low latency mode ): end-to-end latency is between 130 and 180ms.
H.265 format 1080 @ 30fps, displayed in QGC v4.1 (low-latency mode): end-to-end latency is between 180 and 250ms.
SlYI will release a new 1080p @ 60fps camera to effectively lower latency even more.
