1.1 Product Features
30KM 1080P Full HD Image Transmission
HM30 applies SIYI’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 to
better frequency bands, which means it always goes to work on the band with least
interference. With the standard omni directional antennas, HM30’s effective range
can reach up to 15 kilometers. With the long-range antennas, the range can be up
to 30 kilometers with full HD image transmission, real-time telemetry, and stable
control.
*The 150ms latency is an average result measured by using SIYI standard IP camera under the
following conditions:
H.265 format, 720p @ 30 fps, displayed in QGC v4.1 (low-latency mode): end-to-end latency is
between 130 and 180ms.
H.265 format, 1080p @ 30 fps, displayed in QGC v4.1 (low-latency mode): end-to-end latency is
between 180 and 250ms.
SIYI will release a new 1080p @ 60fps camera to effectively lower latency even more.
OSD Telemetry Display
Working with HM30, SIYI FPV app supports Mavlink telemetry overlayed with OSD
display. The OSD display information can be customized. FPV OSD with full HD
image will bring you endless fun.
