1 INTRODUCTION
1.1 Product Features
15KM 1080P Image Transmission
Once again SIYI made a breakthrough, applying this brand new and cutting edge
high-definition image transmission technology on MK15 successfully. The
technology comes with a smart ability 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, MK15 system’s effective range can
reach up to 15 kilometers. With the long-range antennas coming with MK15
enterprise combos, the range can be up to 30 kilometers with full HD image
transmission, real-time telemetry, and stable control.
Dual Full HD Low-Latency Video Stream Display
MK15 air unit supports standard RTSP video stream input through its standard
ethernet port directly or converted by HDMI module. The stream is up to two-way
1080p video simultaneously, latency low to *180ms. The pre-installed SIYI FPV
application supports switching display of two video streams between the main
screen and the floating window, and the video stream SDK is fully open to
developers. On agriculture drones, the feature works with front camera and back
camera for almost 360-degree visual protection. On commercial drones, the two-
way video stream makes it ultimately possible for integrating optical camera and

thermal imaging camera through one link.
*The 180ms 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.
Superior Performance
MK15 remote controller carries Qualcomm Snapdragon 8-core CPU, which can
decode 1080p @ 60fps video stream by hardware in both H.264 and H.265 format.
The CPU’s powerful computational performance lowers image transmission and
display latency to 180ms. *Transmitters coming with MK15 enterprise combos are
equipped with standard HDMI port for outputting video stream to an external monitor.
It also supports 4G network, after secondary development the video stream can be
pushed to cloud network.
*Transmitters coming with MK15 agriculture combos do not support HDMI output.
1000 cd/m2 High Brightness, 1920*1080 High-Definition Monitor
MK15 remote controller comes with a 5.5-inch high-definition and high-brightness
LCD screen. Display definition is 1920*1080 pixels. Max brightness is 1000cd/m2,
which is almost two times of usual smartphones, crystal clear under direct sunshine.

Super Long Battery Life, 30W PD Fast Charging
With powerful and big-capacity built-in li-ion batteries, MK15 remote controller’s
battery life is up to 12 hours. The batteries’ stable and efficient discharging curve
secures the system in running in high speed. *MK15 remote controller supports max
30W PD fast charging, which can charge the battery to 95% level in three hours.
*The standard charger coming with all MK15 combos is PD 20W.
