1 INTRODUCTION
1.1 Product Features
AI Smart Identify and Tracking
A8 mini gimbal camera carries a neural network processing unit (NPU), embedded
in brand-new AI algorithms developed by SIYI. A8 mini can autonomously identify
moving objects like vehicles, boats, and people. Companion with gimbal rotation
and UAV flight control system, the gimbal camera will accomplish an overall smart
operation from identifying and locating to continuously tracking. A8 mini’s zoom
camera will always maintain the tracking object in the center of the image.
*The AI feature is under development and will be supported by firmware update soon.
Powerful Imaging System
A8 mini gimbal camera comes with a 1/1.7-inch Sony image sensor, a megapixels
CMOS with remarkable photosensitivity ability, impressive 4K video recording, and
smooth 6X digital zooming. Those combined features make distant beautiful
sceneries nicely seen in motion pictures.
Upside Down Mode
A8 mini gimbal camera automatically activates upside down mode when it is placed
upside down, very convenient to be mounted on multiple kinds of vehicles like UGV,
USV, robot dog, and robotics.

Various Video Output, Ultra Low Latency
A8 mini gimbal camera provides triple popular video output options, Ethernet, HDMI,
and CVBS (AV). RC plane and FPV drone users can experience very low latency
FPV through CVBS video output and analog image transmission system.
*A8 mini configured as ultra-low-latency mode, CVBS output to analog FPV transmitter, view from
the monitor connected to FPV receiver, the overall latency is 60ms. Direct HDMI output from A8
mini to monitor, the latency is 65ms.
Gimbal Motion Mode
FPV Mode
Gimbal rotates simultaneously as aircraft rolls to get FPV view, and output
enhanced stable images, compatible with planes and racing drones especially for
FPV scenes.
Follow Mode
Horizontally, gimbal follows when aircraft rotates, compatible with multi-copter
drones.
Lock Mode
Horizontally, gimbal does not follow when aircraft rotates.
Starlight Night Vision Camera
A8 mini gimbal camera’s 1/1.7-inch ultra-sensitive starlight CMOS can keep image
bright even in low light environment. HDR feature can precisely capture details of
highlights and shadows in dynamic scenes, getting away of low light or backlight.

3-Axis Gimbal Stabilizing Control Algorithms
High-Precision FOC Motor Control
A8 mini gimbal camera is applied with industry-level 3-axis stabilizing technology
and high-precision FOC control algorithms, which reduces most image shaking and
ensure image is always stable even if aircraft or vehicle is vigorously moving.
Meanwhile, camera continuously outputs smooth and clear images even in zooming.
