Gimbal
Hover 2 uses an integrated two-axis gimbal camera, combined with EIS
technology, to shoot high-quality and stable images during the flight. The
gimbal's tilt control range is -90 ° to + 22 °. During the shooting, the gimbal's
control wheel can be used to adjust the gimbal's tilt angle.
Camera
The camera has a 1/2.3" CMOS and the effective pixels is 12MP. The camera
shoots up to 4k video and 12 MP photo, and supports shooting modes such as
single shot and self-timer shooting. Camera shots can be previewed in real time
through the App or Palm Pilot.
Camera storage
The drone has internal 3GB storage space and is equipped with a microSD card
slot to support external microSD cards. When the drone detects that a microSD
card is inserted, the videos and pictures will be stored on the SD card
preferentially.
Tips：
1. After the drone is turned on, please place the drone horizontally and make sure that
no foreign objects get stuck in the gimbal, otherwise the temperature of the gimbal
may be too high and the camera may be damaged.
2. During the use of the drone, please avoid the collision of the gimbal camera.
3. Flying in a low temperature, foggy, sandy environment may cause the gimbal
abnormal. Please choose a suitable flying environment.

6
Optical Radar
Hover 2 is equipped with an original rotary vision radar system, combined with
advanced obstacle avoidance algorithms such as SLAM (instant positioning and
map construction), VIO (visual inertial odometer), and path planning, which can
detect the surrounding environment during flight and achieve 360-degree
obstacle avoidance in real time. During the flight, the optical radar will
automatically rotate and adjust the detection direction according to the flight
behavior. The detection distance can reach 10m.
After popping up the optical radar, it will automatically detect obstacles during
the flight to help the drone avoid obstacles. Please note that the detection range
of the optical radar is limited. If the obstacle is outside of the detection range, the
drone cannot automatically avoid it. Please fly with caution.
Obstacle Avoidance
Obstacle avoidance requires the optical radar and the switch of obstacle
avoidance to be both turned on. If one of them is closed, obstacle avoidance will
not work. You can see the switch of the obstacle avoidance on App or Palm Pilot.
If the obstacle avoidance works, the drone will automatically hover and wait for
the user to operate when detected an obstacle.
In Omni-Follow mode, the drone will try to fly over the obstacles;
During the returning, the drone will try to fly over the obstacles and then
continue to return.
Tips：
1. Please note that the earlier drone firmware only supports obstacle avoidance in
Manual Control mode. The drone cannot avoid obstacles in the Omni-Follow, TrackShots
mode and process of return to home. Please fly carefully!
2. To ensure a good flight experience, please turn on the optical radar and switch on the
obstacle avoidance before flying.
3. If the lighting conditions are not satisfied, for example, the light is too strong or too
dark, the optical radar cannot detect obstacles;
4. Optical radar cannot detect small or transparent obstacles, such as kite lines, glass,
etc. Please pay attention to avoid;
5. Please use and turn off the optical radar correctly to avoid collision and keep the lens
clean;
6. Please avoid using the optical radar in sand, dust and rain.
