Gimbal introduction
uses professional three axis stabilized zoom gimbal,
adopt high precision encoder FOC control scheme, mount 12
times optical zoom, 1080p Full HD night vision network camera,
Realize long-distance zoom night aerial photography in the air,
designed for public security, fire protection, electricity, etc.
Gimbal characteristics:
1)The speed of gimbal is adjustable: At large times of the
camera,adjust to slow speed,control is more accurate ;and at
small times of the camera, use fast speed, control is more
sensitive and faster.
2)The function of one button back to home position: return
initial position automatically and rapidly by one button.
3)Support PWM control and serial command control, suit for
close distance remote control or remote data transferring
command control gimbal and camera.

Object tracking function(optional)
-2-
1 
Build-in normalization ,cross-correlation and tracking algorithm,
combining with object missing recapture algorithm, achieve stable
track of the target.
Support custom characters of user OSD, adaptive gate, cross
cursor,trace information display.
2、Tracking performance
1)Update rate of deviation pixel 50Hz
2)Output delay of deviation pixel <15ms
3)Minimum target contrast 5%
4)the minimal signal-to-noise ratio ( SNR) 4
5)Minimum target size 16*16 pixel
6)Maximum target size 160*160 pixel
7)Tracking speed 32 pixel/frame
8)The mean square root values of pulse noise in the target
position<0.5 pixel

1、Camera control line
Zoom: camera zoom control line, connect
PWM receiver on third gear, or rocker.
Focus: camera manual focus control line,
connect receiver on third gear, or rocker. If

automatically after zooming.
P i c / R e c : p h o t o g r a p h y / v i d e o , m o d e
switching, video and photography control,
connect receiver on third gear.
Switch to high:
Start video, REC ON display
Switch to middle :
Stop recording, STBY display
Switch to low: Take photos, SNAP display
Multi: Night view mode on / off, Laser on / off
Switch from middle to high: camera night feel infrared mode (black and white mode)
Switch from middle to high again: Camera color mode
Switch from middle to low; Turn on the laser in the camera night sensitive infrared
mode(pay special attention to safety!!! High-power laser
You can't look straight into your eyes, or face consequence!!!)
Switch from middle to low again :Turn off the laser
AV: analog output signal

Functional descriptions of mode (regard the third switch channel mode as the example)
GImbal PWM signal instructions:
YAW directional channel: speed mode ,connect rocker channel, (or third
gear switch channel, stopping need third gear to middle position.）
PITCH Pitch channel：speed mode ,connect rocker channel, (or third
gear switch channel, stopping need third gear to middle position.）
MODE gimbal one button back and speed adjustment：angle mode, A
knob or a thirt gear channel switch.
Turn the knob to the three position: Low speed & not follow yaw mode, at this
moment, the joystick controls YAW and PITCH, gimbal has the lowest speed of
movement, its yaw does not follow the rotation of the aircraft；
Turn the knob to any position above three:variable speed & following mode,
at this moment, the joystick controls YAW and PITCH, The movement speed of
gimbal rises(Speed varies with position) ,gimbal works in follow yaw mode.
Turn the knob to the one position : gimbal returns to the home position;
Toggle switches one time between position -2 and -1 rapidly, gimbal returns to
the home position;
Toggle switches two times between position -2 and -1, gimbal use speed mode
(profile 1)
Toggle switches three times between position -2 and -1, gimbal use angle mode
(profile 2);
Toggle switches four times between position -2 and -1, calibrate the accelerator.
Toggle switches five times between position -2 and -1, calibrate the gyroscope
Note: GImbal turns on in the static state, and the gyroscope is automatically
calibrated ;The working mode of gImbal at the next boot time is the mode used
last time, factory mode is speed mode.
