Warning
Please read the instruction carefully before install and use this product, and keep it in a safe place.
Observe all warning operating instructions, and follow all operating instructions;
Do not allow the supply voltage to exceed the specified range;
Do not allow the the use environment beyond the environment condition of the pod;
Do not make the camera's thermal imager to look directly at high-intensity radiation sources such as the
sun, carbon dioxide lasers, and electric welders（including power on or off（, in order to avoid damage to the
focal plane of pod;
All loads(include SSD) are protected from static electricity during use to avoid damage;
Pay attention to the protection of the internal interconnection and the external connection cable;
There are no user-serviceable parts inside the pod. Do not open the pod without the company permission,
or the consequences are the responsibility of the user;
Disconnect the power supply before cleaning the pod. Do not use chemical solvents, thinners, or spray
cleaners.
（· Ensure that the interface definition on the airborne side is correct;
（· Ensure that the supply voltage in the given range（3S~6S.

Device Introduction
Foxtech Bi-Focus is a 2-axis high stabilized gimbal with a 10X optical zoom camera and a 320x240 thermal
camera. Foxtech Bi-Focus has a small volume and light weight. The high precision 2-axis gimbal is based
on FOC technology, which features high stability, accuracy and sensitivity.
Foxtech Bi-Focus is a functional camera and gimbal, supports 1080P 60fps video output, and 4 mega
effective pixels. The resolution of thermal camera is 320*240. Dual sensors help pilot easily collect visible
and thermal imaging data of the same picture in one flight. Bi-Focus supports dual-channel synchronous
video recording, which is convenient for subsequent video analysis.
Bi-Focus supports multiple thermal imaging pseudo-color pattern, can switch from one pattern to another,
and has temperature measuring and picture-in-picture function. Foxtech Bi-Focus supports Sbus control,
supports TF card storage.
The structure of the gimbal:
Bi-Focus can be applied in fire fighting and searching, rescue,power line inspection, crop protection etc.

Technical Characteristics
The device consists of a thermal movement, a zoom visible light movement, and a stabilized gimbal. The
visible and thermal video streams are stored separately in the visible light movement, and synthesize
multiple picture-in-picture modes according to external control commands and output by HDMI.
