WARNING
Make sure you read all applicable Material Safety Data Sheets (SDS) and warning labels on
containers before you use a liquid. The liquids can be dangerous. Injury to persons can occur.
WARNING
Do not use too long screws when installing the front/rear mounting bracket, which may damage
the thermal camera.
WARNING
It is prohibited to use the product in a high temperature above 85 °C or in a low temperature
below -45 °C.
WARNING
It is forbidden to disassemble or refit the thermal camera at will.
CAUTION
No matter if there is a lens cover or not, do not point the infrared thermal camera towards
strong light or equipment with laser radiation. This will affect the accuracy of the thermal
camera and even damage the detector in the thermal camera.
CAUTION
Do not use the product under conditions that doesn’t match the environmental requirements.
For specific use environment requirements, see the product parameter table.
CAUTION
Do not apply solvents or equivalent liquids to the camera, the cables, or other items.
CAUTION

11. Mechanical Installation
The thermal camera can be mounted via a transfer bracket with four metric M2
mounting holes at the bottom of the mounting interface.
WARNING
Do not use screws longer than 3.5mm that will damage the thermal camera.
The temperature rise will occur during normal operation. If the thermal camera is
used under poor heat dissipation conditions, the temperature rise may be too high,
which will affect the temperature measurement performance. In order to ensure the
normal use of the thermal camera, it is recommended to be used under good heat
dissipation conditions.

11.1.2 Explanations
1. Fix the thermal camera at the desired location according to the specific use
method. The recommended location is in a sheltered area with a relatively
stable thermal state.
2. Connect the power cable to the power adapter and interface 1 respectively,
power on the thermal camera, and connect the two ends of the network cable
to interface 2 and the PC Gigabit Ethernet port respectively.
3. Wait 30 minutes after you have stated the camera, then the temperature can
be measured and analyzed by the client software of the computer.
