2.Safety Information
WARNING
1. 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.
2. It is prohibited to use the product in a high temperature above 85 °C or in a low
temperature below-45 °C.
3. It is forbidden to disassemble or refit the thermal camera at will.
4. Do not use too long screws when installing the front/rear mounting bracket, which
may damage the thermal camera.
CAUTION
1. No matter 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.
2. Do not use the product under conditions that doesn’t match the environmental
requirements. For specific use environment requirements, see the product parameter
table.
3. Do not apply solvents or equivalent liquids to the camera, the cables, or other
items.
4. Be careful when you clean the infrared lenses. The lens has an anti-reflective
coating which is easily damaged. Damage to the infrared lens can occur with too
much force or cleaning with rough objects such as tissues.

10.Quick Start Guide
Please follow the steps:
1.Install IRT_VMS if the thermal camera is with other networking equipments, and
IRT_TAS_AT can be installed on a single thermal camera for temperature
measurement and analysis. The software may have version updates. Please refer to
the actual version. It is recommended that the computer configuration for installing
the software meet the following conditions:
1.) i5-9500T and above CPU
2. )8G and above memory
3. )64-bit Win10 system,
4.) Main board H370 chip set
5.) Support Gigabit network.
6. )The screen resolution is recommended to be 1920×1080
7.) Video Memory 128MB
8.) Network card RTL8168/8111/8112 Gigabit Ethernet Controller
2.Connect the thermal camera, power supply and computer.
3.Set the computer configurations according to the software instructions for
IRT_VMS_User Manual or IRT_TAS_AT_User Manual, change the IP to
192.168.1.×××.(Do not choose 123 or 29 to avoid connection failure for the same IP
with the camera.
4.Double-click the client icon, enter the correct user name and password, and click
login to start the client.
5.Select the IP on the client homepage, and add the module number you want to
preview to the PC preview interface. If the thermal camera is successfully connected,
you can start imaging and monitoring with the thermal camera.
6.The 232 transmission between the computer and the thermal camera can be
realized through the RS232 interface on the cable.

AT31/61/61P Online Temperature Measurement Thermal Camera User Manual
11
7.The 485 transmission between the thermal camera and the PT can be realized
through the RS485 interface on the cable to control the PT.
8.The ALARMIN interface on the cable can be used to manually input signals to
trigger the alarm.
9.The I/O alarm output of the thermal camera can be realized through the
ALARMOUT interface on the cable. Non-alarm information remains high, and
becomes low when there is alarm information. After the alarm disappears, it will
continue to be maintained for 30 seconds and then return to high level.
10. The client software TAS and VMS are applicable for the thermal camera, which
can realize other functions needed.
The client software TAS can realize the below functions:
Auto focus
Image capture and video recording
Thermographic analysis/secondary analysis
Export recorded infrared data
Set the parameters and alarm information
Update firmware to acquire the new functions
The client software VMS can realize the below functions:
Auto focus
Multiple thermal camera monitoring
Set parameters and alarm information of a certain thermal camera
Get the information in the alarm region

12.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.

12.1 Camera Mounting
12.1.1 Illustrations
12.1.2 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.
12.2 Cable strain relief
In installations where the camera is subject to vibrations or shocks the power cord may need an external
strain relief arrangement to avoid power port failure.
The following pictures show two examples on how cable strain relief of the power cord can be solved.
