2. Safety Information
WARNING
Before using the cleanser, make sure you read all applicable material safety
data sheets (SDS) and warning labels on cleanser containers.
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 place the product in a high temperature above 70°C or in a low
temperature below-45 °C.
WARNING
It is forbidden to disassemble or refit the infrared thermal camera at will.
CAUTION
No matter if there is a lens cover, do not point the 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.

AT20 Online Dual-spectrum Thermal Camera User Manual

CAUTION
Never apply cleaning solutions or similar liquids directly to the thermal camera,
cables, or other components.
CAUTION
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.

3. Notice to User
3.1 Calibration
Annual calibration to the thermal camera is recommended to ensure
the accuracy of temperature measurement, either through IRAY
TECHNOLOGY or third-party organizations.
3.2 Accuracy
For accurate measurement, it’s recommended that you use the
thermal camera after it is stable for 30 minutes.
3.3 Video Teaching
You can search for mount and use videos from our website.
3.4 Documentation Update
Our manuals are updated several times per year, and we also issue
product-critical notifications of changes on a regular basis. Please
visit our website to access the latest manuals and notifications.

6. Quick Start Guide
1. After installing the thermal camera in the desired position, use the
cable to connect the thermal camera and the computer normally.
There are two power supply methods for AT20. Connect the device to
the PoE port of the power supply through the M12 8-pin adapter cable
or connect to the DC power supply through the M12 12-pin adapter
cable. Connect AT20 to the network, and wait for 2 minutes after
powering on. The power indicator light is steady blue and the network
indicator light flashes green, indicating that the network connection is
normal.
2. Modify the computer network segment to be the same with that of
thermal camera. The specific path is "Control Panel"-"Network and
Internet"-"Network and Sharing Center"-"Change Adapter
Options"-"Ethernet"-" Properties"-"Internet Protocol Version 4
(TCP/IPv4)" - "Use the following IP address"-set the IP address to
192.168.1.xxx.
3. After the power is on for 30 minutes, the temperature measurement,
monitoring and analysis can be carried out through the web terminal
of the computer. For web instructions, please refer to AT20 Online
Dual-spectrum Thermal Camera Web Client Operation Manual.

8. Mechanical Installation
The front and back of the thermal camera are equipped with
mounting interfaces, which can be installed with screws after the
holes are punched with the auxiliary stickers in the package. In
addition, we also provide two optional forms of front and back
installation.
WARNING
Do not use too long screws in case of damaging the thermal camera. The
maximum hole depth of the front shell is 10mm, and the maximum hole depth
of the rear shell is 4mm.
It’s normal that the thermal camera will generate heat during
operation. In order to sufficiently dissipate the heat, it is suggested
that the back shell of the thermal camera should be fixed on a metal
object to minimize the temperature drift of the infrared detector in
thermal camera.
8.1 Installing Shells with Screws
8.1.1 Installing Front Shell
As shown in Figure 8.1, please paste the sticker to the position to be
installed, and then punch 4 Φ2.5 mounting holes according to the

label on the sticker, and use 4 ST2.2 screws to install the front shell.
Figure 8.1 Front Shell Installation
8.1.2 Installing Rear Shell
As shown in Figure 8.2, please paste the sticker to the position to
be installed, and then punch 4 Φ2.5 mounting holes according to
