Safety Information
WARNING
- Before using the cleanser, make sure you read all applicable material safety datasheets (MSDS) and warning labels on cleanser containers.
- Do not use too long screws when installing the front/rear mounting bracket, whichmay damage the thermal camera.
- It is prohibited to place the product in a high temperature above 70°C or in a lowtemperature below-45 °C.
- It is forbidden to disassemble or refit the infrared thermal camera at will.
CAUTION
- 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.
- Do not use the product under conditions that doesn’t match the environmental requirements. For specific use environment requirements, see the product parameter table.
- Do not apply solvents or equivalent liquids to the camera, the cables, or other items.
- 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.
Notice to user
Calibration
Annual calibration to the thermal camera is recommended to ensure the accuracy of temperaturemeasurement, either through IRAY TECHNOLOGY or third-party organizations.
Accuracy
For accurate measurement, it’s recommended that you use the thermal camera after it is stablefor 30minutes.

Quick Start Guide
Please follow the steps:
- 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 supplymethods for AT20. Connect the device to the PoE port of the power supply throughthe M12 8-pin adapter cable or connect to the DC power supply through the M1212-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.
- 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 SharingCenter”-“Change Adapter Options”-“Ethernet”-” Properties”-“Internet Protocol Version 4 (TCP/IPv4)” – “Use the following IP address”-set the IP address to192.168.1.xxx.
- After the power is on for 30 minutes, the temperature measurement, monitoringand analysis can be carried out through the web terminal of the computer. For webinstructions, please refer to AT20 Online Dual-spectrum Thermal Camera WebClient Operation Manual.
