Infrared thermal imaging system has played a very important role in the fight against Covid-19.In the use process,still need to pay attention to some details in order to make the device to get twice the result with half the effort.

First of all,if the entrance and exit of the pedestrian passageway is wide,multiple infrared thermal imaging systems should be installed,otherwise people with abnormal body temperature will miss the net.The width range that can be monitored by one device is limited-generally 2.5m.If the width of the inlet and outlet exceeds this range,multiple devices should be considered to monitor all passing personnel.

Second,pay attention to the ambient temperature of the use scene.If necessary,the temperature difference compensation can be set in the system.Infrared thermal imaging systems are generally used indoors,but in some places with harsh environmental temperatures,such as equatorial or arctic countries,the system parameters must be adjusted to compensate for the temperature deviation caused by the environment.

Attention should also be paid to ambient light when using infrared thermal imaging systems.If the ambient light is too weak,the camera will fail to capture the face ,and the body temperature will not be detected.The filling light can be turned on in the system,and the period of opening of the filling light can be set to make up for the impact caused by insufficient light.
