The customs airport thermal imaging scanner is a type of security inspection device commonly used at airports and customs, aimed at detecting the body surface temperature of individuals for screening potential fever patients, especially during outbreaks of large-scale infectious diseases or epidemics. Here are some basic information about the customs airport thermal imaging scanner:
Principle: The thermal imaging scanner uses infrared thermography to measure the temperature of the body surface. Every object emits infrared radiation, the intensity of which is related to the object's temperature. The thermal imaging device can capture these infrared radiations and create thermal images based on temperature differences.
Operation: When people pass through the thermal imaging scanner, the device scans their facial or body surface temperature. If someone's body temperature exceeds the preset threshold, the system will sound an alarm for further inspection.
Application: This type of scanner is commonly used for detecting fever patients, which is particularly important during outbreaks or epidemics, such as during the COVID-19 pandemic. Through rapid screening, potential infected individuals can be identified and further measures can be taken, such as isolation or more detailed medical examinations.
Accuracy: Thermal imaging scanners have a certain level of accuracy in detecting fever patients, but they are not absolutely accurate. There are many factors that can affect the accuracy of temperature measurements, including ambient temperature, the way the device is used, and individual differences. Therefore, they are typically used as preliminary screening tools and further examinations are needed to confirm the diagnosis.
Privacy and Ethical Considerations: When using thermal imaging scanners, it is important to consider privacy and ethical issues. Collecting people's body temperature data may involve personal privacy, so it is necessary to handle and store these data with caution to ensure compliance with laws, regulations, and ethical standards.
The customs airport thermal imaging scanner is a useful tool for screening potential fever patients, but they should not be considered as absolute diagnostic tools but rather as part of initial screening. Additionally, privacy and ethical issues should be handled with care when using these devices.
