Application of Infrared Camera in Mobile Body Temperature Detection and Character Recognition

Nov. 15, 2023

Since the outbreak of the COVID-19 pandemic, there has been a significant shortage of tools for human temperature measurement, especially devices capable of simultaneously detecting the temperatures of multiple individuals on a large scale. Through research and development, infrared cameras capable of simultaneously measuring the temperatures of multiple people and supporting the detection of moving targets have become crucial tools in temperature screening, widely used in areas with large-scale movement of people.

Working Principle:

Infrared cameras measure the infrared radiation emitted by objects to obtain temperature information, providing a unique advantage in temperature detection. Even for temperature detection in moving crowds, infrared camera technology can real-time, remotely, and non-contact measure the surface temperatures of multiple individuals, swiftly identifying those with abnormal temperatures.

Infrared Thermal Imaging Camera


  • Non-contact Detection: Infrared camera technology eliminates the need for contact with the individuals being measured, thus avoiding the risk of cross-infection present in traditional temperature detection methods.

  • Real-time Monitoring: Infrared cameras can capture and record the temperature changes of moving individuals in real-time, aiding in the prompt identification of abnormal situations.

  • Large-scale Application: Effective for large-scale temperature monitoring in crowded places such as airports, stations, and shopping malls, enhancing detection efficiency.

  • Person Recognition: Through the analysis of unique infrared features of the human body, infrared cameras facilitate effective person recognition, contributing to security surveillance and personnel management.

  • Low-light Conditions/Night: Infrared cameras utilize starlight-grade security camera night vision mode, allowing clear observation of crowds and surrounding environments even in poorly lit nights, improving screening efficiency.

  • Privacy Protection: Infrared cameras focus on identifying individuals with abnormal temperatures and leave a real-time thumbnail. This information is not stored on the server, only recorded on the monitoring computer, and can be configured to not record any personal information, enhancing privacy protection.

  • Adaptation to Complex Environments: Infrared cameras exhibit strong adaptability to natural conditions such as light, rain, and snow, making them suitable for various environments.

  • Rapid Measurement: Simultaneous temperature measurement of 20 people takes only 0.3 seconds, with a measurement distance of 1-2 meters and an accuracy of less than 0.3 degrees Celsius.

  • Wide Temperature Measurement Range: Temperature measurement range from -15°C to 150°C, supporting color marking for temperature anomalies.
