Any object with temperature above absolute zero emits a detectable amount of radiations. Thermal camera converts IR radiations into gray value, and establishes the accurate corresponding relation between gray value and temperature through the temperature measurement algorithm model. The model (Temperature Gray Level Curve) is obtained by black-body calibration.
It is well-known that one major symptom of virus infections is fever. Therefore, thermal camera with high temperature accuracy can detect the elevated body temperature to make the preliminary screening. Thermal cameras are advisable to be installed at the places with long queues such as passport control.
1. High Efficiency: It takes only one second that thermal camera can detect temperature of each person. Thus, no congestion will be made when passing through the site where temperature needs to check.
2. Safety: Thermal camera supports non-contact temperature measurement which can achieve accurately measuring temperature around 1 meter away. That reduces the risk of infection coming from physical contact.
Thermographic fever screening Solution Advantages.
Thermographic fever screening Bullet/Turret cameras provide AI Face Detection function, locate multi faces intelligently and measure the faces only , to reduce false alarm from other heat sources.
Thermographic fever screening Bullet/Turret cameras are able to do onboard audio alarm, notice the operator without the requirement of other sirens , reduce the complexity of whole solution.
thermographic fever screening products are embedded with self-developed algorithm, which specially optimized for temperature measurement thermography. Combined constant temperature/dust-free automated manufacturing process with big data, could ensure the accuracy of thermal cameras
