Thermal Fever Screening Camera Solutions and products in Bangladesh
Principle
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.
Application
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.
Advantages
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.
Thermal Fever Screening Process
Set up a quick channel: Set up a quick screening channel in the indoor space to separate space into few parts.
Thermal camera quick screening: Using thermal fever screening solutions to do quick screening of moving crowd and ensure the efficiency
Thermometer secondary check: For the person who is doubt fever symptoms, using thermometer to do secondary check is necessary.
Applications areas:
✓ Hospital ✓ Market ✓ Railway stations
✓ Enterprise ✓ Station ✓ School
✓ Airport ✓ Apartment buildings ✓ Place of crowded flow
✓ Place of high risk ✓ Entrance security check ✓ Temporary control

FAQ
Q: Can the thermographic fever screening camera be installed outdoors?
A: Outdoor wind and sun can easily affect the body surface temperature and the working status of the camera, which results in a deviation between the measured body surface temperature and the actual body temperature. From the perspective of ensure the accuracy, we strongly recommended the solutions used indoors.
Q: Does the camera recognize the face for temperature measurement
A: The camera recognizes faces when screening. It supports up to 30 faces. But still we recommended to carry out temperature measurement in order.
Q: Can the accuracy of thermographic fever screening camera reach 0.1 ℃?
A: No. At present, cameras with accuracy higher than 0.5 require black-body online real-time calibration and intelligent compensation. The accuracy of black body is currently plus or minus 0.2, and it is impossible to achieve 0.1. High-precision accuracy solutions right now are all 0.3
Q: Will other heat sources (such as tea cups, kettles, etc.) cause false alarms?
A: The cameras are able to use face recognition technology, so other heat sources will not cause false alarms.
Q: How long can I use the fever screening function after the camera is turned on?
A: 5 minutes after the handheld camera is turned on, 30 minutes after the bullet / turret camera is turned on.
Q: What is black body? What should be noticed before purchase black body?
A: The black body is a standard temperature source; the thermographic cameras are able to calibrated based on the temperature of the black body.
The black body only needs to be powered; no internet required.
Hikvision thermal cameras are available with a black body to increase accuracy.
Currently black body only supports Chinese power supply standards. And no overseas certification.
Q：Is thermographic handheld camera support alarm automatically? Or is it support link with VMS
A: Thermographic handheld camera support value character turns red automatically when detect temperature-exception, but no other method to notice. Not support link with VMS
