Hi. I’m Dean Drako.
Like many of you I am sheltering in place while recording this video.
There is an opportunity for the physical security industry to contribute to the pandemic battle, and develop some powerful tools in preparation for any future epidemics or pandemics.
One promising area is thermal cameras deployed with video management systems and analytics to detect elevated body temperatures and thereby assist with virus containment.
I’d like to share with you 5 points regarding this technology:
NUMBER 1. Elevated temperature screening is not coronavirus screening. Thermal cameras are generally not approved for, nor intended to be used as medical devices. Furthermore, some people who have the virus may not show a fever.
NUMBER 2. Thermal cameras work by creating an image using the infrared spectrum and then correlating it to temperature. A system can either utilize the highest temperature in the image, or use analytics to find faces and measure temperature on the eyes or forehead.
Number 3, Higher accuracy cameras utilize a small calibration unit placed within the camera’s view. In contrast, typical thermal cameras used alone show a baseline accuracy of plus or minus 2 to 4 degrees Fahrenheit which is not considered accurate enough to measure body temperature. Eagle Eye Networks recently tested a solution with a calibration unit and found it accurate to plus or minus *ZERO POINT 4* degrees.
NUMBER 4. Video management systems can utilize analytics to automatically send notifications or generate an alarm when pre-specified temperature points are exceeded. These notifications eliminate the need to have a dedicated attendant constantly monitoring.
AND NUMBER 5. A video management system should include cyber security protection to prevent cameras being used as an attack vector. This is especially important given the current shortage of thermal cameras, and because some advanced temperature screening technologies are only available from Chinese suppliers.
With more focus and development, automatic, non-intrusive, elevated temperature screening can help give peace of mind as we regroup and reengage. It may become common for us to passively screen people who enter a building and ask those with elevated temperature to work from home.
We are extending the Eagle Eye Cloud Video Management Platform to fully support Elevated Body Temperature Screening using multiple different Thermal cameras. We have been testing accuracy while doing this and the results are promising.
