How Thermal Imaging Works
In hopes of helping to prevent the spread of the Coronavirus (COVID-19), many institutions have begun to institute thermal imaging cameras as a pre-screening device. This device identifies elevated body temperature (EBT) which could be indicative of a fever (one of the symptoms of a viral infection). While these are not medical devices and do not replace conventional medical testing, they can be used to give an early indication when used properly.
A special lens focuses the infrared light emitted by all of the objects in view. The focused light is scanned by a phased array of infrared-detector elements. The detector elements create a very detailed temperature pattern called a thermogram.
In any thermogram, the brighter colors (red, orange, and yellow) indicate warmer temperatures (more heat and infrared radiation emitted) while the purples and dark blue/black indicate cooler temperatures (less heat and infrared radiation emitted).
- Can this scan more than one person at a time and differentiate them?
- Does an employee need to stand by and watch the monitor?
No, it can be set up for text alerts to a smartphone.
- Would this be suitable for a small business, place of worship, or a daycare center? Or are they geared more for airports or venues with larger crowds?
This is a great addition to any business that is looking to keep its employees and customers safe.
