Recently, the need for temperature monitoring has gained prominence due to COVID-19, making the use of temperature measurement equipment at the entrances of commercial establishments mandatory as a safety measure. This process has amplified the discussion on the use of video monitoring equipment to enhance access control in establishments.
However, there are specific characteristics for each type of CCTV equipment, and nowadays it is possible to find extensive catalogs with hundreds of types of cameras in their various versions.
As we saw in the following article, thermal cameras are responsible for a significant amount of searches related to security and prevention against COVID-19, but they may not necessarily be ideal for temperature measurement. Below is a comparison between thermal, thermal imaging, and infrared sensor cameras.
Infrared Sensor
Cameras with infrared sensors are commonly found in the CCTV market and are generally produced with a sensor that works in conjunction with a standard image capture lens. Infrared sensors help capture images in low-light or no-light environments by detecting the infrared light emitted by objects and people.
Thermal Cameras
Thermal cameras are highly technological devices capable of detecting heat in objects, people, animals, etc. For this reason, most of these devices can only be sold with a Registration Certificate (CR) issued by the army. Thermal cameras are generally used for perimeter protection and long-distance motion detection. There are some models that can be sold without the need for a CR; click on this article to learn more.
Thermal Imaging Cameras
Unlike the two types of cameras mentioned above, thermal imaging cameras are generally used specifically for temperature measurement. Although the heat capture systems of these devices are similar to those of thermal cameras, thermal imaging cameras typically have a shorter monitoring range and a more calibrated sensor for short-distance measurement, thus providing a more accurate temperature reading.
