Pros & Cons: Thermal Imaging Camera vs Gun Thermometer
Since the Covid-19 outbreak, everyone is somehow getting more familiar with the use of non-contact infrared thermometers. Another common tool for non-contact temperature detection widely used in public places is thermal camera also known as thermal imaging scanner. Both gun thermometer and thermal camera have the same working principle; they use infrared technology to detect infrared radiation and translate it into a temperature reading. thermal camera however, has several advantages compared to a gun thermometer:
- Gun thermometer only gives you a number – while a thermal camera generates a temperature reading and image.
- Gun thermometer reads the temperature on one single spot – a thermal camera lets you see the “hotspot” of a bigger area of the body through the thermal image.
- thermal cameras can also detect temperatures from a longer distance because of advanced optics. This supports social distance measures and allows quick inspection especially in areas with high people traffic.
The thermal imaging systems have been shown to measure someone’s skin temperature accurately without any physical contact. During the pandemic, thermal scanners have been used in several countries and have shown certain advantages over gun thermometers to measure temperature. Even though the temperature screening cannot directly detect if someone has COVID-19 or not, it helps to sort out and detect high-risk people with high temperature, given that high temperature is one of the most common symptoms found in most cases.
Pros & Cons
The best advantage of thermal cameras is that the person in charge is not required to make any physical contacts or even stay near to the person being measured.Coronavirus can spread easily among humans, a very quick contact with the infected individual can transmit the diseases. Not having to contact multiple people can help to reduce the risks of disease transmission.
Not only minimizing infection risk of close-distance measuring, using a thermal camera also saves time. Imagine going to the office on Monday morning and having to wait for 20 people in line to get checked with hand-held gun thermometers that must be held at close distance can be a very consuming task especially in areas with high traffic. In addition, it can also cause long lines and social distancing neglection between people waiting in the line.
In terms of price, although it can vary differently between brands, normally thermal cameras cost more than gun thermometers because they have more advanced technology.
I Need Something Better than Gun Thermometer but not as Pricey as Thermal Camera
If you are looking for something that has all the benefit of a thermal camera but just cost you a little bit more than the gun thermometer, then Scarlet SE13 Thermal Imaging Scanner is your best choice.
SE13 Thermal Imaging Scanner is a contact less infrared temperature detector with automatic visual (Red/Green LED Light) & audible alarms designed as an initial fever screening tool at entrances of small-to-medium public places. SE13 has smart pre-set black body calibration with +/-0.3°C high accuracy, low power consumption, user-friendly UI, and instance reading display on 2.4” color TFT Screen.
SE13 is currently the only one of its kind available in the market. It is designed and engineered to fill the gap and meet the needs of those in between gun thermometer and thermal cameras.

What is Heat Stress?
Heat stress is the effect that the thermal environment has on a person’s ability to maintain a normal body temperature. Physical work generates heat in the body which must be lost to the environment through sweating and evaporation. A hot or humid environment makes this more difficult and this can affect both mental and physical performance. Inability to get rid of body heat adequately may result in heat illness.
Workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Exposure to extreme heat can result in occupational illnesses and injuries. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes.
