Solution for detection of people with fever
What is a thermal camera?
A thermal camera is a device that forms images visible to the human eye by detecting infrared emissions produced by the electromagnetic spectrum of a body. It operates with the wavelength located in the thermal infrared zone.
In other words, a thermal camera allows you to see on the screen the heat radiation emitted by an object, animal or person, although we cannot see them with the naked eye.
What margin of error do they have?
Temperature analysis for people has a margin of error of just 0.3
How do thermal imaging cameras work?
To understand the operation of such a camera, it must be borne in mind that all objects emit infrared radiation, which is greater the higher the body temperature. Our eyes cannot see these emissions because their range in the electromagnetic spectrum is between visible light and microwave radiation.
In order to build thermal images based on captured infrared radiation, an infrared camera has sensors that detect heat and performs a thermogram or temperature pattern, which is sent to a processor.
Thermal sensors used in these types of devices can be passive and active. The former are limited to detecting the heat emitted by an object. Instead, active sensors go further and heat the object's surface to better collect information about its temperature.
These are very sensitive elements that need direct visual contact with the element for its correct operation. Apart from surveillance, they can be used in other areas such as the military or vehicle construction.
Applications of thermal imaging
A thermal camera can be used in many fields and its applications increase day by day, as its technology evolves. Some of the most important are worth noting:
Used to detect fever in people, it is a great help to make an admission filter for large places such as: casinos, bingos, airports, port terminals, etc.
At an industrial level, the possibility of creating thermal images allows detecting friction in motors, heating of electrical components, leaks, obstructions, overloads or levels in tanks, among other situations.
Similarly, thermal imaging cameras are used in construction to check the energy efficiency of a building and the distribution of temperatures in heating systems. They are also a good option to signal the existence of heat leaks, humidity or leaks in a structure.
Of course, thermal cameras are also applied in security and research, the detection of fire sources is one of its most common uses in this area, as well as the establishment of security perimeters.
Advantages of thermal cameras for companies
Conventional cameras are very efficient during the day and in the most conventional situations. On the other hand, at night or in areas that prevent correct visibility, they do not guarantee total security.
Being able to have quality thermal images represents a plus of protection for any company, since infrared cameras allow detecting everything that cannot be seen with the naked eye, whatever the lighting conditions of a given space. Therefore, with these devices a company can better monetize its investment in security systems, control false alarms and overcome detection problems of any type of object due to lack of light or visual limitations of any kind.
In all these cases, the application of a video analytics system is recommended so that companies can optimize their work with the images obtained with this type of thermal camera.
Features of professional thermal cameras
When choosing a thermal imager for professional use, it is important to take into account the following characteristics:
Robustness and build quality.
Have adjustable focus to get better quality images.
The combination of visible and infrared light helps quickly locate potential security problems.
Have advanced software for image enhancement and diagnostic reporting.
Following the problem of (COVID - 19) we are providing personalized advice since each case requires a suitable solution such as places where there are multiple entries where more complex control is required and also according to each place, an analysis must be carried out to see which of the camera variants is recommended taking into account the flow of people, the location of the camera, etc.
