If you are thinking about strengthen protection of your company or home, you have surely wondered what it is and how to choose the best model. The market is full of interesting alternatives. And yes, among them one of the most popular is thermal camera . Do you know her?
The point is that, beyond deciding whether or not to install these systems, the complicated thing ends up being choosing which one is going to be placed .
- Team infrared or Team Microwave sensors, which alarm team are you on?
The data protection law allows the use of this type of device as long as it is properly informed with a visible sign , but the really complicated thing is usually deciding which one to install among so many alternatives on the market.
What is a thermal camera
You don't have to be a lynx. From the name you already know that this type of cameras are related to temperature. Yes, a thermal camera is one thatemits infrared rays that allow temperature detectionof objects in your field of vision.
They work with what is known as " thermography infrared ". This is a technique through which you can visualize the temperature field of the surface of an object or a person. In this way,an image is created with cool and warm colors based on the heat detected.
Thermal cameras, thanks to this new technology, capture the heat given off by the objects that appear in the scene being recorded. The result is what is known asthermogram or infrared image.
What is a thermal camera for?
What is the use of capturing temperature and what does that have to do with safety? Like any other type of video surveillance system, one of the functions of thermal cameras is to detect the presence of intruders in our facilities, among other things.
In companies, their use has become very widespread lately. But what advantage do they offer over traditional cameras? Well, they are a great optionif environmental conditions require it.
Think, for example, of an industrial warehouse located in an open field, where there are elements that hinder visibility: foliage, smoke, dust or even fog.
In these cases, thermal vision is much more useful than conventional vision, as it will allow detect the presence of a person in spaces where the traditional camera could not.
On the other hand, they are also a very effective methodif the perimeter we need to monitor is too large to have it fully illuminated. In dark areas, normal video surveillance cameras would not work, so a thermal camera would be an ideal choice.
However, not everything related to security has to do with preventing theft. These types of cameras also have many uses when it comes to safety of people . We clearly could with the COVID-19 pandemic.
Thermal cameras were used in many spacesto measure people's body temperature, especially in large areas such as train stations, airports, or very large companies where hundreds of workers passed through each day.
Measuring the temperature of spaces is also practical forprevent accidents in production lines. Detecting a high temperature at a certain point helps avoid incidents, short circuits, fires, etc.
How to choose the best thermal camera
Now that you know What are thermal cameras and what are their functions? , we are going to explain to you what characteristics you have to consider to choose the option that best suits your needs.
- Manufacturing material : This does not usually affect the quality of temperature measurement, but if you are going to place the camera outdoors, or indoors where it is concentrated very hot , you must choose a model made with resistant material .
- Measuring range : Typically these cameras detect between 40 and 320 degrees. However, there are higher range models that capture much more temperature. The midranges reach 650 degrees, and the professionals 1500 °C . Keep in mind the greater the range, the greater the precision.
- Compatibility : Although it may seem obvious, do not buy any camera before you have checked its compatibility, especially to accurately reproduce the images captured.
- Scope : Make sure it has good visibility long distance .
- Storage capacity : Nowadays, many thermal cameras not only have internal storage via SD cards, but also integrate advanced options such as cloud storage or connectivity with remote servers.
- Sensitivity : That its operation is correct even in the darker spaces .
- Resolution : The basic ranges have 80x60 and 120x90 pixels. The mid-ranges, with 160x120, 220x165 and 240x180 pixels. And, the professional ranges, with 260x195, 320x240, 640x480 or even 1024x768 pixels . The higher the resolution, of course, the higher the price usually is.
- Price : There are models on the market for just over 50 euros. Although the price is always decisive, since it will have to fit your budget, do not make the decision based on the cheapest option, since you may end up purchasing a product that does not fit your needs.
Come on, if you have a business located in an environment with poor visibility, or you need a device that measures temperature for security reasons, thermal cameras are the ideal security option.
