A thermal camera is particularly suitable for
Securing the perimeter
Protection against fire
The latest shot at the strain in thermal cameras are bi-spectrum cameras. These are cameras that practically consist of two cameras in one. They have both a visual lens and a thermal lens and a separate image sensor for each lens. This means that you have both a "normal" visual image and a thermal image. The images can be displayed individually or on top of each other as "picture in picture".

That's why you should choose a thermal camera!
A thermal surveillance camera can see incredibly far and is therefore suitable for securing large, open areas. A thermal camera is therefore also much better at sorting out uninteresting image changes (also called false alarms). Unlike conventional cameras, thermal cameras do not see shadows from people, light from car headlights and the like.
Most models are packed with analysis and can therefore be a good help to automatically notify your phone, email, computer or an alarm system.
Protection against fire
Since thermal surveillance cameras can see thermal radiation (heat radiation), the camera is ingenious at spotting heat generation. The camera can therefore help to detect a fire very early - often before conventional fire alarm systems. The camera should not be seen as a replacement for a real automatic fire alarm, but as a good supplement.
A thermal camera can tell with quite great accuracy what the temperature is, in selected areas, in the image. This means that you can get an alarm if the temperature deviates from what you want.
Get temperature alarm at:
- Too high temperature
- Too low temperature
- Too big difference in temperature between two points
You can also choose the cameras to color areas that reach a certain temperature. It could, for example. be an electrical panel or the like.
All objects with a temperature above the absolute zero point (that is -273 degrees) emit infrared radiation. The human eye cannot see and capture the rays, but a thermal camera can.
A thermal camera consists, among other things, of a detector that is sensitive to the infrared radiation. The detector absorbs the radiation and converts it into an electrical signal, which it then gives a color.
This is how a thermal camera works at night compared to the day
Another clear advantage is at night, where thermal cameras often look even better than during the day, as the surroundings are typically a little colder than during the day. Therefore, you will typically not be able to see the difference between day and night on a thermal camera, except that the ambient temperature will be colder at night. It is always the surface temperature of the objects that is measured.
Be aware that surfaces that are highly reflective may reflect the thermal radiation from other sources.
Where are thermal cameras used?
In the past, it was only airports, prisons, military etc. who could afford thermal protection. But prices have dropped a lot over the last 10 years and today have become available to many more people. That is why today you see thermal video surveillance in places like ...
- Airports, railways, ports and similar heavy industry.
- Larger companies, such as factories, for both fire protection, temperature monitoring and perimeter protection.
- Medium-sized companies, such as car dealers, department stores, DIY stores, for perimeter security of outdoor areas.
- Small businesses, such as mechanics, carpenters or shops, for perimeter security of backyards.
- Private security, where only the best is good enough.
Thermal cameras are used most effectively in large open areas, but can also easily see into complex environments.
How far away can a thermal camera spot people?
We have cameras in our showroom that can spot people at a distance of seven kilometers, and detect cars that are up to 20 kilometers away. But it is the few who are willing to spend 900,000 DKK excl. VAT on a thermal camera: D

Corona (COVID-19) and thermal camera
The global corona pandemic, which has left a huge imprint on the entire world by 2020, has seriously opened the eyes of the world to the possibilities of thermal cameras.
Several companies and institutions - such as Amazon - use the technology to scan their employees.
The thermal camera will reveal whether an employee has an elevated body temperature or not. And in that case, the person may be infected with COVID-19 and may be sent home before more people in the workplace become infected.
However, it is important to be aware that the camera measures temperature, so if you have run to work or cycled at high speed, then you as a person can turn on a thermal camera because you are "warmer" than usual.
Should we help you design your thermal solution?
We have a great sense of thermal cameras, so you can safely let us help you select the right thermal cameras for your needs. If you need help setting up the camera, we can also help there.
