Thermal imaging

Learn about how you can detect more, and spend less.

When you need reliable round-the-clock detection, Axis thermal cameras are an excellent – and cost-effective – solution.

There’s no hiding from them. Because they capture images based solely on the heat radiating from people and objects, they’re unaffected by darkness or poor visibility. So they’re as accurate in pitch black, fog, and camouflage as they are on a bright sunny day.

Just like our visual cameras, Axis thermal cameras support intelligent analytics. In combination with the cameras, these analytics analyze detected incidents, automatically dismiss non-threatening ones, and immediately notify security of critical situations.

Thermal cameras don’t deliver images that allow reliable identification. So if privacy regulations are a concern, you’ll remain safely in compliance. And we also offer explosion-protected cameras based on thermal technology that feature protective housing. They’re certified worldwide for use in hazardous areas.

It’s clear: Axis thermal cameras give you the “sight” – and the insight – you need to protect property, perimeters, and people.

The role of intelligent thermal cameras

Thermal cameras with integrated analytics applications have a specific – and important – role to play in a complete surveillance system.

Detect: Thermal cameras detect suspicious behavior and objects even in dark scenes and other difficult light conditions.

Verify: As soon as a thermal camera has detected something suspect, an operator can verify that the activity is really a threat.

Act: Once activity has been verified as suspicious, the thermal camera, acts in response. For example it can:

Automatically notify security
Trigger visual cameras to identify people or vehicles
Trigger lights or a speaker to deter the crime

A peek inside a thermal camera

Thermal cameras work because all objects – organic or inorganic – emit a certain amount of infrared radiation as a function of their temperature. Like all cameras, thermal cameras collect electromagnetic radiation, which is formed into an image. Conventional cameras work in the range of visible light, in other words, with radiation with short wavelengths. Thermal cameras, on the other hand, detect radiation with mid-length or long wavelengths, which is called infrared radiation.

The main difference between infrared radiation and radiation with a shorter wavelength is that infrared radiation is emitted rather than reflected. Since the object themselves emits the light (heat) thermal cameras detect, thermal cameras are not dependent on visible light and can detect in all light conditions, day or night. You can learn more about thermal imaging in our white papers, which you’ll find below.
