Unlike our eyes, thermal image cameras don’t use visible-light to create an image, they use heat. This gives FLIR thermal cameras an advantage over low-light cameras and standard CCTV cameras, particularly when lighting cannot be installed, or when installing lighting is too expensive.


FLIR thermal camera biggest advantage is the range they offer. Added range give security professionals more time to react to security threats. Because thermal cameras detect the tiny differences in heat, and because this heat is much easier to detect long ranges compared to visible light thermal cameras have a clear advantage.


Not only can FLIR thermal security cameras detect heat over long distances, they are not susceptible to camouflage because it’s impossible for an intruder to hide their heat.


One criticism of Thermal technology is that with an IR camera you can identify an intruder better than with a FLIR thermal camera – as thermal cameras don’t show the same detailed image that traditional cameras do. However, thermal cameras can identify that there is a threat much better than IR cameras. They can be used in conjunction with traditional cameras or as an alert to let you know to investigate further. FLIR have stated: “identify your intruder when he is in handcuffs.”


At night there is no sunlight to bounce off objects, so all traditional CCTV cameras can use is starlight, moonlight and artificial lighting. If there isn’t enough light, the cameras won’t pick up anything. Infrared (IR) cameras get around this by using their own light source to illuminate an area to record, but their range is limited. The light they generate has to go to the target area then be bounced back to the camera lens, and a lot of this energy is lost.



Thermal cameras also have the advantage of being to see through smoke, rain and fog. As long as thermal energy can still reach the lens, the camera can still create a useful image. A thermal imaging camera produces an image based on tiny differences in thermal radiation, or heat, that an object produces. These cameras are an invaluable tool for all security teams.
