Thermal imaging cameras are not designed to allow the identification of individuals from their facial features or clothing – although they can see a surprising amount of detail. What they are excellent at doing is allowing recognition of potential threats by revealing details which are hidden to the human eye and to conventional cameras.
Their effectiveness starts a long way out, with the detection of potential targets delivered in all lighting conditions, and regardless of undergrowth and similar cover; a typical application is in border security, where they easily achieve a 2km surveillance range, allowing 4km spacing between cameras.
Closer in and the thermal camera will clearly show what the target object is – a person, a group of people, a vehicle etc. Closer still and clear details are revealed, showing what the person is doing, carrying and, to an extent, wearing.
For commercial security applications this provides all the necessary information for the appropriate response to be triggered – whether that be continued remote monitoring, remote warnings, or direct intervention.
The fact that thermal cameras cannot be used to positively identify individuals should be taken into account when designing the security system – and in some cases, where privacy is important, this may even be an advantage.
Exactly what your thermal camera will see, at what distance, depends on local conditions; the technology is well tested in the field and detailed technical advice is available from experienced manufacturers such as FLIR which will can be used to plan the most effective, layered security protection for any application.
