Perimeter Protection is a market segment representing about 6% of the Anti-Intrusion Security Industry which itself represents about 25% of the market for security.

According to standardized terminology, exterior protection via infrared barriers is termed :

Imperceptible and invisible in contrast to fence protection systems.

Peripheral when infrared barriers are installed at a distance around the building to protect.

Perimeter when infrared barriers are installed on the facade of the building to protect.

Two types of infrared barriers can be distinguished by their use: interior or exterior. We are going to focus especially on infrared barriers used outdoors. These differ from the interior type in the following aspects :

better weatherproofing

integrated thermostat-controlled heating

analysis of slow dimming (see fog curve p.8)

“ruggedised” and tropicalized electronics

performance of materials that make up the barriers in exterior conditions (cold-heat-humidity-UV exposure)
