Perimeter protection means that a terrain is sensitized to unauthorized penetration within its entire circumference. JERRA LASER SCANNERS PERIMETRY protect reliably. Wherever access is desired, our finger-readers are located, where the persons with a right to access can identify themselves and then gain access to buildings and installations. At the same time, all the other buildings and areas remain protected. This is where our biometric know-how really scores – for example, when it is necessary to secure cargo, parking lots, solar parks, construction sites, sensitive infrastructures such as transformer substations, drinking water plants or refineries, factory premises, and also closed institutions on a large scale. And it is totally modern and discreet, functioning without walls or barbed wire.
