Perimeter fence

Since the 2000s, welded wire mesh and acoustic barriers have also become popular types of perimeter fence around the world.

Vertical bar, acoustic barriers and welded mesh are used in commercial projects and landmarks,[1] and transport hubs.

For example, a high wall with fence posts that protects a property discourages criminals from intruding and, when an incident occurs, increases the time it takes to carry it out.

The active security system consists of the following types of technology, which make up the fundamental architecture: Supporting these basic components, or forming a specialised part of them are the following accessories:

The sensors are the means by which all of the initial information on the threat status is collected and on which the operation of the active security subsystem is based.

The advantages of having a perimeter intrusion detection system are various, and of great importance, for example we obtain a remarkable capacity to analyse the information produced by each sensor, without the need to increase the resources at the centre.

Moreover, we obtain a faster analysis speed since it is made by each sensor, only for the part of the site that it is designed to protect.

The detectors can be classified in different ways, the most meaningful which are: The sensors are essentially made up of two parts: the first, called the transducer and the second, the analyser or processor.
