What is called "building" represents all rigid construction. For a site, the first is the perimeter, usually made with a wall, to separate the public area and the site's premises.

​

This perimeter has some access that can be managed by technology or manually. In a site, we often separate the areas to split activity according to various needs such as confidentiality, risk, disturbance, etc.

 

We usually base the security according to the "building" to separate the crowds, such as the public, technicians, customers, and providers. Understanding the company's functioning is essential to avoid building modification, which can impact the business running. Nevertheless, it is also possible to reinforce it with technology or even hard additional items such as bulletproof glass, bollards or roadblocks.
