Perimetric protection should be linked to the camera system in order to enable an immediate evaluation of an alert. The priority of perimetric protection is not the absence of false alarms; generally, higher levels of security involves more sensitive systems, which leads in practice to an increased frequency of false alarms in need of examination.
Perimetric protection systems require a particularly thorough design. A combination of technologies is usually used, so that an optimal system that corresponds to the required security level and falls within a suitable price range can be designed.
There is a big difference between the perimetric protection of a house and a high-security site. The required security level significantly influences the total cost of the solution.
When planning systems for sites with the highest security level, additional necessary operational and organisational measures have to be allowed for, by creating special zones, etc. Plans for residential sites, however, also require consideration of the environmental parameters, otherwise the system will be unreliable or completely dysfunctional.
Technologies can be installed so that they are apparent, contributing a deterring function, or unapparent and built into the architecture or located underground, for such sites where aesthetics is key (mainly historic sites) or where the owner needs a specific level of security without attracting attention.
