There are a number of detection technologies in today’s arsenal today for detecting persons or vehicles penetrating a facilities perimeter boundary. However, no single optimum solution for all security applications exists, and each technology type has its place dependent on the site and organisation requiring protection.
Five major factors influence the choice of technology when considering implementing a perimeter detection system; risk, location, terrain, structure and standards.
Foremost, the technology must be commensurate with the risk requiring protection and the sophistication of any potential assailant(s) and their likely method of penetration. The chosen technology must be suitable for the geographic location; harsh environment, climate; rainy, dry etcetera and the terrain and topography; hilly, marsh, flat.
It also needs to be appropriate for the structure in will be installed on or within. Finally, it must meet with any national or local standards – eg BS EN5013 – or planning permission.
Dependent on the organisation or risk it is also advisable to consider using complementary technologies to either increase detection rate (security) or decrease nuisance and false alarm rates by requiring both technologies to go into alarm before triggering an alert.
