Perimeter intrusion detection systems (PIDS) have to deal with a wide range of environmental conditions, while detecting stealthy human motion and ignoring nuisance events.Imagine detecting a person moving in a stealthy fashion, perhaps crawling, through an open perimeter in the midst of a heavy rain with poor visibility over uneven terrain, while ensuring that alarms are not triggered by rain or wind. Today, good sensors perform these tasks quite well.
The core challenge is specifying the correct sensor for a specific environment. Asking a supplier for advice is one option, but if the the supplier is tied into a particular product they will sometimes try to convince you that they have exactly the right product for you. In the experience of ARC consultants, many hundreds of PID systems worldwide are working less than satisfactorily because the wrong system has been specified for a given location.
PIDS are covered in detail in the following 2008 ARC Training programmes:
- Specifying Security Systems, 21-25 July
- Security Management Stage 1, 31 March – 11 April , 4-15 August 2, 17-28 November
- ASIS PSP Review Course, 27-31 October
- ASIS CPP Review Course, 28 April – 2 May 2008, 27-31 October
