Fences Acquire Sensors And A Nuisance Problem
Fibre optic, accelerometer and taut wire systems turn a barrier into a detection line, and adoption grows at 10.5% as costs fall and regulators ask harder questions after every reported breach. The specification that decides success is nuisance alarm rate rather than detection probability, because a control room tolerating roughly one false alert per kilometre weekly will simply switch off any zone exceeding it. Vendors quote detection performance and buyers discover the other number afterwards. Buyers discover the other number within a month of the system going live at the site.
Market Impact: Excludes the 8% that matter
