When designing a protection system we approach the task from four principles – Detect, Determine, Delay and Defend. These principles allow us to protect an area through the application of appropriate technology.
Detect – is the process of identifying specific activity that is to be alerted to the security team. Detection should be made at the earliest opportunity. Detection technologies include radar, fibre optic sensors and infrared beams.
Determine – is the ability to verify the detected event so that false or nuisance activations are eliminated and valuable intelligence is gathered relating to real events. Determination technologies include long range CCTV and thermal imaging.
Delay – is important to allow a security response to be initiated. This may be a physical barrier or an open area that will take time to cross. Delay technologies include fencing, gates and barriers.
Defend – is the deployment of technology to deter or repel a security breach. Defence technology includes power fence and electronic jammers.
