Description
Detection devices are components used to detect intrusion and may also at times be referred to as sensors. They must be capable of reliably detecting intruders and exhibit a high resistance to false activations. Detection devices utilise a wide range of technologies.
They may be passive devices such as a basic switch or contact. Alternatively, they may be powered active devices that have onboard signal processing to determine whether an intrusion is taking place.
