Cross Zoning
Cross zoning is a strategy that does not require a new keypad. Using multiple sensors to monitor activity in one area, software analyzes input from all the sources. For example, if a motion detector trips in one area, the signal is recorded and the central-station monitor notifies the customer. A second alarm signal – received in an adjacent zone within a short time – is the confirmation the central-station monitor needs to request a dispatch immediately. This builds in increased protection and a fail safe should a door blow open or a bird rattle an exterior window.
