Get the best security alarms and alarm system installation from expert professionals
Installing a Smartway security alarm system may effectively decrease the chances of a burglary at your home or business. Even if the alarm system does not keep a burglar from breaking in, it should reduce the time the intruder spends in your premises; thus making it difficult for them to steal a vast amount of goods. It turns an opportunist intruder into a smash and grab scenario as they are unsure of how long they may have before someone responds to it!
Most security systems rely on a combination of detectors placed at doors (and sometimes on the windows) and Passive Infra-Red (PIR) motion sensors. Indoor motion sensors are normally used as the primary means of detection but they do not detect someone until they are already in the house, there would only likely be a couple of seconds difference between using this method and that of using a reed switch on doors and windows – plus it is cheaper to install.
For larger commercial buildings it is advisable that potential entry points such as Roller Doors have reed switch contacts that detect when they are opened. Digital glass break sensors are also available and are greatly recommended to commercial customers.
