Burglar alarm monitoring means that a professional alarm monitoring centre would be notified should your alarm ever be triggered. There are 3 main methods of monitoring, depending on what level of security you require: digital monitoring uses a standard telephone line; DualCom GPRS operates via a phoneline and GPRS; and BT Redcare GSM operates via a phoneline and GSM.
The type of monitoring solution you choose should be determined by the level of back up you require. Digital monitoring is fine for most but would fail should the phoneline fault or be cut. DualCom offers a dual signalling system so that it will still notify the response centre should the line be tampered with. BT RedCare is the most secure monitoring system as it continuously monitors the alarm and would be able to detect any issues with the line, even if the alarm itself was not triggered.
