A type of alarm communication path that uses a digital cellular network to send alarm signals from the control panel to a monitoring center's cellular receivers. This type of alarm monitoring requires a digital cellular communicator that is hardwired into the security system and a cellular monitoring contract. Cellular monitoring does not require phone lines, and there is no chance of the purposeful or accidental cutting of your alarm communication line. Therefore, cellular monitoring is one of the most reliable ways to monitor a security system. Cellular devices can also be mobile, providing an opportunity for the central station to monitor the physical location of the devices as necessary.
