Redundant Monitoring

Redudant monitoring is the term used when an alarm signal is monitored using more than one process. Redundant monitoring can be satisfied by a variety of techniques: 1. multiple servers (within the same company) handle and verify the signal; 2. the signal is sent to multiple central stations; or 3. more than one type of signal is used to transmit the alarm. The purpose of redundant monitoring is to guard against possible system failures like power outages or busy networks and to ensure that, during an alarm event, the signal will be received in a timely manner by a security professional.

Some monitoring providers employ a two-level (“double”) redundant monitoring process, while others use triple or even quadruple layers.

It’s quite common to conduct redundant monitoring by using a second signal type as a back-up to your primary method of alarm signal transmission.  The redundant or secondary signal could be connected to a second phone line, a cell phone, radio or internet device. Many systems that use VoIP, Broadband or cellular technologies as the primary alarm signal will use a land-line as back-up.

Some web-based DIY security systems operate using  redundant monitoring, so that when an alarm is tripped, the signal will be sent to a central monitoring station as well as to you.  You are able to customize features like who will be responsible for contacting the authorities to dispatch help to the residence and how many contacts will be attempted before help is dispatched, thereby protecting against false alarms.
