A security alarm system is designed to detect unauthorized entry into a building or area. These systems are used in residential, commercial, industrial, and military properties to protect against burglary, property damage, and personal threats. While some alarm systems focus solely on burglary protection, others combine both fire and intrusion protection. Many intrusion alarm systems integrate with closed-circuit television (CCTV) to automatically record intruder activities and interface with access control systems for managing electrically locked doors. Systems vary from simple, self-contained units to complex, multi-area configurations.
In rural areas (e.g., where nobody will hear the fire bell or burglar siren) lights or sounds may not make much difference anyway, as the nearest responders could take so long to get there that nothing can be done to avoid losses.
Remote alarm systems are used to connect the control unit to a predetermined monitor of some sort, and they come in many different configurations. High-end systems connect to a central station or responder (e.g. Police/ Fire/ Medical) via a direct phone wire, a cellular network, a radio network (i.e. GPRS/GSM) or an IP path.
In the case of a dual signalling system two of these options are utilized simultaneously. The alarm monitoring includes not only the sensors, but also the communication transmitter itself. While direct phone circuits are still available in some areas from phone companies, because of their high cost and the advent of dual signalling with its comparatively lower cost they are becoming uncommon.
A dual signalling system would raise the alarm wirelessly via a radio path (GPRS/GSM) or cellular path using the phone line or broadband line as a back-up overcoming any compromise to the phone line. Encoders can be programmed to indicate which specific sensor was triggered, and monitors can show the physical location (or "zone") of the sensor on a list or even a map of the protected premises, which can make the resulting response more effective. For example, a heat sensor alarm, coupled with a flame detector in the same area is a more reliable indication of an actual fire than just one or the other sensor indication by itself.
Many alarm panels are equipped with a backup communication path for use when the primary PSTN circuit is not functioning. The redundant dialer may be connected to a second communication path, or a specialized encoded cellular phone, radio, or internet interface device to bypass the PSTN entirely, to thwart intentional tampering with the phone line(s).
Just the fact that someone tampered with the line could trigger a supervisory alarm via the radio network, giving early warning of an imminent problem (e.g., arson). In some cases a remote building may not have PSTN phone service, and the cost of trenching and running a direct line may be prohibitive. It is possible to use a wireless cellular or radio device as the primary communication method.
