How the Alarm Monitoring System Works

August 25, 2009 · Posted in Home Security 

Home burglar alarms are in electronic form. One simple setup of an alarm system includes a sensor which is connected to one or more control units. When the sensor is triggered, the control unit seeks for a way to announce the home burglar alarm.

But basically, alarm systems can either be wireless or hardwired. The wired systems are usually used with sensors, smoke detectors for example, which always demand electricity for reliable operation. Wired types come with the advantage of detecting tampering. The only problem is that wired systems are very expensive to setup. On the other hand, wireless burglar alarm systems are easier to set-up. Instead of wires, they utilize transmitters. Wireless systems require constant supervision and maintenance to ensure efficient operation. If for example, the batteries or sensors have not been constantly checked.

alarm monitoring is employed in systems with a remote alarm output. In such systems, the control panels are connected to predetermined monitors, and they are configured in various methods. One includes a direct connection of the system to a responder, or a central station, such as a police quarters. However, this kind of configuration is becoming less popular because it is expensive. Direct monitoring connections can usually be found only in Local Government institutions, State, or school campuses where there is a dedicated security.

More conventional alarm systems make use of Public Switched Telephone Network, or PSTN. This configuration features a digital phone dialer unit which will dial the central station, in which it will announce the alarm. The monitoring system can identify the physical location of the sensor that has been triggered with the use of certain programmed encoders. Most alarm control panels are designed with backup dialer ability that can be used when the primary PSTN route is not functioning well. The secondary dialer can be connected to a separate phone line (or an encoded radio, mobile phone, or internet interface gadgets) to entirely evade the PSTN. This is because if the primary lines have been tampered with, alarms can still be raised with the use of redundant dialers and early warnings of pending problems can be advised.

If the building is located in a remote area, PSTN service may not be feasible and channeling a direct line may be too expensive, there is still a way so your security can be monitored. And that is by using wireless phones or radio networks as the principal communication line. The use of the Internet as a main communication method is still a very big issue within the alarm monitoring business. This is because an alarm signaling method needs to observe urgency and immediacy, and the authorities are doubtful of the quality of service of public internet.

Once monitored, the alarms and speaker phones allow the central station to communicate with the owner. For monitored burglaries, the speaker phones let the central stations to convince the prowler to back off and give up as police units have been sent off.

If we consider some factors, such as the location of the zone triggered and the time of the day, the alarm monitoring center may perform various actions automatically. Some instructions they may initiate include calling the police stations, fire department or ambulance. They may also choose to check if the alarm is true. Some systems come also with video surveillance to capture the actual acts of intrusion or other emergency cases on tapes.
