Home security alarm systems can be monitored or non-monitored. A monitored system is linked to a central law enforcement office, whereas a non-monitored system is only linked to the home. Monitored systems are more expensive because they provide an ongoing service from security companies, who normally charge a monthly fee to respond to any security threats to your home. For homeowners who want immediate emergency response if their alarm is triggered, monitored systems are the best option.
Non-monitored security systems have the advantage of being cheaper as they do not come with a security service. With non-monitored systems, there is no guarantee the local police will respond to an alarm in a timely fashion.
Wired alarm systems make use of electrical wires to trigger the central alarm system. Wireless security systems, in contrast, make use of radio transmitters to trigger the alarm’s central system and are known for being less reliable than wired systems but are much easier to install. However, both systems are usually equipped with backup battery systems that take over if electrical or radio transmitter systems fail.
Most alarm systems, whether monitored or unmonitored, wired or wireless, come with the following system implements. A security keypad is a standard tool for arming or disarming the alarm system. Passive infrared detectors, otherwise known as motion detectors, come with all alarm systems and are the foremost detector of unusual activity in the home. Passive infrared detectors are triggered when heat and motion passes inform of the security beam.
