Many owners and businesses tend to be confused with the terminology along with the explanations given them by a alarm system representative. Sometimes what exactly is recommended may be a good system, but it can also be after dark budget of the items homeowners or business people have enough money or want to pay.

The intention of this post is two-fold: first, to describe the fundamental system and terms most widely in use today, and secondly, to produce clear there are numerous numbers of protection accessible that can produce different investments with higher or lower numbers of overall protection for your house.



The standard electronic home security system today is composed of these elements:

Control panel which processes the signals from the sensors, powers the sensors which require power, dials the monitoring central station to report alarms or events, powers the audible or visual devices, including sirens and strobes, and gives battery back-up in the event of AC power loss.

Sensors, such as door/window sensors that need no power, a multitude of motion detectors, including PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, like water, CO2, or temperature, as well as, fire and also heat detectors.

The audible and quite often visual devices which might be used in the attic or under eaves along with in the dwelling.

The wire to get in touch the sensors and devices to the central cpanel, or perhaps most cases today, the use of wireless transmitter sensors with a receiver often built-into the control panel very few wires are required (the AC transformer and call line still need to be “hard wired”).

The labor and programming to really make the pieces all communicate.
The best level of security–and naturally one that will cost the most–is full “perimeter” protection plus motion detector backup. Exactly what does this imply? It implies every exterior door and window (at least on a lawn floor) has a magnetic switch, either recessed or surface mount so your alarm should go off prior to the intruder gets in the house. It also means placing some sort of glassbreak detectors in both each room which includes glass or on each window itself to ensure, again, the alarm would go off prior to intruder gets in.

If in addition, motion detectors are strategically placed so that inside the unlikely event a burglar would somehow defeat a protected perimeter entry way, and gain entry within the premises, however now face devices that are for motion by typically measuring the backdrop temperature of the room against the temperature associated with an intruder (cause for “passive infrared technology” or PIR; that is essentially some type of specialized camera trying to find rapid alterations in temperatures measured against an identification temperature).

These more complete type systems may also be typically monitored by way of a central station for the monthly monitoring fee. Lastly, for those concerned with possible telephone line cuts (and yes, 99% of alarms systems which might be monitored by way of a central station make use of your telephone line which is often exposed to the side of the home or building) there are many of backup services available, from cellular to long term wireless to TCP/IP modules that go over the web to some special receiver on the central station.
