Many homeowners and businesses in many cases are confused by the terminology along with the explanations given them by the alarm system representative. Sometimes precisely what is recommended could be a good system, nonetheless it are often beyond the budget of the items many homeowners or businesses are able or desire to pay.

The intention of this information is two-fold: first, to clarify the essential system and terms most generally in use today, and secondly, to make clear there are different levels of protection accessible that can produce different investments with higher or lower degrees of overall protection for your home or property.



The standard electronic security system today is comprised of these elements:

Control panel which processes the signals coming 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, like sirens and strobes, and offers battery back-up in the event of AC power loss.

Sensors, for example door/window sensors that want no power, lots of motion detectors, like PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, like water, CO2, or temperature, and naturally, fire and warmth detectors.

The audible and often visual devices which are used in the attic or under eaves as well as inside dwelling.

The wire to get in touch the sensors and devices for the central control panel, or perhaps most cases today, the usage of wireless transmitter sensors to a receiver often integrated into the user interface so few wires are essential (the AC transformer and make contact with line still need to be “hard wired”).

The labor and programming to really make the pieces all work together.
The greatest level of security–and needless to say one which will cost the most–is full “perimeter” protection plus motion detector backup. Precisely what does this mean? It implies every exterior door and window (no less than on a lawn floor) features a magnetic switch, either recessed or surface mount so the alarm should go off prior to intruder gets in the house. It also means placing some form of glassbreak detectors in each room which includes glass or on every window itself to ensure, again, the alarm would disappear prior to intruder gets in.

If moreover, motion detectors are strategically placed to ensure within the unlikely event a thief would somehow defeat a protected perimeter entry point, and also gain entry inside premises, he’d now face devices that are for motion by typically measuring the history temperature of an room against the temperature of an intruder (cause for “passive infrared technology” or PIR; that is essentially some type of specialized camera trying to find rapid modifications in temperatures measured against a credentials temperature).

These more complete type systems may also be typically monitored by the central station to get a monthly monitoring fee. Lastly, for the people worried about possible phone line cuts (e-mail, 99% of all alarms systems that are monitored by a central station make use of your phone line that is certainly often exposed on the side of your home or building) there are many of backup services available, from cellular to long term wireless to TCP/IP modules for the Internet to a special receiver at the central station.
