Many homeowners and business people in many cases are confused from the terminology and the explanations given them by way of a alarm system representative. Sometimes what is recommended can be a good system, nonetheless it can be after dark budget of what homeowners or business people are able to afford or want to pay.

The intention of this post is two-fold: first, to clarify the essential system and terms most widely used today, and 2nd, to generate clear there are numerous numbers of protection available that can result in different investments with higher or lower degrees of overall protection for your home or property.



The normal electronic security system today is made up of the next elements:

Cp 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, including sirens and strobes, and offers battery back-up in case of AC power loss.

Sensors, such as door/window sensors which need no power, lots of motion detectors, for example PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, such as water, CO2, or temperature, not to mention, fire and heat detectors.

The audible and often visual devices that are put into the attic or under eaves along with in the dwelling.

The wire to connect the sensors and devices to the central cpanel, or perhaps most all cases today, the use of wireless transmitter sensors with a receiver often included in the user interface very few wires are required (the AC transformer and call line still need to be “hard wired”).

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

If in addition, motion detectors are strategically placed to ensure inside the unlikely event a thief would somehow defeat a protected perimeter entry point, and in actual fact gain entry inside premises, however now face devices that seem to be for motion by typically measuring the background temperature of the room up against the temperature of your intruder (cause for “passive infrared technology” or PIR; that’s essentially some type of specialized camera searching for rapid modifications in temperatures measured against a background temperature).

These more complete type systems will also be typically monitored by a central station for a monthly monitoring fee. Lastly, for those concerned about possible line cuts (e-mail, 99% of most alarms systems which might be monitored with a central station use your telephone line that is often exposed along the side of your home or building) there are a selection of backup services available, from cellular to long range wireless to TCP/IP modules that go over the Internet to some special receiver at the central station.
