Many owners and business people will often be confused from the terminology as well as the explanations given them by way of a security alarm representative. Sometimes what is recommended can be a good system, however it may also be beyond the budget of what many owners or business owners are able or need to pay.

The goal of this information is two-fold: first, to spell out the essential system and terms most generally available today, and second, to generate clear there are several numbers of protection available that can lead to different investments with higher or lower examples of overall protection for your house.



The conventional electronic home security system today is comprised of these elements:

User interface which processes the signals caused by the sensors, powers the sensors which require power, dials the monitoring central station to report alarms or events, powers the audible or visual devices, such as sirens and strobes, and supplies battery back-up in the event of AC power loss.

Sensors, for example door/window sensors which need no power, numerous motion detectors, including PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, such as water, CO2, or temperature, and naturally, fire and heat detectors.

The audible and quite often visual devices which might be put into the attic or under eaves in addition to within the dwelling.

The wire in order to connect the sensors and devices on the central cpanel, or perhaps many cases today, using wireless transmitter sensors with a receiver often included in the cpanel very few wires are expected (the AC transformer and speak to line still need to be “hard wired”).

The labor and programming to really make the pieces all come together.
The best degree of security–and obviously the one that will set you back the most–is full “perimeter” protection plus motion detector backup. Precisely what does this mean? It indicates every exterior door and window (no less than on the ground floor) features a magnetic switch, either recessed or surface mount in order that the alarm will go off prior to the intruder gets in the home. What’s more, it means placing some kind of glassbreak detectors either in each room that has glass or on each window itself to ensure, again, the alarm would go off before the intruder gets in.

If furthermore, motion detectors are strategically placed to ensure that from the unlikely event a thief would somehow defeat a protected perimeter entry point, and also gain entry inside the premises, he would now face devices that seem to be for motion by typically measuring the background temperature of your room from the temperature of an intruder (cause for “passive infrared technology” or PIR; which is essentially a kind of specialized camera looking for rapid adjustments to temperatures measured against an identification temperature).

These more complete type systems are also typically monitored by way of a central station to get a monthly monitoring fee. Lastly, for those worried about possible phone line cuts (e-mail, 99% of most alarms systems which are monitored by a central station make use of your phone line that’s often exposed on the side of the house or building) there are many of backup services available, from cellular to long term wireless to TCP/IP modules that go over the Internet with a special receiver at the central station.
