Many householders and business people will often be confused from the terminology and also the explanations given them by way of a alarm system representative. Sometimes what is recommended could be a good system, however it may also be past the budget of the items many householders or businesses have enough money or wish to pay.

The purpose of advantages and drawbacks two-fold: first, to clarify the fundamental system and terms most generally used today, and 2nd, to generate clear there are various amounts of protection available that can produce different investments with higher or lower degrees of overall protection for the house.



The conventional electronic home security system today is made up of the following 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, for example sirens and strobes, and provides battery back-up in the event of AC power loss.

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

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

The wire for connecting the sensors and devices for the central cpanel, or perhaps many cases today, the usage of wireless transmitter sensors into a receiver often integrated into the cpanel very few wires are expected (the AC transformer and make contact with line still need be “hard wired”).

The labor and programming to help make the pieces all interact.
The highest degree of security–and of course the one that will definitely cost the most–is full “perimeter” protection plus motion detector backup. Exactly what does this mean? It indicates every exterior window and door (at the very least in the grass floor) has a magnetic switch, either recessed or surface mount in order that the alarm will go off ahead of the intruder gets in the house. What’s more, it means placing some type of glassbreak detectors in both each room that has glass or on each window itself to ensure that, again, the alarm would disappear before the intruder gets in.

If in addition, motion detectors are strategically placed so that in the unlikely event a burglar would somehow defeat a protected perimeter access point, and in actual fact gain entry inside premises, he would now face devices that are for motion by typically measuring the setting temperature of an room up against the temperature of the intruder (grounds for “passive infrared technology” or PIR; that’s essentially some type of specialized camera looking for rapid modifications in temperatures measured against a background temperature).

These more complete type systems can also be typically monitored by a central station for any monthly monitoring fee. Lastly, for anyone concerned with possible line cuts (and yes, 99% of all alarms systems which can be monitored by a central station make use of telephone line that is often exposed along the side of the property or building) there are a selection of backup services available, from cellular to long term wireless to TCP/IP modules that go over the world wide web into a special receiver with the central station.
