Many householders and business people will often be confused by the terminology as well as the explanations given them by a burglar alarm representative. Sometimes precisely what is recommended could be a good system, however it can be beyond the budget products many owners or business people have enough money or wish to pay.

The purpose of this post is two-fold: first, to spell out the basic system and terms most widely being used today, and secondly, to generate clear there are different amounts of protection available that can translate into different investments with higher or lower levels of overall protection for the home or property.



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

Cpanel 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 eventuality of AC power loss.

Sensors, such as door/window sensors that need no power, a multitude 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, and of course, fire and heat detectors.

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

The wire to connect the sensors and devices on the central user interface, or in most cases today, the use of wireless transmitter sensors to a receiver often integrated into the cpanel very few wires are needed (the AC transformer and make contact with line still have to be “hard wired”).

The labor and programming to make the pieces all communicate.
The greatest degree of security–and of course the one which will cost the most–is full “perimeter” protection plus motion detector backup. Simply what does this implies? It implies every exterior window and door (at least on the ground floor) features a magnetic switch, either recessed or surface mount so that the alarm will go off prior to intruder gets in the home. In addition, it means placing some form of glassbreak detectors in each room that has glass or on every window itself to ensure, again, the alarm would set off prior to intruder gets in.

If moreover, motion detectors are strategically placed in order that inside the unlikely event an intruder would somehow defeat a protected perimeter feeder point, and in actual fact gain entry inside premises, although now face devices that look for motion by typically measuring the setting temperature of a room from the temperature associated with an intruder (cause of “passive infrared technology” or PIR; that is certainly essentially some type of specialized camera seeking rapid changes in temperatures measured against experience temperature).

These more complete type systems can also be typically monitored by way of a central station for the monthly monitoring fee. Lastly, for anyone concerned with possible phone line cuts (and yes, 99% of all alarms systems which can be monitored with a central station takes place telephone line which is often exposed to the side of the property or building) there are a number of backup services available, from cellular to long range wireless to TCP/IP modules for the world wide web to some special receiver with the central station.
