Many homeowners and businesses are often confused by the terminology and the explanations given them by a burglar alarm representative. Sometimes precisely what is recommended may be a good system, nonetheless it can also be past the budget of the many homeowners or companies can afford or desire to pay.

The intention of this post is two-fold: first, to explain the fundamental system and terms most widely being used today, and 2nd, to create clear there are various levels of protection available that can translate into different investments with higher or lower numbers of overall protection for your home or property.



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

User interface which processes the signals 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 case of AC power loss.

Sensors, such as door/window sensors which need no power, lots of motion detectors, such as PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, such as water, CO2, or temperature, as well as, fire and also heat detectors.

The audible and quite often visual devices which might be used in the attic or under eaves and also inside dwelling.

The wire to get in touch the sensors and devices towards the central cp, or perhaps in most all cases today, the application of wireless transmitter sensors with a receiver often included in the cp so few wires are essential (the AC transformer and call line still need to be “hard wired”).

The labor and programming to really make the pieces all communicate.
The best degree of security–and naturally one which will definitely cost the most–is full “perimeter” protection plus motion detector backup. What does this imply? It implies every exterior window and door (at the very least on the ground floor) has a magnetic switch, either recessed or surface mount in order that the alarm go off ahead of the intruder gets inside your home. In addition, it means placing some type of glassbreak detectors in both each room which includes glass or on every window itself in order that, again, the alarm would go off prior to the intruder gets in.

If in addition, motion detectors are strategically placed in order that within the unlikely event a burglar would somehow defeat a protected perimeter access point, and also gain entry within the premises, however now face devices that look for motion by typically measuring the setting temperature of the room up against the temperature of an intruder (cause for “passive infrared technology” or PIR; that’s essentially sort of specialized camera searching for rapid adjustments to temperatures measured against a background temperature).

These more complete type systems will also be typically monitored by way of a central station for a monthly monitoring fee. Lastly, for anyone concerned about possible telephone line cuts (e-mail, 99% of all alarms systems which are monitored with a central station use your telephone line that’s often exposed along the side of the home or building) there are many of backup services available, from cellular to long range wireless to TCP/IP modules for the world wide web to a special receiver in the central station.
