Homeowners and business people will often be confused through the terminology along with the explanations given them by way of a alarm system representative. Sometimes what is recommended can be a good system, but it can also be after dark budget of what homeowners or companies can afford or desire to pay.

The purpose of advantages and drawbacks two-fold: first, to clarify the essential system and terms most widely used today, and second, to create clear there are several levels of protection accessible that can translate into different investments with higher or lower levels of overall protection for that home or property.



The typical electronic home security system today is made up of these elements:

Cpanel 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 gives battery back-up in the case of AC power loss.

Sensors, including door/window sensors that want no power, lots of motion detectors, like PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, like water, CO2, or temperature, and of course, fire as well as heat detectors.

The audible and quite often visual devices which are placed in the attic or under eaves and also within the dwelling.

The wire to connect the sensors and devices towards the central cp, or perhaps many cases today, the usage of wireless transmitter sensors with a receiver often built-into the cp very few wires are required (the AC transformer and phone line still need to be “hard wired”).

The labor and programming to help make the pieces all work together.
The best degree of security–and needless to say one which will surely cost the most–is full “perimeter” protection plus motion detector backup. What does this suggest? It means every exterior door and window (no less than on the floor floor) features a magnetic switch, either recessed or surface mount in order that the alarm will go off before the intruder gets inside your home. In addition, it means placing some sort of glassbreak detectors in each room containing glass or on each window itself in order that, again, the alarm would go off prior to intruder gets in.

If furthermore, motion detectors are strategically placed to ensure that in the unlikely event an intruder would somehow defeat a protected perimeter feeder point, and also gain entry within the premises, he’d now face devices that look for motion by typically measuring the background temperature of a room contrary to the temperature of your intruder (cause for “passive infrared technology” or PIR; that is certainly essentially a sort of specialized camera looking for rapid alterations in temperatures measured against a background temperature).

These more complete type systems can also be typically monitored by the central station for any monthly monitoring fee. Lastly, for all those worried about possible line cuts (company, 99% of alarms systems which are monitored by the central station use your phone line which is often exposed along the side of the home or building) there are many of backup services available, from cellular to long term wireless to TCP/IP modules for the web to a special receiver at the central station.
