PRECISELY HOW SECURITY SYSTEMS OPERATE

Many homeowners and businesses in many cases are confused by the terminology and the explanations given them by the burglar alarm representative. Sometimes what is recommended might be a good system, nonetheless it are often beyond the budget products many owners or business people are able to afford or desire to pay.

The objective of this information is two-fold: first, to clarify the basic system and terms most generally used today, and second, to create clear there are numerous degrees of protection accessible that can produce different investments with higher or lower numbers of overall protection for your home or property.



The standard electronic alarm system today is composed of these elements:

User interface 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, including sirens and strobes, and supplies battery back-up in the eventuality of AC power loss.

Sensors, for example door/window sensors that need no power, a multitude of motion detectors, like 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 warmth detectors.

The audible and frequently visual devices that are used in the attic or under eaves and also in the dwelling.

The wire for connecting the sensors and devices on the central user interface, or perhaps most cases today, using wireless transmitter sensors into a receiver often integrated into the cp very few wires are essential (the AC transformer and call line still need be “hard wired”).

The labor and programming to help make the pieces all come together.
The best level of security–and obviously one which will surely cost the most–is full “perimeter” protection plus motion detector backup. What does this suggest? It implies every exterior door and window (no less than on the ground floor) has a magnetic switch, either recessed or surface mount so that the alarm goes off prior to the intruder gets in the house. It also means placing some form of glassbreak detectors in each room which includes glass or on every window itself in order that, again, the alarm would disappear ahead of the intruder gets in.

If furthermore, motion detectors are strategically placed so that inside the unlikely event an intruder would somehow defeat a protected perimeter entry way, and actually gain entry inside the premises, however now face devices that look for motion by typically measuring the backdrop temperature of an room from the temperature of the intruder (cause for “passive infrared technology” or PIR; which is essentially some type of specialized camera trying to find rapid modifications in temperatures measured against experience temperature).

These more complete type systems will also be typically monitored by a central station for a monthly monitoring fee. Lastly, for the people worried about possible phone line cuts (company, 99% coming from all alarms systems which might be monitored by a central station takes place line that is certainly often exposed on the side of the home or building) there are a number of backup services available, from cellular to long term wireless to TCP/IP modules for the world wide web with a special receiver at the central station.
