EXACTLY HOW SECURITY SYSTEMS OPERATE

October 2018 ยท 3 minute read

Homeowners and businesses are often confused through the terminology and also the explanations given them by a alarm system representative. Sometimes what exactly is recommended may be a good system, nevertheless it are often after dark budget of the items many householders or companies have enough money or want to pay.

The intention of this article is two-fold: first, to spell out the essential system and terms most generally being used today, and 2nd, to produce clear there are different levels of protection available that can result in different investments with higher or lower levels of overall protection for the home or property.



The standard electronic security system today is comprised of the subsequent 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, for example sirens and strobes, and provides battery back-up in the event of AC power loss.

Sensors, for example door/window sensors which need no power, lots of motion detectors, for example PIRs’ or “dual” type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, like water, CO2, or temperature, and of course, fire and warmth detectors.

The audible and frequently visual devices which are put in the attic or under eaves as well as inside the dwelling.

The wire to get in touch the sensors and devices for the central cpanel, or in most all cases today, the usage of wireless transmitter sensors to some receiver often incorporated into the cpanel so few wires are required (the AC transformer and make contact with line still need to be “hard wired”).

The labor and programming to really make the pieces all come together.
The best level of security–and naturally the one which will set you back the most–is full “perimeter” protection plus motion detector backup. Precisely what does this implies? It means every exterior door and window (at least on a lawn floor) carries a magnetic switch, either recessed or surface mount so that the alarm go off prior to the intruder gets in the house. What’s more, it means placing some type of glassbreak detectors either in each room containing glass or on each window itself to ensure that, again, the alarm would set off prior to intruder gets in.

If furthermore, motion detectors are strategically placed so that from the unlikely event a burglar would somehow defeat a protected perimeter feeder point, and also gain entry inside premises, however now face devices that look for motion by typically measuring the history temperature of the room against the temperature associated with an intruder (cause for “passive infrared technology” or PIR; that is certainly essentially a kind of specialized camera looking for rapid modifications in temperatures measured against a background temperature).

These more complete type systems will also be typically monitored by the central station for a monthly monitoring fee. Lastly, for those concerned about possible telephone line cuts (and yes, 99% of most alarms systems which are monitored with a central station make use of your line that is often exposed to the side of the property or building) there are a variety of backup services available, from cellular to long range wireless to TCP/IP modules for the web with a special receiver on the central station.
