Many householders and business people tend to be confused with the terminology and the explanations given them with a alarm system representative. Sometimes what is recommended can be a good system, however it may also be past the budget of the items many homeowners or businesses can afford or want to pay.
The purpose of this article is two-fold: first, to spell out the fundamental system and terms most widely used today, and secondly, to produce clear there are different levels of protection available that can lead to different investments with higher or lower degrees of overall protection for your house.
The normal electronic security system today is comprised of the next elements:
User interface which processes the signals received 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, such as sirens and strobes, and gives battery back-up in the case of AC power loss.
Sensors, like door/window sensors that need no power, numerous motion detectors, like PIRs’ or "dual" type detectors, glassbreak sensors, hold-up or panic switches, environmental sensors, for example water, CO2, or temperature, as well as, fire and heat detectors.
The audible and sometimes visual devices which are used in the attic or under eaves and also in the dwelling.
The wire in order to connect the sensors and devices towards the central cpanel, or perhaps many cases today, the use of wireless transmitter sensors with a receiver often included in the control panel so few wires are required (the AC transformer and phone line still need to be "hard wired").
The labor and programming to make the pieces all communicate.
The highest level of security–and needless to say the one that will surely cost the most–is full "perimeter" protection plus motion detector backup. Exactly what does this suggest? It means every exterior door and window (at the very least on a lawn floor) has a magnetic switch, either recessed or surface mount so that the alarm goes off before the intruder gets in the house. What’s more, it means placing some sort of glassbreak detectors either in each room containing glass or on each window itself to ensure that, again, the alarm would go off before the intruder gets in.
If furthermore, motion detectors are strategically placed in order that within the unlikely event an intruder would somehow defeat a protected perimeter entry way, and actually gain entry within the premises, although now face devices that are for motion by typically measuring the history temperature of an room up against the temperature of the intruder (grounds for "passive infrared technology" or PIR; that is essentially a sort of specialized camera looking for rapid changes in temperatures measured against a credentials temperature).
These more complete type systems will also be typically monitored by the central station for the monthly monitoring fee. Lastly, for those concerned with possible phone line cuts (and yes, 99% of all alarms systems which can be monitored with a central station use your line which is often exposed on the side of your home or building) there are many of backup services available, from cellular to long range wireless to TCP/IP modules for the net to a special receiver on the central station.
