Many homeowners and business people are often confused by the terminology and also the explanations given them by way of a burglar alarm representative. Sometimes what exactly is recommended can be a good system, but it can be past the budget of what homeowners or businesses have enough money or need to pay.
The purpose of this article is two-fold: first, to explain the basic system and terms most generally available today, and second, to create clear there are different levels of protection accessible that can result in different investments with higher or lower degrees of overall protection for your home or property.
The standard electronic alarm system today is made up of the following 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, like sirens and strobes, and gives battery back-up in the event of AC power loss.
Sensors, such as door/window sensors that need no power, a wide variety 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, not to mention, fire as well as heat detectors.
The audible and quite often visual devices which might be put into the attic or under eaves in addition to within the dwelling.
The wire in order to connect the sensors and devices to the central cp, or even in many cases today, the use of wireless transmitter sensors into a receiver often incorporated into the cpanel very few wires are expected (the AC transformer and speak to line still need to be "hard wired").
The labor and programming to help make the pieces all work together.
The very best level of security–and needless to say one that will set you back the most–is full "perimeter" protection plus motion detector backup. Exactly what does this implies? This means every exterior door and window (no less than on the ground floor) has a magnetic switch, either recessed or surface mount in order that the alarm goes off prior to the intruder gets inside your home. It also means placing some kind of glassbreak detectors either in each room which includes glass or on every window itself to ensure, again, the alarm would go off prior to the intruder gets in.
If additionally, motion detectors are strategically placed in order that within the unlikely event a burglar would somehow defeat a protected perimeter entry way, and actually gain entry within the premises, although now face devices that seem to be for motion by typically measuring the backdrop temperature of a room from the temperature of your intruder (basis for "passive infrared technology" or PIR; that is certainly essentially a sort of specialized camera trying to find rapid changes in temperatures measured against experience temperature).
These more complete type systems may also be typically monitored by a central station for a monthly monitoring fee. Lastly, for the people worried about possible line cuts (and yes, 99% of most alarms systems which can be monitored by the central station use your phone 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 that go over the net to some special receiver with the central station.
