Many owners and companies in many cases are confused with the terminology and the explanations given them by the burglar alarm representative. Sometimes precisely what is recommended might be a good system, nonetheless it may also be at night budget of the items many homeowners or businesses are able to afford or need to pay.
The goal of this information is two-fold: first, to explain the fundamental system and terms most widely in use today, and 2nd, to produce clear there are several degrees of protection available that can lead to different investments with higher or lower numbers of overall protection to the house.
The normal electronic home security system today includes 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, like door/window sensors that want no power, a wide variety 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 also heat detectors.
The audible and quite often visual devices which might be placed in the attic or under eaves along with in the dwelling.
The wire to connect the sensors and devices towards the central cp, or perhaps many cases today, using wireless transmitter sensors to a receiver often included in the user interface very few wires are needed (the AC transformer and make contact with line still have to be "hard wired").
The labor and programming to make the pieces all interact.
The very best a higher level security--and obviously the one that will cost the most--is full "perimeter" protection plus motion detector backup. What does this imply? This means every exterior window and door (at the very least on the floor floor) has a magnetic switch, either recessed or surface mount so that the alarm go off ahead of the intruder gets inside your home. It also means placing some type of glassbreak detectors in each room that has glass or on each window itself to ensure that, again, the alarm would stop before the intruder gets in.
If in addition, motion detectors are strategically placed so that in the unlikely event a burglar would somehow defeat a protected perimeter access point, and gain entry within the premises, although now face devices that seem to be for motion by typically measuring the background temperature of your room contrary to the temperature associated with an intruder (cause for "passive infrared technology" or PIR; that's essentially a kind of specialized camera trying to find rapid adjustments to temperatures measured against a credentials temperature).
These more complete type systems are also typically monitored by a central station for a monthly monitoring fee. Lastly, for the people interested in possible telephone line cuts (e-mail, 99% of all alarms systems that are monitored with a central station takes place 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 Internet to a special receiver at the central station.
