Security System Intro 2
Security systems have become standard equipment in many businesses,
and they are becoming increasingly common in private homes as
well. When shopping for security systems, you will discover
that there is a wide variety of options available. security
systems range from do-it-yourself installation kits to sophisticated
whole-house security networks that must be installed by professionals.
Even if you choose one of the available high-tech security systems,
the basic concept is the same. It was made for protection and
it can make you feel extra safe. In order to grasp the functions
of various security systems, you must start with the Brain or the
Control Panel. This device comes with all security systems and
its main function is to alert output devices when receiving
signals from security alarm sensors.
The Key Pad allows you to interact with the security systems;
with its help you can turn you security alarm on and off. It
is placed by the main entry and as security systems have evolved
it has become much easier to use. This device made especially
for burglar security systems has night time options with illuminated
screens and speed use emergency, just by pushing a single button.
Many security systems have also remote control key pads, which
are lightweight and portable.
Contacts are additional features of all the available security systems on the market. They detect the opening and closing of
doors and windows. This device alerts the control panel of security systems when the magnetic bond between the door frame and the
door is broken. There are three types of contacts made for burglar
security systems. Recessed contacts are hidden in the window tracks
and door jams. They are more complicated to install unless the
burglar security systems are placed during the construction phase
of one’s home. Surface mounted contacts are visible when
the door or windows are closed and they come in various sizes
and colors to blend in. Roller ball contacts are the latest
hit on the burglar security systems market; they are installed
in the hinge side of the door jam and they are extremely efficient.
All types of contacts can be hardwired directly to the control
panel of the burglar security systems or you can choose a wireless
version.
Glass break detectors are special made for burglar security systems.
They detect the breaking of windows or glass doors by listening
for the specific sound frequency of breaking glass. This kind
of detectors are a very attractive feature of many burglar security systems.
The most important and widely used sensors for burglar security systems are motion detectors. They are able to detect movement
within a pre-set range of a given enviroment and there are many
types available on the market. Still, the one that most burglar
security systems have are infrared motion detectors. They use infrared
or passive infrared sensors to alert the security system to
certain changes in the levels of heat and/or movement. The device
is extra tricky, it sends invisible fingers out into the covered
area in several layers. It even has a microchip that adjusts
the device for slow and methodical temperature changes.
Still, there are some drawbacks to these devices custom made
for burglar security systems. This technology is not able to see
through walls or windows as they consider touching one of them
as their final destination. Also, the beams project forward
only and does not bend around corners. There are minor setbacks
compared to what level of safety can this device can confer.
Other types of motion detectors offered by several burglar
security systems are the one which can be mounted in corners or
on the ceiling. The first are widely used and they are included
in many burglar security systems as primary features. The second
offer full 360° coverage and they are useful in rooms in
which the corner motion detectors are blocked by doors or shelves.
