Home Alarm System is on the top of
every home owner’s priority list apart from the 1080p CCTV installation London. But what is more quintessential
apart from deciding which one to install is what type of sensors they are
equipped with, since they are the major deterrents to burglars and the best
guard against intruders.
Here is a list of 4 Popular Sensors that home alarm systems use to detect an
intruder curate by the top CCTV Installation
London providers, Sure Secure.
Passive Infrared Motion Detectors: Highly functional and affordable
in nature, PIM detectors are the most common detectors that homeowners use.
They are called passive, because for them to operate they don’t need to reflect
and radiate their own energy. They detect activity just with the normal change
in the ambient temperature.
Ultrasonic Detectors: Ultrasonic Detectors function by
transmitting high-frequency sound waves between 25 kHz and 75 kHz, to track any kind of change or to suspect any movement
within a limited space. The frequencies UD transmit are inaudible to human ears
and the alarm is set off when there is any change in the set frequency.
Microwave Detectors: Microwave Detectors follow the same principle of
functioning just like the Ultrasonic Detectors. The only factor segregating the
two is the use of a different kind of wave. Microwave Detectors use
high-frequency radio waves instead of the high-frequency sound waves. The
high-frequency radio waves bear the added advantage of going straight through
the walls that offer the said areas high-security coverage as compared to the
sound waves that bounce off the walls and the ceilings.
Magnetic Switches: Magnetic Switches are equipped in home alarm systems
that are used for securing windows, doors and hidden corners. Their
practicality, functionality and economic rates make them the most popular
choice of the homeowners.
