With the advancement of technology there
are many new security systems that are available of the market.
An important part of many of these systems is a motion detector
component. There are many different types of motion
detectors that use different technology. For example, infrared motion
detectors have a sensor that detects infrared radiation produces
by humans. This is just an example, as many other technologies
are used to detect movement. Another example is a detector
that produces a beam of light and has a photo sensor at the
receiving end. If a beam of light is broken, the motion is
detected. Ultrasonic waves can also be used to detect movement.
The wave is bounced of some type of item and the receiver checks
for the wave’s echo. This article will provide some examples
of the security systems where motion detectors are used and
will describe some of the benefits that these motion detectors
provide for these security systems. The prices of motion sensors
vary a lot and are not discussed here.
The
most common example where motion detectors are used is
in various types of alarm systems. The concept is simple. In
addition to triggering an alarm when the incorrect code is
entered through the alarm control panel, the alarm system is
activated when one of the motion detectors senses an unauthorized
movement inside the house. Motion detectors can also be installed
outside of the house in cases when you also want to guard your
garden or yard. Most of the detectors are battery operated
and don’t require a direct power feed. However, it is very
important to make sure that the batteries are always checked
and replaced often. Also, with the advancement of wireless
technology, many of the motion detectors are produced in a
wireless version nowadays. That means that there are no wires
connecting the motion detector to the alarm system. Detectors
are less visible and still can activate your alarm system by
sending a wireless signal to the system when any movement is
detected.
Motion
detectors are also used in various video surveillance technologies. The reason for this is to save the storage space
and record only during the time when motion is detected. Video
surveillance systems use several motion detection techniques.
The first technique is similar to the one used in the alarm
systems. There are separate motion detectors inside or outside
that send a signal to the video surveillance system when any
movement is detected. The detection can also be done on a software
level. For example, a video stream is sent to the receiver
that is connected to the computer. The software analyzes the
incoming video stream and if any change in the picture (movement)
is detected, activates the recording process. There are other
techniques that can be used. Sometimes even two or more motion
detection techniques are used at the same time.
Motion
detectors are also used for the outside motion sensor light
system. The system turns the light on when any movement
is detected by the motion sensor. This will allow you to see
clearly who is approaching your house. This also serves a double
purpose by allowing you to see the parkway and the door steps
when you approach your house at night. The type of motion detector
that produces a beam of light and detects motion when beam
of light is broken is commonly used in the garage door sensors,
not allowing the garage door to close when motion is detected
under the door. There are many examples of other types of security
systems that use motion detectors. Even more advanced motion
detection systems are created for business needs or for the
locations where something very expensive is stored.
Motion
detectors usually come with the purchased security system. However, you can purchase them separately to upgrade
your system. It is preferable that you hire a professional
to install any part of the security system, including motion
detectors. Still, there are many “do it yourself” kits that
will allow you to install these detectors yourself. There are
also many guides and manuals that provide detailed description
of each model of motion detectors and their installation and
configuration process.
