For those who come home late at night and fumble to find the right keys; for those who have an external garage
that does not have a wired electricity facility and want an external light
source; for those who desire to simply stroll outside the home after dark ...
motion sensor outdoor lights can greatly
enhance both safety and comfort to a home.
The motion of someone walking up to the door automatically turns this bright security light ON for 30 seconds to 10
or so minutes according to the choice of its owner. Normally, motion sensor outdoor
lights have a 180 degree, 30 foot range and two brightness levels. The lights
activate only when movement is detected from up to eight feet away and turn off
automatically after an adjustable delay period. The battery operated motion sensor light which uses
bright white LED (light emitting diode) light can stay on for just about 30 seconds to conserve the battery.
These lights could be used anywhere for night time illumination, be it deck steps, fence gate or indoor
stairwells. These sensor lights are weather proof with plastic housing. They
usually run off batteries which last about a year.
Motion sensor outdoor lights features
The lights are battery operated and there is no wiring or
cords most of the time. The light is brighter than the traditional LED ones. The
lights also have two brightness levels and motion-activated dual lights come on
when movement is detected. The head swivel is adjustable on a 180 degrees
angle. Motion sensor outdoor lights can detect motion up to 30 feet away. There are
dusk/dawn modes, when lights come on at night and turn off during the day.
Motion sensor types
Primarily there are two types of motion sensors, namely active
and passive sensors. Most outdoor lighting uses passive detection. This system
is set to detect the temperature of a human body which radiates infra red
energy between nine and ten micrometers and hence its capacity to detect IR
energy. The heart of a motion sensor is PIR - Pyroelectric Infra Red sensor or Passive Infra Red Detector motion sensor
which uses a solid state chip. Along with a plastic fresnel lens or multi segmented mirrored front, the internal chip with control electronics detects motion across their field of view. The position of these sensors is critical to effective functioning. Even the movement of a cat can trigger it. Passing automobile's headlights can trigger too. On the other hand, if the sensor is positioned in a place facing a source of heat, it can make the sensor less sensitive to detecting human movement. Dust on the mirrors or usually on the fresnel lens which collects the infra red energy can reduce the sensitivity.
The active sensors on the other hand are based on the
premise of being activated. This can happen either by breaking the beam of
light, basic radar signal or ultrasonic wave. A change in the return of the energy
to the unit by a source of energy triggers the sensor. These types of sensors
are rarely used in home motion sensor outdoor lighting facilities.
Remote controlled motion sensors
The motion sensors can also be remote controlled which
offers added safety and convenience. This system carries all the features like
any other motion sensor outdoor light with an additional remote control to
activate the light from inside the house.
Solar energy charged motion sensors
The solar sensor light is another solution to provide
practical light for security reasons. This light turns on automatically when
the motion is detected and off after a minute. Since the battery is powered
solely by sunlight, there are no wires required. This is ideal for emergency
use as one can simply rely on this handy object all year round.
Solar powered units also feature backup battery packs which
require no hard wiring. Solar powered units provide a feeling of comfort and
security at night and this light fixture is a popular choice for its efficiency
and versatility.
Motion sensor outdoor lighting
The stealth motion sensor models come with twin precision die cast. This is suitable for wet locations as it comes with deluxe shield for floods, pre-wired and assembled on
a universal cover plate. The surge protection facility can withstand up to 6000
volts. There is a wide sensitivity control adjustable from 100 to 30%. The
temperature compensation facility is sensitive to adjust automatically for
consistent detection in hot and cold ambient temperatures. False triggers are
minimized due to the availability of advanced detection logic. It has a fully
adjustable 24 hour operation photoelectric control device.
Dual flood light
with built-in motion sensor is the perfect solution for an existing flood light
outdoor. Another ability of this motion sensor flood light is to control
additional lights. If this light is enabled, it can trigger other lights at
home and in the yard whenever movement is detected. This way the entire
interior and exterior of a home automatically lights up during an emergency
situation.
Benefits of motion sensor outdoor lighting
Motion sensor outdoor lights with
bright LEDs make a great safety feature to steps and entrances of homes. It is
often construed as a first line of defense against any house break or home
intrusion.
This is an inexpensive source of
installing security lighting. Motion sensors are proven to be economical as the
light only stays on for the length of time set by the owner. One need not worry
about turning a switch on and having to remember to turn it off again as it is
taken care of.
Most packages of motion sensor
outdoor lighting come pre-wired and they can be installed as a do-it-yourself
project without much expense. Most of them have the motion sensor mounted below
the primary two security lights to have the largest field of view possible.
This motion triggered light systems also come with the
feature to be manually turned on by the home owner for general lighting. Strategically
placed motion sensor outdoor lighting can provide peace of mind that no
intruder can pass by the home unnoticed.
