Motion sensor lighting are used for a variety of purposes. Some of its uses are illustrated here. They are used for security purposes for instance. The bright lights can scare off possible intruders. This is done by detecting their movements around the motion detectors, and creating an alert by switching the bright lights on. It is also helpful in other ways. For instance, if you have just come back home in the night, you do not have to struggle with putting your keys into the keyhole; the lights will immediately make the keyhole clearly visible. You also will not stumble or trip around the stairs in front of your doors in the darkness. Additionally, it automatically helps to save electricity, in that it naturally turns off the lights when there is no movement outside the door.
Some of the very popular brands in this product category are Nightguardian and Leviton. Other popular brands include EML and Heath Zenith etc. Motion sensor lights come with both the auto-on and auto-off facilities, as well as the manual-on and manual-off capabilities. This is good because this way, if you decide to use the light indoors, the light will not be automatically turned on or off due to the presence or absence of movement around it respectively. Being able to manually override is thus useful both in terms of switching on and off when required.
Of course, irrespective of whether the light is used outside or inside the house, the manual overriding feature must be installed inside the house, so that it cannot be manipulated by an outsider. A capability to adjust the time-frame, for which the light will remain on upon detecting movement, is also available. You can also use the remote motion type of detectors. These detectors are specialized detectors that can be used to detect absolutely any movement in a far away distance from the actual installation location of the light. In this case, radio waves are employed for instant wireless communication with the switch, to turn on the lights when the intruder or incoming person or vehicle or any moving object comes within the set remote distance range. With these detectors you can avail between 90 degree to complete, 360 degree, surround footprint worth of detection range.
If you feel that some areas are safe enough or unused enough to generate only false alarm, in the event of any local movement in that location, then you can deactivate that angle of coverage by simply taping that much angle of the sensor with a black tape. Reaction times might be lagged during temperature falls, due to changing weather. Hence, the threshold minimum operating temperatures must be maintained around the sensors. Motion sensor lights are available in regular lights, porch lights as well as flood lights variety. You can also save on costs by going for the solar powered lights or battery powered LED lights etc.
