Motion sensors, or commonly known as motion detectors, have become an integral part of security and home automation systems.
They can detect sound easily, producing alarm as soon as image record devices capture an image.
A lot of people have started investing in this product as the feasibility that it offers is just outstanding.
Catching a glimpse of someone movement is something that can really stand as a great means in maintenance of security.
Drive way sensors are the most common motion sensor devices used in commercial establishments, offices and homes.
Motion sensor lighting has been widely used to light up passage or rooms when necessary and switch off when not needed.
Wireless motion detectors are hugely popular in the arena of home security devices.
A lot of museums have this technology.
For the high value possessions that they hold, human security is not sufficient.
Therefore the motion sensors come across as a very good option to invest in.
Let us now get into more details of motion detectors, how they function, and how much sense there is in investing in such devices.
Functioning Principles of Motion Detectors There are two major principles on which motion sensors work - again, it depends on the type of sensor.
The two major types available in the market are dual technology sensor and passive infrared sensor.
The latter is most commonly used.
It needs both movement and heat to set off, eliminating false alarms caused by plants, vertical blinds and likewise.
Its driveway motion sensor enables opening of garage door, turning the lights off if it is dark and closing the door on exit.
It also opens the gate on return, switching the driveway lights, the front yard lights and the flood lights for you.
Motion detector types There are various types of motion sensors, right from the most sophisticated laser beams to the simplest infrared detectors.
These sensors detect the presence of any motion in the area it operates.
So, when someone tries to come into your area, you can be sure that the motion sensor will detect the movement.
This way you can be updated about the moves of the bad guys and bring them down.
It could either be location specific or one spread over a large area.
For instance, door front is a specific location.
If someone steps on the doormat, it triggers an alarm.
Area usually indicates something which moves within the view of a particular sensor.
It is bigger in size than location specific sensors.
Simple electronic heat sensitive devices are used in both cases.
