The Technical Definition of Motion Detectors

By Todd j Scott

Chances are we have all come in contact with motion detectors at some point in our lives. They can be found in a variety of different places and are used for many different reasons. Even though you may have been near one in the past, you may not be familiar with the exact definition.

It is very likely that you have run across many motion sensors in your life, whether you know it or not. Many different places employ the use of motion sensors for many different reasons. One type uses motion detector radar to alert door sensors when individuals come near them, which "tells" an attached mechanism to open the door.

Now that you are familiar with motion detectors, let's explore the different types that exist. There are actually several different types of detectors. The internet lists all different types of alarms, including infrared. These identify heat producing objects. This particular kind would keep the light and alarm from turning on if an inanimate object flew by.

If you are interested in something for inside your home or office for security reasons, then the ceiling mount type is an option. These cordless radar motion detectors can cover the entire room when mounted on the ceiling.

There are many different types of motion detectors, and not all of them produce the same results. A quick search on the internet reveals many different types of alarms. One modification to the traditional motion detector is the infrared detector. This alarm only sounds when a live creature passes through the sensor, because it only reads body heat.

Ceiling alarms are a useful tool for indoor security reasons, because they can "see" the whole room at once. Another type of motion sensor that is used by businesses is one that will open doors for their patrons to enter their establishment. This type uses detector radar methods to trigger a mechanism to open the door when customers approach.

There are other, more creative, uses for motion detectors. They can be used with small children or the elderly to sense when they have left their bedroom at night. They can be used on outside doors, so that you will know when your teenager is sneaking in or out at night. Another great use for motion alarms is as a sensor by the pool, to allow you to know when some is near that area. It is a good idea to consider having alarms like these placed in your home. You will feel much safer knowing what is happening on your property. - 15254
