The Technical Definition of Motion Detectors

By Todd j Scott

The exact definition of a motion detector is a device with a physical mechanism or electronic sensor that measures motion. Some motion detectors have alarms in addition to the more common light.

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.

The most common use for motion detectors is home security. They are highly effective for many different reasons. When placed outside the home, many have a light that goes off at the sign of movement, and others will sound an alarm. This alerts the resident to the presence of someone on their property.

Businesses use motion sensors mounted on the ceiling to protect rooms that are off limits to customers or certain employees. Businesses also use motion sensors that are a form of radar to open doors for customers. These devises use one radar method of detector radar to trigger door mechanisms to open.

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. - 16747
