Is A Motion Detecting Alarm A Good Choice For My Home?
A motion detecting alarm is one that sounds when something moves past its sensors. They can be set to chime and simply alert you that someone is near, or they can give off a normal security alarm sound. Motion alarms are very reliable, and the ranges at which they detect movement vary greatly. Some alarms can detect movement at as little as 20 feet, others at as far as 800 feet. Also, in addition to outdoors, motion alarms can be installed inside your home for added security (in case of a break in). T
he sensors that these devices use to detect motion are infrared. Some motion alarms are battery operated, utilizing 9 volt batteries, and come with a wireless remote control to disarm them when desired, especially if the user is elderly or the alarm is mounted up high. The remote can be kept on the user’s keychain or lanyard, also, to prevent it from being lost or misplaced. After arming a motion detecting alarm, there is a time allowance of a few seconds for the user to leave the building or home before the sensor turns on, so that it does not detect your own movement by mistake. This feature helps to prevent false alarms.
Most motion alarms come with an LED indicator that lets the user know when the battery is low, so that they have time to install a new one and are not unpleasantly surprised with it does not sound as desired. Not knowing a battery has died is very dangerous if you are using the alarm for security purposes. Some alarms, in addition to being mountable, can be placed beneath the doors of your home. These versions of the device are designed to be portable so the user can take them to hotels, night shifts at work, and other places besides their own home.
