When looking for the best wireless motion detector, you should consider your needs and for what applications you are looking to use such a detector. Some basic considerations that can help narrow your search would be whether you are planning to use the device indoors or out, any pets you might have, what type of other system you may want the device to work with, and whether you want the device for security or other purposes. The right wireless motion detector for you should satisfy your needs while also potentially providing some uses you may not have considered.
A wireless motion detector is a device that detects any motion within a certain range and then activates a number of different potential systems, depending on what you wish to use it for. These can be used for home security, to activate lights in areas such as walkways and driveways for easier navigation in the dark, or for a number of other applications. One of the first things you should consider is whether you wish to use your wireless motion detector indoors or outside.
If you are planning on using the device outside, then you should find one that is weather resistant and can handle the elements. An indoor wireless motion detector will likely not be as durable and may also have a shorter range. You should also consider specific types, such as those that use infrared to pick up only heat-producing animals, and will not be triggered by swaying tree branches or passing cars.
Some types of infrared detectors can even ignore smaller animals by only activating when detecting an object with higher body heat levels. This allows a security system using a wireless motion detector either inside or outside to only be triggered by a person, and not by a small house pet or animals such as raccoons and squirrels. You should also consider what type of system you want the detector to function with.
For example, if you want a wireless motion detector for home security, then you may need to purchase the detector from a security company as part of a larger package. Some detectors can be used with a self-contained alarm system that will trigger numerous lights throughout a house and emit a loud, piercing sound to alert others to a potential intruder. Other systems use motion detectors as a way to trigger an alarm and notify a contracted company of a potential security situation, though these often require a monthly or yearly service fee.
Some types of wireless motion detector even have secured screws on the battery compartment to prevent tampering from possible intruders. Other detectors can be used as part of a simple lighting system, to activate lights and illuminate dark walkways or driveways for easier navigation. These may be less expensive than other systems and will likely connect to existing home lighting.
