Where to install motion sensors?

A motion sensor is what most people consider to be one the forefront of home security and this is rightfully so. Motion sensor (or otherwise known as a motion detector) is the main device in a home alarm system that detects the presence of an intruder in your home. It utilizes one or more technologies to detect movement in any area of your house. When the sensor is triggered, the device alerts the control panel of your security system. Then, it sends signals to you and your professional monitoring center of the potential break-in.

Apart from detecting potential break-ins, a motion sensor can also trigger a chime sound when someone, says the delivery guy, is at your front door. You can prevent kids from entering a restricted area in your house by alerting you when they enter the said area. Pair a motion sensor with a smart light could also save energy in areas that are not used frequently, e.g. kitchen, basement or the walk-way. 

With that said, simply installing a motion sensor is not enough. It is important to place the motion sensors in the right place to reap its maximum benefits.


Away from heat 

Keep motion sensors 3 to 5 meters away from heating vents, where the sunlight shines in, and radiators.

by intruders. Common points of home break-ins are the front doors, back doors, and windows.

But, by the time your pet reaches the top, the sensor will be seeing a tiger.
