We're not sure how the competition does it, but here at Dome we use only the highest quality farm fresh reed switches in our Door/Window Sensor.
A reed switch is a small electrical switch that stays closed in the presence of a magnetic field.
When the magnetic field is removed, the switch opens. A small but powerful magnet included with each and every Door/Window Sensor will actuate the switch every time a door is opened or closed.
You might be asking yourself "Couldn't I defeat a door sensor by just sticking a magnet to it?" Of course you can! But don't get any ideas, a careful consumer would have also purchased a Dome Motion Detector that won't be so easily defeated!
