Smart Security Door And Window Contact Sensors
Expand Your Smart Home Security System Coverage When You Add Indoor Motion Sensors Throughout The House. Receive Alerts When Motion Is Detected And The House Should Be Empty. Smart Detection Recognizes Pets And Other Background Motion And Does Not Send Alerts.
A Motion Sensor (Or Motion Detector) Is The Linchpin Of Your Security System, Because It's The Main Device That Detects When Someone Is In Your Home When They Shouldn't Be. A Motion Sensor Uses One Or Multiple Technologies To Detect Movement In An Area.
Contact Sensors Are Most Often Used As Part Of Smart Security Systems, Put On Doors And Windows To Tell If They've Been Opened When They Shouldn't Have. But They're Also Really Useful For Knowing If Anything Has Been Opened Or Closed - Blinds, Fridges, Drawers, Garage Doors, Doggie Doors, Medicine Cabinets, You Name It. If It Opens And Closes You Can Stick A Contact Sensor On It.
Motion sensors work by sending out signals; When the signals are disrupted or tripped the motion sensor triggers an alarm, alert, or programmed automation.
Some devices use dual technology, meaning two different sensors would need to be tripped in order to trigger an alarm, reducing false alarms.
Many indoor and outdoor security cameras also have video motion detection available. This allows you to use video as part of your security system but doesn’t require cameras to record 24/7 and bog down servers or cloud storage with hours of footage.
Since you don’t really need or want cameras recording your personal activity within the privacy of your own home you can also use Bluetooth geofencing capabilities to turn video recording off when your smartphone is within the geofence.
irst and foremost, you want your motion sensor in an area that will detect an intruder. So, it should be placed near an entrance door or near a room that holds valuables like a study or master bedroom. Be sure to place the motion sensor in an area that you know an intruder would have to cross or in “choke-points” like hallways or stairwells.
You can also use motion sensors for turning on lights or sounding doorbells, in these instances it would not trigger an alarm, but a different type of smart home function.
