Presence Entry Sensor

Stick them onto your front door to monitor and get alerted when it opens.  This is a great way to get notified when your door is opened. You can set up rules that engage or disengage other sensors and devices, like lights or other security cameras. 

Presence Motion Detector

This sensor adds an extra layer of security giving you during day or dark motion detection. This device is made to be inside or away from weather conditions and you can also set up custom rules to notify you, activate other sensors and devices. All Presence Security sensors can be aligned with your location through Geofencing. This helps you set custom rules when you are away or at home. 

Presence Touch Sensor

Imagine if someone knocks on your door when you are in your backyard or another spot in your home where you can't hear them knocking. Attach our Presence Touch Sensor to the interior side of your door in the area where people knock outside. In your custom rules name the sensor 'Someone is Knocking at Door' and to notify you and activate your connected devices!
