Probrico DS211 Smart Door Sensor Alarm: Instant Smart Alerts via app notifications
This Probrico Smart Door Sensor is for the parent who needs to know the moment a child comes home from school. While many sensors focus on security, this one provides a quiet sense of connection, letting you confirm safe arrivals without constant calls.
You get instant smartphone alerts when the door opens or closes, so you see the notification before your child even texts. The two-way audio and Alexa compatibility let you greet them or check in through your indoor camera setup. Installation is simple with peel-and-stick adhesive, and it works on 2.4GHz WiFi for reliable home security. Pair it with a Probrico lock for auto-locking when the door closes, adding an extra layer of safety.
