Ring Contact Sensor

Your Ring Alarm kit only came with one contact sensor, but chances are you've got more than one entry point in your home. Add additional contact sensors and get real-time security alerts on your mobile device whenever a door or window opens at home. They mount easily to any door or window frame, and their tamper-resistant design and long battery life mean you can rest a little easier. If you have a Ring Protect Plus plan, the monitoring center will contact you when a contact sensor is triggered. If they can't reach you or the other listed emergency contacts, they will dispatch emergency responders to your address.
