A:Answer Hello Shelly,
Great question. Yes, the Ring Alarm Contact Sensor needs a Ring Alarm Base Station to work as intended. Please see our help center article for more information: https://support.ring.com/hc/en-us/articles/360039497552-Ring-Alarm-Contact-Sensor-Setup-and-Use.
Additionally, if you have not already, please check out our Ring Community forum where other Ring users, like yourself, have an open discussion platform to share their experiences, as well as solutions to issues experienced: https://community.ring.com/.
Thank you, Jamila at Ring.
