    You need to have the ring security system for the door alarms to work. So you would need to pay an additional 250.00. We only want to know when one of rhe kids opens an interior door. So a total waste to us. This information should be on the box. We have several cameras in our home which dont require the security system

      Hi BelindaC.

      Thank you for sharing this feedback with us.

      We understand the importance of having all relevant information prior to purchasing a device. The features and technology provided by Ring devices are incredibly valuable and help provide you with peace of mind about your home security. We are here to provide you with some information to address the issue you mentioned in your review.

      It sounds like there is some misunderstanding regarding the Ring Alarm Contact Sensor (2nd Generation). The Ring Alarm Contact Sensor is an alarm accessory that expands your Ring Alarm system to secure each door and window in your home, so you can get alerts as soon as they open (subscription required).

      The Ring Alarm Contact Sensor is designed to monitor your doors and windows. The contact sensor is made up of two parts: the sensor and the magnet. When installed on your door or window, the sensor can tell if the door or window is open or closed.

      By default, Ring Alarm contact sensors are armed when using both away and home modes. Ring Alarm and all Ring Alarm accessories require a subscription for digital notifications, in-app features, digital arming and disarming, and integration with other Ring, Echo, and third-party products.

      Ring Community was launched in March 2019 to help deliver the most current news and educational information to our customers. This peer-to-peer forum allows our neighbors to share their feedback and experiences to assist each other in resolving their concerns.

      All the best,

      Hi AySd.

      Thank you for taking the time to share your experience with us.

      We understand the importance of being able to monitor motion inside your home while you are away. The Ring Alarm Motion Detector is an important part of the Ring Alarm that gives you peace of mind by triggering your alarm if motion is detected when your system is armed. We would love the opportunity to address any concerns you have with the device.

      It sounds like you are enjoying the features the Ring Alarm Motion Detector has to offer, but you may have some concerns. Review the features below that this device has to offer, and reach out to us if you have any questions!

      Customizable, pet-friendly settings: You can customize motion detection settings to help you avoid false alarms. This is important, especially if you have pets.
      Armed modes: By default, your Ring Alarm Motion Detectors are only armed when using Away mode.
      Installation: Motion detectors should be installed on a wall or corner inside your home 7’6” (2nd Generation) from the floor.
      Entry Delay: If your motion detector placement is set to Entryway, you can customize an Entry Delay that gives you time to disarm your Ring Alarm.
      Bypass Sensors: If a motion detector is offline at the time of arming, you can bypass the motion detector to leave it unarmed.
      Alexa Routines: Use your motion detectors to trigger Alexa routines.
      Alerts and history: Get alerts when motion is detected, and review motion detection history in the Ring app.

      The Ring Motion Detector (2nd generation) is designed to measure both heat and movement over time to help reduce false alarms. You can keep your home or business protected and avoid false alarms by adjusting the Ring Alarm Motion Detector’s motion detection sensitivity settings.

      Hi Game.

      Thank you for taking the time to share your experience with us. We understand the importance of a seamless setup process so that you can begin using your Ring Contact Sensor right away. The features and technology provided by the Ring Alarm Contact Sensor (2nd Gen.) are incredibly valuable and help provide you with peace of mind about your home security. We want to ensure your device is working as intended by providing you with solutions to resolve the concern you mentioned in your review.

      It sounds like the device is not functioning as intended. Monitor movement inside your home when a door or window is opened or closed with Ring Alarm Contact Sensors.

      If your Ring Alarm Contact Sensor (2nd Generation) won't connect or is added as a binary sensor, please follow these steps:

      Remove the contact sensor from its base.
      Ensure that the batteries are installed.
      Open the Ring app.
      Tap the menu (☰).
      Tap "Devices."
      Tap "Alarm Base Station" or "Alarm Pro Base Station."
      Tap "Base Station."
      Tap the "Device Settings" tile.
      Tap "Advanced Options."
      Tap "Z-Wave," then tap "Remove Z-Wave Device."
      Tap "Remove." The Ring app will say, “Remove device, listening for device to remove.”
      Do not tap “Reset Z-Wave Network.” This will remove your entire Ring Alarm network, and you’ll need to reset every device.
      Press and release the pinhole reset button. The device should be removed successfully and can be re-added using the Ring app.

      If the contact sensor is still waiting or attempting to connect to the Ring app, the Ring app is prompting you to perform a factory reset.

      To perform a factory reset, please follow these steps:

      Slide the Ring Alarm Contact Sensor (2nd Gen.) off of its base. Ensure that the batteries are installed.
      Press and hold the pinhole reset button.
      Continue holding down the pinhole reset button until the LED light turns red, then release.
      Re-add the sensor to your Ring Alarm using the Ring app.
      While repeating the setup process, you will be prompted to pull the battery tab. You may have to use a small tool, such as a microscrewdriver, to carefully remove the coin-cell batteries from the casing of your contact sensor, then reinsert them.

      We invite you to reach out to our community if any additional information is needed regarding your question. The Ring Community is our first peer-to-peer community forum, giving our customers the ability to help one another by sharing their feedback and experiences with each other.

      Thank you,

      Hello Scotty,

      ing Alarm Contact Sensors are designed to keep doors and windows in homes and businesses secure. The Contact Sensor is made up of two parts - the Sensor and the Magnet. One part should be mounted on the door or window, the other on the trim. It doesn't matter which one goes where, but you want to make sure the sensor and magnet are mounted close enough together in order to function properly.

      When mounting the Ring Alarm Contact Sensor (1st generation), make sure the notches are lined up. Do not use the Ring Contact Sensor on the side of the door with the Hinge. Also make sure to use Ring Contact Sensors indoors, they not intended for outdoor use. You can install the Ring Contact Sensor using the included mounting tape or screws and anchors.

      The 1st generation sensor and magnet should be no more than 1/2" apart. The 2nd generation Ring Contact sensor and magnet should be no more than 1" apart.

      For any additional installation questions or set up concerns, please feel free to reach out on our community forum at https://community.ring.com/. You can also visit our help site, https://support.ring.com/hc/en-us, for tips & tricks, videos and help articles for all our Ring products.
