    Q: Can these be used outdoors or are they for indoors only?

    A: Good question. I suppose you could but I doubt they’re weatherproof. I think the Ring Cameras would work better for that. Most cameras come with a motion detector built in.

    Q: Is this product a good design for the hearing impaired?

    A: Hi Consentida. Good question. The Ring Alarm Motion Detector is designed to monitor a room or area inside your home for heat and movement. When armed, the Motion Detector will trigger your Ring Alarm when heat and movement are detected. 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. All the best, Nicole from Ring.

    Q: I would like to use this as a way of monitoring the movements or lack of movement of my 95 year old father that lives alone. Can this work as a stand alone device that will text me each time motion is detected?

    A: Hello, Great question. No, the Ring Alarm Motion Detector (2nd Gen) will not work as a standalone product. The Ring Alarm Motion Detector connects to your Ring Alarm and is designed to monitor a room or area inside your home for heat and movement. When armed, the motion detector will trigger your Ring Alarm when heat and movement are detected.

    Q: I don't have a ring alarm system but can I use this to activate my linked ring lights?

    A: Hi CallmeMrR. Thank you for your question today! No, the Ring Alarm Motion Detector requires the Ring Alarm Base Station in order to setup to the Ring app and start detecting motion. Although, the Ring Smart Lighting Motion Detector is our Motion detector that's designed to be linked with our Ring lights to activate them with motion. The Ring Smart Lighting Motion Detector is also designed for outdoor use. The Ring Smart Lighting Motion detector does require a bridge device in order to setup and link with your Ring lights. If any additional information is needed regarding the Ring Alarm Motion Detector, please reach out to our community.

Sincerely, Matthew from Ring.

    Q: Are the holes on the back of the motion detector for screws so that you can screw the motion detector into drywall? I don’t want to mount it into the wall all using the adhesive backing strip.

    A: Hi Mounting. Thank you for taking the time to reach out to us with your question. We do not recommend using screws to mount the Ring Alarm Motion Detector as it can inhibit the performance of the device. For optimal performance, we advise peeling the tape from the adhesive pads and adhearing the device to a clean and dry wall, 7-8 feet from the ground. If any additional information is needed regarding your question, please reach out to our community.

Thank you, Melissa from Ring.

    Q: Can the motion sensor be mounted onto the wall using screws? If not, does Ring sell a mounting bracket that can be screwed onto the wall for the motion sensor? I read quite a few reviews on Amazon of people complaining about the mounting tape wearing off

    A: Hi Matt. Thanks for asking. The Ring Alarm Motion Detector (2nd Gen) does not have a mounting bracket. Mounting tape can be found on the back of the detector. Ensure the mounting surface is clean and dry before peeling the backing off of the adhesive strip. Visit our support center for more information on setting up and installing your motion detector.

    Q: Can you connect this sensor to an Alexa without buying the security hub?

    A: Hi dizzy. Thank you for asking. A Ring base station is required in order to use the Ring Alarm Motion Detector. The Base Station connects all your Ring Alarm security devices, Ring Video Doorbells, Security Cameras, and other smart devices. It monitors your sensors in order to trigger break-in or fire alarms while supporting cellular and battery backup if your internet or power go out.

    Q: I’m getting the security system can I easily add extra motion sensors that are separate from the system package? Are they easy to hook up?

    A: yes easy to add to ring system. just scan the QR code on the device to add it to your system.
