Works With
The Ring Alarm Motion Detector (2nd Gen) is a solid, easy-to-install sensor best suited for Ring users seeking basic motion detection but falls short for those needing longer range or fewer false alarms.
The Ring Alarm Motion Detector (2nd Gen) is a straightforward motion sensor designed primarily for users already invested in the Ring ecosystem, especially those using the Ring Alarm security system. It does a solid job detecting movement within its range and integrates seamlessly with Amazon Alexa for voice alerts and automation. Setup is generally quick, and the device uses battery power, which means you don’t have to worry about wiring. However, its detection range is somewhat limited compared to competitors like the Samsung SmartThings Motion Sensor, and it occasionally reports false positives, especially with pets. The sensor’s battery life is decent but not exceptional, typically lasting around 1-2 years depending on usage. It’s perfect for homeowners who want a simple, reliable motion detector that works well with Ring’s security hub and Alexa but may not satisfy those looking for advanced features like temperature sensing or multi-sensor capabilities. If you’re not already in the Ring ecosystem or need a sensor with a longer range and fewer false alarms, you might want to consider alternatives. Overall, it’s a solid choice for basic motion detection but has limitations in range and occasional sensitivity issues that could frustrate some users.

Connectivity
Requires Hub
Ring Alarm Base Station
Requires Ring Alarm Base Station hub; no Apple HomeKit or Matter support; limited to Ring ecosystem.
Compared to the Samsung SmartThings Motion Sensor, the Ring detector offers tighter integration with Alexa and Ring’s security system but lacks the multi-sensor capabilities and longer detection range of the SmartThings device. The Wyze Motion Sensor is cheaper and offers similar basic functionality but requires a separate hub and doesn’t integrate as smoothly with Alexa. The Ring sensor’s main trade-off is its limited range and occasional false alarms versus competitors that provide more features or better accuracy but may need more complex setups or additional hubs.
Installation is straightforward with a difficulty rating of 2 out of 5. It typically takes about 10-15 minutes using the included mounting hardware and a screwdriver. No hardwiring is needed since it runs on batteries. The main challenge users face is finding an optimal placement to avoid false triggers. Professional installation is generally not necessary unless integrating into a more complex security system.
In daily use, the Ring Motion Detector is generally reliable with response times around 1-2 seconds. The Ring app is user-friendly but can occasionally lag or fail to update sensor status promptly. Battery life usually lasts 1-2 years, but heavy usage or frequent alerts can drain it faster. Some users report false alarms triggered by pets or moving curtains, which can be annoying. Overall, it performs well within its intended scope but isn’t perfect for environments with many potential false triggers.

Homeowners looking to add motion detection to their Ring security system.
Consider purchasing a Ring Alarm system for full functionality.
Buy this sensor if you’re already using Ring Alarm or Alexa devices to ensure smooth integration. Pair it with other Ring sensors for a cohesive security setup. Avoid placing it near pets or curtains to reduce false alarms. Don’t expect advanced features like multi-sensing or extended range. If you need those, consider competitors like SmartThings or Wyze.
