Works With
The Ring Alarm Motion Detector (2nd Gen) is a solid, easy-to-use choice for existing Ring Alarm users seeking reliable motion detection with long battery life but is less suitable for those needing advanced features or pet-friendly sensors.
The Ring Alarm Motion Detector (2nd Gen) 2-Pack is designed primarily for users already invested in the Ring ecosystem, especially those using the Ring Alarm security system and Amazon Alexa devices. It does a solid job detecting motion with decent accuracy and integrates smoothly with Ring's app, allowing for customizable alerts and automation. The 2nd generation offers improved battery life over the first, typically lasting around 2 years on a single set of batteries, which is convenient for low-maintenance use. However, the sensor has a relatively narrow detection range compared to some competitors, roughly 30 feet, and can occasionally trigger false alarms from pets or moving curtains. It lacks some advanced features like pet immunity or adjustable sensitivity levels found in higher-end models. Installation is straightforward but requires pairing with the Ring base station, so it’s not a standalone product. This makes it less suitable for users wanting a simple, standalone motion sensor or those not using Ring’s ecosystem. If you want a basic, reliable motion detector that fits into a broader Ring security setup, this is a good choice. But if you need more advanced detection options or multi-ecosystem compatibility, you might want to look elsewhere. Overall, it’s best for Ring Alarm users who want easy integration and decent battery life, but not ideal if you want more granular control or broader smart home compatibility.

Compared to the Samsung SmartThings Motion Sensor, the Ring detector offers better integration with Amazon Alexa but lacks SmartThings’ broader ecosystem compatibility and more customizable sensitivity settings. The Ring sensor’s battery life is comparable but slightly better than the SmartThings model’s typical 1-1.5 years. Compared to the Philips Hue Motion Sensor, Ring’s device is more security-focused and integrates with Ring Alarm, whereas Hue’s sensor is more geared toward lighting automation with faster response times but shorter battery life (around 6 months). The Ring sensor’s main trade-off is its limited ecosystem and fewer advanced features compared to these competitors.
Installation is relatively easy, rated around 2 out of 5 in difficulty. It typically takes 10-15 minutes per sensor. You just need to mount it with included adhesive strips or screws and pair it to the Ring Alarm base station via the app. No special tools are required unless you choose to screw it in. Common issues include pairing delays or needing to reset the sensor if it doesn’t connect initially. Professional installation is generally not necessary unless you’re unfamiliar with smart home devices.
In daily use, the Ring Alarm Motion Detector is generally reliable with prompt notifications through the Ring app. Response times are usually under a second, which is adequate for home security alerts. Users report occasional false alarms triggered by pets or environmental factors like sunlight or curtains moving. The app interface is straightforward but somewhat basic compared to competitors, with limited customization for motion sensitivity. Battery life is strong, with typical usage lasting around 2 years on standard AA batteries before replacement is needed.
- False alarms triggered by pets or moving curtains
- Occasional difficulty pairing with the Ring base station
- Limited customization for motion sensitivity
- Narrow detection range compared to competitors
- No pet immunity feature
