  • Reliable and Accurate Motion Detection – A Must-Have for Home Security!
Configuration: 1 Pack
The Ring Alarm Motion Detector has been a fantastic addition to my home security system. It’s incredibly reliable and accurate, providing peace of mind by detecting motion in and around my home with ease. The setup was straightforward, and it synced perfectly with my Ring Alarm system. What I really appreciate is how sensitive yet customizable it is. I can adjust the settings to suit my needs—whether I need more or less sensitivity in certain areas, the Ring app makes it easy to configure. I also love the pet-friendly feature—it detects human motion while avoiding false alarms from pets, which is a big plus for pet owners. The battery life has been great, and I haven’t had to change the batteries yet. The motion detection range is perfect for my space, and I’ve been impressed with how quickly the alerts come through on my phone when motion is detected. It’s also nice that the design is discreet, fitting seamlessly into my home’s decor. Overall, I highly recommend the Ring Alarm Motion Detector to anyone looking to enhance their home security. It’s accurate, easy to set up, and works perfectly with the rest of the Ring system. Definitely a must-have for anyone serious about keeping their home safe! ... show more

  • Works well with the right batteries
Configuration: 1 Pack
It works well but not with the Amazon Basics Rechargeable AA NiMH High-Capacity Batteries (2400 mAh, with the grey tops). I think they don't fit right because the motion sensor doesn't get power. So I use either the regular Amazon Basics Rechargeable AA Batteries (2000 mAh, with the black tops), or standard Eneloop 2100 mAh batteries. ... show more

  • Reliable and Easy-to-Install Motion Detector
Configuration: 1 Pack
The Ring Alarm Motion Detector has been a reliable addition to my home security system. This motion detector is easy to install, and it integrates seamlessly with the Ring Alarm system. The setup process was straightforward, and the device connected to the system without any issues. One of the standout features is its sensitivity. It accurately detects motion without triggering false alarms from pets or other minor movements. The device also has a sleek design that blends well with my home decor, making it unobtrusive yet effective. The only minor downside is that it requires a Ring Alarm system to function, so it's not a standalone device. However, if you already have the Ring system, this motion detector is an excellent addition. Overall, the Ring Alarm Motion Detector is a highly recommended product for enhancing home security. Its reliability, ease of installation, and accurate motion detection make it an essential component of a comprehensive security setup. ... show more
