Review: Excellent Eufy movement detecting add-on - Works great for movement detection inside the home.
Review: Great Value + Working Well - I purchased two Eufy Motion Sensors for my home and they have proven to be reliable and function perfectly. You will need a working Eufy Homebase, or Homebase 2, in order to use the Eufy Motion Sensors. Adjustments for sensitivity, when the sensors will be active, and how you receive notice of movement, etc., are all made using the Eufy phone App. Adding the motion sensor to your existing system is a snap; I believe it took longer to remove the sensor for the packaging and install the battery than it did to pair the sensor to my Homebase 2. Mounting the sensor to your wall or ceiling is also easy using screws or peel and stick tape, all of which is included. I have a number of Eufy products and, in general, I'm quite happy with them. However, I find Eufy's help and instructions to be either vague, fragmented, non-existent, or just plain wrong. In this case there are no instructions for sensitivity adjustments, etc.. Figuring out how to make those adjustments with your phone App is relatively intuitive, but Eufy leaves it up to you to hunt and peck. Also, the User Manual is incorrect (page 8), where it discusses battery replacement. In my experience this is quite typical of Eufy, which is why I only gave them 4 stars for installation.

## Features

- Protection That Lasts: The included battery provides up to 2 years of power for round-the-clock security.
- Extensive Coverage: Detects motion within a 100° field of view up to 30 feet away—more than enough to secure an entire room of your home. (NOTE: This motion sensor is not waterproof.)
- Adjustable Sensitivity: Tailor the sensitivity of the motion sensor so that it only alerts when humans are in range—rather than your playful pet dog or cat.
- App Alerts: Notifies you as soon as motion is detected, sending a message to your phone via the eufy Security app, no matter where you are.
- Optional 24/7 Protection Service: New optional 24/7 professional monitoring service is now available for 24/7 emergency police, fire and medical response when your alarm system is triggered.
