Easy set up. *by A***Z on January 8, 2026* These work very well. They are excellent. Set up is easy as can be. You must have the Eufy hub for the audible alarm. The coverage are is more than sufficient. It does not pick up on small animals. ### ⭐⭐⭐⭐⭐ Great Value + Working Well *by R***E on September 14, 2022* 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. ## Frequently Bought Together - eufy Security Motion Sensor, Home Alarm System, 100° Coverage, 30 ft Detection Range, 2-Year Battery Life, Adjustable Sensitivity, HomeBase Required, Optional 24/7 Protection Service, Home Security - eufy Security Entry Sensor, Detects Opened and Closed Doors or Windows, Door Monitoring, Sends Alerts, Triggers Siren, 2-Year Battery Life, Indoor Use Only, Requires HomeBase, 24/7 Monitoring Optional - eufy Security 5-Piece Home Alarm Kit, Home Security System, Keypad, Motion Sensor, 2 Entry Sensors, Home Alarm System, Control from The App, Links with eufyCam, Optional 24/7 Protection --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/201989788-motion-sensor-home-alarm-system-100-coverage-30-ft-detection](https://www.desertcart.ni/products/201989788-motion-sensor-home-alarm-system-100-coverage-30-ft-detection) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-08*
