    • 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. ... show more

    • Good enough
Review Image by Malibu Shary Malibu Shary
These are a good deal for the price and only work with their own system. They're not compatible with anything else. They are tiny and fit in my decor. They look good. Functionality wise, you can actually set them on the app so that the LED does not blink every time there is motion. I have to look around to find it in the app. They stated battery life is good. Detection range is kind of difficult. On the edges it's not so good. So I pointed it down from a higher place and get most of the area I need covered ... show more

    • Easy install
Eufy has made an ease of using home security system and have been using them for awhile now. Over a year and no battery change yet.

    • Motion Sensor with Eufy Reliability, Lacks Alexa integration
As with all Eufy products, the motion sensor too comes with a solid build. My initial impression on build quality, ease of pairing to home base 3, and sensing accuracy is quite good. I have given only 3 stars because the device is restricted to its own product circle ie: work with eufy security system or cameras only. The sensor, unlike many in the market, does not support alexa triggers. If it did, a whole plethora of other brands of alexa supported smart devices could br linked to work with this sensor. I sincerely hope Eufy considers the larger use case by enabling Alexa integration of this sensor. I am unable to comment on the battery life span as its too early to do so. ... show more

    • Works well outdoors (so far) with Eufy s220 camera
Thought I would try to see if these work outdoors. I have one sensor on the downspout that runs under the side of the building with double sided tape along with the bracket. The other sensor is taped on the downspout with double sided tape on its side. So far both are working well (fingers crossed) and it's been outside for a few months. I do not have these sensors out in the open (no direct sun and rain) so this could be why they are still working. Both sensors are linked to the Eufy s220 cameras. They help the cameras catch motion better imo. ... show more

    • Working Fine Outdoors
Am using this motion sensor to trigger a doorbell camera and also a second camera mounted outside on the garage. Since this unit is intended for indoor use only, used clear tape to seal potential water infiltration spots such as the battery compartment cover. Also, mounted the unit under garage eaves so it’s mostly out of the rain. Motion sensor has been out in the elements for a couple months including heavy rains and a couple snow showers, and it continues to trigger the two cameras. ... show more
