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.

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.

Eufy Security Review I’ve put a lot of time into researching alarm systems. I used to work for an alarm system company and believe in home managed “smart” systems. Eufy caught my eye after a lot of great reviews on the doorbell. I decided to keep all my sensors and cameras within the same system to keep it easier to manage. After having it for 8 months now: I’ll go over the pros and cons of this system from my experience. My system includes: 2k Wireless Doorbell Cam, Door/window sensors, Motion sensors, Eufycam 2c (wireless) version, Eufy Cam 2, and a 2k Indoor Cam Pan and Tilt. I have been testing most cameras on the highest sensitivity Pros: 1. Won’t drain your wifi: We have relatively low bandwidth, a decent amount of smart devices, and Eufy works well most of the time! The range is good too I have one camera in the backyard away from the house and it streams well. 2. Local recording: Peace of mind knowing someone at the company or something isn’t watching you.. I hope, haha. 3. Installation and setup: Don’t know how it could be easier. 4. Interface is easy to use and setup to customize 5. Battery on dedicated Cameras - The version 2 camera really did last 6 months before I had to charge it, and I had high sensitivity most of the time. The 2C cameras are good, but not quite as advertised. The doorbell is the worst and I have to charge is about every 2-3 weeks. Cons: 1.) Motion detection - this is my biggest issue with the system as its part of most of the products use this hardware to trigger alerts or record. - Detection/reach is NOT 30 feet. I’ve measured on multiple cameras and it rarely picks up anything that far away. Usually starts recording at about 10-15 feet (so half?!). Not great. - People and dogs? Nope. It will often go off with cars, leafs blowing by, when a cloud moves and the suns sines through brighter than the second before, and more. This can be very frustrating, especially when you have it set to “human only” mode. WHAT HUMAN CAN MOVE 35 mph and is 12 feet long? Or what human is 3 inches big and brown…i.e a leaf? Haha. - Slow: If someone hurries up to your door or by the camera, it won’t pick it up. I get a lot of recording of back of heads as UPS folks are going away. -Sometimes misses obvious ones: A family member will walk by a camera 10 ft away in the middle of the day, or go to their car and nothing will have been triggered. Kinda scary. This is especially odd since I’ll get 3 triggers a day from a gust of wind, but not a person walking by… I don’t get it. 2.) False Alarms. This is mostly a product of the motion detection and mentioned above. The scariest in when you have the alarm set to “away” in the middle of the night. The heater turns on in the basement and a “motion detection” alarm goes off. You spring out of your bed… oh crap, someone is in the basement?? Grab a gun, wife runs to grab kids… your adrenaline is running high at 2am and… nothing (thankfully). Have that happen a few times with a camera, or motion sensor and then it becomes a boy who cried wolf situation. Scary when you actually need to be alarmed though you’ve built up a tolerance. But hey, now I’m getting good at “sweeping” an area much like a SWAT team I see in the movies? Haha 3.) Default evening motion detection is set to “all things”. So if cars go by, you’ll have to turn off notifications or else you’ll get a LOT, all night. 4.) Doorbell Battery life: if you want to monitor well, it dies quickly. Again, it picks things up late in my experience so I have to have it on high sensitivity or it misses obvious things. And yes, I’ve tried placing it in different spots. 5.) Image quality not as advertised- for “2k” on some of these cameras, it’s not like the advertisements where you can zoom in and clearly see a license plate or something haha. Faces are pretty good, but it’s not thaaaat great. Better than others for sure, but still not what you’d expect for what seems to be the highest def in the consumer wireless market. 6) Incomplete Security items: These are bonuses, but a fire-alarm, flood sensors, or other items that would make it complete. This includes monitoring service. Would be great to have IF you go away on vacation for a week. I’d pay for it. Lastly, I love that a certain competitor has a cell signal incase wifi goes out. 7) Indoor cam has its own security settings. Why is this separate? Just treat as another 2c, or version 2 camera. Conclusion: I had high hopes for this system. Other systems seems to be less compatible with google home, or charge money to use the cloud, or don’t locally record, etc…. It seems there is not a perfect complete system. This one is pretty good If I were to do it again I would just use the doorbell and maybe door/window sensors. I then would get the cameras and motion sensors from a different company and hope I can bridge it all to a google home or something.

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.

Small and Discrete. Hides well and gives excellent coverage

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.

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.
