Have added 2 of these to my EUFY Camera security system and they work very well. All EUFY needs to do now is release a stand alone siren and it will be an even better self monitoring security system.

With the problem of not being able to have multiple security schedules set with the cameras and home base, this solved it by being able to have my side gates on a constant alert setting with door sensors.

I'm new to Eufy but really like that I can buy individual components such as this one, to add to the Eufy camera security system. I investigated several systems but Eufy came highly recommended, is easy to install, good value for money, and I can tailor it to my home. If I decide I need more, it's not difficult or expensive to get more sensors. Tip for beginners: Make sure you have the magnet on the right way round or it'll say your door is open when it's actually shut and you won't be able to set your alarm in away mode.

Also has great app. I have tried other brands before but Eufy has the easiest and most convenient set up and you won't need paid subscription to get all the function.

Third sensor not delivered yet. Electrician cannot finish installing until the third sensor arrives.
