Review: This is a Eufy kind of home, love this product! - The eufy security smart lock s3 max is a game changer for our home security and entry door lock. It was extremely easy to set up straight out of the box. Came with all the tools and hardware needed. Looks durable, stylish, and versatile. I can use palm vein recognition which I have never heard of before till using eufy. This system is very accurate and uses biometric data to analyze my palm and open/unlock the front door. Super cool and unique. The other option to be unlock is also using a 4 digit pin that you can easily set up or the old school way if using a key. It is wifi enabled so connecting to the app is seamless once you make a user name and profile. Allows for custom configuration to your liking which is a plus. I.e. loitering alert, AI interface and recognition, and other neat features. If you have the eufy hub like I do, makes it even simpler to store videos and seamlessly connect. The camera is 2k and very crisp and clear. It also allows for getting a live preview of who's outside directly on the backside of the lock which is unique without having to open the door. 2 way communication is built in as well. Awesome set up that is very easy to use. Customize the chimes as well with the integrated door bell. Super easy to spot at night as the keypad lights up and so does the door bell light. Night camera activates and records flawlessly at night as well. All in all, I'm a big fan of all eufy products and this seamlessly integrated to my eufy ecosystem. I can also link it with Alexa and Google which is a plus. It's apple home capable but I have not tried since I don't use the apple ecosystem. No issue on the noise level and most definitely well worth the value.
