2-YEAR BATTERY LIFE: One battery provides monitoring for 730 days.
FOR DOORS AND WINDOWS: Small and compact design fits onto any door or window frame.
100-DECIBEL SIREN: If a forced entry is detected, a siren as loud as a jackhammer will be triggered on HomeBase, and you’ll be notified instantly on your smartphone.
EASY INSTALLATION: Just peel off the mounting tape and stick the sensor onto the door or window you want to monitor.
I bought and installed two of these sensors in January 2021, and haven't thought about them since! I was initially weary that the batteries are not replaceable. However, we open and close our doors at least 10 times a day, and with a promised battery life of 2 years, mine still show full battery and work every time without missing a single opening or closing of the doors after nearly 3 and a half years.

Good Security Sensor
We have many eufy security devices and they work very well. We have chosen to start replacing all of our current window and door security sensors with eufy.

This has good range and the magnet is strong enough to allow an inch and a half of gap. Works well

Great video doorbell
I like to know when a delivery is made on our steps or a visitor is present. We live in a condo and spend a lot of time upstairs. We seldom hear a delivery person drop off a package for us, and it's comforting to know that if a package is delivered that the package is handled properly. And if a package is taken from our steps by someone else, it's nice to have proof that a package was stolen by someone we don't know but can identify to the authorities.

Easy mounting and integration.
You need the Home Base, either one but now get home base 3 as home base 2 will soon be not for sale anymore and all equipment will be transferrable to home base 3.
This sensor can be put on any door or window simply with the included double stick tape. Works on gates, doors, sliding doors, any window, hatch, etc. Integrates with my Google Home app and Eufy app. Can make it beep when opened/closed and trigger an alarm via home base that's approximately 100db loud when alarm is armed. Only downside is the alarm goes off if sensor tripped is closed. Disabling the alarm tone. Wish it stayed going until manually silenced in app by user. Eufy really should update via firmware this glitch. Otherwise, works great, easy to install and sync to home base and Google . Takes 1 AA battery which lasts 2 years they say. Better than recharging every month.
