Eufy T89000D4 Entry Sensor

These sensors are small, reliable, easy to set up, and look nice and modern. Just put the battery in, spend 30 seconds pairing with the Homebase and assigning it a name, then stick the two parts on your door/window and frame. It's a nice way to supplement a couple of Eufy cams since the cams' motion/human detection is maybe 90% reliable.Be sure to use the Eufy app to customize when you want to receive notifications and alarms. I have mine set so they don't send any notifications when our system is in Home mode, but will alarm when in Away mode. If you have a lot of sensors or modes, it's annoying to configure the settings one-by-one in the app, but you'll probably only do that once or twice anyway.The adhesive backing is very strong, so make sure of where you ... MoreThese sensors are small, reliable, easy to set up, and look nice and modern.

I'm sure they'll pull up the paint when I want to remove them, so if you're worried about that, maybe attach them to Command strips first. (Just remember that if the adhesive is too weak and they fall down, your alarm might go off.)I haven't owned them long enough to comment on battery life, but the rest of the process is incredibly straightforward, and I think these are a good deal when they're on sale.

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 .

Better than recharging every month.

After having cameras (Arlo) which alerted me to stray cats, pigeons flying, shadows moving on the driveway, I am incredibly impressed by these cameras. I am 70+ years old and, frankly needed help in getting the motion part set up. I called Eufy and spoke to a Lou who patiently helped me every step of the way. I went from 40-50 alerts a day with the Arlo to about 5-10 with the Eufy. They truly do pick up only human shapes. And they respond faster than my former cameras. I no longer wake up at night, hearing alerts and worrying about what could be outside. I love these cameras.
