I have two of these, replaced some old smashed Arlec sensor lights with these using existing wiring that came with the house.
Motion detection is decent but not the greatest, Stand alone units so no homebase or anything needed, just the app, no extra fees for cloud recording unless you want increased storage.
Flood light portion motion sensor cant be controlled by the app, it uses old school motion sensors, but it is on a decent gimble so you can point the camera / sensor appropriately.
I wouldn't recommend it if you are after a full on security system, as the on board memory only holds a few days of videos, but it has a nice LED floodlight with decent camera so i think they are good value.
It does have human detection if you only want to capture that, but i found it missed a lot of recordings (delivery guys with hats/boxes in front of them were never detected or recorded) motion only detection works alright.
I believe currently it CANNOT be linked to the homebase 3.
Does it have the option for 24-7 recording like the standard eufy outdoor cam?
