Here’s a little more background. Yes, the camera will probably work for basic functionality in Europe, but some functions won’t work (eg. Alexa support).
See this topic for more details:
and in particular, this post from a Wyze employee:
A key point in that post: “We tried to get Amazon to limit selling our products to the US but that didn’t happen.”
There is a warranty, but Wyze cannot ship replacement cameras to international addresses.
Wyze may go international at some point, but given all the other development they have going on, I personally wouldn’t expect that to happen for a long time.
