have built in solar so you can put them anywhere without running power or needing to pull them down to recharge batteries. They review really well for the app, picture quality, etc.

Eufy did have an issue a couple of years ago. They are owned by Anker - a Chinese company - and some people discovered an exploit that meant it was possible for data and images to be retained on their servers that China had access to (or something like that - I could be missing some details). They issued a public apology and made changes to correct it.
