Hello Yes, it works worldwide. The description is a bit daft. I bought it. Highly recommended. Can view the whole flat worldwide. However, it is difficult to drive over thresholds. 1cm is already too much, so I installed wheelchair ramps in the flat 😆 The app is also available for iPhone. Just search for Rola Smart Robot (the blue dog paw symbol) PS: You can really annoy your girlfriend with this thing, as you can still speak into it and record 😆😆

Everything was fine, but after a few months I can no longer log in. The camera does not see qr code

Yes. It returns to the upright position.
