It’s the same here in Sweden. You’re definitely allowed to vlog and such, if you’re recording yourself, or general environment stuff for a purpose that’s okay. You aren’t allowed to surveil public areas. Naturally this also means that doorbell cameras can be perfectly fine, provided they don’t catch public spaces. If your door points sideways for example, and there’s a hedge blocking any public space, you’re fine.

If you’re in a flat and you’re recording the stairwell, well that’s illegal.
