It's a mess in Europe. It's different everywhere.

In the Netherlands you can record, but only share it with the cops and otherwise you need some clear exception (e.g. dashcam images with minor accidents to your insurer). In all other cases you can either not store them, at least not publicly and all cloud falls under public, or have to inform everyone about their presence on the images, or blurr every identifiable mark (e.g. faces, number plates, names etc). Pretty sure all cloud door cams violate that. So the cops sometimes ask for people's doorcam images, and they are allowed to do that, but likely the people providing them will have recorded it illegally due to it being stored on some cloud account.

This question has already been answered by security footage videos and as long as they are overwritten withing a certain time, stored non publicly and only shared with allowed officials, it's ok.

There are exceptions, but very limited, like clear public good (e.g. whistleblowers).

Yes, it's the same in Denmark. And I unfortunately expect that the law will eventually be relaxed to allow it because it helps law enforcement. We have very little media coverage about the illegality of private people pointing cameras at public spaces, and the most frequent mentions of this is when the police use footage from such cameras to solve a crime. A couple of years ago there was a very high profile kidnapping of a young woman where the footage from a car sentry cam helped the police solve it. They eventually saved the woman and caught the guy who turned out to be a murderer and serial rapist.

Now the cat is out of the bag and it has become an untenable position to be against this type of surveillance. And don't get me wrong, I want rapists and murderers to be caught, but I am at the same time also worried about the effect that this will have down the line, in particular when live AI analysis of footage becomes cheap enough that it gets integrated into these cameras so the cameras can report (what they deem to be) suspicious activity automatically.

Once something illegal is culturally accepted it’s very difficult to remove, it requires a cultural shift.

It’s against the law to post cctv onto things like Facebook in the U.K. but people donor all the time. Early on the law could have banned cloud cameras but it’s too late now, far too many people like to answer front their phones. So glad I no ln get deliver pizzas.

Goods and products must adhere to regulations banning common wrongdoings. Safety standards, health standards, avoiding financial harm, but also privacy. With this I mean, you are absolutely right! Producers and/or sellers of products violating the standards of the society must be pursued! Common people have the convenience not knowing every and all big and small regulations setting the standards of the society when going into a shop buying gadgets or goods. Those active in a specific area must know the specifics of that area and adhere the rules. Should people be aware of radio emission standards when purchasing things working with electricity and validate themselves if the specific product will adere to those when used? Absolutely no! No chance of that. We, consumers, do not need to be aware and able to tell if some food from the grocery will harm people eating it but those should not be sold or produced in the first place. Same with other products in common - product related usual - situations, other rules, other aspects (here, privacy). Producers must know and avoid specific wrongdoings for the common use scenarios of that specific product.

> and I assume in much of Europe

No. In Poland it's legal to record everything, only when you publish the recordings you need the recorded people to agree.

The core issue is that "nothing to hide nothing to fear" argument is correct as long as the government is trustworthy. Not only that, but mass-surveilance greatly improves life because it allows much better crowd management. Case in point - speed cameras. Would you support the removal of all speed cameras in Norway?
