Unless it has some kind of "allmenn interesse", aka "general interest", where it's better for society that it's published vs your right for privacy. For instance if you're a public figure doing something bad in public and getting video taped, you can't stop that from getting out by not "approving" it.

Dash cam: The footage can not be published with faces and/or license plates legible (anything that can be linked to a person really). You are allowed to keep the footage for private purposes unedited.
I think there is a law regulating where and if such a camera is allowed to be positioned and how you are allowed to process the imagery.
It is also not forbidden to film out of my doorway, is it?
Law is certainly complex in this case.
Storing close-up videos of strangers indefinitely is hopefully forbidden, but not filming a street per se.
It is if you're looking at the public road out of your door. Cameras need to be angled so that they do not film public spaces. There was a case a few years back about police stations in Baden-Württemberg needing to shut down their cameras because one complaint found them to surveil too much of the sidewalk.
Privacy law can become pretty complicated.
Is there an exception for ATMs?
[edit] just to clarify, I said "certainly" because the idea of public space being unsurveilled is such a foreign concept to me these days. I do think there are valid safety use cases for private cameras on the street - cash machines being high on my list. Government cameras (or those accessible by government without a warrant) I think should require a much higher standard to be met. But for private use, for instance, my front door camera covers the area of sidewalk directly in front of my house. Where I live, I am liable for accidents that occur on that piece of sidewalk and the curb, should I not shovel my snow or someone slips on autumn leaves or if a tree limb falls on someone's car. I don't like the idea of the police accessing that camera, but I do like the idea of having a record of what takes place in a public area I'm personally liable for maintaining.
I don't know though.
In Germany, you're also partially liable for accidents that happen due to side-walk maintenance (which is a stupid idea imho because many people just don't care, so you end up with lots of icy sidewalks in winter). But Germany is generally cheap on damages, so if someone falls in front of your house and breaks their wrist and cannot work fully, you'd pay a few thousand Euros at most. Since you'd need to actually prove damages in court, and would need to actually break your bones etc, I haven't heard of scams in that regard. Might happen occasionally, but it's not a common thing.
AFAIK, smart doorbell like Ring have breached UK private laws/GDPR

In public spaces it's probably somewhat regulated, but it might be a small sign.
On private property with video surveillance there also always seems to be some signage, clearly visible.
The purpose of that is for sure also to prevent crime from happening in the first place.

Kinda like a dashcam, but worn by a person rather than a vehicle.
Image rights and rights for privacy are up there just below right to life, so for example in a court case, video evidence is only accepted if it's a murder or attempted murder case. If you film me stealing your stuff it's not admissible.
Main reason being that the constitution considers your right to go about your business in any place with whoever you want to not be disclosed without your consent.
Public cameras must adhear to strict data retention rules and signs must be posted. Additionally in cities like Zürich doing face recognition on public ground is forbidden and will most likely be nationwide soon.
Dashcams are a gray zone. What is for sure is that the footage can not be used in court unless it's a very serious case and you can not publish footage without anonymiezing it. What Tesla does with storing footage in a Dutch DC is probably illegal but so far the authorities have not done anything against it.
Culturally it definitely still works which is arguably the function of the law to begin with.
