Note that there is a difference between Panoramafreiheit (freedom to record a public building / space with people walking around) versus recording the street before your house with an always-on security camera (almost always forbidden).
Even having a fake camera pointing at a public space can be forbidden as it creates surveilance pressure on people using the space.
