So you film the ground?
This complaint is about a different law (§ 8 TDDDG), that explicitly forbids selling and owning devices that are designed as every-day objects and that can record sound and/or video and that.
It's specifically about bug-like devices which transmit the recording. A typical consumer camera does not provide simultaneous uploading, I think. A device that is just recording for storage is not regulated this way.
The law has been applied to baby monitors disguised as toys, which makes some sense to me. Smart watches and phones where the microphone can be controlled remotely, with that capability being marketed specifically for monitoring purposes, have also been targeted.
I think most cameras these days include the ability to live stream?
