You still ultimately have the analogue hole here - pull the camera apart, splice your own hardware somewhere between the sensor and the thing that adds the signatures (or in front of the sensor).
Or just straight up point the camera at a computer monitor, without even trying to hide it. Most of the security camera footage online is already uploaded this way.
