With some electronics background and experience, a competent person can remove the wired circuit belonging to the microphone of a digital video camera, to mute the audio recording of the digital video camera, where the audio recording can't be stopped from the digital video camera controls.
This process requires a jeweller's screwdriver set and very steady hands. The microphone needs to be located on the outside body surface of the digital video camera, then when the casing of the digital video camera is unscrewed & opened, you can determine where the microphones wiring will terminate from.
You can then follow the microphone wires back to the circuit board that may only require a circuit board wire connector to be removed from the circuit board, to break the microphone circuit.
The benefit of this process if performed carefully, allows the circuit of the microphone to be restored at a later date if needed. The process is definitely not recommended where working on the digital video camera will void any current warranty of a digital video camera.
During a surveillance investigation, it is necessary to have the audio muted on a digital video camera due to privacy and the Listening Devices Act.
