2.4.1 Audio in/out connections
The camera includes an interface for a mono audio input (from a microphone) and a mono audio output (to a speaker). The audio
output is a low level signal that requires an amplied speaker (see Specications). The conguration of the audio wiring (Aout, Ain)
is shown in the diagram below.
