During a recording, the left and right audio channels are recorded separately. The L & R
audio channels will be saved to the AVI files as follows:
•

If the DVM is configured to always mute (not record) event audio, the audio cannot be
un-muted. The ability to record (or not record) pre-event audio is exclusively controlled
by the DVM configuration.
