The AUD-1 audio accessory is an external adapter that connects
directly to the accessory port of compatible Pelco devices. The
AUD-1 is compatible with Spectra
™
camera models that do not have built-in audio.

The AUD-1 audio accessory is designed to work with microphones
that provide a line-level output (+4 dBu). The AUD-1 provides 12 VDC
for microphones that require it, but a preamplifier is required for
microphones that require more power. The AUD-1 encodes audio
from the microphone into a digital G.711 format. The audio can be
streamed with the video to be played back and recorded at the
headend. The AUD-1 can also receive the G.711 digital audio from
the headend and convert it to an analog signal to be played through a
speaker.
The AUD-1 audio accessory can be used in conjunction with the
ALM-1 alarm accessory. If the Pelco device has only one accessory
port, a USB hub is required.
