Installation and Setup
Connecting Audio
Your camera supports bi-directional audio. There are two supported voice band channels
that function in full duplex mode. The camera can transmit audio from the camera to the
client (PC) using any audio source that provides an industry standard line level input (see
the terminal strip as depicted in
Figure 2-7 ). The camera can also receive audio from the
client (PC) and provide an industry standard line level output (3.5 mm stereo or mono jack)
suitable to connect to audio devices. Audio input and output have 600 Ohm impedance.
See
Audio Settings on page 64 to configure audio options.
Connecting Alarms
WARNING! Do not exceed the maximum rating of 12 VDC, 0.5 A on alarm
output connections.
Your camera has one alarm input and one alarm output. Connect mechanical or electrical
switches to the alarm input connection to allow event-triggered recording. When alarm
inputs are configured, the camera triggers an alarm only when the normal alarm state (open
or closed) changes (see
Figure 2-8 ). See Device Settings on page 51 to configure the alarm
inputs.
