Connecting Audio
Your network camera supports bi-directional audio. There are two supported voice band
channels that function in full duplex mode. Your 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 2-6 ). Your camera can also receive audio from
the client (PC) and provide an industry standard line level output suitable to connect to
audio devices. Audio input and output have 600 Ohm impedance. See
Audio Settings on
page 89 to configure audio options.
Connecting Alarms
WARNING! Do not exceed the maximum rating of 12 V DC, 0.5 A on alarm
output connections.
Your HD3 series 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, your HD3 series camera triggers an alarm only when the
normal alarm state (open or closed) changes.
The network camera has a D/N Control setting which allows control of the moving IR cut
filter when there is a change in state from Normally Open to Normally Closed or from
Normally Closed to Normally Open for Alarm input (see
Alarm Interlock Day/Night Switching
on page 88 for more information). In this way, the moving IR cut filter and the day/night
operation of the camera can be interlocked with external lighting changes using a common
controller such as a photocell or timer.
Figure 2-4 Normal Alarm States
See Alarm Settings on page 88 to configure the alarm inputs.
Connect external devices such as sirens or flashing lights to the alarm output connector to
signal an activated alarm to camera users.
