Installation and Setup

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 63 to configure audio options.

Connecting Alarms

WARNING!

Do not exceed the maximum rating of 12 VDC, 0.5 A on alarm

 

output connections.

 

 

Your HD3MDIH/X 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 HD3MDIH/X camera triggers an alarm only when the normal alarm state (open or closed) changes.
