Audio
In an analog system, separate audio and video cables must be installed from endpoint to endpoint. In a
network video system, a network camera with audio support processes the audio and sends both the
audio and video over the same network cable for monitoring and recording.
Many network camera manufacturers are recognizing the importance of audio, and audio is becoming a
common feature in network cameras. Some video encoders also have built-in support for audio, which
means that they can provide audio functionality in an analog camera installation.
Having audio as an integrated part of the DETEXI NVR is an invaluable addition to a system’s ability to
detect and interpret events and emergency situations. The NVR supports three basic modes of audio
communication: simplex, half duplex and full duplex — depending on the application, it can be configured
to send audio in only one direction or both directions, which can be done either simultaneously or in one
direction at a time.
