HDCVI DAC Technology

Overview

HDCVI technology is the first on the HD-over-Coax market to realize audio transmission over coaxial cable. Audio information can bring supplementary evidence for video surveillance. In order to provide users with a lossless and real-time auditory experience and a high-quality video & audio surveillance solution, HDCVI brings the advanced DAC (Digital Audio-over-Coax) technology to the HD-over-Coax industry.

Key Features

• Audio-over-Coax

DAC technology is able to transmit audio and video over the same coaxial cable, which greatly simplifies installations and saves labor and maintenance costs.

• Digital Audio Signal Transmission

The digital signal transmission technology converts analog audio signal collected from a sound pick-up or a built-mic into a digital audio signal with low level of noise and distortion.

• High-Quality Audio

With the lossless and real-time digital audio signal transmission, DAC technology can better restore the audio of the monitored site with lower noise.

• Better System Deployment

All HDCVI XVR models support audio-over-coax. Users only need to change a camera to directly upgrade from non-audio to audio solution, significantly protecting users’ investment.

Application Scenarios

Settle Arguments – Checkout Counter and Reception

Pain Points:

Traditional video surveillance offers no audio information. Users can only rely on video monitoring to restore the scene of incident.

Solution:

When there’s an argument in shops or other business establishments, the HDCVI DAC technology can offer audio evidence from the video monitoring system to effectively resolve disputes.

Identify Abnormal Behaviors – Bank and School
