1 Product Overview
Introduction 1.1
DH series decoders are network video decoding devices designed and developed for online video
surveillance system. The device has powerful data processing capability and stable network function,
and supports diversified encoding formats. It is easy to extend, easy to maintain, and convenient to
access. This design facilitates installation, deployment, unified control and system management of
the entire online video surveillance system. Meanwhile, it substantially reduces overall system cost.
Main Features 1.2
Decoding
 Decoding capability of the decoder depends on its internal decoding chip.
 Real-time stream decoding
Obtain local real-time bit streams, encode and then output.
 Previous stream decoding
Obtain the local history bit streams, encode and then output.
 Information feedback
Web interface can accurately get current decoding status.
Network
 Support remote control with network.
 Synchronize system time with NTP server.
 After you configure the front-end encoding device information, decoder can automatically
connect the encoding device, and then begin work independently and reliably.
 In forwarding mode, decoder can get the random data stream from the network server
accurately, to realize decoding output.
Output Port
