Chapter 1 Product Features

1.1. Introducing System Features


The DVR4000 Client side has the same style as the DVR4000 Server side, easy to use and functionally powerful (complicated configurations have been fully encapsulated and all functional interfaces have been provided so that not only the expansion capacity is ensured but also your time is saved from reading technical documents),. It supports the ability to view at remote side, address book, and reconnection in case of disconnection; incorporates state-of-the-art compression algorithm and technology to ensure the absolute stability of the system; Its hardware and operating system occupies much fewer resources than like products; the image frame is fluent and high definition; and it supports switching of 1-16 channels.

1.2. Network Architecture


The entire network architecture comprises DVR4000 Server's host computer and DVR4000 Client side, and supports UDP and TCP (as shown in the figure).



  1. DVR4000 Server's Host Computer

The DVR4000 Server's host computer is the data source of the whole network system, directly providing audio/video signals for the DVR4000 Client side. Generally, it is a host computer furnished with audio/video compression card, and of the ability to properly run this system's DVR4000 Server software. Each channel of the host computer allows simultaneous connection of multi DVR4000 Clients.
2. DVR4000 Client Side

It refers to the DVR4000 Client side directly connected to the DVR4000 Server's host computer. Any DVR4000 Client can be used simultaneously as the DVR4000 Server of other DVR4000 Client sides, providing audio/video signals for other DVR4000 Client sides. Each channel of each DVR4000 Client side can simultaneously connect to the DVR4000 Server.

For an in-house network which may be local area network or wide area network, the entire network can only be linked to the DVR4000 Server's host computer through a leased broadband, and DVR4000 Client-side host computers B, C and D are linked to DVR4000 Client-side host computer A with DVR4000 Client-side software system. Note: At present, each channel of DVR4000 Client-side host computer can theoretically connect multi - DVR4000 Client sides, however practically, the load amount depends heavily on the actual capability of your computer.

(1) For local area network users, if remote sub-control host computer is of preferable capability, it is then available to transmit video/audio signals through network in such a manner that the video quality is synchronal.

(2) For a wide area network user, it depends on the uplink bandwidth of the network to which the host computer of supervisory control system links. Under limited band width and lower requirements for real-time responsibility and audio/video specifications.
