The Application System ,which adoptted HIKVISION video&audio server , furnish extensive matrix switching function based on IP. The frame design of whole system is just as follows.

Note: One HIKVISION video&audio server or two in bank will enter network through one Ethernet switchboard,there are too limited space,it doesn??t be described.

In this system ,the host in monitor center can synchronously monitor 16 long-distance scenes ,and can automatically switch to the other 16 after N seconds (user can set the size of N), and can circularly monitor all long-distance scenes according to the setted sequence. Users can randomly take several long-distance scenes to monitor. It realizes the matrix switching function.

Compared with the traditional matrix switching, the extensive matrix switching system based on IP have some unexampled advantages.

At first , in this system ,one host in monitor center can monitor hundreds of long-distance scenes .As a result of withouting matrix switching equipment , it can save cost and improve the flexibility of extending scale at the same time.

Secondly, as a result of adopting IP as audio&video transmission carrier ,compared with the traditional matrix switching , its relay time will be no limits, and it can span over different transmission medium network flat.

Digital-Centralization Surveillance Solution

How to centralizing management the scattered Surveillance centers

An IP Matrix application example

In a massive company and constitution, the surveillance points and centers may be scattered in all over the country or even the world. In the headquarter, as to the different managers for their corresponding management demand, are eagerly to know the picture on spot of every branches on time, especially when some abnormal event occur, they want to know the fact at the first time so that they can surveillance or participate the event handling there.

Fig. 1 to realize the centralizing management to the scattered surveillance centers through "Management Mode"

Fig. 1 is the general description of such system. As to N scattered surveillance centers, it need to add a Management Mode to each surveillance center. By using the network function of "DVRDVS", transfer the "abnormal event" message (alarm) to the network control in the headquarter (desk) through network (special network or public network). By this way, the managers in headquarter can view the pictures and hear the voice of the spot on line through network control.

The management mode should have the following functions:

Actively upload alarm message;
Transfer this alarm message (alarm indication voice, alarm picture and voice on spot) intelligently to the appointed multi-destinations (as in network control)

When the transmission network is the public network, the cost of dynamic IP is low; it is common and become more and more popular to use dynamic IP in ADSL to connect in. In this case, PPPoE protocol should be supported by DVRDVS (actually the picture got from the network control is the result through the connection with DVRDVS launched by it, however it is transparent as to operator). If it is not use the manner as applying for domain name, dynamic IP analysis function need to be added in Management Mode.

When abnormal event occur, it may happened that many network control viewing the same event spot at the same time. It may cause the bandwidth source not enough. We can add a stream media service function in Management Mode to solve this problem by using the stream media service mode responding the access request and transferring this channel alarm picture.

Tag:

DS-8000H Embedded Net DVR and DS-6000S Embedded pre-set box developed and produced by Hangzhou Hikvision Digital Technology Co., Ltd support network alarm linkage, support the voice dialogue with surveillance center, voice broadcast, PPPoE broadband dialup connection in, double bitrate, which is suitable for transfer pictures through broadband and can be sure of the recording picture quality (can reach D1 that is 4CIF resolution) at the same time.

SDK can better support the development of every function in "Management Mode" in order to meet the different function demands of the centralizing surveillance solution.
