Description
Technical field
The present invention relates to field of computer technology, more particularly, to a kind of video monitoring system and method.
Background technology
Video monitoring system composition schematic diagram shown in Figure 1, existing Large Scale Video Monitoring System is recorded by multiple stage hard disk
Camera, monitoring computer, multiple stage Video Decoder, multiple stage IP Camera/machine, the multiple stage network equipment and multiple stage show and set
Standby composition.The operation principle of this system is：Many in the LAN being made up of the network equipment to being connected to using DVR
The video of platform IP Camera/machine collection, realizes multiple image solution by way of a display device is using picture segmentation
Code display.Specifically, when the display device needing more than two carries out large screen display, because DVR at most can connect
The display device quantity connecing is two it is therefore desirable to access Video Decoder to IP Camera/machine output by the network equipment
Video data encoder be decoded and export large-screen image is realized on display device showing；When connecing in a network equipment
When the quantity of the IP Camera/machine entering exceedes the maximum way of DVR, then need to increase the quantity of DVR,
