How to use IP network video matrix switch for IP CCTV surveillance system video wall?

What is network video matrix?

Network video matrix is a switching control system which can decode any network video stream to any HDMI/VGA/DVI output. In general, an M × N matrix: that it can support M channel network video input and output N-channel images.

Why we need network video matrix?

When we build a big scale IP CCTV surveillance system, for example, the IP cameras quantity is more than 100 pieces, we want to monitor all video at same time, but we don't want to buy many monitors, in addition, we always need to zoom some important camera video to full screen or combine multiple channels video.In traditional CCTV system, we always use analog video matrix switch and video wall controller, the wiring and operate is difficult, the cost is also high.

If we use network video matrix, we can use one device to manage all video, and input any network video to any display, we also can  splicing zoom/merge/roam/overlay; polling and other support, mode management, and convenient mode to call;

What is the network video matrix functions?

Video / audio input: 

can be either an analog signal input, it can also be a digital signal input. Front of the camera can be directly input analog signal can also be DVR, DVS, IP CAMER other digital signal input. Audio and video digital systems are in pairs, then no separate audio function.

Video / Audio output: 

either by an analog signal output on the TV wall, the digital signal can also be output on the TV wall. BNC / VGA dual output. And visual and audio synchronization output, without the need for additional audio module. It supports up to HDMI high-definition digital screen output, the maximum degree to show up to 120 inches or more large-screen display advantages Multiple HD video at the same time.

Local video switching output

Group switching, synchronous switching switch settings and perform program instructions, forward switching backwards; high-speed ball and PTZ remote control, bright light and dark, far focus, near focus, preset settings and other functions. The full realization of all analog matrix switching function, and each manual or automatic switching function to do a lot of optimization, such as mobile video frame measure alarm linkage switching functions.

Split screen function

1/4/9/16 split screen support, support for multiple monitors while multi-split screen. When playing back multi-split screen support, and also supports the historical and real-time video with different windows at

Where we can buy network video matrix?

You can buy network video matrix from local suppliers, but it is a good idea from China's network video matrix manufacturer, for example, Hikvision DS-B21 , Dahua DH-M70, Sysvideo SVM6000 series  , the price is cheaper, but the quality is also very good.
