If you have 4 cameras and 3 monitors, you want to see 4 pictures on each monitor. Then you have to connect the video signals of the four cameras to the four input interfaces of the 4K HD Quad Screen Multiviewer, and then output them from one output interface of the 4K HD Quad Screen Multiviewer; the video signals output by the 4K HD Quad Screen Multiviewer are then connected to On the input interface of the 1 to 3 video multiviewer, 3 video signals are distributed through the 1 to 3 video multiviewer, which can be displayed by connecting to 3 monitors respectively.

With the increasing demand for environmental safety, the video surveillance system, as an effective means of security prevention, has attracted more and more attention from all walks of life. It has intuitive visual, large amount of information, flexible control, strict and timely security protection, etc. Advantages, it is widely used in on-site industrial control monitoring, bank security monitoring, shopping mall monitoring and other places. And 4K HD Quad Screen Multiviewer is widely used in video surveillance systems

In a video surveillance system composed of multiple cameras, if each camera occupies a monitor screen display, it will greatly increase the system cost. In order to enable the monitoring personnel to see the situation of all monitoring points at the same time, that is, one monitor The screen can display multiple camera signals at the same time, you need to use a 4K HD Quad Screen Multiviewer. The 4K HD Quad Screen Multiviewer can combine multiple video signals into one output, and display multiple video images on one screen at the same time. It is the core part of the video surveillance system. If you use a 4K HD Quad Screen Multiviewer, you can display the images of four cameras on one monitor at the same time, which reduces the system cost and improves the monitoring efficiency.

The number of cameras in the video surveillance system of large buildings is as many as hundreds, but the number of monitors is limited by the area of the computer room to be much smaller than the number of cameras. Moreover, too many monitors are not conducive to the overall inspection of the staff on duty. In order to achieve panoramic surveillance, that is, to allow all camera signals to be displayed on the monitor screen, a 4K HD Quad Screen Multiviewer is required.
