What is a Distributed Visual Control System?
The distributed visual control system is dominated by command technology and information technology, and makes full use of advanced technologies such as modern communication technology, network technology, automation technology, and electronic monitoring, and builds a modern, networked, and intelligent processing platform with data transmission network as the link, computer information system as the support, and integrates audio processing, video splicing processing, network transmission, environmental monitoring, visual control and other functions.

The distributed system can easily connect the audio and video collection, transmission, control and display of the command center through the digital network for centralized management and control. And it has great flexibility and scalability, supporting multi-point sharing of audio and video signals, preview control of mobile terminals, and interactive communication of audio and video networks.
Compared with the traditional centralized audio and video integration system, the Geffen GEFFEN distributed visual control system has the following advantages:
1. Ordinary super 5 and 6 network cables or optical fiber connection wiring are used to greatly reduce the type and amount of wiring in the project.
2. There is no need for complex networking equipment such as servers, and only one switch can complete the installation and networking of the whole system.
3. Adopt distributed architecture design, each node operates independently, and can increase or decrease nodes arbitrarily according to the on-site conditions.
4. It integrates the functions of matrix, transmission, splicing, segmentation, central control and other equipment, which greatly reduces the cost of engineering equipment and maintenance.
5. All audio and video signal sources and large-screen output images are all visualized, and the control is more accurate, and can be controlled in real time through computers, mobile phones and tablets.
The GEFFEN distributed visual control system enables the following functions:
1. It can realize seamless switching, windowing, zooming, spanning, roaming, and superimposed display of all signal sources on any display terminal, and the splicing mode can be customized.
2. WYSIWYG visual touch operation can be carried out on all audio and video, surrounding environment, etc. through PC, tablet, touch all-in-one machine and other terminals.
3. By collaborating with the environmental control host, it can realize efficient and convenient environmental control and management functions, and can remotely manage lights, curtains, volume, power supply, etc.
4. Signals from different locations can be interconnected, and nodes can be added arbitrarily to expand the scope of interconnection and realize multi-regional distributed centralized management.
5. The interface can be designed arbitrarily through customization to realize functions such as visual operation, signal preview echo, and system settings.
At present, the GEFFEN distributed visual control system has gradually replaced the traditional audio and video integration system, and is widely used in command center, dispatch center, monitoring center, multimedia conference and other fields.


GEFFEN is specialized in processinghigh definition video signals for years. wehave developed and produced a series ofpro video devices, including signalconverter, multi-viewer, optical fiberconverter, signal distribution amplifiersignal generator and matrix switcher, etc.
