1 Summary
1.1 System Overview
This video wall central control solution takes mainly economy and stability into
consideration and adopts the most stable B/S structure. Client may directly access server
end via WEB and. Within the LAN, user may operate the server via different client ends
without influences of PC. It eliminates control software problems due to PC breakdown.
The system can integrate video matrix/RGB matrix and other devices which accomplish
management and control of video wall splicing system. User also can connect to video
wall from iPad or any portable wireless terminal. The solution supports wired and wireless
access to video wall application.
1.2 Idea of Design
Economic: low cost, durability, low maintenance lost.
Stable: embedded structure, free from external environments effect.
Display Effect: High resolution, multi-layers, bright color.
Recognition: Splicing Video Wall has been adopted in many fields with high
recognition and easy operation.
Environment-friendly: low power consumption, durability, zero harmful ingredients,
full metal surface, zero radiation.
Reliability: authenticated by various professional tests and internal examinations; the
system is designed to promote compatibility and redundancy function.
1.3 Hardware
According to development need of xxxx control monitor center and to accomplish central
control, we recommend the 2x2 video splicing wall---DHL460UTS-E. It well fulfills the

2 System Function
2.1 Function Overview
The video wall is capable in functions of single screen, partial full screen, full screen
splicing of analog video, computer signal. See Figure 2- 1.
Figure 2- 1
Core of control adopts embedded device, which is stable and safe, effectively
eliminate problems such as virus and crash of windows system within operation of
video wall.
During construction, you just need one network cable to display the HD network video
stream signal on the video wall. It is free of the complicated cable layout, and the
signal quality decreasing resulting from the repeated decoding. . Detailed steps as
the following:
IP speed dome, network camera and other encode signal are sent into display unit
via switch, processed by HD decode module embedded in display unit, is able to
display 1-16 split scene, supporting any tour monitoring. See Figure 2- 2.
Figure 2- 2
When the video wall is connected, it supports multi-operators of video wall at the
same time. See Figure 2- 3.
