Video Wall Solution
Distributed architecture: any source to any screen over one cable
4K60 end to end, expand by adding nodes instead of re-cabling
Traditional versus distributed: the word is expansion
One requires new cable runs, the other just needs another node
Four pain points of traditional matrices
- Sources spread across floors or buildings: cabling dominates the budget
- Expansion means new cables and a new frame, with downtime in the machine room
- Once 4K hits the wall, legacy bandwidth and interfaces fall behind
- Operator seats need picture and keyboard-mouse switching from two separate systems
Our approach
- Connect sources where they are : one cable from each node to the switch, no dedicated home runs
- 4K60 end to end : the ZY-EH1304 HDMI 4K encoder encodes and decodes 4K60 in one box
- KVM operator seats : the ZY-OH1301 4K60 HDMI KVM optical transceiver moves keyboard and mouse with the picture
- A low-cost path for small walls : a 2x2 controller that needs no network at all

Distributed nodes do encode, so there is latency. For keyboard-and-mouse sensitive seats choose the KVM model (ZY-EMX2000-S); pure monitoring walls can use standard nodes and cost less.

FAQ
Is there latency with a distributed system?
Yes. Distributed nodes encode, so latency is in the millisecond range and varies with resolution, bitrate and network conditions. For operator seats we use the KVM model. We recommend a bench test with demo units before committing.
How should the network be planned?
Put video on its own VLAN and budget tens of Mbps per 4K stream (H.265), then size the switch for the total plus roughly 30 percent headroom. Confirm actual bitrates on your own equipment.
Can it work alongside an existing matrix?
Yes. Distributed nodes take HDMI in, so a legacy matrix output simply feeds them. You can migrate in stages: move a few sources first, verify stability, then switch the rest.
How many screens can it drive?
In a distributed architecture the limit is network capacity rather than chassis slots, so you expand by adding nodes. We will size it against your source and screen list.
