Video Wall Solution

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

Signal Chain

Ingest, encode, switch, decode, display

1 · Sources PCs, cameras, conference endpoints
HDMI

→

2 · Encoder node Distributed encoder
connects to the nearest switch

→

3 · IP network Gigabit / 10G switch
VLAN isolation recommended

→

4 · Decoder node Distributed decoder
output to the panel

→

5 · Display LCD wall / LED / projection
windowing, overlay, roaming

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.

High-end 4K60 command centers, monitoring walls	ZY-EH1304 HDMI 4K encoder	1 x HDMI 4K60	IP matrix
KVM operator seats one operator, many machines	ZY-OH1301 4K60 HDMI KVM optical transceiver	Multiview plus KVM	IP network, keyboard follows the picture

Recommended Products

Designed and manufactured in-house · OEM / ODM available · factory direct · 3-year warranty

ZY-OH1301 4K60 HDMI optical transceiver

A 4K30 distributed node with audio embed and de-embed. One model encodes and decodes, so spares stay simple.

Small and mid-size walls

ZY-EH1304 HDMI 4K encoder

4K60 end to end for command centers and monitoring walls where detail matters.

High-end 4K60

ZY-OH1301 4K60 HDMI KVM optical transceiver

Multiview and KVM in one box: one keyboard and mouse across several machines.

Operator seats

ZY-EH1308 8-channel HDMI 4K encoder

An encoder/decoder node for the distributed matrix - add units as the wall grows.

Expansion node

ZY-VW202 2x2 Wall Controller

One HDMI/DVI input to four HDMI outputs with RS232 control; no network required.

Small walls

ZY-DH901 16-Channel Decoder

Sixteen HDMI outputs in a 3U chassis, used as the decoding side of a wall.

Central decoding

Typical Applications

Command centers

Many sources on one wall, switched on demand

Emergency response

Pull signals from other agencies in real time

Monitoring centers

Hundreds of cameras in sequence and on the wall

Conference halls

Main and auxiliary screens working together

Exhibitions and venues

Multi-screen linkage and content distribution

Broadcast monitoring

Many baseband feeds watched centrally

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.
