AV-over-IP Distribution

Moving AV onto the data network turns a room build into a network build. We quote the encoders, the switching, the PoE budget and the control layer together, so the VLAN and multicast design is settled on paper before anything is racked.

Quoted: Encoders and decoders, switching, PoE, control surfaces, cabling
Boundary: The VLAN, multicast and QoS design belong to the network owner

Overview

The moment AV becomes a network project

Matrix switchers scaled poorly and cabled worse, which is why AV distribution moved onto the data network. What that change actually does is transfer the hard part from the AV rack to the network team: video streams become multicast traffic, endpoints become PoE-powered network devices, latency and jitter become AV quality problems, and a switch misconfiguration becomes a room that does not work. None of that is a reason to avoid AV-over-IP — it is a reason to have the network conversation before the equipment is ordered, which is precisely when it usually does not happen.

Moving parts

What has to be agreed before the order

Bandwidth per stream is the first number, and it varies enormously by codec approach. Lightly compressed, visually lossless streams look superb and consume real bandwidth per endpoint; more heavily compressed approaches fit comfortably on a gigabit access layer at the cost of latency or quality. That choice determines whether the AV traffic sits on the existing access layer or needs its own.

Multicast is the second, and it is where AV-over-IP deployments most often stall. Distributing one source to many endpoints is multicast by nature, which brings IGMP snooping, querier placement and group management into scope. These are ordinary network functions, but they must be deliberately configured, and on a shared network they must be agreed with whoever owns it.

Then power and cabling: endpoints are typically PoE-powered, so the AV rollout lands directly on the closet power budget alongside the cameras and access points already there. And copper category and run length matter more here than in ordinary data use, because sustained high-bitrate streams are less forgiving of a marginal plant.

What we quote

The AV layer and the network under it

Legrand, Crestron, Harman, AtlasIED, Shure, Allied Telesis and Netgear all carry priced rows across these lines.

Encoders, decoders and extension

Networked AV endpoints and the extender estate for the runs that stay point-to-point. Legrand carries deep priced AV infrastructure inventory; quoted with the mounting and cabling each endpoint needs.

Control and processing

Crestron and Harman carry priced control, processing and distribution lines. The control surface is specified from how the room is actually operated rather than from the endpoint vendor's default.

Switching sized for AV traffic

Allied Telesis and Netgear managed switching, quoted with the multicast and PoE requirements written down rather than assumed. Whether AV shares the existing access layer or gets its own is a decision, not a default.

Room audio and microphones

Shure and AtlasIED carry deep priced audio inventory — ceiling arrays, table and wireless microphones, amplification and processing for the rooms where audio is the part people actually complain about.

What to send

Enough to quote without a redesign later

Source and destination count per room or zone, and how many streams run at once
Resolution and frame rate required, and whether latency is critical
Whether AV shares the existing network or gets a dedicated one — and who owns that decision
Closet PoE budget as it stands today, before the AV endpoints are added
Cable plant category and run lengths, especially anything over 90 meters
How rooms are operated: touch panel, button panel, scheduling integration or none

Limits

What stays yours to run

The network design is not ours to own. VLAN structure, IGMP snooping and querier placement, QoS policy, and whether AV shares infrastructure with everything else are decisions made by whoever operates the network — and they must be made before the endpoints arrive, not during commissioning week. We quote the switching that supports the design and will tell you plainly what the equipment requires; we will not configure your production network for you.

We also do not run AV as a managed service. Room commissioning and installation are capability-level work we quote alongside the hardware, but the day-two operation, the room support and the platform relationships stay with your team or your AV integrator.

Questions

AV-over-IP questions

Does AV-over-IP need its own network?

Not necessarily, but it needs a deliberate decision. A shared network can carry it well when multicast, QoS and PoE budgets are properly configured; a dedicated one removes the negotiation with the network owner at the cost of more switching. The failure mode is neither choice — it is deploying onto a shared network nobody was consulted about.

How much bandwidth does each stream use?

It depends heavily on the codec approach, from visually lossless streams that consume real capacity per endpoint to more compressed approaches that fit comfortably on a gigabit access layer. Tell us the resolution, frame rate and latency tolerance and we quote a switching layer sized to that rather than to a marketing figure.

Will the existing closet power the AV endpoints?

That is the question worth asking early, because AV endpoints land on the same PoE budget as the cameras and access points already installed. We total the budget with the AV devices added and tell you which closets need to change before you order the endpoints.

Can you commission the rooms as well as supply them?

Installation and commissioning are quoted alongside the hardware as capability-level work — mounting, cabling, endpoint configuration and room testing. What we do not do is operate AV as a managed service or provide day-two room support; that stays with your team or your AV integrator.
