AV over IP: What It Is and Whether Your Office Needs It

AV over IP in the office has been a topic for a decade, but it’s now a practical reality for IT managers modernising meeting rooms and collaborative spaces at scale. This guide explains what it actually means, where it adds real value, and the network implications your IT team needs to understand before saying yes to an AVoIP proposal.

Quick verdict

AV over IP is the right architecture for large-scale deployments (10+ display endpoints, large campuses, broadcast environments). For a standard small-to-medium office with normal meeting rooms, a traditional point-to-point HDMI/HDBaseT setup is simpler, cheaper, and easier to support. The inflection point is typically around 10–15 AV endpoints.

Who this is for

IT managers and AV managers evaluating infrastructure choices for office buildouts, expansions, or meeting room technology refreshes.

What AV over IP actually means

Traditional AV distribution uses dedicated point-to-point cabling: one HDMI cable from a source (laptop, PC) to a destination (display, projector). If you want to send the same source to multiple displays, you use a splitter. If you want any source to reach any display, you use a matrix switcher, a dedicated hardware box that creates every possible routing combination.

AV over IP replaces this dedicated cabling with the existing data network. AV signals (video, audio, control) are encoded, packetised, and transmitted over standard Ethernet using existing switches and cabling. A software-defined controller handles routing, changing a room configuration is a software operation, not a hardware re-patch.

The practical implications:

• Any-to-any routing, any source can be routed to any display without a physical matrix switcher
• Infinite scalability, adding a new display or source is adding a device to the network, not buying a bigger switch
• Centralised management, AV routing is managed from a software dashboard, often with APIs for automation
• Single cable type, Cat6a or fibre to every endpoint instead of HDMI + control + audio runs

The main AVoIP standards and protocols

For corporate office use (meeting rooms, digital signage distribution), H.264/H.265-based AVoIP encoders and an IPTV-style distribution model is the most common approach. SDVoE and NDI are primarily for broadcast and production environments.

Network requirements: the part most proposals skip over

This is where many AVoIP deployments run into trouble. The promises in the sales pitch assume a network configured for AV traffic. Reality:

VLAN and QoS are non-negotiable

AVoIP traffic must be separated onto a dedicated VLAN and given QoS priority. Running AV multicast on your general corporate network without isolation will cause packet storms and disrupt normal operations. This requires switch configuration that AV vendors don’t always flag upfront, make sure your network team is involved before any AVoIP procurement.

Multicast considerations

Most AVoIP distribution uses IP multicast, which is efficient for one-to-many (one source, many displays) but requires IGMP snooping properly configured on your switches. Most enterprise switches (Cisco, Aruba, Juniper) handle this fine. Consumer-grade or unmanaged switches do not, you’ll need managed switches at every layer.

Bandwidth

Uncompressed 4K AVoIP (SDVoE) requires approximately 10Gbps per stream. This is not compatible with standard 1GbE infrastructure. Compressed H.265 4K requires 20–100Mbps per stream, manageable on 1GbE with a dedicated VLAN. For 1080p content, bandwidth requirements are substantially lower (~5–20Mbps per stream).

When AVoIP makes sense in a corporate office

• Large conference rooms and auditoriums, where you need flexible routing (laptop, PC, video conference, presentation PC all going to multiple displays)
• Digital signage distribution at scale, 20+ screens across multiple floors or buildings, centrally managed
• Collaborative spaces and war rooms, where any device should be able to share to any display without physical re-cabling
• IPTV/corporate TV distribution, distributing live TV, news feeds, or broadcast content across an office
• Campuses and multi-building sites, where fibre already connects buildings and you want to eliminate point-to-point AV runs between them

When AVoIP is overkill

• Standard meeting rooms (1 display, 1–2 inputs), HDMI and a wireless presentation system (Barco ClickShare, Mersive Solstice) is simpler and cheaper
• Small offices (<10 display endpoints), the management overhead and network configuration cost exceeds the flexibility benefit
• Organisations without managed network infrastructure, AVoIP requires IT involvement; if your switches aren’t managed, it won’t work properly

Key vendors to evaluate

The main corporate AVoIP vendors are Crestron (NVX), Extron (NAV), Visionary Solutions, and ZeeVee. Crestron and Extron are the dominant players in corporate environments and integrate well with room control systems. ZeeVee targets cost-conscious deployments and digital signage distribution specifically.

When evaluating vendors, ask specifically about: multicast configuration requirements, network team onboarding documentation, and what managed switch firmware versions are certified. These questions separate vendors who’ve done real enterprise deployments from those whose reference sites are all greenfield.

Bottom line

AV over IP is a genuine architectural improvement over traditional point-to-point AV for large, complex deployments. For a standard corporate office with normal meeting rooms, it’s typically not the right call, the network complexity and cost don’t justify the flexibility gains. If you’re building out a large conference centre, a multi-screen lobby, or a broadcast/production environment, it’s worth serious consideration. Just make sure your network team is in the room before the AV vendor writes the spec.
