AV over IP vs HDMI over LAN: What’s the Difference and Which Do You Need?

Both AV over IP and HDMI over LAN push video signals across standard network cabling. They share shelf space in every AV integrator’s toolkit. But they’re not interchangeable, and picking the wrong one costs you money, flexibility, or both. This guide breaks down how each technology works, where it shines, and which MonitorsAnyWhere hardware matches each approach.

AV over IP vs HDMI over LAN: A Side-by-Side Comparison

Feature	AV over IP	HDMI over LAN
Signal type	Compressed or uncompressed video over IP network	Point-to-point HDMI signal over Cat5e/Cat6
Max distance	Unlimited (routed across subnets)	~100 m per segment (Cat6)
Switching	Any-to-any AV over IP matrix via network switches	Dedicated transmitter-receiver pairs
Latency	1–30 ms depending on codec	Sub-1 ms (near zero)
Scalability	Add endpoints by plugging into the network	Each new display needs a dedicated receiver
Best for	Control rooms, multi-building campuses, large video walls	Small video walls, single-room setups, trade shows
Typical resolution	4K@60Hz 4:4:4 (H.265 or JPEG 2000)	4K@30Hz or 1080p@60Hz depending on extender

That table gives you the quick version. Now let’s get into when each technology actually makes sense on the ground.

When AV over IP Is the Right Call

If your deployment spans more than one room, floor, or building, AV over IP is almost always the answer.

Traditional point-to-point HDMI extenders hit a wall at roughly 100 meters over Cat6. AV over IP doesn’t care about distance because it treats your video feed like any other network packet. Route it through existing managed switches, push it across VLANs, send it to a display three buildings away. The network is the matrix.

Control rooms are the textbook use case. A NOC with 16 sources and a 4×4 video wall needs any-to-any switching: any source on any screen, rearranged on the fly. An AV over IP matrix handles that through software, not a rack-mounted hardware matrix that costs five figures. Need to add a source? Plug in another encoder. Done.

Multi-site deployments are another clear win. Think corporate offices with lobbies in five cities, all pulling the same branded content plus local feeds. AV over IP solutions let you manage everything from a single dashboard without dedicated long-haul cabling.

For cable runs over 15 meters where you still want 4K@60Hz at full chroma, H.265 compression keeps bandwidth under 1 Gbps per stream. That’s a fraction of the 18 Gbps an uncompressed HDMI 2.0 signal demands.

When HDMI over LAN Makes More Sense

Not every deployment needs IP-based distribution. If your screens sit within 100 meters of the source and you need rock-bottom latency, HDMI over LAN keeps things simple and affordable.

Zero-client setups are the prime example. You connect a small hardware endpoint to each display via Cat5e, feed it an HDMI signal from a central PC, and the display mirrors the output. No encoding delay, no compression artifacts, no VLAN configuration. Plug and play.

Temporary installations are another sweet spot. Think HDMI over LAN at trade shows where setup time is measured in minutes. Run a single Cat6 cable to each screen, connect your source, and you’re live. No managed switches, no IT department on speed dial.

Single-room video walls (a 2×2 or 3×3 behind a reception desk, for instance) also favor this approach. Short distances, low source count, sub-millisecond latency for perfectly synchronized content across all panels.

MAWi Spacewall: Built for AV over IP Deployments

MonitorsAnyWhere’s MAWi Spacewall AV-over-IP solution is an Android-based platform designed specifically for video walls and digital signage at scale.

Each Spacewall unit acts as both encoder and decoder, so any device in the network can send or receive. That’s the “any-to-any” flexibility control rooms and multi-zone installations demand. It runs on standard gigabit Ethernet. No proprietary switches required.

What makes it practical: Spacewall supports content scheduling, remote management, and source switching from a centralized interface. For a 20-screen corporate campus, one admin manages content across every lobby, meeting room, and cafeteria display without leaving their desk. The Android backbone also means you can run local apps on each endpoint when needed, a significant edge over dumb encoder/decoder pairs that only pass through video.

MAWi Zero: Purpose-Built HDMI over LAN Hardware

On the opposite end, MAWi Zero HDMI over LAN is a zero-client device that does exactly one thing well: it takes an HDMI signal from a host PC and delivers it to a remote display over a LAN cable.

No operating system. No fan. No moving parts. Power draw sits around 5 watts per unit. For a 3×3 video wall running nine 55-inch panels in a retail environment, that’s 45 watts total for the client hardware. Compare that to nine dedicated media players pulling 30–65 watts each.

MAWi Zero supports distances up to 100 meters per run on Cat5e. Connect it to the display’s HDMI input, run the Ethernet cable back to a host PC, and the screen mirrors whatever the PC outputs. Screen grouping, video wall layouts, and content assignment all happen from the MAWi server software.

Fewer network dependencies, faster setup, lower per-endpoint cost. That’s the trade-off.

Real-World Example: Power BI Dashboards on TV Screens via AV over IP

Here’s where AV over IP solutions prove their value beyond basic content playback.

A logistics company runs Power BI dashboards tracking warehouse throughput, delivery SLAs, and fleet utilization across six 65-inch screens on two warehouse floors plus one executive office upstairs. With AV over IP, a single source PC runs Power BI in a browser, and the Spacewall network encodes and routes that feed to all six displays. Each screen can show a different dashboard, switched remotely. When the CFO wants real-time KPIs in the boardroom for a quarterly review, IT reassigns one stream in about 30 seconds. No cables moved, no PCs relocated.

Try doing that with point-to-point HDMI extenders across two floors. You’d need six separate cable runs, possibly signal boosters for anything past 50 meters, and zero flexibility to reroute sources on the fly.

Before committing to either approach, it’s worth stepping back to compare total cost across hardware, licensing, and installation. The per-endpoint price is only part of the picture.

FAQs about AV over IP vs HDMI over LAN

What is the main difference between AV over IP and HDMI over LAN?

AV over IP encodes video and sends it as network packets across standard IP infrastructure, allowing any-to-any routing and virtually unlimited distance. HDMI over LAN extends a raw HDMI signal point-to-point over Ethernet cable, typically limited to 100 meters, with sub-millisecond latency.

Can AV over IP run on my existing network switches?

Yes, in most cases. AV over IP runs on standard managed gigabit switches. Configure a dedicated VLAN for video traffic to prevent bandwidth contention, and enable IGMP snooping to keep multicast streams from flooding ports.

Is HDMI over LAN good enough for 4K video walls?

It depends on the extender. Many HDMI over LAN devices support 4K@30Hz over Cat5e or 1080p@60Hz. For full 4K@60Hz at 4:4:4 chroma, you’ll likely need AV over IP with H.265 compression or a premium Cat6a extender.

How many screens can MAWi Spacewall support in a single deployment?

Spacewall scales with your network. You add screens by adding endpoints to standard Ethernet. Deployments of 50+ screens across multiple locations are common without specialized hardware beyond managed switches.

Does MAWi Zero require a separate PC at each display?

No. A single host PC drives multiple MAWi Zero endpoints over LAN cables. One machine can power an entire video wall, which cuts hardware costs and simplifies ongoing maintenance.

Which option is better for temporary event installations?

HDMI over LAN. MAWi Zero endpoints need no IP addressing and no software setup at the display side. Plug in the LAN cable, connect HDMI to the screen, and content appears. Setup for a 4-screen booth takes under 15 minutes.

Not Sure Which Fits Your Setup?
