When distributing video throughout a space, there are two main approaches. The first is a conventional matrix switcher, a central device that routes sources to displays. The second is AV over IP, where video and audio are distributed over the corporate data network. Both work. The difference is the scale and expected growth at which each approach makes sense.
A simple rule of thumb is this: for one or two rooms with a few displays and no planned expansion, a matrix switcher is simpler and less expensive. When the number of displays is expected to grow, signals need to travel across an entire building, each display needs to show independent content and the whole system should be managed from one location, AV over IP becomes the better choice.
Below is a concise explanation of what you are choosing between, a comparison across the key criteria and a simple rule to guide the decision.
What you are actually deciding between
A matrix switcher is a central device with a fixed number of inputs and outputs. Every source and every display has its own connection, and the matrix routes signals between them. It is a proven and straightforward approach that works well for small, stable installations.
AV over IP sends video and audio over the same type of network infrastructure a company uses for data. Each display and each source connects to the network as an independent device with its own address. This allows the system to grow and reach much greater distances, although it requires a properly designed network.
Both approaches can deliver high-quality video. The real difference is how the system behaves when it grows and expands.
Comparison across the key criteria
| What we are comparing | Matrix switcher | AV over IP |
| Growth and scalability | Fixed number of outputs. Beyond the limit, a larger device is required. | Expands by adding devices to the network, with practically no fixed endpoint limit. |
| Distance | Shorter routes tied to direct cabling. | Across an entire floor or building, and over fibre even across a campus. |
| Display independence | Displays may need to negotiate a common capability level. | Each display has its own stream and maintains its own quality. |
| Behaviour during expansion | Adding a device can reduce quality or result in a display failing to show an image. | Adding an endpoint does not disrupt the rest of the system. The new display operates independently. |
| Management and remote control | Primarily local operation on site. | Control and diagnostics from one location, including remotely. |
| Audio and microphones | Audio is typically tied to the video signal chain. | Video and audio can be routed independently. A microphone can be sent somewhere different from the video. |
| Cost for a small deployment | Lower, with a simpler solution. | Higher overhead and unnecessary for a single simple room. |
| Cost logic at larger scale | A large matrix is expensive and still has a fixed capacity. | With many endpoints, the economics improve because the system expands incrementally. |
| Network requirements | Virtually none. It operates as a separate system. | Requires a correctly designed network. |
The first rows show where a network-based approach has the advantage. The final two highlight where a matrix switcher genuinely wins through simplicity and lower cost in smaller deployments.
When a matrix switcher is enough
A matrix switcher is the right choice more often than the table above might suggest. It is sufficient and less expensive when the following applies:
- One or two rooms with only a few displays.
- Short cable runs within a room or floor.
- A stable installation with no plan to add a significant number of displays.
- You do not need to manage multiple spaces from one location.
In this situation, AV over IP adds unnecessary complexity, while direct routing through a matrix switcher performs the same task more simply.
When AV over IP is the better choice
AV over IP becomes worthwhile when at least one of the following applies:
- You distribute video and audio across multiple rooms or floors.
- You have a video wall or a large number of displays showing different content.
- The number of displays and audio zones is expected to grow.
- Each display needs to show independent content.
- You want to manage and switch the entire building from one location.
- You need distribution across an entire building or campus.
The more of these points apply, the more clearly the decision shifts towards a network-based architecture.
How to decide
If you are still unsure, three questions will point you in the right direction:
- Will the number of displays and audio zones grow? If yes, a matrix switcher will eventually reach its fixed capacity.
- Do you need distribution across the entire building? If yes, direct matrix cabling becomes limiting over longer distances.
- Does every display need to show different content? If yes, independent network streams are an advantage.
If most answers are no, a matrix switcher is sufficient. If most answers are yes, design the distribution as a network. The specific network solution to use depends on the scale and requirements of the AV over IP deployment.
Frequently asked questions
Is AV over IP always better than a matrix switcher? No. For one or two rooms with a few displays and no planned growth, a matrix switcher is simpler and less expensive. AV over IP becomes worthwhile with a larger number of displays, distribution across a building and future expansion.
When is a matrix switcher enough? For a small, stable deployment. One or two rooms, short cable runs, a few displays and no plan for significant expansion. In that case, it is both simpler and less expensive.
Which option is cheaper? For a small deployment, a matrix switcher. With a large number of displays and audio zones, AV over IP can be more economical because it grows by adding endpoints instead of replacing the central device.
Does AV over IP replace a matrix switcher? Yes. The network takes over the task of routing sources to displays. The advantage is that the system does not have a fixed ceiling defined by the number of physical connectors and can grow by adding devices. For small spaces, however, a matrix switcher remains the simpler choice.

If you are deciding between a matrix switcher and a network-based solution for a specific space, the first decision concerns the architecture, before selecting individual devices. A consultation on video distribution architecture will show what the space and its expected future growth actually require.
