If you’re working on AV-over-IP deployments today, performance is only part of the picture.

What we’re seeing more often is that the real challenges come down to the network. Not just how much bandwidth is available, but how traffic is managed, how systems are secured, and how everything is designed to work together long term.

The systems that succeed are not just well installed. They are well planned.

This is where focusing on bandwidth, latency, and network design together, with security built in from the start, makes all the difference.

Start with the Network, Not the Endpoints

IOne of the biggest shifts in AV-over-IP is where success is determined.

It is no longer at the endpoint. It is at the network.

That means thinking about:

• How traffic is segmented
• How devices communicate
• Who has access to what

Security and performance are closely tied here. When AV traffic shares a network without proper structure, both reliability and security can be compromised.

This is why early coordination with IT is so important. When the network is designed with AV in mind, systems perform better and issues are easier to avoid.

AV-over-IP Bandwidth Requirements: What You Need to Know

One of the most common questions is also one of the most important: “How much bandwidth is  needed?” It can also be one of the most overlooked.

Bandwidth determines how much AV data your network can reliably transport at a given time.  Proper planning is critical to ensure performance, reliability, and also scalability.

Key factors that impact bandwidth:

• Video resolution (HD vs 4K or higher)
• Compression level (compressed vs near-zero latency)
• Number of simultaneous streams
• Available network and switch capacity

How to estimate your required bandwidth:

• Determine the bandwidth required per stream
• Calculate the maximum number of simultaneous streams
• Plan for peak usage, not just average
• Verify the available network capacity (1gb, 10gb, etc.)

General Rule of Thumb When Estimating Bandwidth

• 1GB Network can be suitable for most compressed 4K solutions
• 10GB is often preferred/recommended for larger AV deployments and allows for multiple streams without congestion.
• The true determination depends on number of endpoints, encoders/decoders, platform being used and other variables that will differ per project

Failing to address bandwidth requirements early can lead to dropped streams, latency, and network congestion.

From a security standpoint, bandwidth planning also supports better traffic control. When networks are not overloaded, it is easier to monitor activity and maintain stable, predictable performance.

AV Network Latency: Causes and How to Fix It

f something feels off in your system, latency is often the reason.

Latency is the delay between when a signal is sent and when it appears on screen. Even a few milliseconds can cause noticeable issues in conferencing or live environments.

Common causes of AV-over-IP latency:

• Encoding and decoding processes
• Network congestion
• Switch performance and configuration

What to check first:

• Is AV traffic prioritized with QoS?
• Is the network overloaded?
• Are switches designed for real-time AV traffic?

Most latency issues come down to network performance, not just the AV equipment.

Latency and security also intersect here. When traffic is not properly prioritized or segmented, AV streams can compete with other applications or be impacted by unnecessary network exposure. A well-managed network reduces both risk and performance issues.

Designing for Secure Signal Distribution

Security is no longer something that gets addressed at the end of a project.

In AV-over-IP environments, it needs to be part of the design from the beginning.

That starts with a few fundamentals:

• Segment AV traffic using VLANs so it is isolated from general data traffic
• Restrict device access to authorized users and administrators
• Remove default credentials and enforce proper authentication
• Keep firmware and software up to date to address vulnerabilities

Without these controls, AV devices can become an easy entry point into the network.

The good news is that many of these steps align directly with performance best practices. A segmented, well-managed network is not just more secure. It is also more stable and easier to troubleshoot.

Multicast, Scalability and Control

As AV-over-IP systems grow, multicast becomes essential for efficient signal distribution.

It allows a single stream to be shared across multiple endpoints without flooding the network with duplicate traffic.

But multicast also requires careful configuration.

If it is not managed properly, it can:

• Increase unnecessary traffic
• Introduce instability
• Create visibility challenges

This is where coordination with IT is critical. Proper configuration ensures multicast traffic is controlled, efficient, and limited to the devices that actually need it.

Like many parts of AV-over-IP, scalability and security go hand in hand. The more systems grow, the more important it becomes to control how traffic is distributed and accessed.

Where AV-over-IP Projects Typically Run Into Issues

Most challenges we see are not caused by the AV equipment itself.

They come from gaps in planning.

Common issues include:

• Underestimating bandwidth requirements
• Lack of network segmentation
• Misconfigured multicast or VLANs
• No clear coordination with IT teams
• Devices deployed with default access settings

These are not complicated problems, but they are easy to overlook when timelines are tight or responsibilities are unclear.

Addressing them early can save significant troubleshooting time later.

A More Practical Approach Moving Forward

Designing AV-over-IP systems today means thinking beyond signal flow.

It means understanding how AV traffic behaves on the network, how it is secured, and how it will scale over time.

The fundamentals are straightforward:

• Plan bandwidth with growth in mind
• Prioritize and manage traffic correctly
• Segment and secure devices from the start
• Work closely with IT throughout the process

When those pieces are in place, systems are easier to deploy, easier to support, and more reliable for the end user.
