AV-over-IP in Corporate Networks: The End of USB Hell in Meeting Rooms
Reading time: 4 minutes
Executive Summary
Extending USB and HDMI cables across meeting room tables is obsolete. It leads to meeting disruptions and overburdens corporate Helpdesks. The solution lies in transitioning to the AV-over-IP standard. Video, audio, and power (PoE) are transmitted as standard TCP/IP data over conventional corporate twisted-pair cabling (CAT6a) directly into network switches.
IT departments invest significant effort into ensuring the corporate network is optimized, secure, and organized. However, this order often clashes with the reality of modern boardrooms.
In an attempt to connect a complex array of cameras and microphones, installers commonly rely on a multitude of active USB and HDMI extensions and adapters. In worse cases, they attempt to stream 4K video over the corporate Wi-Fi. To an experienced network administrator, this approach is a ticking time bomb.
A tangle of cables and unstable hubs hidden under carpets or tables results in unreliable connections. A simple move of a chair can snag a cable, causing a crucial video call to freeze or drop entirely.
This conflict between audiovisual technology and IT standards has an elegant solution: today’s AV devices can be fully integrated directly into the IT infrastructure.
What is AV-over-IP technology and how exactly does it work?
AV-over-IP (Audio Visual over Internet Protocol) is an architecture that replaces traditional point-to-point cabling and various adapters with a unified standard—structured Ethernet cabling over an existing LAN infrastructure.
The principle is simple: a hardware device (encoder) independently and in real time converts video and audio from cameras or microphones into standard IP packets. A standardized data stream then travels across the corporate network in the same way as an employee sending an email.
What does the setup look like in practice?
The installer no longer needs to run complex bundles of different types of cables.
A single network cable leads to a ceiling microphone or control panel—typically a gigabit CAT6a Ethernet cable (with an RJ-45 connector).
All endpoint devices are connected directly to a central gigabit Layer 2/Layer 3 network switch.
The installer no longer has to run complex bundles of various types of cables.
Why does AV-over-IP immediately reduce the load on your IT Helpdesk?
An architecture based on network-delivered AV signals instantly relieves overburdened IT support teams. It removes the most common causes of daily Helpdesk incidents:
1. Troubleshooting power issues via Power over Ethernet (PoE)
In a traditional setup, technicians had to run a thick 230V power cable to the desk, along with HDMI and separate data cables (Ethernet, USB, etc.). With AVoIP, the Ethernet cable also provides power.
With the Power over Ethernet (PoE) standard, desk controllers and touch displays receive power directly from the network. The durable snap-in RJ-45 connector fails mechanically far less often than fragile USB-C adapters, which can wear out easily.

2. Protecting the corporate network from congestion (VLAN and QoS)
It might seem that a 4K video stream could overload a corporate network. The solution is strict network segmentation.
VLAN (Virtual Local Area Network): The AV installation operates within a strictly isolated network segment. Audio and video traffic are separated from standard corporate data traffic.
QoS (Quality of Service): The network is configured to prioritize video calls over activities such as file downloads, ensuring that video conferencing is not disrupted by lower-priority traffic.

3. Reducing user stress through unified control
Employees rarely contact the Helpdesk due to “network issues.” More often, they call because of pre-meeting stress when a small meeting room uses a different control system than a new large boardroom.
AV-over-IP enables centralized software-based control logic. With a single control core, the user interface on touch panels can be unified across all meeting rooms in the building, regardless of their size.
What starting a meeting with a single touch looks like is explained in our article on meeting room automation.
4. Full remote diagnostics and maintenance
Every device in the meeting room—for example, ceiling speakers, wall amplifiers, or microphones—receives a fixed static IP address within its network segment, similar to a standard network printer.
IT support teams and integrator technicians gain 100% remote diagnostic access. System status is visible at a glance directly from the office, eliminating the need to send a technician physically to the meeting room.
Is AV-over-IP technology secure for a corporate network?
A key requirement of modern enterprises is maintaining strict cybersecurity standards. Deploying a modern AV system must not introduce a compromise to IT security.
Video and audio streams are transmitted in encrypted form. Security is not ensured by the technology alone, but by the way it is deployed: a separate VLAN, controlled access and firewall configuration in cooperation with your IT department. MediaTech holds Certified Solution Provider and Global Quality Assurance certifications within the PSNI Global Alliance, which verify the quality of design and installation processes. The resulting security is always a joint responsibility of the integrator and the network administrator.
The criteria used to verify an integrator’s quality are explained in our article about PSNI standards for medium-sized businesses.
Frequently Asked Questions
What is AV-over-IP technology and how exactly does it work?
AV-over-IP, or Audio Visual over Internet Protocol, is an architecture that replaces conventional point-to-point audiovisual cabling. Video and audio signals from cameras and microphones are converted by dedicated hardware into IP packets in real time and transmitted to a central Layer 2 or Layer 3 network switch using standard gigabit CAT6a cabling with RJ-45 connectors.
Why does AV-over-IP reduce the workload of the IT helpdesk?
It removes several of the most common causes of IT support tickets. AV-over-IP uses Power over Ethernet for reliable power delivery instead of bundles of USB adapters and extension cables that can easily become disconnected beneath the table. It also provides a consistent control interface across meeting rooms and enables complete remote system diagnostics and maintenance.
Will a 4K AV-over-IP video stream overload a standard corporate network?
Not when the network is designed correctly. Audiovisual traffic is isolated within its own virtual local area network and prioritised using Quality of Service rules. Ordinary employee data traffic therefore does not disrupt the conference stream, and AV traffic does not interfere with normal business applications.
Is AV-over-IP transmission secure from a cybersecurity perspective?
Video and audio streams can be transmitted in encrypted form. Security, however, depends not only on the technology itself but also on the way it is deployed, including a separate VLAN, controlled access and appropriate firewall configuration in cooperation with the IT department. MediaTech holds Certified Solution Provider and Global Quality Assurance certifications within the PSNI Global Alliance, which verify the quality of its design and installation processes.
