Professional AV Integration — Southwestern Ontario
Here's something that gets glossed over in almost every AV conversation: modern commercial AV is a network application. AVoIP, control systems, digital signage, IP cameras, sound masking, smart lighting, occupancy sensors — all of it lives on the network. The cabinet of switches in the back room isn't supporting your AV system; it is your AV system, in the same way the foundation is part of the house.
And yet most operators inherit a network that was sized to support a few computers and a printer, then bolt $80K of AV onto it and wonder why the system feels flaky. The most common AV failure we troubleshoot isn't broken hardware. It's a network that wasn't built for the job.
This guide explains, in plain English, what a properly built AV network actually looks like — and why your IT person and your AV integrator need to be talking to each other, not nodding at each other across a meeting.
Office traffic is bursty and forgiving — an email taking an extra 200ms doesn't matter. AV traffic is constant and unforgiving — a video stream that drops 200ms is a frozen screen. They're different jobs that require different network behavior, and a network optimized for one is rarely good at the other.
An AVoIP video stream is roughly the same load as a 4K Netflix stream — except it's running 24/7, multiplied by every screen in your venue, and it has to stay perfectly synchronized with the audio. A network that handles "the office" fine will routinely choke on this when somebody runs a software update during the dinner rush.
Managed, gigabit minimum (10G uplinks for larger AVoIP systems), with PoE+ on the AV ports. Not consumer "smart switches" — proper enterprise gear from Cisco, Aruba, Ubiquiti, or Netgear's commercial line.
Virtual networks that separate AV traffic from office, guest Wi-Fi, POS, and IoT. The AV stuff doesn't see the office stuff and vice versa. Critical for stability and security.
Many AV devices (cameras, control panels, network speakers, access points) draw their power from the network cable itself. Your switches need enough total PoE wattage to power them all without throttling.
Enterprise-grade access points placed by an actual site survey, not "wherever the closet was." iPad control panels, guest streaming, and POS all depend on Wi-Fi being right.
CAT6 or CAT6A throughout, properly terminated, properly tested. Not Cat5e, not "whatever was on the truck." Test results documented at install.
Sized for the AV streaming plus everything else. A single 50Mbps connection trying to support streaming sources, guest Wi-Fi, and POS will hit a wall.
A VLAN is a way to make one physical network behave like several separate networks. Your AVoIP traffic lives on its own VLAN. Your office computers live on a different VLAN. Your guest Wi-Fi lives on a third. Even though they share the same switches and cables, they can't see each other and don't compete for the same resources. It's how you take an office network and turn it into reliable AV infrastructure without spending a second time.
Power over Ethernet (PoE) is the technology that lets a network cable carry both data and electrical power to a device. Modern AV uses it everywhere: AVoIP encoders, PTZ cameras, control panels, access points, network speakers, IP intercoms. Each device pulls a certain amount of wattage. Each switch has a maximum total PoE budget. Exceed that budget and devices stop powering up.
Switch is rated for 195W of PoE. Devices on it pull 230W combined. The switch quietly throttles or drops the most recently connected device when load peaks. Symptom: random AV devices going offline at peak hours, mysteriously coming back overnight. Diagnosis: PoE budget exhausted.
⚠️ MOST COMMONTotal PoE devices add up to ~60% of the switch's rated PoE budget, leaving headroom for spikes and future additions. Switches are rated for "PoE+" (30W per port) or "PoE++" (60W+ per port) where high-draw devices live. Budget calculated and documented.
✅ HEADROOM PLANNEDIf your iPad control panel takes 8 seconds to respond to a tap, it's almost never the iPad. It's Wi-Fi coverage, AP placement, channel congestion, or a 2.4GHz band saturated by every Bluetooth device in a five-block radius.
A real Wi-Fi deployment in a commercial space includes:
All figures in Canadian dollars. Includes hardware and install. Excludes structural cabling, which is typically a separate line item with the GC.
The honest answer: your AV integrator and your IT person, together, with one of them owning final responsibility. The most common failure mode we see is when they're both involved but neither one is responsible — the AV system blames the network, IT blames the AV gear, and the operator pays both of them to point fingers.
The AV company designs, installs, and maintains the network as part of the AV scope. Single point of accountability. Best for venues without a dedicated IT team. Most common in hospitality.
Your IT team runs the network, but the AV integrator provides written specifications: VLANs, PoE budget, AP placement, port assignments. Best for offices and larger organizations with real IT staff. Requires real coordination — not a one-email handoff.
1. "Our existing network is fine." It might be — but you don't know without checking. Insist on PoE budget calculations, switch documentation, and bandwidth headroom analysis before committing to an AV install on top of existing infrastructure.
2. Consumer routers in commercial spaces. A $200 ASUS or Netgear router from Best Buy is not network infrastructure. Commercial AV needs commercial gear with proper management, monitoring, and capacity.
3. No documentation. When something fails at 11pm, the difference between a 30-minute fix and a 4-hour outage is whether somebody can find a network diagram. Insist on it at handoff.
4. Skipping the cable test results. CAT6 cabling needs to be physically tested with a real tester (Fluke or equivalent) and the results recorded. "It seems to work" isn't a test.
5. Treating Wi-Fi as the AV control path. Wired everything wired-able. Wi-Fi is for guests and tablets. Putting an AVoIP encoder on Wi-Fi is asking for trouble.
A handout for your IT person, your GC, or whoever you're trying to convince that "the network matters."
