What a PoE switch does on an event network
A switch is the hub that wired equipment plugs into. The router has only a handful of ports; the switch multiplies them so every access point, camera, POS station and stream encoder has a cable home. A PoE switch adds power to those ports, which is what lets an access point sit on a pole or a camera on a fence line with nothing but a network cable running to it.
Each port can also be assigned to a network. A port feeding a payment desk sits on the payments VLAN, a camera's port sits on the camera VLAN, and access point ports carry several networks at once. That port plan is set up before the hire, so the person plugging in a cable on the day doesn't need to know what a VLAN is.
Planning PoE switch ports
Count every wired device, then add spares. A typical port plan looks like this:
| Port group | What plugs in | Network |
|---|---|---|
| Uplink | Cable to the router | All networks |
| Access points | One port per indoor or outdoor access point, powered by PoE | Staff, guest, payments, devices |
| Payments and ticketing | Wired EFTPOS bases, POS stations, ticketing desks | Payments |
| Stage and devices | Stream encoders, presenter laptops, screens, printers | Devices |
| Cameras | CCTV cameras powered by PoE, plus the recorder | Cameras |
| Spares | Left free for late additions and moved stands | As needed |
Distance matters as much as port count. Cable runs have a length limit, so a large hall or field may need a second switch closer to the far access points.
When to hire a PoE switch, and when you don't need one
You need one whenever the plan uses cabled access points, outdoor access points or CCTV cameras, or when more than a couple of wired devices need connecting near the router. On larger sites, a second switch at the far end of a hall shortens cable runs and keeps the layout tidy.
You probably don't need one for a small mesh WiFi set-up, where nodes link wirelessly and plug into normal power, or for a single 4G/5G router serving a few staff. If you're not sure which set-up fits, the event network planner is a quick first pass.

PoE switch hire specs
Power over Ethernet
Supplies power on the ports to access points, cameras and other PoE devices, with the switch's total power budget checked against everything plugged in.
VLAN-aware ports
Each port can carry one network or several, matching the networks configured on the router.
Mains powered
The switch itself needs a power point in a dry, secure spot, usually beside the router and away from the public.
Spare capacity
Ports and power budget held back for additions on the day, such as an extra screen or a moved registration desk.
How switch hire fits with installation and support
Port plan agreed
From your floor plan and device list, we decide how many switches, where they sit and which port serves what.
Configured before the hire
VLANs, port assignments and PoE settings are set and checked before the equipment leaves us.
Installed with the network
The switch goes in with the router, access points and any cameras, and every port in use is tested.
Changes during the hire
Spare ports make an extra wired stand or camera quick to add; how changes are handled is part of the support level agreed in your plan.
Pack-down
The switch comes out with the rest of the network at the end of the hire.
Questions people ask
What is a PoE switch?
A PoE switch is a network switch that also supplies power through its network ports, using Power over Ethernet. One cable then carries both data and power to an access point, security camera or other PoE device. That removes the need for a power point at every device, which is why PoE switches sit at the centre of many event and temporary-site networks.
How many ports does my PoE switch need?
Count one port for the router uplink, one per access point, one per camera, plus any wired payment, ticketing and stage devices. Then add spare ports for late additions and moved stands. A switch with exactly enough ports leaves no room for the extra screen or camera that turns up at bump-in. We work out the port plan with you before the hire.
Can a PoE switch power security cameras?
Yes. Many security cameras run on Power over Ethernet, so the switch powers them over the same cable that carries their video. On our installs, cameras sit on their own VLAN through dedicated switch ports, separate from guest and staff WiFi. When cameras and WiFi are hired together, we reserve PoE ports for the cameras in the same plan. See CCTV camera hire.
Do I need a network switch if I'm only using WiFi?
Often, yes, because the WiFi still has to connect back to the router. Cabled access points each need a switch port, and PoE powers them at the same time. A small mesh set-up may not need one, since nodes link wirelessly and only the first node connects to the router. Your floor plan and device list decide which applies.
Can I hire a PoE switch on its own?
A PoE switch can be hired on its own if you already have access points or cameras and need ports and power for them. Tell us what you're connecting, how many devices and how far apart they are, and we'll check the switch has enough ports and power budget. Configuration and hire terms are set out in your written quote.
