The power-budget maths

Every PoE switch has two numbers: the ports, and the total watts it can deliver across them. The second number is the one that decides whether your cameras come up.

• Cameras: a fixed dome or bullet draws 5–8 W; a PTZ or a camera with heaters and IR arrays draws 12–25 W. Budget 12 W per camera unless the datasheet says less.
• Wi-Fi access points: 8–12 W for Wi-Fi 5; 15–20 W for Wi-Fi 6 and 6E with all radios on.
• Desk phones: 3–7 W.

Add them up, then add 20% for start-up and for the camera the client adds next year. Eight 12 W cameras are 96 W; with two Wi-Fi 6 access points they are 126 W; with headroom, 150 W. Most 8-port PoE switches deliver 60–120 W in total. A 16-port PoE switch with a 150–250 W budget is the right buy for that site — the port count is a by-product.

Which PoE switch is best for CCTV?

The one whose budget covers the cameras with 20% to spare, that is rack-mountable if there is a cabinet, and that is managed if the cameras share the network with anything else. Managed means VLANs: the cameras and the recorder live on their own network, invisible to the office and the guest Wi-Fi, which is both a security requirement and the only way to keep a camera firmware bug from taking the phones down. A 16-port managed PoE switch around R 4 190 or a 24-port around R 5 235 covers most small sites.

For a single workshop with four cameras and nothing else on the switch, an unmanaged 8-port PoE unit around R 1 575 does the job.

Four traps

1. PoE versus PoE+ versus PoE++. 802.3af (PoE) gives 15.4 W per port; 802.3at (PoE+) gives 30 W; 802.3bt (PoE++) gives 60–90 W. A PTZ camera or a Wi-Fi 6E access point wants PoE+. Check the standard, not the logo.
2. The 100 m rule. Ethernet stops at 100 m of cable — including the patch leads. Past that, put a switch in a wall-mount cabinet at the far end, or run fibre with SFP uplinks. Between buildings, always fibre: copper carries lightning.
3. The uplink. Sixteen cameras on 1 Gbps ports feeding one 1 Gbps uplink to the recorder is fine; sixteen 4K cameras and the office through the same port is not. Look for SFP+ or at least two uplinks on anything past 16 ports.
4. Heat and fans. A fully loaded 24-port PoE switch dissipates real heat. In a sealed wall cabinet it will throttle or fail; choose the perforated door, and read the cabinet guide before you mount it.

Managed or unmanaged?

Unmanaged: plugs in, works, no configuration, no VLANs. Right for one office, one workshop, a handful of devices that all belong together. Managed (or smart/lite-managed): VLANs, QoS for voice, link aggregation, monitoring. Required the moment cameras, phones or guests share the switch. The price difference in the bands above is usually a few thousand rand — less than one call-out to diagnose a network the cameras have flooded.

What this means for your budget

A 24-port managed PoE switch at R 5 235 median plus two Wi-Fi 6 access points at R 1 995 median covers most offices to 40 seats. Spend on the uplink and surge protection before you spend on the next tier of switch.
