A PoE switch powers your access points, IP cameras and IP phones through the same cable that carries their data — one cable per device, no power sockets in the ceiling, no electrician. Choosing the right one comes down to three numbers: how many ports, how many watts, and whether you need it to be smart. This guide gives you the five-minute method we use when quoting networks in Dubai, with current UAE prices for every switch mentioned.
Step 1 — Count your powered devices (then add two)
List everything that will draw power from the switch: each access point, each camera, each IP phone. Add at least two spare ports — networks only ever grow. Four powered devices today means an 8-port PoE switch, not a 4-port.
Step 2 — Do the watts maths
Every switch has a total PoE budget shared across its ports. Typical draws: an IP phone 3–5W, a camera 5–12W, a WiFi 6 access point 15–25W. Add your devices’ needs, then keep 30% headroom. Example: 4 access points (≈80W) + 4 cameras (≈40W) = 120W needed — so a switch with a 150W+ budget, not a 60W one. Running a budget at its ceiling is the classic cause of cameras that reboot at night.
Step 3 — Smart or simple?
A managed switch lets you separate CCTV from office traffic (VLANs), restart a frozen camera remotely by power-cycling its port, and see per-port usage. For any business network we recommend managed — the price difference is small and the control pays for itself the first time a camera hangs.
Our recommendations by scenario
| Scenario | Switch | Why | UAE price |
|---|---|---|---|
| Small shop — up to 4 PoE devices | MikroTik RB260GSP | 5 ports, 4 with PoE-out, tiny and reliable | AED 201.25 |
| Office with UniFi WiFi — up to 4–6 devices | UniFi USW-Lite-8-PoE | 8 ports, 4x PoE+, lives in the UniFi dashboard | AED 529 — in stock |
| Mixed office + CCTV — up to 8 powered devices | MikroTik CRS112-8P-4S | 8 PoE-out ports + 4 SFP, full RouterOS control | AED 713 — in stock |
| Whole floor — APs, phones and cameras together | MikroTik CRS328-24P-4S+RM | 24 PoE ports, 4x 10G SFP+ uplinks, rackmount | AED 2,001 — in stock |
| High-speed backbone, no PoE needed | MikroTik CRS326-24G-2S+ | 24 gigabit ports + 2x 10G SFP+, pair with adapters | AED 713 — in stock |
One or two devices only? Skip the switch
Powering a single access point or camera doesn’t need a PoE switch at all — a Ubiquiti 48V 24W PoE adapter (AED 71.30, in stock) does the job for one Ubiquiti device, and the 50V 60W version (AED 126.50) handles hungrier hardware.
Three mistakes we see every month
Buying by ports, ignoring watts. An 8-port switch with a 60W budget cannot feed six WiFi 6 access points — count watts first. Mixing PoE standards blindly. Older Ubiquiti gear uses 24V passive power while modern equipment expects 802.3af/at — check before you plug, the wrong voltage can kill a device. No uplink headroom. If 20 cameras funnel into a gigabit uplink, the uplink is your bottleneck — the SFP+ ports on the CRS328 and CRS326 exist exactly for this.
