PoE Switch Buyer's Guide for Philippine Offices: What to Specify When Adding IP Cameras and Wi-Fi APs
Power over Ethernet allows a network switch to deliver electrical power to connected devices over the same Cat5e/Cat6 cable used for data. The IP camera or Wi-Fi access point at the far end of the cable receives both its network connection and its operating power through a single cable run — no separate power outlet, no power adapter at each device location.
For Philippine offices adding IP surveillance cameras or enterprise Wi-Fi access points, PoE is not optional — it is the standard power delivery method for these devices. Selecting a PoE switch requires understanding the power standards, the total power budget, and the port count you need.
PoE Standards: 802.3af, 802.3at, 802.3bt
Three IEEE standards govern PoE, differing in the power they deliver per port:
| Standard | Also Called | Max Power Per Port | Typical Use |
|---|---|---|---|
| 802.3af | PoE | 15.4W (12.95W at device) | IP phones, basic IP cameras, wireless sensors |
| 802.3at | PoE+ | 30W (25.5W at device) | Wi-Fi 5/6 access points, PTZ cameras, video intercoms |
| 802.3bt | PoE++ / Hi-PoE | 60W or 90W | Wi-Fi 6E APs, multi-radio APs, high-power outdoor APs |
The practical guide for Philippine office deployments:
- IP cameras (fixed, indoor): typically 5–15W — 802.3af is sufficient
- IP cameras (PTZ, with IR, outdoor): typically 15–25W — 802.3at required
- Wi-Fi 6 access points (Ubiquiti U6 Pro, Aruba Instant On AP25): 15–25W — 802.3at required
- Wi-Fi 7 access points (high-end): up to 30–60W — 802.3bt for some models
- IP phones: 3–7W — 802.3af sufficient
Verify the PoE requirement of every device before selecting the switch. A switch with only 802.3af ports cannot power a device that requires 802.3at — it will deliver reduced power and the device may not function or may operate in a reduced-performance mode.
Total Power Budget: The Most Important Specification
Every PoE switch has a total power budget — the maximum watts it can deliver across all PoE ports simultaneously. This is separate from (and more limiting than) the per-port maximums.
Example: An 8-port PoE+ switch (802.3at, 30W per port) might have a total power budget of 65W or 130W. At 65W total, you cannot power even 3 devices at full 25W each. At 130W, you can comfortably power 5 devices at 25W each.
Total power budget calculation:
- List all PoE-powered devices and their actual power draw (from spec sheet, not maximum rating)
- Sum the watts: this is your minimum required power budget
- Add 20% headroom for future expansion
- Select a switch with a total power budget above this figure
Example for a 12-camera + 4 AP Philippine office:
- 12 indoor IP cameras at 10W each = 120W
- 4 Wi-Fi 6 APs at 22W each = 88W
- Total: 208W
- With 20% headroom: 250W minimum power budget
A 24-port PoE+ switch with 185W total budget would be insufficient. A 24-port PoE+ switch with 370W total budget provides comfortable headroom.
Port Count: How Many Do You Need?
Count every PoE-powered device and add 25% for expansion:
- Each IP camera = 1 PoE port
- Each Wi-Fi access point = 1 PoE port
- Each IP phone = 1 PoE port
- Each PoE-powered device (video intercom, door access reader with reader interface) = 1 PoE port
Non-PoE devices (servers, NAS, desktop PCs, printers) use regular switch ports — they do not consume PoE power budget but do consume port count.
For a Philippine office with 8 cameras, 4 APs, and 20 workstations/servers, a 24-port switch (8 + 4 PoE devices + 20 non-PoE + 2 uplink ports = 34 connections) requires a 48-port switch or two 24-port switches connected via uplink.
Managed vs Unmanaged PoE Switches
Unmanaged PoE switches:
- Plug and play — no configuration required
- No VLAN support, no traffic prioritisation, no per-port monitoring
- Appropriate for simple single-VLAN networks with only cameras and APs
- Philippine market price: ₱4,000–15,000 for 8–16 port models
Managed PoE switches:
- Support VLANs — separate camera traffic from staff traffic (security best practice)
- QoS (Quality of Service) — prioritise VoIP traffic for IP phone deployments
- Per-port PoE monitoring — see actual power consumption per device
- Remote management — configure and monitor via web interface or cloud dashboard
- SNMP — integrate with network monitoring tools
- Philippine market price: ₱12,000–80,000 depending on port count and features
When you need a managed switch:
- Deploying VLANs (cameras on separate VLAN from staff network — recommended for security)
- IP phone deployments requiring QoS
- Multi-SSID Wi-Fi with VLAN tagging (most enterprise APs require a managed switch)
- Environments with network monitoring or management requirements
For most Philippine SME deployments adding cameras and APs to an existing network: a managed switch is recommended — the VLAN separation between camera traffic and corporate traffic is a meaningful security improvement and most enterprise-grade APs (Ubiquiti UniFi, Aruba Instant On) expect a managed switch with VLAN tagging.
Recommended PoE Switches for Philippine Office Deployments
Entry — Unmanaged (simple camera/AP deployment, no VLAN requirements)
TP-Link TL-SG1008P (8-port, 4 PoE+, 55W budget): ₱3,500–5,000 — basic small office with 2–3 cameras and 1 AP
Netgear GS308P (8-port, 4 PoE, 53W budget): ₱4,000–6,000 — similar application
Mid-Range — Managed (VLAN, QoS, monitoring)
Ubiquiti UniFi USW-24-PoE (24-port, 16 PoE+, 95W budget): ₱18,000–25,000 — ideal for UniFi camera + AP deployments; managed via UniFi Network dashboard
Ubiquiti UniFi USW-Pro-24-PoE (24-port, 16 PoE+, 400W budget): ₱35,000–45,000 — for high device count with adequate power budget
Aruba Instant On 1930 series: ₱15,000–35,000 depending on model — managed via Aruba Instant On cloud; strong SME option
Enterprise
Cisco Catalyst 1000 Series (24/48 port, PoE+): ₱45,000–120,000 — enterprise-grade, SNMP, full management for larger deployments

PoE Switch and UPS: Power Protection
A PoE switch is network-critical infrastructure — if it loses power, all connected cameras and APs lose power simultaneously. Include the PoE switch in your UPS protection.
PoE switch power consumption:
- The switch itself draws 15–30W for its own operation
- Plus the total PoE power delivered to connected devices
Example total draw for a 24-port managed PoE+ switch at 60% load:
- Switch base power: 25W
- PoE devices: 150W
- Total: ~175W — factor this into UPS sizing
A PoE switch delivering 250W of PoE power requires a UPS rated for at least 350–400W to account for switch base power and safety margin.
