An 8-Port PoE Switch With a 60W Budget Cannot Power 8 Cameras: The Spec That Decides How Many Devices You Actually Get
UGREEN's 10-port PoE switch offers up to 30W per port and a total budget of 60W — which works out to 7.5W per port if all eight are used. When the budget is exceeded it cuts ports in priority order from 8 down to 1. Count watts, not ports.
The port count is not the capacity
Power over Ethernet switches are sold on port count. It is the wrong number.
UGREEN’s 10-port PoE switch lists at $59.99 and publishes:
| Spec | Figure |
|---|---|
| PoE ports | 8, Gigabit, 802.3at/af |
| Uplink ports | 2, Gigabit |
| Per-port maximum | up to 30W |
| Total PoE budget | 60W |
| Speed | 1000Mbps on all ports |
| Management | Unmanaged, three modes (Standard / VLAN / Extend) |
| Overload behaviour | Cuts ports in priority order 8 → 1 |
Read the two bolded rows together. Eight ports at up to 30W each, sharing a 60W total. Two devices can take 30W. Or eight can average 7.5W. What you cannot have is eight devices at 30W, and nothing about “8-Port PoE, 30W per port” on a product listing says so.
This is the same shared-budget pattern that governs multi-port USB chargers, and it catches people the same way.
What your devices actually draw
The useful exercise is to add up real consumption before counting ports.
| Device | Typical PoE draw |
|---|---|
| Fixed indoor camera | 4–8W |
| Outdoor camera (IR, no heater) | 6–12W |
| Outdoor camera with heater | 12–25W |
| Pan-tilt-zoom camera | 15–30W |
| Wi-Fi access point (dual-band) | 12–20W |
| Wi-Fi 6/7 access point | 20–30W |
| VoIP phone | 3–7W |
| PoE door intercom | 8–15W |
Against a 60W budget:
- Six modest indoor cameras at 7W each = 42W. Comfortable.
- Four outdoor cameras with heaters at 20W = 80W. Over budget.
- Two Wi-Fi 6 access points plus three cameras = roughly 50–80W depending on the APs. Marginal.
- One PTZ camera plus four indoor cameras = roughly 58W. Right at the edge.
Winter is where budgets get exceeded, because camera heaters only draw power when it is cold. A setup that has worked all summer can start dropping ports in the first hard freeze — which is exactly when you want the cameras working.

The port-priority behaviour is a feature — use it
UGREEN states that if power exceeds 60W, the switch cuts ports in priority order from 8 down to 1.
That is good design. An overloaded PoE switch that browns out unpredictably is far worse than one that sheds load in a known sequence. But it only helps if you wire accordingly.
Assign ports by how much you would mind losing the device:
- Port 1: the thing that must never go down — the front door camera, the primary access point.
- Ports 2–4: important but survivable.
- Ports 7–8: the garage camera, the spare AP, anything you would not notice for a day.
Most people cable in the order the devices were installed. Ten minutes of thought at install time converts a random failure into a predictable one.
802.3af, 802.3at, and why the standard matters
The switch supports 802.3at/af, which covers both common PoE generations:
- 802.3af (PoE) — up to roughly 15.4W at the source.
- 802.3at (PoE+) — up to roughly 30W at the source.
Note “at the source.” Cable resistance means the device at the far end receives less than the switch sends, and the gap grows with cable length. A 30W port over a long run may deliver noticeably less than 30W to the camera. If a device is borderline on power and far away, that combination is where intermittent reboots come from.
Devices needing more than 30W require 802.3bt, which this class of switch does not provide.
The three modes, and when to use them
The switch is unmanaged, with a physical mode selector:
Standard. Everything on one network, full Gigabit. The default and the right choice for most homes.
VLAN. Isolates the PoE ports from each other and from the uplink in a simple fixed arrangement. The reason to care: security cameras are among the least trustworthy devices on a home network. They are rarely updated, frequently phone home, and have a poor track record. Putting them where they cannot see your laptop is worthwhile, and this mode does it without a web interface.
Extend. Roughly doubles the standard 100-metre cable reach at reduced speed, typically 10Mbps. For a camera at the end of a long driveway, 10Mbps is ample — a 1080p stream fits comfortably. For an access point it is not.
An unmanaged switch with these three modes covers most home requirements. If you need per-port VLAN assignment, link aggregation or monitoring, you want a managed switch and a different budget.
What to buy
Three to six indoor cameras. This switch at $59.99. Add up the wattage first; you will almost certainly be under 60W.
Outdoor cameras with heaters, or several Wi-Fi 6 access points. Look for a higher power budget — 120W or more. The port count you need may be small; the watts are what you are buying.
One or two PoE devices. A single PoE injector costs far less than a switch and does the same job.
No PoE devices at all, you just need more ports. UGREEN’s plain Gigabit switches are considerably cheaper. PoE circuitry is most of the cost here, and there is no reason to pay for it unpowered.
You want cameras isolated from your computers. This switch’s VLAN mode is a genuine reason to choose it over a plain switch, and it is the feature most likely to matter in a year.

Device power figures in the table above are typical ranges across the category, not measurements of specific products. Always use the wattage printed on your own devices’ specifications — PoE camera consumption varies widely with IR illumination, heaters and motor use.
Specifications are manufacturer-published. We have not tested the overload behaviour, the VLAN isolation or the extend mode on this switch.
PoE budget figures describe power available at the switch. Delivered power at the device is lower and falls with cable length and cable quality.

Frequently Asked Questions
- Q: How many PoE cameras can a 60W switch run?
- A: Count the cameras' actual draw rather than the port count. Typical fixed indoor PoE cameras draw roughly 4-8W, outdoor cameras with heaters and IR draw more, and pan-tilt models more again. A 60W budget realistically runs six to eight modest cameras, or three to four demanding ones — not eight of anything power-hungry.
- Q: What happens when I exceed the power budget?
- A: On UGREEN's switch, it cuts ports in priority order from port 8 down to port 1 to prevent overload. That is well-designed behaviour, and it means port assignment matters: put the device you least want to lose on port 1 and the most expendable on port 8.
- Q: What is the difference between 802.3af and 802.3at?
- A: 802.3af (PoE) supplies up to about 15.4W at the source; 802.3at (PoE+) raises that to about 30W. A switch supporting both can feed either type of device. The higher figure is what pan-tilt cameras, dual-band access points and PoE lighting need.
- Q: Do I need a managed switch?
- A: For a home network, usually not. UGREEN's unit is unmanaged with Standard, VLAN and Extend modes selected by a physical switch, which covers the common needs — isolating cameras onto their own segment, or trading speed for cable distance — without a web interface to configure.
- Q: Can I use longer cable runs than 100 metres?
- A: Only with a switch that offers an extend mode, and only at reduced speed. Extend modes typically drop the affected ports to 10Mbps in exchange for roughly double the standard 100m reach. For a camera at the end of a long driveway that trade is usually worth it; for an access point it is not.
