Talk to an engineer →Who uses it, where it goes and how to install it
Written for the Uniarch SW-2226-LP from its own datasheet: 24 × 100 Mbps PoE ports (IEEE 802.3af/at, Mode B), one 1000 Mbps RJ45 uplink plus one 1000 Mbps Combo uplink, 250 W PoE budget with 30 W per port, up to 250 m in Surveillance mode, fanless 1U metal body with built-in AC power.
Who it is for
- Integrators with 17–24 camera projects — 24 PoE ports match a 24- or 32-channel NVR from one switch, and 24 typical 4 MP IR cameras at about 6 W use only 144 W of the 250 W budget.
- Warehouses, schools and car parks with some PTZs — With 250 W there is room for a mix: 20 fixed cameras at 6 W plus 4 mini PTZs at 13 W is 172 W, still below the 200 W (80%) mark where the PoE-MAX light starts to matter.
- Sites with far cameras on the perimeter — Surveillance (EXTEND) mode takes camera runs up to 250 m instead of 100 m, so fence-line and gate cameras can come straight back to the main cabinet without an outdoor switch.
- Projects that keep cameras apart from users — In Secure mode the 24 downlink ports can only talk to the two uplinks, so one infected or tampered camera cannot reach the others. It is also listed as NDAA compliant.
Where and how to install
- Rack position and heat — A 19-inch 1U unit, 440 × 189.8 × 44 mm and 2.15 kg, with no fan: it cools only through its metal case. Keep the vents clear and do not sandwich it tightly between an NVR and a UPS; the operating range is 0 °C to 45 °C and 10% to 90% humidity (non-condensing). Near a full 250 W load a closed cabinet in a hot room needs a cabinet fan.
- Power and UPS — Plug AC 100–240 V, 50/60 Hz straight into the switch; maximum consumption is 270 W. That is more than many small UPS units deliver, so size the UPS for 270 W plus the NVR and router, and check the UPS's watt rating, not only its VA.
- NVR on an uplink port, always — Connect the NVR to the 1000 Mbps RJ45 uplink and keep the Combo port for fibre or a link to the core switch. Never put the NVR on ports 1–24: they are 100 Mbps, and in Secure mode they can only talk to the uplinks, so the NVR would lose every camera.
- Cable lengths and all 8 wires — Camera runs: 100 m in Normal or Secure mode, up to 250 m in Surveillance (EXTEND) mode, with solid-copper Cat5e/Cat6 (not CCA). PoE is Mode B only, on pins 4/5/7/8, so terminate all 8 wires: a 4-wire cable carries data but no power. Copper uplinks are 100 m maximum; use a fibre SFP module in the Combo port for longer links.
- Grounding and surge — The datasheet lists no surge rating. Bond the rack and the switch chassis to the building earth, add Ethernet surge protectors on runs from poles and rooftops, and use fibre on the Combo port between buildings. With 24 outdoor cables on one switch, a single lightning hit can otherwise reach many ports at once.
- Use the priority ports — Ports 1–8 keep PoE power first if demand nears 250 W. Put entrances, cash desks and PTZs on ports 1–8, ordinary cameras on 9–24, and label the patch panel so the order survives later changes.
PoE budget: how many cameras it really powers
250 W across 24 ports is about 10.4 W per port on average: enough for a full set of fixed cameras (24 × 6 W = 144 W) plus a handful of mini PTZs. The 30 W per-port limit only tells you what one port can give; at a full 30 W the total budget is used up by 8 devices.

| Mounting / cooling | 19-inch rack 1U, 440 × 189.8 × 44 mm, fanless |
- Pick the SW-2226-LP for 17–24 cameras on one NVR, including up to about 4 mini PTZs: 20 × 6 W + 4 × 13 W = 172 W stays below the 200 W (80%) mark.
- For 16 cameras or fewer, the 16-port SW-2218-LP (150 W) costs less rack space per port used and is enough for fixed cameras.
- If more than 8 ports must run heavy 25–30 W PTZs, split them across two switches rather than relying on the priority ports to sort out an overloaded 250 W budget.
Camera draws of ~6 W (4 MP IR bullet/dome), ~13 W (mini PTZ) and 25–30 W (larger PTZ, heaters) are typical assumptions; check the max. power on each camera's datasheet. Budget, per-port, PoE-MAX and distance figures are from the Uniarch datasheet.
24-Port PoE Switch FAQ — SW-2226-LP
How many cameras can the SW-2226-LP power at full load?
All 24 PoE ports can power cameras from the 250W total budget — over 10W average per port, while typical fixed IP cameras draw 4–12W. Any single port can deliver up to 30W under IEEE 802.3af/at for PTZ or IR-heavy models, and ports 1–8 hold PoE priority.
Can I uplink to the NVR room over fiber?
Yes. Besides the 1000 Mbps GigaEthernet RJ45 uplink, the 1000 Mbps Combo port accepts either RJ45 copper or an SFP fiber module, so the 24 camera ports can aggregate over fiber. Switching capacity is 8.8 Gbps with 6.55 Mpps forwarding and a 16K MAC table.
How far can it push PoE to distant cameras?
In Surveillance (EXTEND) mode, PoE transmission extends up to 250 m per cable run for far perimeter cameras. Normal mode lets all ports intercommunicate, while Secure mode makes downlink ports talk only to the uplinks, isolating cameras from each other. Modes are switchable on the unit.
What are the rack size and power requirements?
It is a 19-inch 1U all-metal unit, 440 x 189.8 x 44 mm and 2.15 kg, with a built-in AC 100–240V, 50/60 Hz power supply — no external adapter. Maximum system draw is 270W at full PoE load, and the fanless design runs silently from 0 to 45 degC.
What switching level and compliance does the SW-2226-LP offer?
It is an L2 switch supporting IEEE 802.3, 802.3u, 802.3az, 802.3x and 802.3af/at, with PoE delivered in Mode B (pins 4/5/7/8). It is NDAA compliant, carries a 4 Mbit packet buffer, and the PoE-MAX LED lights when load passes 85% of the 250W budget.
Cameras draw more at night with IR or warm light on. Is the SW-2226-LP budget still enough for 24 of them?
Usually yes, but plan with the night figure, not the daytime one. 24 cameras at 8 W are 192 W, under the 200 W (80%) mark; at 10 W they are 240 W, close to the 250 W limit, and the PoE-MAX light will be on. Take each camera's maximum power from its datasheet, add it up, and keep the total under about 200 W; if demand ever exceeds 250 W, ports 1–8 are served first.
The SW-2226-LP lists only PoE Mode B. Will it power Hikvision, Dahua or other non-Uniarch cameras?
Yes, if they are standard IEEE 802.3af or 802.3at devices: a compliant camera must accept power on either pair, so Mode B (pins 4/5/7/8) works with any brand, up to 30 W per port, and any NVR brand works on the uplink. Two cases fail: 'passive' 12 V or 24 V PoE devices, and cables with only 4 wires on pins 1/2/3/6, which carry data but no power from this switch. Terminate all 8 wires on every run.
What do I give up when I put SW-2226-LP ports into Surveillance (EXTEND) mode for 250 m?
Mainly link speed. The datasheet states only the 250 m distance, but long-distance modes on PoE switches generally lower the port rate, commonly to 10 Mbps, which still carries one camera at a few Mbps (for example 4 MP H.265 at 4 Mbps) but not a 4K main stream at full bitrate. Use good solid-copper cable, put one camera per long run, and keep cameras within 100 m in Normal mode where you can; confirm the link rate with us before planning 4K on 250 m runs.
Is one Gigabit uplink on the SW-2226-LP enough for 24 cameras going to the NVR?
Yes. Even with 24 4K cameras at about 16 Mbps each (H.265), the total is 384 Mbps, well under the 1000 Mbps uplink; 24 4 MP cameras at about 6 Mbps are only 144 Mbps. The 8.8 Gbps switching capacity equals all 24 × 100 Mbps plus 2 × 1000 Mbps ports running in both directions, so the switch does not drop traffic. Put the NVR on the RJ45 uplink and use the Combo port for the link to the core switch or a remote viewing room.
Which SFP module fits the Combo port of the SW-2226-LP?
A 1000 Mbps (1.25G) SFP module, not a 10G SFP+. Match single-mode or multimode to your fibre and use the same type and wavelength, or a matching BiDi pair, at the other end; the module, not the switch, decides the distance. The Combo port works as RJ45 or SFP, not both at once, and the datasheet lists no approved module models, so tell us what is at the other end and we will supply a matched pair.
What is the difference between the SW-2226-LP and the SW-2218-LP, SW-2110-LP and SW-2106-LP?
The SW-2218-LP is its 16-port sibling in the same 440 × 189.8 × 44 mm 1U body: 150 W instead of 250 W, 165 W instead of 270 W maximum consumption, and PoE Mode A and Mode B listed instead of Mode B only; both have one Gigabit RJ45 and one Gigabit Combo uplink. The desktop SW-2110-LP (8 PoE ports) and SW-2106-LP (4 PoE ports) share a 60 W budget and have 100 Mbps uplinks only. Choose the SW-2226-LP when you have 17–24 cameras or need the extra 100 W.
