Talk to an engineer →Who uses it, where it goes and how to install it
Written for the Uniarch SW-2218-LP from its own datasheet: 16 × 100 Mbps PoE ports (IEEE 802.3af/at), one 1000 Mbps RJ45 uplink plus one 1000 Mbps Combo uplink, 150 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
- Installers with 9–16 fixed cameras — 16 PoE ports match a 16-channel NVR, and 16 typical 4 MP IR cameras at about 6 W use only 96 W of the 150 W budget, leaving room for one or two mini PTZs.
- Shops, offices and small hotels with a network cabinet — The fanless 1U body (440 × 189.8 × 44 mm, 1.99 kg) is silent next to staff, and AC 100–240 V is built in, so there is no external power brick to hide in the cabinet.
- Sites with a few far cameras: gates, car parks, perimeter — Surveillance (EXTEND) mode stretches camera runs up to 250 m instead of the usual 100 m, so a gate camera 150 m from the cabinet needs no extra switch or power point on the way.
- Projects that keep cameras apart from users — In Secure mode the 16 downlink ports can only talk to the two uplinks, so cameras cannot reach each other and a laptop plugged into a spare PoE port cannot browse the cameras. It is also listed as NDAA compliant.
Where and how to install
- Rack or shelf, with free air — It is a 19-inch 1U unit with no fan, so it cools only through its metal case. Keep the vents clear and leave space between it and a hot NVR; the operating range is 0 °C to 45 °C and 10% to 90% humidity (non-condensing). In a closed cabinet in a hot room add a cabinet fan, and do not put it in an outdoor box that drops below 0 °C.
- Power and UPS — Plug AC 100–240 V, 50/60 Hz straight into the switch; maximum consumption is 165 W. Size the UPS for 165 W plus the NVR and router, otherwise every camera goes dark at the first power cut.
- NVR on an uplink port, always — Connect the NVR to the 1000 Mbps RJ45 uplink or the Combo port, never to ports 1–16. The uplinks are the only Gigabit ports, and in Secure mode a PoE port can only talk to the uplinks, so an NVR on port 5 would lose every camera.
- Cable lengths — Camera runs: 100 m in Normal or Secure mode, up to 250 m in Surveillance (EXTEND) mode, with solid-copper Cat5e/Cat6 (not CCA). Copper uplinks are 100 m maximum; for a longer link to the NVR room put a fibre SFP module in the Combo port. Outdoors, keep cable joints in a junction box.
- Grounding and surge — The datasheet lists no surge rating. Bond the rack and the switch chassis to the building earth, and add Ethernet surge protectors on runs that come from poles or rooftops. Between buildings, fibre on the Combo port avoids ground-potential problems on long copper.
- Use the priority ports — Ports 1–8 keep PoE power first when demand nears 150 W. With this budget that can really happen, so put entrances, cash desks and PTZs on ports 1–8, less important cameras on 9–16, and label the patch panel so the order is kept.
PoE budget: how many cameras it really powers
150 W across 16 ports is about 9.4 W per port on average: plenty for ordinary fixed cameras (16 × 6 W = 96 W), but not for a full bank of PTZs. The 30 W per-port figure says what one port can give; the 150 W total says how many heavy loads fit at the same time, and at a full 30 W that is only 5.

- Pick the SW-2218-LP for 9–16 fixed cameras on a 16-channel NVR, with at most two or three mini PTZs: 14 × 6 W + 2 × 13 W = 110 W stays under the 80% mark of 120 W.
- If the 16 ports must feed several PTZs or high-draw cameras, choose a 16-port model with a larger budget, such as the Uniview NSW2020-16T1GT1GC-POE-IN, instead of running this switch near 150 W.
- For 17–24 cameras use the 24-port SW-2226-LP (250 W); for 8 cameras or fewer the desktop SW-2110-LP is enough.
Camera draws of ~6 W (4 MP IR bullet/dome), ~13 W (mini PTZ) and 25 W or more (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.
16-Port PoE Switch FAQ — SW-2218-LP
How many cameras can the SW-2218-LP support?
It has 16 PoE ports with a 150W total budget — roughly 9W average per port, comfortable for typical 4–12W fixed IP cameras as long as the total stays under 150W. Any port can deliver up to 30W for PTZ or IR-heavy models, and ports 1–8 hold PoE priority.
What uplinks does it offer toward the NVR?
Two gigabit uplinks: one 1000 Mbps RJ45 port plus one 1000 Mbps Combo port. With 7.2 Gbps switching capacity, 5.36 Mpps forwarding, a 16K MAC table and 4 Mbit buffer, the 16 fast-Ethernet camera ports aggregate cleanly into a gigabit backbone to the NVR or core switch.
Can it feed cameras beyond the usual cable distance?
Yes — in Surveillance (EXTEND) mode, PoE transmission extends up to 250 m per run for distant gate and perimeter cameras. Two other modes are available: Normal, where all ports intercommunicate, and Secure, where downlink ports talk only to the uplinks for camera isolation.
Can it be rack-mounted and how is it powered?
Yes — it is a 19-inch 1U unit (440 x 189.8 x 44 mm, 1.99 kg) with a built-in AC 100–240V, 50/60 Hz power supply, so no external adapter is needed. Maximum draw is 165W. The fanless all-metal chassis runs silently from 0 to 45 degC.
Which PoE standards and wiring modes does it support?
It is an unmanaged switch following IEEE 802.3af/at, delivering PoE in both Mode A (pins 1/2/3/6) and Mode B (pins 4/5/7/8) at up to 30W per port. It is NDAA compliant, and the PoE-MAX LED warns when load passes 85% of the 150W budget.
The SW-2218-LP gives 30 W per port but only 150 W in total. Can every port run a 30 W device?
No. Any single port can deliver up to 30 W, but all ports share 150 W, so only 5 devices can draw a full 30 W at the same time (5 × 30 W = 150 W). In practice plan to stay below about 120 W (80%), for example 14 fixed cameras at 6 W plus 2 mini PTZs at 13 W = 110 W. If demand goes over the budget, ports 1–8 are served first.
What do I give up when I switch the SW-2218-LP to Surveillance (EXTEND) mode for 250 m?
Mainly speed. The datasheet states only the 250 m distance, but long-distance modes on PoE switches generally work by lowering the port link rate, commonly to 10 Mbps. One camera stream at a few Mbps (for example a 4 MP H.265 main stream at 4 Mbps) fits; do not chain extra devices on a long run, use good solid-copper cable, and keep runs under 100 m in Normal mode where you can. Confirm the link rate with us before planning 4K cameras on 250 m runs.
Are 100 Mbps camera ports and one Gigabit uplink on the SW-2218-LP enough for 16 4K cameras?
Yes. A single 4K camera in H.265 usually streams well under 16 Mbps, far below 100 Mbps. The total is what matters: 16 cameras at 16 Mbps are 256 Mbps on the 1000 Mbps uplink to the NVR, about a quarter of it. The 7.2 Gbps switching capacity equals all 16 × 100 Mbps plus 2 × 1000 Mbps ports running in both directions, so the switch itself is not the bottleneck.
Will the SW-2218-LP power Hikvision, Dahua or other non-Uniarch cameras and work with their NVRs?
Yes. It is an unmanaged Ethernet switch, so any NVR brand works on the uplink, and it powers any camera, access point or intercom that is a standard IEEE 802.3af or 802.3at device, up to 30 W per port. It will not power 'passive' 12 V or 24 V PoE devices that skip standard PoE detection, and devices needing more than 30 W (802.3bt) are outside its range.
Which SFP module do I need for the Combo port on the SW-2218-LP?
A 1000 Mbps (1.25G) SFP module, not a 10G SFP+. Choose single-mode or multimode to match your fibre and use the same type and wavelength (or a matching BiDi pair) at the other end; the module sets the distance, not the switch. A Combo port is either 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 match the pair.
SW-2218-LP, SW-2226-LP or SW-2110-LP: which one should I buy?
Count cameras first. The SW-2218-LP covers 9–16 cameras with 150 W and Gigabit uplinks in a 1U rack body. The SW-2226-LP is the same family with 24 PoE ports and 250 W, for 17–24 cameras or more PTZs. 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, so they suit small sites of up to 8 cameras.
