Overview
The NSW2020-16T1GT1GC-POE-IN is an unmanaged 19-inch rack-mount Fast Ethernet PoE switch with 16 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus a 1000Mbps RJ45 uplink (G2) and a 1000Mbps Combo RJ45/SFP uplink (G1/SFP1), built for machine-room and wiring-closet camera aggregation. It delivers a 250 W total PoE budget (30 W max per port, IEEE 802.3af/at, Mode B pinout) over a 7.2 Gbps switching fabric with 5.36 Mpps forwarding, a 4M bit packet buffer and a 16K MAC address table, cooled by a single internal fan and powered from a built-in AC 100–240V supply (265 W max). The all-metal 440×195×44 mm 1U chassis (2.12 kg) runs from 0°C to 45°C and switches between Default (Normal), VLAN (Secure, downlink-to-uplink only, with PD keepalive to reboot unresponsive PoE cameras) and EXTEND (250 m surveillance reach) via a front-panel slide switch — no management software required, NDAA compliant.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
16-Port PoE Aggregation for a Full NVR Channel Bank16 PoE-enabled ports feed a full 16-channel NVR from a single 1U switch — power and connect an entire camera bank without splitting cabling across multiple small switches in the rack.
Priority Ports 1-8 Protect Half the Camera Bank Under LoadPorts 1-8 carry PoE power priority, so entrance, server-room or other critical cameras on those ports keep drawing power first if total demand approaches the 250 W budget across all 16 ports.
VLAN Secure Mode with PD Keepalive for Unattended Equipment RoomsFlip the front-panel switch to VLAN (Secure) mode so downlink ports can only reach the uplink — and let PD keepalive auto-reboot any camera that stops responding, cutting truck rolls to remote server rooms and wiring closets.
EXTEND Mode Reaches a 250 m Perimeter Camera From the Same RackFlip the same front-panel switch to EXTEND (surveillance mode) and push power plus data up to 250 m for a single gate, fence-line or driveway camera — no need for a separate mini switch or repeater beside the main rack.
Combo Uplink Bridges to a Fiber Core Switch Across BuildingsThe G1/SFP1 Combo port takes either an RJ45 copper run or an SFP fiber transceiver, so this rack switch can uplink over fiber to a core switch in another building while the dedicated G2 RJ45 port stays free for a local NVR or PC.
1U 19″ Chassis Fits Cleanly Beside NVRs in a Server CabinetAt 440×195×44 mm and 2.12 kg with standard 19-inch rack ears, the all-metal chassis mounts directly above or below an NVR in a server cabinet or wiring closet, drawing power from the built-in AC 100–240V supply — no external power brick to route.
Not a good fit if:
- Downlink ports are Fast Ethernet only (10/100Mbps, no Gigabit) — for 4K or multi-stream cameras that need gigabit throughput per port, choose a Gigabit PoE switch; only the two uplinks (G2, G1/SFP1) run at 1000Mbps.
- Unmanaged — no Web/CLI/SNMP access or per-port VLAN tagging; the front-panel switch offers only Default/VLAN/EXTEND positions, not granular configuration; choose a managed switch if you need remote monitoring or individual port control.
- 250 W total budget can't power all 16 ports at 30 W simultaneously (16×30 W = 480 W ≫ 250 W) — plan camera load around the 8 priority ports, and note this model is 802.3af/at only, so 802.3bt high-power PTZ domes (60–90 W) need a bt-capable switch or injector.
Key Features
- 16 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus a 1000Mbps RJ45 uplink (G2) and a 1000Mbps Combo RJ45/SFP uplink (G1/SFP1)
- 250 W total PoE budget, up to 30 W per port, IEEE 802.3af/at, Mode B pinout (4/5+, 7/8-)
- Ports 1-8 hold PoE power priority under budget contention
- Three working modes via front-panel slide switch: Default (Normal), VLAN (Secure, downlink-to-uplink only), EXTEND (250 m surveillance reach)
- VLAN (Secure) mode includes PD keepalive: automatically power-cycles an unresponsive PoE camera when it stops sending data
- IEEE 802.3x flow control, port traffic control and packet buffer optimization for smoother multi-camera streaming
- All-metal 440×195×44 mm 1U rack chassis with a single internal cooling fan, NDAA compliant

Talk to an engineer →Who uses it, where it goes and how to install it
Written for the NSW2020-16T1GT1GC-POE-IN from its own datasheet: 16 × 100 Mbps PoE ports, one 1000 Mbps RJ45 uplink plus one 1000 Mbps Combo RJ45/SFP uplink, 250 W PoE budget, 30 W per port, 1U 19-inch rack body with built-in AC power.
Who it is for
- Integrators with 9–16 camera projects — 16 PoE ports match a 16-channel NVR, and the 250 W budget is enough to give every port about 15.6 W at the same time, so a full bank of fixed cameras, or even mini PTZs, runs from one switch.
- Schools, hotels and warehouses with a server cabinet — The 1U 19-inch metal chassis with built-in AC power mounts directly above or below the NVR, with no external power brick to hide in the cabinet.
- Sites with a second building or a fibre backbone — The G1/SFP1 Combo port takes a fibre SFP module to reach a core switch or NVR beyond 100 m, while the separate G2 RJ45 Gigabit port stays free for the local NVR or a monitoring PC.
- Unattended equipment rooms — In VLAN (Secure) mode cameras can only talk to the uplinks, and PD keepalive power-cycles a camera that stops sending data, which saves a site visit for a frozen camera.
Where and how to install
- Rack position and airflow — The chassis is 440 × 195 × 44 mm (1U) and 2.12 kg. It has 1 internal fan, so keep its side vents open and leave 1U free above or below if the NVR next to it also runs hot; the operating range is 0 °C to 45 °C, and a closed cabinet in a hot room needs a cabinet fan.
- Power and UPS — Power is AC 100–240 V, 50/60 Hz straight into the switch; maximum consumption is 265 W. Size the UPS for the switch plus the NVR: a fully loaded switch alone can draw 265 W.
- NVR on an uplink port, always — Connect the NVR to G2 or G1, not to ports 1–16. In VLAN and Extend modes the datasheet says downlink ports can only talk to the uplink ports, so an NVR or PC plugged into a PoE port would no longer see the cameras.
- Cable lengths — Camera runs: 100 m normally, up to 250 m in Extend mode with solid-copper Cat5e/Cat6. Copper uplinks on G1/G2 are 100 m maximum; for anything longer use a fibre SFP module in the G1/SFP1 Combo port.
- Grounding and surge — No surge rating is listed. Bond the rack and the switch chassis to the building earth, and put Ethernet surge protectors on cable runs that come from outdoor poles or rooftops. Using fibre for links between buildings also avoids ground-potential problems on long copper.
- Plan the priority ports — Ports 1–8 keep PoE power first if demand approaches 250 W. Put entrances, cash desks and PTZs on 1–8 and less important cameras on 9–16, and label the patch panel so the next technician keeps that order.
PoE budget: how many cameras it really powers
With 250 W for 16 ports, this switch has power to spare for ordinary cameras: 16 × 6 W is only 96 W. Even 16 mini PTZs at about 13 W (208 W) fit. Power becomes the limit only with heavy PTZs: at a full 30 W per port, 8 ports use 240 W.

- Pick the NSW2020-16T1GT1GC-POE-IN for 9–16 cameras on one NVR in a rack, especially when some are mini PTZs: 16 × 13 W still fits in 250 W.
- If all 16 cameras are fixed 4 MP models (~96 W), the low-power NSW2020-16T2GC-LPOE-IN is also enough; if you need two fibre uplinks, look at the NSW2020-16T2GC-POE-IN.
- For more than 16 cameras use the 24-port NSW2020-24T1GT1GC-POE-IN instead of cascading two small switches.
Camera draws of ~6 W (4 MP IR bullet/dome), ~13 W (mini PTZ) and 25 W (larger PTZ) are typical assumptions; check the max. power on each camera's datasheet. Budget, per-port and distance figures are from the Uniview datasheet.
16-Port PoE Switch FAQ — NSW2020-16T1GT1GC-POE-IN
How many cameras can the NSW2020-16T1GT1GC-POE-IN power?
All 16 × 100 Mbps ports are IEEE 802.3af/at PoE with a 250 W total budget — about 15 W per camera with all sixteen loaded, while typical fixed IP cameras draw 4–12 W. Up to 30 W is available on a single port for PTZ or heated cameras, so a full 16-camera wall is realistic.
What uplink options does it give me?
Two gigabit uplinks: a 1000 Mbps RJ45 port (G2) plus a 1000 Mbps Combo port (G1/SFP1) that takes either copper or an SFP fiber module. That lets you run copper to a local NVR and fiber to a distant control room, or keep one uplink as a spare path.
What do the VLAN and EXTEND modes and PD keepalive do?
A front-panel slide switch picks Default, VLAN (Secure) or EXTEND. EXTEND stretches PoE runs to 250 m for far cameras. In VLAN mode, PD keepalive acts as a PoE watchdog: if a camera stops sending data for a set period, the port power-cycles it automatically — no ladder trip to reboot a frozen camera.
How is it powered and cooled in the rack?
Power is a built-in AC 100–240 V, 50/60 Hz supply — no external adapter to hide — with 265 W maximum consumption at full PoE load. One internal fan cools the 19-inch 1U chassis (440 × 195 × 44 mm, 2.12 kg), which operates 0 to 45 °C at 10–90% non-condensing humidity.
Which cameras keep power if the budget runs out, and is it NDAA compliant?
Ports 1–8 carry PoE power priority, so wire critical cameras there; the PoE-MAX indicator warns when the 250 W budget nears its limit. The switch is NDAA compliant for government-linked tenders, and its 7.2 Gbps fabric, 5.36 Mpps forwarding, 4M bit buffer and 16K MAC table handle all 16 streams plus uplinks.
Does the NSW2020-16T1GT1GC-POE-IN work with Hikvision, Dahua or other non-Uniview cameras and NVRs?
Yes. It is a plain unmanaged Ethernet switch, so any NVR brand works on the uplink, and it powers any camera that is a standard IEEE 802.3af or 802.3at PoE device, up to 30 W per port. It does not power 'passive' 12 V or 24 V PoE devices that skip standard PoE detection.
Which SFP module do I need for the G1/SFP1 port on the NSW2020-16T1GT1GC-POE-IN?
A 1000 Mbps (1000BASE-X, IEEE 802.3z) SFP module, not a 10G SFP+ module. Choose single-mode or multimode to match your fibre, and the same type and wavelength at the other end; the module, not the switch, sets the distance. The port is a Combo port, so use either the SFP or the G1 RJ45 socket, not both at once; the datasheet does not list approved module models, so tell us the other end and we will match it.
The NSW2020-16T1GT1GC-POE-IN camera ports are only 100 Mbps. Is that enough for 4K cameras?
Yes. A single 4K camera in H.265 usually streams well under 16 Mbps, so a 100 Mbps port is far from full. What matters is the sum on the uplink: 16 cameras at 16 Mbps are 256 Mbps, which is why this model uplinks at 1000 Mbps. An 8-port switch with a 100 Mbps uplink would already be overloaded by 16 cameras at 8 Mbps (128 Mbps).
I switched the NSW2020-16T1GT1GC-POE-IN to VLAN or Extend mode and my PC lost the cameras. Why?
In both of those modes ports 1–16 can only talk to the uplink ports G1 and G2, not to each other. If your PC or NVR is plugged into one of ports 1–16, move it to G1 or G2 (or to a switch behind them) and the cameras will reappear. Only Default mode lets every port talk to every other port.
What do the PoE and PoE-MAX lights on the NSW2020-16T1GT1GC-POE-IN tell me?
PoE steady on means PoE output is normal. PoE-MAX stays off below 80% of the 250 W budget and turns steady on above 85%, which is about 212 W. If PoE-MAX is lit, adding one more PTZ or a camera heater at night can exceed the budget, and the non-priority ports 9–16 are the ones at risk; move heavy loads elsewhere before that happens.
