Overview
The NSW2020-24T2GC-POE-IN is an unmanaged 19-inch rack-mount Fast Ethernet PoE switch with 24 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus two independent 1000Mbps Combo RJ45/SFP uplinks (G1/SFP1, G2/SFP2), each able to switch on its own between copper and fiber for dual-link redundancy or aggregation. It delivers a 370 W total PoE budget (30 W max per port, IEEE 802.3af/at, Mode A and Mode B pinout) over an 8.8 Gbps switching fabric with 6.55 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 (390 W max). The all-metal 440×245×44 mm 1U chassis (2.90 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.
Two Independent Combo Uplinks for Dual-Link Redundancy or AggregationG1/SFP1 and G2/SFP2 each switch independently between RJ45 copper and SFP fiber, so you can run one link to a primary core switch and a second as a backup path — or point both toward the same core for extra uplink throughput — without adding a second switch or a media converter.
24-Port PoE Bank Still Fits a Full 24-Channel NVR in One 1U Switch24 individually-fed 100Mbps PoE ports mean a single 1U switch can power and cable an entire 24-camera deployment — useful for parking structures, retail chains or warehouse perimeters where a second switch would eat rack space and add another point of failure.
A 370 W Pool Comfortably Feeds a Realistic 24-Camera DeploymentMost installations mix a few 25–30 W PTZ or IR bullet cameras with a larger group of sub-10 W fixed cameras — under that realistic load, 370 W across 24 ports rarely gets tight; only plan around the 8 priority ports if every port might approach the 30 W ceiling at once (see Not a Good Fit below).
Priority Ports 1-8 Keep Your Most Important Cameras Powered FirstWhen aggregate PoE demand climbs toward the 370 W ceiling across 24 competing ports, ports 1-8 are served first — wire entrances, loading docks or server-room cameras there so those feeds are the last to lose power under load.
VLAN Secure Mode with PD Keepalive Fits Unattended Multi-Site RolloutsSlide the front-panel switch to VLAN (Secure) and all 24 downlink ports can reach only the uplinks; PD keepalive then auto-reboots any camera that stops sending data, cutting truck rolls as the number of remote sites and cameras per site both grow.
EXTEND Mode Still Reaches a 250 m Perimeter Camera Alongside the Dense BankThe same slide switch flips to EXTEND (surveillance mode) for up to 250 m of reach on a single port, so this 24-port switch can anchor a dense indoor camera bank and a distant gate or fence-line camera at the same time, all from one 440×245×44 mm 1U chassis (2.90 kg).
Not a good fit if:
- All 24 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 Combo uplinks (G1/SFP1, G2/SFP2) 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 across a large camera bank.
- 370 W total budget can't power all 24 ports at 30 W simultaneously (24×30 W = 720 W ≫ 370 W) — plan camera load around the 8 priority ports; this model is 802.3af/at only (Mode A/B), so 802.3bt high-power PTZ domes (60–90 W) need a bt-capable switch or injector.

Talk to an engineer →Who uses it, where it goes and how to install it
Written for the NSW2020-24T2GC-POE-IN from its official datasheet: 24 × 100 Mbps PoE ports, 2 × 1000 Mbps Combo (RJ45/SFP) uplinks, 370 W PoE budget with 30 W per port, 250 m EXTEND mode, 1U rack chassis 245 mm deep.
Who it is for
- Projects that mix PTZ and fixed cameras — Parking lots, yards and warehouse perimeters: 8 PTZ cameras at 25.5 W on ports 1 to 8 plus 16 fixed cameras at 6 W total about 300 W, still under 85% of the 370 W budget.
- Installers building 24-channel systems — One 1U switch powers a full 24-camera NVR, and 24 mini PTZ or heater cameras at 13 W (312 W) still fit, which the 250 W NSW2020-24T2GC-LPOE-IN cannot do.
- Multi-site operators — No configuration on site: slide to VLAN (Secure) to keep the 24 camera ports isolated from each other, with PD keepalive restarting any camera that stops sending data.
- Sites with a fibre backbone — Two 1000 Mbps Combo uplinks (RJ45 or SFP) let a remote building reach the control room over fibre, beyond the 100 m copper limit, without a separate media converter.
Where and how to install
- Check cabinet depth first — The chassis is 440 × 245 × 44 mm and 2.90 kg, 50 mm deeper than the LPOE version. Measure the usable depth of a wall cabinet before ordering and leave room behind for the power cord; use rack ears and, in a deep floor rack, a shelf or rear support.
- Ventilation at high load — With up to 390 W drawn from the mains, a heavily loaded unit warms the cabinet more than the LPOE model. Keep the side vents clear, do not stack the NVR directly on top, and stay inside 0 °C to 45 °C; add a cabinet fan or air conditioning in hot equipment rooms.
- Power, earthing and surge — The AC 100–240 V, 50/60 Hz supply is built in. Earth the chassis to the cabinet ground bar and fit Ethernet surge protectors on PTZ and pole-camera cables that run outdoors, since those are the runs most exposed to lightning.
- Port plan — Wire PTZ cameras and key entrances to ports 1 to 8, which keep power first when the budget runs short. Connect G1/SFP1 to the NVR or core switch and keep G2/SFP2 for the next switch or a viewing PC.
- Cable runs — Keep camera runs within 100 m of solid-copper Cat5e or Cat6 in Default mode; for a camera 100 to 250 m away, EXTEND mode covers it but changes the whole switch. Use fibre on an uplink for anything farther.
PoE budget: how many cameras
370 W is the point of this model: it covers loads that the 250 W LPOE version cannot. The per-port limit is still 30 W, so the total budget, not the 24 ports, decides how many PTZ cameras you can add. Counts below keep the load under 85% (314.5 W), the level at which the PoE-MAX light turns on. The NSW2020-24T1GT1GC-POE-IN column shows the sibling with the same budget but one fixed RJ45 uplink plus one Combo uplink.

- Pick this model when more than 16 ports carry 13 W cameras, or when you need several 25.5 W PTZ cameras on the same switch as a full fixed-camera bank.
- Pick it over the NSW2020-24T1GT1GC-POE-IN when you want fibre on both uplinks, for example one fibre to the control room and one to a second building.
- If all your cameras are ordinary fixed models at about 6 W, the 250 W NSW2020-24T2GC-LPOE-IN is enough.
Both columns are from the official Uniview datasheets. Camera draws of 6 W (4 MP IR fixed), 13 W (mini PTZ) and 25.5 W (PTZ) are planning assumptions; use the max. power on each camera's datasheet, including IR and heater at night. 85% = budget × 0.85. Uplink copper runs are limited to 100 m; SFP fibre reach depends on the module.
24-Port PoE Switch FAQ — NSW2020-24T2GC-POE-IN
Can the NSW2020-24T2GC-POE-IN run 24 cameras at full load?
Yes — all 24 PoE ports at once. The 370 W budget averages about 15 W per port, while typical IP cameras draw 4–12 W, so a full 24-camera wall including several PTZ units is realistic. Each port supplies up to 30 W under IEEE 802.3af/at; give demanding devices priority ports 1–8.
What is the difference between the POE-IN and LPOE-IN versions?
Switching hardware is shared: 24 × 100 Mbps PoE ports, dual gigabit Combo uplinks, 8.8 Gbps fabric, 16K MAC table. This POE-IN version carries a 370 W PoE budget (390 W max draw, 440 × 245 × 44 mm, 2.90 kg); the LPOE-IN version offers 250 W for lighter loads. Choose by the total wattage your cameras need.
Can I uplink over fiber and copper at the same time?
Yes. G1/SFP1 and G2/SFP2 are two independent 1000 Mbps Combo uplinks; each selects copper RJ45 or SFP fiber on its own. Run one fiber link to the control room and keep a copper link as backup, or aggregate both. The 8.8 Gbps fabric with 6.55 Mpps forwarding handles full 24-port traffic.
What is the maximum cable distance for PoE cameras?
100 m in Default mode, per the Ethernet standard. Flip the front-panel slide switch to EXTEND and PoE power plus data reach 250 m for far gates or perimeter poles. Both Mode A (1/2+, 3/6−) and Mode B (4/5+, 7/8−) power pinouts are supported, easing compatibility with mixed camera brands.
Can it auto-restart a camera that stops responding?
Yes. In VLAN (Secure) mode the PD keepalive function watches each PoE port: if a camera sends no data for a set period, the port power-cycles it automatically. Combined with the built-in AC 100–240 V supply, single-fan cooling, 0–45 °C operating range and NDAA compliance, it suits unattended CCTV sites.
What size UPS do I need for the NSW2020-24T2GC-POE-IN?
Plan for the switch's maximum of 390 W plus your NVR and any monitor on the same UPS, then choose battery capacity for the runtime you need. At a lighter real load, for example 24 cameras at 6 W (144 W of PoE), the switch draws much less, so runtime is longer than the 390 W worst case suggests. Without a UPS, every camera goes dark the moment mains power drops, because the cameras are powered by this switch.
Will the NSW2020-24T2GC-POE-IN power cameras from other brands?
Yes, if the camera is a standard IEEE 802.3af or 802.3at PoE device: the switch follows both standards and supports Mode A and Mode B pinouts, up to 30 W per port. It will not power passive 24 V or 48 V PoE devices that do not negotiate, and it cannot supply 802.3bt (60 W or 90 W) PTZ cameras. Video goes to whatever NVR you connect, because the switch only passes Ethernet traffic.
Can I point both uplinks of the NSW2020-24T2GC-POE-IN at the same core switch for more bandwidth?
Do not do this unless we confirm it for your setup. The official datasheet does not list spanning tree (STP/RSTP) or link aggregation, so two cables from this unmanaged switch into the same network can form a loop that floods it. Use G1/SFP1 to the NVR or core switch and G2/SFP2 to cascade the next switch or to a local viewing PC.
Which SFP module fits the NSW2020-24T2GC-POE-IN uplinks?
A 1000 Mbps (1000Base-X, IEEE 802.3z) SFP module; 10G SFP+ modules will not run in these ports. Choose single-mode or multi-mode to match your fibre, use the same type at both ends (or a matched BiDi pair), and pick the module's reach to suit the distance. The datasheet does not publish a compatible-module list, so ask us to quote the module together with the switch.
If I set the NSW2020-24T2GC-POE-IN to EXTEND for one far camera, what changes for the other ports?
The front-panel switch sets the mode for the whole unit, not one port. In EXTEND all downlink ports can reach up to 250 m, but they can only talk to the uplinks, so a PC or second NVR plugged into a downlink port will not see the cameras, and extended-reach links normally run at a reduced speed. If only one camera is far away, a cleaner option is fibre or a separate small switch near that camera.
