Overview
The NSW2020-24T2GC-LPOE-IN is an unmanaged 19-inch rack-mount Fast Ethernet PoE switch, the lower-power-budget counterpart in this 24-port dual-Combo-uplink series, 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 250 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 (265 W max). The all-metal 440×195×44 mm 1U chassis (2.14 kg) — a shallower, lighter build than the higher-budget model in this series — 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.
Right-Sized PoE Budget for Standard Fixed Cameras, Not Overpaid-For Headroom250 W spread across 24 ports averages roughly 10 W per port — plenty for the 4-9 W draw of typical fixed bullet and dome cameras (24 × 7 W ≈ 168 W stays well inside budget), so projects that don't need 25-30 W PTZ units on every port aren't paying for PoE capacity they'll never use.
A Shallower 195 mm Chassis Fits Cabinets a Full-Depth Switch Can'tAt 440 × 195 × 44 mm and 2.14 kg, this 1U unit is noticeably shallower than the higher-budget model in this series — useful for shallow wall-mount cabinets, small IDF closets or branch-office racks where a deeper chassis simply won't close the door, while still keeping the full 24-port, 19-inch-wide layout.
Two Independent Combo Uplinks Bring Fiber Flexibility to an Entry-Tier SwitchG1/SFP1 and G2/SFP2 each switch independently between RJ45 copper and SFP fiber, so a cost-conscious deployment can still run one link to the core over fiber and keep a copper path as backup — without needing to step up to a higher-PoE-budget model just to get dual Combo uplinks.
Priority Ports 1-8 Carry More Weight on a Tighter 250 W BudgetWith less headroom than the higher-budget sibling, deciding what goes on ports 1-8 matters more here — put entrances, registers or server-room cameras on those eight ports so they're served first if the other 16 ports push aggregate draw toward the ceiling.
VLAN Secure Mode + PD Keepalive for Cost-Conscious Multi-Branch RolloutsRetail chains, small branch offices or kiosks that need identical, zero-configuration switches at every site can slide this to VLAN (Secure): the 24 downlinks talk only to the uplinks, and PD keepalive auto-reboots any camera that stops responding — all without paying for a managed-switch tier.
EXTEND Mode Still Reaches a Distant Gate Camera on the Budget TierThe same front-panel switch flips to EXTEND for up to 250 m of reach on a single port, so even this lower-power model can anchor a dense indoor camera bank on ports 1-24 while a lone gate or fence-line camera runs on extended reach — no separate long-reach switch required.
Not a good fit if:
- All 24 downlink ports run Fast Ethernet only (10/100Mbps, no Gigabit) — the two Combo uplinks (G1/SFP1, G2/SFP2) are the only 1000Mbps ports on this switch, so 4K or multi-stream cameras that need per-port Gigabit throughput need a Gigabit PoE switch instead.
- Unmanaged by design — there's no Web/CLI/SNMP interface or per-port VLAN tagging; the front-panel switch only offers Default/VLAN/EXTEND positions. If a project needs remote monitoring, SNMP alerts or individual port control, look at a managed switch instead.
- The 250 W budget can't power all 24 ports at 30 W simultaneously (24 × 30 W = 720 W ≫ 250 W) — with even less headroom than the higher-budget model in this series, plan camera load carefully around the 8 priority ports and favor cameras well under 15 W; 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, and projects expecting most ports near the 30 W ceiling should choose the higher-budget sibling instead.

Talk to an engineer →Who uses it, where it goes and how to install it
Written for the NSW2020-24T2GC-LPOE-IN from its official datasheet: 24 × 100 Mbps PoE ports, 2 × 1000 Mbps Combo (RJ45/SFP) uplinks, 250 W PoE budget with 30 W per port, 250 m EXTEND mode, 1U rack chassis only 195 mm deep.
Who it is for
- Installers on 16–24 fixed-camera projects — 24 fixed bullets or domes at about 6 W each use about 144 W, well inside the 250 W budget, so you get a full 24-port rack switch without paying for the 370 W of the NSW2020-24T2GC-POE-IN.
- Retail chains and branch offices — Unmanaged, so every site gets the same switch with no configuration; the VLAN (Secure) position isolates the 24 camera ports from each other and its PD keepalive restarts a camera that stops sending data.
- Sites with shallow wall cabinets — At 440 × 195 × 44 mm and 2.14 kg it is 50 mm shallower and 0.76 kg lighter than the 245 mm, 2.90 kg NSW2020-24T2GC-POE-IN, which matters in small wall-mount racks next to the NVR.
- Projects with a fibre link to the control room — Both uplinks are 1000 Mbps Combo ports (RJ45 or SFP), so a gatehouse or remote building can reach the NVR room over fibre beyond the 100 m copper limit while the second uplink serves a local client PC or the next switch.
Where and how to install
- Rack it with room to breathe — It is a 1U 19-inch unit with one internal fan and a 0 °C to 45 °C operating range. Keep the side vents clear, leave 1U free or a vented blank above it when the NVR sits directly on top, and add a cabinet fan if the cabinet stands in the sun.
- Power, UPS and earthing — The supply is built in (AC 100–240 V, 50/60 Hz), so only a mains cord is needed. Size the UPS for up to 265 W for this switch plus the NVR, earth the chassis to the cabinet ground bar, and fit Ethernet surge protectors on camera cables that run outdoors or between buildings.
- Plan the 8 priority ports — Ports 1 to 8 keep power first when the 250 W budget is short. Put entrances, cash desks and any PTZ there, label every port, and connect the NVR or core switch to uplink G1/SFP1.
- Cable lengths — In Default mode keep each camera run within 100 m of solid-copper Cat5e or Cat6. EXTEND mode reaches up to 250 m, but the slide switch sets the whole switch, not one port, and in that mode downlink ports can only talk to the uplinks.
- Keep it dry — Operating humidity is 10% to 90% non-condensing and the chassis is not weatherproof. In an outdoor or pole cabinet use a sealed, ventilated enclosure and keep cable entries at the bottom with drip loops.
PoE budget: how many cameras
This model and the NSW2020-24T2GC-POE-IN share the same 24 + 2 port layout and 8.8 Gbps fabric; the difference is the PoE budget. 250 W is enough for 24 ordinary fixed cameras, but not for 24 mini PTZ cameras. The datasheet's PoE-MAX light turns on above 85% of the budget, so the camera counts below keep load under that line.
| NSW2020-24T2GC-LPOE-IN (this model) | NSW2020-24T2GC-POE-IN | |
|---|---|---|
| PoE ports | 24 × 100 Mbps RJ45 | 24 × 100 Mbps RJ45 |
| Uplinks | 2 × 1000 Mbps Combo (RJ45/SFP) | 2 × 1000 Mbps Combo (RJ45/SFP) |
| Total PoE budget | 250 W | 370 W |
| Max per port | 30 W (802.3af/at) | 30 W (802.3af/at) |
| PoE-MAX light on above (85%) | 212.5 W | 314.5 W |
| 4 MP IR cameras at 6 W each | 24 (144 W) | 24 (144 W) |
| Mini PTZ at 13 W each, under 85% | 16 (208 W) | 24 (312 W) |
| Switching capacity | 8.8 Gbps | 8.8 Gbps |
| Max power consumption | 265 W | 390 W |
| Depth / weight | 195 mm / 2.14 kg | 245 mm / 2.90 kg |
| Camera cable reach | 100 m; up to 250 m in EXTEND | 100 m; up to 250 m in EXTEND |
| Operating temperature | 0 °C to 45 °C | 0 °C to 45 °C |
- Pick this LPOE model when most ports feed fixed cameras: 24 at 6 W use 144 W, leaving about 68 W before the PoE-MAX light comes on.
- Pick the NSW2020-24T2GC-POE-IN when more than 16 ports carry 13 W mini PTZ or heated cameras, or you want headroom for later upgrades.
- For 25.5 W PTZ cameras the budget, not the port count, is the limit: 8 of them on ports 1 to 8 already use 204 W.
Both columns are from the official Uniview datasheets. Camera draws of 6 W (4 MP IR fixed) and 13 W (mini PTZ) are typical planning assumptions; check the max. power on each camera's own datasheet. 85% thresholds = budget × 0.85. Uplink copper runs are limited to 100 m; SFP fibre reach depends on the module you fit.
24-Port PoE Switch FAQ — NSW2020-24T2GC-LPOE-IN
How many IP cameras can the NSW2020-24T2GC-LPOE-IN power?
All 24 PoE ports can power cameras at the same time. The 250 W budget averages about 10 W per port, and typical fixed IP cameras draw 4–12 W. Any single port can deliver up to 30 W (IEEE 802.3af/at); put heavier loads such as PTZ units on priority ports 1–8.
What uplink options does this switch give me?
Two independent 1000 Mbps Combo uplinks (G1/SFP1 and G2/SFP2). Each one runs as copper RJ45 or as SFP fiber on its own, so you can build dual-link redundancy or aggregate both toward the NVR room. The 8.8 Gbps fabric and 6.55 Mpps forwarding keep 24 camera streams moving.
How far can I run a camera from this switch?
Standard runs are 100 m over network cable. Slide the front-panel switch to EXTEND mode and PoE plus data reach 250 m, which suits gate cameras or perimeter poles without mid-span extenders. The switch also supports both Mode A (1/2+, 3/6−) and Mode B (4/5+, 7/8−) pinouts.
What does VLAN mode do, and can the switch recover a frozen camera?
VLAN (Secure) mode isolates traffic for a cleaner CCTV network and enables PD keepalive: if a PoE camera stops sending data for a set period, the port automatically power-cycles it, so a hung camera comes back without a site visit. The front-panel slide switch selects Default, VLAN or EXTEND.
How is it installed and powered?
It is a 19-inch 1U rack unit, 440 × 195 × 44 mm and 2.14 kg, with a built-in AC 100–240 V 50/60 Hz supply — no external brick. Maximum draw is 265 W, one internal fan handles cooling, operating range is 0–45 °C, and the switch is NDAA compliant.
Should I buy the NSW2020-24T2GC-LPOE-IN or the NSW2020-24T2GC-POE-IN?
Add up the max. power of your cameras: if the total stays under about 212 W (85% of 250 W), the LPOE model is enough; above that, take the POE model with 370 W. Ports, uplinks, 8.8 Gbps switching and the three working modes are identical. The LPOE unit is also shallower (195 mm vs 245 mm) and draws at most 265 W from the mains instead of 390 W, which helps with UPS sizing.
Will the NSW2020-24T2GC-LPOE-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.
Are 100 Mbps camera ports enough for 4K cameras on the NSW2020-24T2GC-LPOE-IN?
For normal CCTV streams, yes: one camera's main plus sub stream is usually well under 20 Mbps, far below 100 Mbps per port. The real limit is the 1000 Mbps uplink to the NVR; for example 24 cameras at an assumed 8 Mbps each send 192 Mbps, about one fifth of it. Only cameras that must be accessed at gigabit speed per port need a gigabit PoE switch.
Can I connect both Combo uplinks of the NSW2020-24T2GC-LPOE-IN to the same core switch for redundancy?
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-LPOE-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.
What does the PoE-MAX light on the NSW2020-24T2GC-LPOE-IN tell me?
It shows how close you are to the 250 W budget: off means total PoE output is below 80% (200 W), steady on means it is above 85% (212.5 W). If it is lit after installation, especially at night when IR LEDs switch on, move some load to another switch, because at the limit only ports 1 to 8 are guaranteed power first.
