Overview
The S8G02G2GFI/GFID is the full-gigabit flagship of the 8-port line: 8 Gigabit PoE ports paired with 2 Gigabit RJ45 uplinks and 2 Gigabit SFP slots, so a project with high-bitrate 4K cameras and a fiber backbone can use both at once. Run the RJ45 uplinks to a nearby switch and the SFP ports to two separate fiber runs for path redundancy, or split camera traffic across copper and fiber to keep any single link from getting overloaded. Every PoE port still delivers up to 30W under IEEE 802.3af/at, and the fanless metal case keeps it silent under load. Choose the 96W S8G02G2GFI for typical loads or the 120W S8G02G2GFI, which adds a watchdog auto-reset, for heavier PTZ/IR loads.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
Multi-Story GuesthousesFiber riser between floors on the SFP ports, ground-floor lobby cameras on the RJ45 uplink.
Farms with Several BuildingsHouse, barn and storage shed each on their own fiber run into the two SFP ports for a redundant path back to the office.
Construction Site Command CentersTemporary office linked to two separate site trailers over fiber, cameras on gate and material yard on copper.
Small School Campuses (Two Blocks)Fiber uplinks connect the classroom block and the admin block back to a shared NVR closet.
Gas Stations with a Car Wash BayFiber uplink to the wash bay switch, copper uplink handles the main forecourt cameras.
Small Clinic Outbuilding ClustersFiber connects a detached ward or lab building back to the main NVR room over two redundant SFP paths.
Not a good fit if:
- Not a managed switch -- no VLAN segmentation, spanning-tree, or web management interface. Choose a managed model if the project needs VLANs or loop-prevention protocols.
- No ring-network redundancy protocol -- built for star, tree, and bus topologies, not self-healing ring recovery.
- Commercial -10°C to +70°C rated in a desktop/wall-mount metal case without 19-inch rack ears -- not for extreme industrial wide-temperature sites or standard 19-inch rack rows.
Key Features
- IEEE 802.3af/at PoE+, 30W per Port — Delivers up to 30W on every port -- runs PTZ domes, IR-illuminated cameras, and PoE access points with no separate injector.
- Smart Powered-Device Detection — Identifies a genuine PD before energizing the port, so a miswired cable or non-PoE device won't get fried and idle ports don't waste power.
- All-Gigabit Access + RJ45/Dual SFP Uplink — Run copper and fiber together, or split traffic across two paths for extra uplink headroom.
- Gigabit to Every Camera — Full 1000M on all PoE ports, so 4K and multi-sensor units keep their frame rate instead of dropping to 100M.
- One Cable for Power and Data — No separate power run to pull -- camera power and video ride the same Cat5e/6 cable, cutting cable cost and install labor on every point.
- Fanless, Silent, Maintenance-Free — Sealed metal enclosure with zero moving parts -- silent, dust-tolerant, and maintenance-free tucked in a back office, ceiling void, or equipment cabinet.
- 96W or 120W, Watchdog on the High-Power Version — Available in 96W and 120W PoE power budgets, with the 120W version adding a watchdog auto-reset for heavier PTZ/IR loads -- pick the version that matches the job.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the S8G02G2GFI from its own specifications: 8 × 10/100/1000M PoE ports, 2 × gigabit RJ45 uplinks, 2 × gigabit SFP slots, 96 W or 120 W PoE budget, 30 W per port, fanless IP30 metal case.
Who it is for
- Small campuses with two or three buildings — Schools, clinics or farms: the switch sits in the NVR room, powers up to 8 local cameras, and takes one fibre from each of two outbuildings into its 2 SFP slots.
- Multi-floor guesthouses and hotels — Fibre riser on one SFP to an upper floor, the other SFP to an annex, and gigabit PoE ports for cameras and gigabit Wi-Fi access points on the same switch.
- Projects with high-bandwidth devices — Every PoE port is gigabit, so multi-sensor cameras, gigabit APs or other devices that need more than 100 Mbps each are not limited by the access port.
- Distributors and private label — Atlas factory-direct model: neutral casing ready for your logo, custom port/power options, chipset options on a project basis and small batches; 20 units per carton.
Where and how to install
- As the hub in the NVR room — A common layout: RJ45 uplink 1 to the NVR, uplink 2 to the router, SFP 1 and SFP 2 to two different remote buildings, 8 PoE ports for the cameras around the main building, each within 100 m.
- Bigger case, plan the space — At 240 × 150 × 44 mm and 1.1 kg it is larger than the other 8-port models; desktop or wall-mount, no 19-inch rack ears, so use a shelf in a rack. Leave room beside it for a fibre termination box and two LC patch leads.
- Ventilation — Fanless and rated -10 to +70°C, 5–95% non-condensing. The metal case is the heatsink, so keep space above it, do not stack equipment on it, and ventilate closed cabinets, especially with the 120 W version near full load.
- Copper runs: 100 m, no extend mode — The page lists the standard 100 m per copper segment and no 250 m extend mode, so a camera farther away needs fibre to a small switch near it. Use solid-copper Cat5e or Cat6 for gigabit ports.
- Surge, earthing and mains — Fibre between buildings carries no surge; outdoor copper camera runs still need Ethernet surge protectors and an earthed cabinet, since no surge rating is listed. Input is AC 100–240 V, so it runs directly on 110/127 V or 220/240 V mains, and put the hub on a UPS.
PoE budget: how many cameras
Power works exactly as on the other 8-port models: 8 ordinary cameras use half of the 96 W, and PTZs or heavy-IR cameras call for the 120 W version. Bandwidth is not the issue here: even 8 local cameras plus 16 more behind the two fibres, at 8 Mbps each, are about 192 Mbps on the uplink to the NVR.

| Small PTZ / heavy-IR cameras at 13 W, keeping 20% reserve | 5 (65 W) | 7 (91 W) |
| 30 W devices at full load | 3 (90 W) | 4 (120 W) |
| Mixed example | 1 × 30 W + 7 × 6 W = 72 W | 2 × 30 W + 6 × 6 W = 96 W |

| Watchdog auto-reset | — | ✓ |
- Pick 96 W for 8 fixed cameras or APs: 8 × 6 W is 48 W.
- Pick 120 W when 2 PTZs at 30 W share the switch, or the hub must recover by itself with the watchdog.
- Only one fibre link and ordinary cameras: the S802GIGFI (100M PoE ports, 1 SFP) is enough.
Camera counts assume typical draws of 6 W (fixed IR camera) and 13 W (small PTZ or heavy-IR camera); 30 W rows use the whole budget with no reserve. 8 Mbps per camera is an assumption; fibre distance depends on the SFP module.
8-Port Gigabit PoE Switch FAQ — S8G02G2GFI
How many cameras can the S8G02G2GFI power, including 4K models?
All 8 gigabit PoE ports power devices simultaneously under IEEE 802.3af/at. The 120W version averages 15W per port; typical IP cameras draw 4–12W, so 8 cameras fit comfortably. Each camera also gets a full gigabit link, which suits high-bitrate 4K streams, and a single port can supply 30W.
Why does it have two SFP slots?
The 2×1000Base-X SFP slots allow dual fiber uplinks: run two separate fiber paths for redundancy, or split camera traffic between copper and fiber so no single link is overloaded. The 2 gigabit RJ45 uplinks stay available for a nearby switch or NVR at the same time.
How far can each camera cable run?
Each copper segment follows the IEEE 802.3 limit of 100m from switch port to camera. For links beyond that, or between buildings, use the 1000Base-X SFP slots with fiber modules on the uplink side instead of stretching copper past specification.
What is the difference between the 96W and 120W versions?
Both share the same layout: 8 gigabit PoE ports, 2 gigabit RJ45 uplinks, 2 SFP slots, 30W max per port. The 96W standard model has no watchdog; the 120W high-power model raises the PoE budget and adds a watchdog that auto-resets the switch itself if it locks up, without a site visit.
What devices is it compatible with?
Any device that follows IEEE 802.3af/at: mainstream IP cameras, wireless APs and video intercoms. Detection is automatic — the switch verifies the powered-device signature before applying voltage, so non-PoE equipment on the same ports simply gets a data connection without risk.
How is it installed and powered?
The fanless metal housing measures 240×150×44mm, is IP30 rated and sits on a desktop or mounts to a wall. A built-in DC 52V supply runs from AC 100–240V input, over an operating range of -10°C to +70°C.
Can I connect both SFP ports of the S8G02G2GFI to the same core switch as a backup link?
No. The switch is unmanaged with no STP or ring protocol, so two links between the same two points form a loop that floods the network and stops the cameras. Use the two SFP ports for two different directions, for example one fibre to each outbuilding, in a star or tree. If you need a true backup path, that requires a managed switch with STP or ring support at both ends.
Which SFP modules do I need for the S8G02G2GFI?
1000M (1000Base-X) SFP modules, one per fibre link, matched to the module at the other end: same fibre type (multimode or single-mode), compatible wavelength, and an A/B pair if you use single-fibre BiDi modules. The page does not list modules or reach for this model, so send us each link's distance and fibre type and we will quote matching pairs. Remote ends can be our S4G02GFI-SFP or S802GIGFI, which also take 1000M SFP modules.
Does the S8G02G2GFI have the 250 m extend mode of the S802GI family?
Not according to this page: it lists the standard 100 m per copper segment and no extend mode, while the S802GI and S802GIGFI pages do list 250 m at 10 Mbps. For a camera beyond 100 m from this switch, run fibre from one SFP slot to a small switch near the camera, or confirm with us before ordering if extend mode is essential.
Do I need the gigabit camera ports of the S8G02G2GFI for 4K cameras?
Usually not: a typical 4K camera streams around 8–16 Mbps, which a 100M port carries easily, so the S802GIGFI also works for 4K. The gigabit ports matter for gigabit Wi-Fi APs, multi-sensor cameras with high combined bitrates, or other devices that need more than 100 Mbps each, and they leave room for future upgrades. Choose this model mainly for the second SFP slot and those gigabit devices.
How much traffic can the S8G02G2GFI handle as a fibre hub for two remote buildings?
Each SFP link is 1000M and the RJ45 uplink to the NVR is also 1000M. With 8 cameras behind each remote fibre and 8 local cameras at 8 Mbps each, the NVR link carries about 192 Mbps, far below gigabit. In practice the NVR's own incoming bandwidth limit is reached long before this switch's links, so check the NVR's specification.
