Overview
The S8G02GI upgrades every access port to Gigabit, so 4K cameras, multi-sensor panoramic cameras and gigabit wireless APs each get a full-speed connection instead of sharing fast-Ethernet headroom. Two Gigabit RJ45 uplinks keep the NVR feed clean even with all 8 ports pushing high-bitrate streams at once. Built-in IEEE 802.3af/at PoE+ still delivers up to 30W per port for PTZ and IR-illuminated cameras, and the fanless metal case keeps it quiet in a rack, cabinet, or ceiling void. Choose the 96W S8G02GI for typical loads or the 120W S8G02GI, 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.
Small Hotels & GuesthousesLobby, corridors and parking under 4K cameras, all-gigabit ports keep every stream sharp.
Retail Chain StoresSales floor HD cameras plus a gigabit wireless AP for POS and inventory scanners on the same switch.
Small WarehousesDock-door 4K cameras that need full frame rate for license-plate and pallet-label reads.
Elementary SchoolsFull-gigabit campus network carrying HD classroom cameras alongside the school's own data traffic.
Clinics with Imaging EquipmentGigabit ports handle HD camera feeds alongside networked diagnostic devices without contention.
Farm Processing FacilitiesGigabit cameras on the packing line and loading area feed a local NVR without dropped frames.
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 + Gigabit Uplink — Every port keeps up with 4K cameras and gigabit wireless APs, no per-stream downgrade.
- 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 S8G02GI from its own specifications: 8 × 10/100/1000M PoE ports, 2 × gigabit RJ45 uplinks, 96 W or 120 W PoE budget, 30 W per port, fanless IP30 metal case.
Who it is for
- Shops and hotels mixing cameras and Wi-Fi — Gigabit PoE on every port powers both IP cameras and gigabit wireless access points from one switch, so a lobby or sales floor needs only one PoE switch.
- Installers using high-bitrate or multi-sensor cameras — Warehouses and docks with 4K or multi-sensor cameras: no access port is held to 100M, and the 2 gigabit uplinks carry all 8 streams to the NVR.
- Projects planned for future upgrades — Installing gigabit now means later camera or AP upgrades do not need a new switch; the 120 W version adds headroom and a hardware watchdog for PTZ or IR-heavy loads.
- 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; 40 units per carton.
Where and how to install
- Every run under 100 m — The page lists the standard 100 m per copper segment and no extend mode, so place the switch where every camera and AP cable, measured along its route, stays under 100 m. Gigabit needs all four pairs in good condition: use solid-copper Cat5e or Cat6.
- Desk, wall or ceiling void — 173 × 124 × 38 mm, 0.9 kg, desktop or wall-mount with no 19-inch rack ears; in a rack use a shelf. Silent and fanless, so it can sit in a back office or ceiling void, but IP30 means indoors or inside a sealed cabinet only.
- Ventilation — Rated -10 to +70°C, 5–95% non-condensing. With gigabit APs and cameras on the 120 W version the case runs warm: keep space above it, keep it away from lamps and hot-water pipes in a ceiling void, and vent closed cabinets.
- Uplinks and loops — Uplink 1 to the NVR, uplink 2 to the router or the next switch. There is no STP, VLAN or web interface, so never join two switches with two cables, and check that no AP mesh or extra patch lead closes a loop back to the network.
- Surge, earthing and mains — No surge rating is listed: on outdoor cameras add Ethernet surge protectors and earth the cabinet. Input is AC 100–240 V, so it runs directly on 110/127 V or 220/240 V mains. A small UPS keeps cameras, APs and the NVR up through short outages.
PoE budget: how many cameras
8 ordinary cameras use half of the 96 W budget. The budget fills up when PTZs, heavy-IR cameras or Wi-Fi access points share the switch; that is when the 120 W version is worth it. Bandwidth is not a limit here: every port and both uplinks are gigabit.
| S8G02GI · 96 W | S8G02GI · 120 W | |
|---|---|---|
| PoE ports / uplinks | 8 × 1000M PoE / 2 × 1000M RJ45 | 8 × 1000M PoE / 2 × 1000M RJ45 |
| Total PoE budget | 96 W | 120 W |
| Max. power on one port | 30 W | 30 W |
| Fixed IR cameras at 6 W each | 8 (48 W) | 8 (48 W) |
| 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: APs at 13 W + cameras at 6 W | 2 × 13 W + 6 × 6 W = 62 W | 2 × 13 W + 6 × 6 W = 62 W |
| Copper cable per port | 100 m | 100 m |
| Extend mode | — | — |
| Watchdog auto-reset | — | ✓ |
- Pick 96 W for 8 fixed cameras, or a mix like 2 APs and 6 cameras (about 62 W).
- Pick 120 W when PTZs at 30 W join the mix, or the site is unattended and needs the watchdog.
- A camera or building beyond 100 m: the S8G02G2GFI is the same gigabit layout plus 2 SFP fibre slots.
Counts assume typical draws of 6 W (fixed IR camera), 13 W (small PTZ, heavy-IR camera or a typical Wi-Fi access point); 30 W rows use the whole budget with no reserve. Check each device's own datasheet for its maximum power.
8-Port Gigabit PoE Switch FAQ — S8G02GI
How many IP cameras can the S8G02GI power?
All 8 gigabit PoE ports can power cameras at the same time. The 96W version averages 12W per port and the 120W version 15W, while a single port can deliver up to 30W under IEEE 802.3af/at — enough headroom for PTZ or IR-heavy cameras on a full 8-camera CCTV build.
What is the difference between the 96W and 120W versions?
Both versions share the same 8 gigabit PoE ports and 2 gigabit RJ45 uplinks. The standard S8G02GI has a 96W PoE budget; the high-power 120W model adds a watchdog that auto-resets the switch itself if it locks up — the standard model has no watchdog.
How far can it carry PoE and data over copper cable?
Each copper segment supports the standard 100 m limit defined by IEEE 802.3. Powered-device detection is automatic and protects non-PoE equipment plugged into the same ports, and power is injected in Mode A over the data pairs, so no separate power wiring is needed at the camera.
Why choose a gigabit PoE switch for CCTV instead of 100M?
Every access port runs at 1000 Mbps, so 4K cameras, multi-sensor panoramic cameras and gigabit wireless APs each get a full-speed link instead of sharing fast-Ethernet headroom. With 28 Gbps switching capacity, 20.832 Mpps forwarding and two gigabit uplinks, the NVR feed stays clean with all 8 ports streaming.
Which devices can the PoE ports power?
Any standard IEEE 802.3af or 802.3at powered device: mainstream IP cameras, wireless access points and video intercoms. Detection is automatic, so non-PoE gear on the same port is never damaged. Maximum output is 30W per port, drawn from the 96W or 120W total budget.
How is the S8G02GI installed and powered?
It uses a built-in DC 52V supply fed from AC mains (100–240V input). The fanless IP30 metal case measures 173 x 124 x 38 mm, mounts on a desktop or wall, runs silently from -10 to +70 degC and is rated 50,000 hours MTBF.
Does the S8G02GI have the 250 m extend mode for a far camera?
Not according to this page: it lists the standard 100 m per copper segment and no extend mode. The S802GI and S802GIGFI pages list 250 m at 10 Mbps, which is enough for one camera at a moderate bitrate. For a far camera on this switch, use fibre through the S8G02G2GFI or a small switch near the camera; if extend mode is essential, confirm with us before ordering.
Can the S8G02GI power Wi-Fi access points and cameras at the same time?
Yes, any 802.3af/at AP or camera on any port, up to 30 W each, all sharing the total budget. Assuming 13 W per AP and 6 W per camera, 2 APs plus 6 cameras use about 62 W, within the 96 W version; with a PTZ added, choose the 120 W version. APs that need more than 30 W or a different PoE type are not covered; check the AP's datasheet.
Can cameras and office PCs share the S8G02GI?
They can physically, and gigabit ports leave enough bandwidth, but the switch has no VLAN, port isolation or web management, so cameras and PCs sit on the same network. For security and to keep office traffic from disturbing recording, a common practice is to give cameras their own switch and NVR network, with only the NVR connected to the office router. If separation is required on one switch, a managed switch is the right choice.
How do I cascade several S8G02GI switches for 16 or 24 cameras?
Connect uplink 1 of the first switch to the NVR and its uplink 2 to uplink 1 of the next, in a line or tree. At 8 Mbps per camera, 24 cameras put about 192 Mbps on the first link, well inside gigabit. Use one cable between each pair of switches only; with no STP, a second cable creates a loop that stops the network.
S8G02GI or S8G02G2GFI: do I need the SFP version?
Both have 8 gigabit PoE ports, 2 gigabit RJ45 uplinks, 96 W or 120 W and 30 W per port. If the NVR, router and every camera are within 100 m of copper, the S8G02GI is enough. Choose the S8G02G2GFI, with its 2 SFP slots in a larger 240 × 150 × 44 mm case, when a building or camera group is beyond 100 m or the link runs between buildings where fibre avoids surge problems.
