Overview

S16G02GI is Atlas's all-gigabit 16-port PoE switch: 16 auto-sensing 802.3af/at Gigabit PoE ports, 2 Gigabit RJ45 uplinks, and 2 Gigabit SFP slots for fiber redundancy or backhaul, all within a 200W power budget. What sets it apart from the rest of the Atlas PoE line is a one-key port isolation / VLAN mode: switch it on and every PoE port can talk only to the uplink, never to another PoE port, which stops a broadcast or loop storm from one bad camera or miswired patch cable from ever reaching the rest of the network -- a common cause of choppy, freezing video on installer jobs.

Is This the Right Fit?

Six real deployment scenarios matched to this model's actual datasheet specifications.

Multi-Floor Hotels & ApartmentsIsolate each floor's cameras from one another so a single faulty camera or cabling loop can't storm the whole building's video feed.

Schools & Campus NetworksDozens of classroom and corridor cameras on one switch; port isolation keeps a student-facing AP or a miswired patch cable from taking down the whole segment.

Office Buildings & Business Park CCTVMany cameras installed independently by different contractors over time; port isolation contains any single misconfigured device.

Mid-Size Warehouses & Logistics YardsDense camera counts and frequent re-cabling raise storm risk; one-key isolation is a fast safety net without a managed-switch learning curve.

Parking Structures & Community Perimeter MonitoringIsolates each pole camera so cable damage or moisture ingress on one run doesn't cascade into flickering video elsewhere.

Retail Chain Head OfficesStore IT staff without networking training get storm protection out of the box, no VLAN configuration required.

Not a good fit if:

Fixed-mode isolation, not full VLAN management -- the one-key mode isolates all PoE ports from each other on an all-or-nothing basis; it does not provide per-port VLAN tagging, spanning-tree, or a web management GUI. Choose a managed switch if the project needs granular VLANs or SNMP.
No ring-network redundancy protocol -- built for star, tree, and bus topologies, not self-healing ring recovery.
-10°C to +70°C is a commercial temperature range, not an industrial wide-temperature rating -- for extreme outdoor cabinets, look at Atlas's industrial DIN-rail line instead.

Key Features

All-Gigabit Access — All 16 access ports run at full 10/100/1000M, so 4K/8MP cameras and Wi-Fi 6 APs never get bottlenecked at the edge the way they would on a 100M port.
One-Key Port Isolation / VLAN Mode — Unique to this model: one switch flip isolates every PoE port from every other PoE port -- devices can only reach the uplink, not each other -- stopping broadcast and loop storms without touching a VLAN config screen.
200W PoE Budget, 30W per Port — Automatic 802.3af/at detection across all 16 gigabit ports, sized for a full run of 16 PTZ or IR cameras.
Dual Uplink Path: Copper + Fiber — 2 Gigabit RJ45 plus 2 Gigabit SFP give a choice of copper or fiber backhaul, or a primary/backup pair to the NVR room.
Fanless, Watchdog-Protected — Fanless metal enclosure with automatic watchdog reset, built to run silently and unattended in a comms closet for years.
No Field Power Run Needed — PoE delivers power and data over the same Cat5e/6 cable, cutting installer labor on every camera drop.
Desktop or Rack-Mount Enclosure — Available in desktop or rack-mount enclosures to match whatever cabinet the installation site already has.

Who uses it, where it goes and how to install it

Written for the Atlas S16G02GI from its own specifications: 16 × Gigabit PoE ports (802.3af/at), 200 W budget with up to 30 W per port, 2 × Gigabit RJ45 + 2 × Gigabit SFP uplinks, one-key port isolation, fanless, -10 °C to +70 °C.

Who it is for

16-camera projects with 4K cameras or Wi-Fi APs — All 16 PoE ports run at 10/100/1000 Mbps, so gigabit access points and high-bitrate cameras are not held to 100 Mbps at the port; 200 W runs 16 fixed cameras at a typical 6 W (96 W) with room for a few APs.
Installers on shared or messy networks — With one-key isolation on, each PoE port can reach only the uplinks, so a faulty camera, a looped patch cable or a guest device on one port does not flood the other ports. No VLAN screens to configure.
Sites that need a fibre link to the control room — Two 1000Base-X SFP slots let the switch sit in a remote building or on another floor and send all 16 cameras back over fibre, beyond the 100 m copper limit.
Distributors and brands wanting private label — An Atlas factory-direct model: neutral casing ready for your logo, custom port/power options, small batches, and chipset options on a project basis. 12 units per carton (reference) for stock planning.

Where and how to install

Indoor cabinet, shelf or wall, with air around it — The unit is 300 × 175 × 46 mm and 2.1 kg, fanless, IP30, rated -10 °C to +70 °C and 5–95% RH without condensation. Mount it indoors on a shelf, wall or in a comms cabinet, not on top of a hot NVR, and leave a few centimetres free on each side so the metal case can shed heat.
Mains power: AC 100–240 V — The power supply is built in (DC 52 V 3.85 A) and the input is AC 100–240 V, so it runs directly on 110–127 V or 220–240 V mains with no transformer. Size the UPS for up to 200 W of PoE plus the NVR and router.
Camera cables: 100 m maximum — No extend mode is listed for this model, so plan every camera within 100 m of Cat5e/Cat6, the Ethernet limit. Use solid pure-copper cable; copper-clad aluminium drops voltage on PoE. For cameras farther away, put a second switch near them and link it back by fibre.
Put the NVR on an uplink port — Connect the NVR, router or core switch to a Gigabit RJ45 uplink (copper up to 100 m) or an SFP slot. This matters with isolation on: a PoE port can then talk only to the uplinks, so an NVR or PC plugged into a PoE port would not see the cameras.
Earthing, surge and loops — No surge rating is listed for the ports: fit Ethernet surge protectors on cables that run outdoors, earth the cabinet and use the earthed plug of the supplied power cord. The switch has no spanning-tree, so never connect two of its uplinks to the same network at once.

PoE budget: how many cameras

The 200 W total, not the 30 W per port, sets the limit: 200 W over 16 ports is 12.5 W per port on average. All 16 fixed cameras fit easily; large PTZ cameras top out at about 8. The S1602G1GFI has the same budget with 100 Mbps ports and extend mode; the S24G02G2GFI is the 24-port gigabit rack model with 260 W.

	S16G02GI (this page)	S1602G1GFI	S24G02G2GFI
PoE ports / uplinks	16 + 2 RJ45 + 2 SFP	16 + 2 RJ45 + 1 SFP	24 + 2 RJ45 + 2 SFP
Access port speed	10/100/1000 Mbps	10/100 Mbps	10/100/1000 Mbps
PoE budget / max per port	200 W / 30 W	200 W / 30 W	260 W / 30 W
4 MP IR cameras at 6 W	16 (96 W)	16 (96 W)	24 (144 W)
Mini PTZ at 13 W	15 (195 W)	15 (195 W)	20 (260 W)
IR PTZ at 25 W	8 (200 W)	8 (200 W)	10 (250 W)

Mounting	Desktop or wall	Desktop, wall or 19" rack	19" rack

Ordinary 2–8 MP cameras only: the S1602G1GFI with 100 Mbps ports is enough and adds 250 m extend mode; pick the S16G02GI when you also run gigabit APs or want port isolation.
Up to 8 PTZ at 25 W, or a mix such as 4 PTZ at 25 W plus 12 fixed cameras at 6 W (172 W): the S16G02GI fits.
More than 16 devices, or a 19-inch rack only: move to the S24G02G2GFI (24 gigabit ports, 260 W).

Camera draws (6 W, 13 W, 25 W) are typical assumptions, not page figures: add up the maximum power from each camera's datasheet, since IR, heaters and PTZ motors raise the draw. Sibling figures come from their own pages on this site.

16-Port Gigabit PoE Switch FAQ — S16G02GI

How many cameras or access points can the S16G02GI feed?

All 16 gigabit PoE ports at once. The 200 W budget averages 12.5 W per port — typical IP cameras draw 4–12 W — with up to 30 W available on any single port (IEEE 802.3af/at) for PTZ cameras or Wi-Fi access points. Smart detection keeps non-PoE devices safe on the same ports.

What does the one-key port isolation actually solve?

Flip it on and every PoE port can talk only to the uplink, never to another PoE port. A broadcast or loop storm from one faulty camera or a miswired patch cable stays trapped on its own port instead of flooding the network — a common cause of choppy, freezing video on installer jobs.

Is the bandwidth really enough for 16 gigabit ports?

Yes: switching capacity is 48 Gbps with a 35.712 Mpps forwarding rate and store-and-forward switching, so all 16 gigabit PoE ports plus the uplinks can carry traffic simultaneously. The 8K MAC table covers camera fleets and office gear alike; flow control follows IEEE 802.3x.

What are my uplink options toward the head-end?

Two gigabit RJ45 uplinks plus two 1000Base-X SFP slots. That allows a fiber backhaul with a second fiber for redundancy, or fiber plus copper mixed. Star, tree and bus topologies are supported, and auto MDI/MDI-X with auto-negotiation removes cable-order worries during installation.

Can it survive a hot, dusty equipment cabinet?

It is built for that: fanless metal housing rated IP30, operating range −10 °C to +70 °C, humidity 5–95 % non-condensing, and a watchdog that auto-resets the switch on lock-up. The 300 × 175 × 46 mm unit mounts on a desktop or wall, runs a built-in DC 52 V 3.85 A supply, and lists a 50,000-hour MTBF.

Can all 16 ports of the S16G02GI deliver 30 W at the same time?

No. 30 W is the per-port maximum, but the total budget is 200 W, and 16 × 30 W would be 480 W. In practice that means 6 devices at a full 30 W (180 W), 8 PTZ at 25 W (200 W), or all 16 ports at an average of 12.5 W. Add up the maximum draw from each camera's datasheet and keep some headroom for IR and heaters at night.

Does the S16G02GI have a 250 m extend mode for distant cameras?

No extend mode is listed for the S16G02GI, so plan on the normal 100 m Ethernet limit per camera. For one or two cameras beyond 100 m, the S1602G1GFI offers 250 m extend mode at 10 Mbps; for a group of distant cameras, put a small switch near them, such as the S4G02GFI-SFP, and run fibre back to one of the S16G02GI's SFP slots.

Where do I connect the NVR on the S16G02GI when port isolation is switched on?

On one of the 2 Gigabit RJ45 uplinks or an SFP slot, never on a PoE port. With isolation on, every PoE port can reach only the uplinks, so cameras still reach an NVR on the uplink but not an NVR, PC or second switch plugged into another PoE port. If the job needs devices on PoE ports to talk to each other, switch isolation off.

Will the S16G02GI power cameras from Hikvision, Dahua, Uniview or other brands?

Yes, any camera, AP or phone that takes standard IEEE 802.3af or 802.3at PoE, whatever the brand. The switch detects the device before powering it and uses Mode A (power on the data pairs), and a non-PoE device on a PoE port is not harmed. Passive 12 V or 24 V PoE devices and 802.3bt devices above 30 W are not supported.

Which SFP modules fit the S16G02GI, and can I use both SFP slots for a backup link?

Use 1000 Mbps (1000Base-X) SFP modules, single-mode or multimode to suit the fibre, with a matching module at the far end; no modules are listed in the box contents, so order them separately or ask us to quote them. The page lists no spanning-tree or link aggregation, so two live links to the same network would form a loop: run one link and keep the second fibre and slot as a spare you patch in if the first fails.

Can the S16G02GI be supplied with our own logo?

Yes. As an Atlas factory-direct switch it comes in a neutral casing ready for your logo, with custom port/power options and small batches welcome, and chipset options on a project basis. Printed boxes or custom packaging are not described on the page, so send us your logo, quantities and packaging needs and we confirm them in the quotation.
