Overview
The Atlas S802EI is a compact 10-port unmanaged Fast Ethernet PoE switch built for 8-camera installs. It provides 8 x 10/100M PoE ports (IEEE802.3af/at, up to 30W per port with smart powered-device detection) plus 2 x 10/100M uplink ports in a fanless IP30 metal enclosure. The base S802EI carries a 96W power budget; the S802EI steps up to 120W and adds an independent watchdog auto-reset circuit for extra-reliable operation on heavier PoE loads or unattended sites. An Extend mode stretches PoE and data reach out to 250m on any port by stepping the link rate down to 10Mbps, and store-and-forward switching with auto-negotiation and auto MDI/MDIX keeps traffic flowing without configuration. Both variants are rated -10 to +70°C for unheated equipment rooms, corridors and rooftop cabinets.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
Small store or warehouse with 8 fixed cameras covering the whole perimeter8 PoE ports match a typical full-perimeter camera count for a small site, with 2 uplinks left free for the NVR and an onward network connection.
School corridor or campus block with cameras at every classroom entranceOne switch per corridor covers up to 8 classroom-entrance cameras, keeping cabling simple and contained within a single equipment closet per floor.
Parking lot with entrance, exit and row-coverage cameras8 ports cover entrance, exit and several row-facing cameras from one cabinet, and the Extend mode option reaches cameras mounted further out along the lot.
Remote unattended site such as a gas station or farm gate relying on the watchdog auto-resetWhere no technician is on site to power-cycle a frozen switch, the S802EI's independent watchdog auto-reset recovers the unit on its own, keeping 8 cameras online.
Hotel floor covering room corridors with 8 camerasOne switch per floor handles a full corridor of 8 cameras, and the fanless design keeps it quiet enough to sit in a housekeeping closet next to guest rooms.
Farm perimeter needing both extra distance and headroom for future camerasExtend mode reaches distant perimeter points at 250m, and choosing the 120W S802EI leaves power headroom to add PTZ or IR-illuminated cameras later without swapping the switch.
Not a good fit if:
- Unmanaged Layer 2 only — no VLAN segmentation or STP/RSTP; choose a managed switch if network isolation or spanning tree is required.
- No ring/loop redundancy protocol — wire in star, tree or bus topology only; do not create physical wiring loops between ports.
- Commercial-grade -10 to +70°C housing in a compact desktop/wall-mount form factor — not rated for industrial wide-temperature extremes and not rack-mountable without accessories.
Key Features
- 8 x 10/100M PoE ports, IEEE802.3af/at, up to 30W per port with smart PD detection
- 2 x 10/100M uplink ports to NVR or router
- Two power budgets on the same 8+2 layout: 96W (S802EI) or 120W (S802EI) for heavier camera loads
- S802EI adds an independent watchdog auto-reset circuit for unattended, high-reliability sites
- Extend mode: PoE + data reach up to 250m (link rate steps down to 10Mbps)
- No extra power cable to any camera — PoE carries power and data on one cable, cutting install cost across 8 points
- Fanless metal housing — silent operation, no moving parts to fail

Custom & OEM →Who uses it, where it goes and how to install it
Written for the S802EI from its own specifications: 8 × 10/100M PoE ports, 2 × 10/100M uplinks, 96 W or 120 W PoE budget, 30 W per port, 250 m extend mode, fanless IP30 metal case.
Who it is for
- Installers on budget 8-camera jobs — Shops, small warehouses, school corridors or hotel floors with 8 ordinary 2 MP–4 MP cameras: one camera never needs more than a 100M port, so the all-Fast-Ethernet layout keeps the cost per port low.
- Unattended remote sites — Gas stations, farm gates or pump houses: order the 120 W version, which adds a hardware watchdog that resets the switch by itself if it hangs, so nobody has to drive out to power-cycle it.
- Expanding an existing 100M camera network — Where the NVR and older cameras are already Fast Ethernet, the S802EI matches that speed; the 250 m extend mode reaches one far camera without a mid-span repeater.
- Distributors and private label — Atlas factory-direct model with neutral casing ready for your logo, custom port/power options and small batches; 40 units per carton for stock orders.
Where and how to install
- Central point, all runs under 100 m — Place it where every camera is within 100 m of cable, not just 100 m in a straight line: count the rises, bends and service loops. Keep extend mode for the one outlier camera rather than designing the whole site around it.
- Closet, desk or wall — The 173 × 124 × 38 mm metal case sits on a desk or mounts on a wall; it is fanless and silent, so it can go in a housekeeping closet or back office. It is IP30, so outdoors it must be inside a weatherproof cabinet, and it is not a 19-inch rack unit.
- Leave air around it — Rated -10 to +70°C, but a fanless case cools only through its metal, so do not bury it under other equipment, in a closed ceiling void next to lamps, or in a sun-heated box; with 8 cameras on the 120 W version the case runs warm.
- Uplinks: NVR and router — Use one 100M uplink for the NVR LAN port and the other for the router or the next switch. Both uplinks are 100M, so do not route a second switch's cameras through this one to the NVR; give each switch its own path back.
- Cable, surge and mains — Use solid-copper Cat5e/Cat6, never copper-clad aluminium, especially on an extend-mode run. No surge rating is listed: add Ethernet surge protectors on outdoor pole cameras and earth the cabinet. Input is AC 100–240 V, so it runs directly on 110/127 V or 220/240 V mains.
PoE budget: how many cameras
Eight ordinary IR cameras use only half of the 96 W budget, so the 96 W version is enough for most fixed-camera jobs. The 120 W version matters when PTZs or heavy-IR cameras are in the mix, and it adds the watchdog. Bandwidth, not power, is the other limit: both uplinks are 100M.
| S802EI · 96 W | S802EI · 120 W | |
|---|---|---|
| PoE ports / uplinks | 8 × 10/100M PoE / 2 × 10/100M | 8 × 10/100M PoE / 2 × 10/100M |
| 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 example | 1 × 30 W + 7 × 6 W = 72 W | 2 × 30 W + 6 × 6 W = 96 W |
| Cameras at 8 Mbps on one 100M uplink | 8 × 8 = 64 Mbps | 8 × 8 = 64 Mbps |
| Copper cable per port | 100 m | 100 m |
| Extend mode | 250 m @ 10 Mbps | 250 m @ 10 Mbps |
| Watchdog auto-reset | — | ✓ |
- Pick 96 W for 8 fixed cameras, APs or intercoms: 8 × 6 W is 48 W.
- Pick 120 W for PTZs or heavy-IR cameras, or for an unattended site that needs the watchdog.
- High-bitrate 4K cameras or a cascaded second switch: pick the S802GI, which has the same 8 PoE ports with 2 gigabit uplinks.
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 is an assumed main-stream bitrate; check each camera's own datasheet.
8-Port PoE Switch FAQ — S802EI
How many IP cameras can the S802EI power?
All 8 PoE ports can run cameras at the same time. The 96 W base budget averages 12 W per camera and the 120 W version averages 15 W, while typical IP cameras draw 4–12 W — a full 8-camera CCTV setup fits either way. A single port delivers up to 30 W (IEEE 802.3af/at) for PTZ units.
What does the 120 W version add over the 96 W base model?
Two things: 24 W more PoE budget for heavier loads, and an independent watchdog auto-reset circuit that reboots the switch if it ever locks up — worth having on unattended sites or where the switch feeds power-hungry cameras around the clock. Ports, speeds and housing stay identical.
How far can a camera sit from the switch?
100 m on a standard link. Switch a port to Extend mode and PoE plus data reach 250 m, with that link stepping down to 10 Mbps — enough for one camera stream at a distant gate or wall. Power rides the data pairs (Mode A) under IEEE 802.3af/at.
Is it safe to mix cameras with non-PoE devices on this switch?
Yes. Smart powered-device detection checks each port and only supplies power to genuine IEEE 802.3af/at devices, so a router or PC on a PoE port is untouched. The 2 dedicated 10/100 M uplink ports connect the NVR, and reverse-polarity plus overload protection guard the whole unit.
What are the physical and environmental specs?
Fanless IP30 metal housing, 173 × 124 × 38 mm, 0.8 kg, desktop or wall mount. The built-in DC 52 V supply accepts AC 100–240 V. Operating range is −10 °C to +70 °C at 5–95 % humidity, switching capacity 2.6 Gbps with a 4K MAC table.
What do resellers get per carton?
Reference packing is 40 units per carton, packing dimensions 220 × 185 × 46 mm per unit box, 0.8 kg per unit. Each box holds the switch, a power cord, a manual, a certificate and a warranty card. Quoted MTBF is 50,000 hours — numbers you can drop straight into a distribution quote.
Is the 100M uplink on the S802EI enough for 8 cameras going to my NVR?
For typical 2 MP–4 MP cameras, yes: 8 cameras at 8 Mbps add up to about 64 Mbps, inside the 100 Mbps uplink. Eight 4K cameras at 16 Mbps would need about 128 Mbps, which does not fit; then choose the S802GI with gigabit uplinks, or lower the bitrate with H.265.
What do I give up when I turn on extend mode on the S802EI?
Speed: the port reaches 250 m but its link drops to 10 Mbps. That carries one camera with a moderate main stream, for example 4–6 Mbps in H.265, but not a high-bitrate 4K stream, and the margin for a sub-stream is small. Use it only on the port of the far camera, with good solid-copper Cat6; if the run is longer or the link drops, use fibre or a small switch near the camera instead.
Can I cascade two S802EI switches for a 16-camera system?
It works electrically, but the 100M uplink becomes the bottleneck: if switch B feeds switch A, A's link to the NVR carries 16 cameras, about 128 Mbps at 8 Mbps each. Connect each S802EI separately to the NVR or to a gigabit core switch instead, or use two S802GI with gigabit uplinks. Never connect the two switches with two cables; the switch has no STP and the loop floods the network.
Will the S802EI power Hikvision, Dahua, Uniview or other brands of camera?
Yes, any camera, AP or intercom that follows IEEE 802.3af or 802.3at, up to 30 W on a port. Power is sent in Mode A (on the data pairs), which standard PoE devices accept. Passive 24 V PoE devices are not 802.3af/at and will not be powered; because the switch is unmanaged, it does not care which NVR or app the cameras use.
S802EI, S802GI or S8G02GI: which 8-port model should I choose?
All three have 8 PoE ports, 96 W or 120 W and 30 W per port. The S802EI is all 100M, uplinks included, and suits typical cameras into a nearby NVR. The S802GI keeps 100M camera ports but adds 2 gigabit uplinks, for high-bitrate cameras or cascading. The S8G02GI is gigabit on every port, for gigabit APs or devices that really need more than 100 Mbps each.
