Where a 4-Port Actually Wins
Four ports is not a budget compromise — it is the right answer at the far end of a fibre run, on a pole, in a lift lobby or at a gate, where you need two or three cameras powered and one uplink home.
The family has three useful shapes. S402EI and S4G02GI are the plain 52W desktop units, fast ethernet or full gigabit, for two to four cameras. S4G02GFI-SFP replaces the copper uplink with two 1000M SFP fibre ports — that is the model you put at the end of a 2 km fibre run where no copper can reach. And the DIN-rail industrial versions (ISW2000-4T2GP-POE-IN, ZJIES1000D-P-4PT1T-DC, NSW2010-6T-POE-S-IN) take 12–48 VDC in a pole box at -40 to 75 °C, which is what most roadside and solar sites actually need.
Two cautions on this size. A 52W budget is two 802.3at devices and nothing else, so a single PTZ plus one fixed camera already fills it — check the real draw before you commit. And the 250 m extend mode, present on the fast-ethernet models, halves nothing except speed: the port drops to 10 Mbps, which carries one 2 MP stream comfortably and no more. For anything beyond that distance the fibre-uplink version plus a media converter is the design that lasts.

4-Port PoE Switch FAQ
What is the minimum order quantity for PoE switches?
None for standard units — order 2–3 samples, test them on your own site, then scale by air or LCL sea freight. MOQ only applies to OEM orders with your own logo and packaging.
Can a 4-port PoE switch run a PTZ camera?
One PTZ, yes — a 25.5W 802.3at dome fits inside a 52W or 65W budget with one fixed camera beside it. Two PTZs on the same 4-port unit is asking for brownouts the first cold night when the heaters come on. If the site has two or more PTZs, move up to an 8-port 120W model; the price difference is far smaller than a second site visit.
Do you ship PoE switches to Africa and Latin America?
Yes — small orders by air courier (typically under a week), volume by LCL sea freight with mixed cartons welcome. Voltage and plug types are verified against your country before packing, and every quote includes both freight options.
How do I get wholesale prices?
Message the models (or just your camera count) on WhatsApp and a written wholesale quotation with shipping to your country comes back within 24 hours. Freight, versions and volume change the number, so a real quote beats a fake sticker price.
