20 PoE switch models from 4 to 24 ports — 100M and gigabit, SFP uplink options, IEEE 802.3af/at budgets from 65W to 400W. Waterproof PoE extenders, splitters and injectors from the same factory line.

Sizing tool
Pick a model, set the device count and the class from the device label. The maths uses the IEEE 802.3 PSE figures and keeps a 20% reserve, the same rule we apply when quoting.
Comfortable — 277 W spare after the 20% reserve.

Lightning test platform
Switches deliver the power, injectors add it where there is no PoE switch, splitters separate power from data at the camera end, and extenders carry both further than 100 metres. Coax converters reuse existing coaxial cable, and surge protectors sit in front of the equipment on the lines that leave the building.
4 to 24-port PoE switches, 100M and Gigabit, with SFP uplinks and IEEE 802.3af/at budgets from 65 W to 400 W.

Eight ways buyers arrive at the range: by port count, by camera load, by link speed, by uplink distance, or by how much administration the site will actually tolerate. Still deciding? The 30-question buyer FAQanswers the ones that come up most.
Gate, kiosk, small shop — three or four cameras, one uplink.
One floor or one yard, wall-mounted, SFP uplink options.
Whole building, 16+2+1 with SFP for the backhaul.
Largest single unit, rack width, two SFP slots.
Size the switch by camera watts, not by camera count.
1 Gbps on every powered port for 4K and multi-sensor.
Fibre backhaul past 100 m and between buildings.
Plug and play, no configuration, no admin overhead.
Not sure how many ports you need? Add up the device watts, keep 20% spare, and the calculator returns the models that fit.
PoE budget calculatorSFP PoE Switch Factory has designed and manufactured PoE transmission equipment since 2011: in-house SMT lines, a 120kV simulated lightning impulse test platform, and OEM/ODM production for brand owners, distributors and export companies.

A switch if the site needs several powered ports and you are installing the network anyway. An injector if the switch is already there, in service, and only one or two runs need power — replacing a configured switch for two cameras rarely pays for itself.
Fewer than the port count, usually. The budget is shared: a 24-port switch with a 400 W supply gives an average of about 16.6 W per port if every port is loaded, which covers most fixed domes but not PTZ heads at 20-25 W. Add the labels up at their peak and compare with the supply, not with the port count.
When the device has its own power inlet — a relay board, a small switch, a non-PoE camera, an access point with a barrel jack — and you want to feed it from the PoE line instead of running a second cable. Match the output voltage and current to the device label.
Check the label: most PTZ heads draw 15-25 W and need 802.3at rather than 802.3af, especially outdoors where the heater adds load. If the camera states 802.3bt or 60 W+, use a Type 3/4 supply rather than assuming at will cover it.
