PoE Switch for IP Cameras

Quick answer

The right PoE switch for an IP camera system is chosen by watts, not by ports. Add up the draw on the camera labels at peak — a fixed dome is about 6 W, an 802.3af device 15.4 W, a PTZ head 25 W — keep 20% spare, then pick the smallest switch whose budget covers the total. Ports are the ceiling; the budget is the limit you actually hit.

A camera network fails at the power supply far more often than at the port count. The camera labels are printed in watts and the switch is sold in ports, so the two numbers get compared in the wrong order — then the first cold night with heaters and IR on takes the far end of the site down.

The 20 models here are the same platform described by port count: 4 to 24 powered ports, 65–400 W budgets, 100M and gigabit access, with copper or SFP uplinks. Which one fits your site depends on how many cameras you have and what each one draws.

How to choose

  • Start from the camera labels, not the camera count. Read the watts on each camera or its datasheet: a 1080p fixed dome is usually 4–8 W, a PTZ with IR and heater 20–30 W. Sum them at peak, add 20%, and that is the switch budget you need.
  • Then the port count. Powered ports must be at least the number of cameras; leave one or two spare for a camera added later rather than buying a second switch.
  • 100M or gigabit. One 4 Mbps stream per port does not need gigabit on the access side. It matters where a port carries a multi-sensor camera, and it matters at the uplink, where all the streams add up.
  • Distance decides the uplink. Interior runs under 100 m are copper; buildings linked with an existing fibre backbone use the SFP slot so the camera traffic does not cross a copper link between buildings.

How many devices will each model actually power?

Calculated from the published budget of each model with a 20% reserve kept for PoE start-up surge, IR load at night and ageing. The figure is capped by the powered-port count, so it never promises more devices than there are ports. Budgets are pooled — one 25 W PTZ takes what several 6 W domes would.

CCTV PoE switch: what changes when the whole site is cameras

A camera site is the easiest PoE load to size, because almost every device is powered from the switch and the loads are stable — but it is also the least forgiving, because a camera that drops power is a camera that stops recording, and nobody notices until the footage is needed.

Three things separate a CCTV PoE switch from one powering access points or phones. The night load is higher than the day load, because IR illuminators switch on. The cameras are spread over long cable runs, so the far end of a run sees more voltage drop than the near end. And the whole site is often on one switch, so one power supply sizing mistake affects every camera at once.

  • Size on the night load. IR and heaters are on when the site is quiet and nobody is watching the power meter. A switch that is comfortable at noon can refuse power at 19:00.
  • Keep the spare ports powered. A spare port is only useful if the budget still has room for the camera that will go on it.
  • Watch the uplink after NVR playback. Live streams are a light load; several operators pulling recorded footage is what saturates a 100M uplink.
  • Protect the outdoor runs. A camera on a pole is the tallest thing on most sites, and the cable back to the switch is the path a surge takes indoors. See the surge protector range.

How many cameras will each switch power?

The table in this section of the page is the short answer: for each model, the number of cameras it can power at four typical draws, with 20% reserve kept. The arithmetic is deliberately conservative — it never promises more devices than the unit has powered ports.

Where a site mixes device types, run the sum rather than the table: four PTZ heads at 25 W plus eight domes at 6 W is 148 W, which needs a 200 W budget with the reserve kept, and leaves five powered ports free on a 16-port unit.

For a site you are quoting now, put the numbers into the PoE budget calculator — it returns the models that cover the load with the reserve intact, and you can send the result straight to us as an RFQ.

Choosing between 4, 8, 16 and 24 ports for cameras

Port count follows the camera count, with one or two spare. The smaller units are wall-mounted and fanless, which suits a shop, a gate or a single floor; the 16- and 24-port units are cabinet or rack hardware for a whole building.

The awkward size is 12 cameras: a 16-port unit leaves four spares and costs less than two 8-port units, but it puts all twelve cameras on one power supply. Where the site cannot tolerate that, two 8-port units in different cabinets is the usual compromise.

Frequently asked

What PoE switch do I need for 8 IP cameras?

An 8-port PoE switch with a 120 W budget covers eight fixed domes with plenty in hand (8 × 6 W = 48 W). If some of the eight are PTZ heads, the sum climbs to 150–200 W and you should move to a 16-port unit with a larger budget rather than run an 8-port unit at its ceiling.

How many watts does an IP camera need?

Read the label or the datasheet: fixed domes are commonly 4–8 W, PTZ cameras with IR and heater 20–30 W, and multi-sensor or 4K models with active cooling can sit above 30 W. The IEEE classes cap what a port must supply (15.4 W for af, 30 W for at, 60 W for bt), not what the camera uses.

Do I need a gigabit PoE switch for IP cameras?

Not for the camera ports in most cases — a 4 Mbps 1080p stream does not fill a 100M port. Gigabit matters at the uplink once several streams share it, and for 4K or multi-sensor cameras. The gigabit range lists the models with gigabit access ports.

Can a PoE switch power a non-PoE camera?

Not directly. A non-PoE camera needs its own supply, or a PoE splitter between the cable and the camera, which takes the 48 V PoE feed and outputs the DC voltage the camera expects. See the PoE splitter range for the voltage options.

What is the best PoE switch for CCTV?

The one whose budget covers the night load of your camera list with 20% spare and whose ports cover the count plus one or two spares. For most 8–16 camera sites that is an 8- or 16-port unit with SFP uplink; there is no single best model without the camera list.

Can the camera cable run more than 100 metres?

Not from the switch port — 100 m is the Ethernet channel limit and PoE does not extend it. A PoE extender repeats data and power mid-span, or IP-over-coax converters reuse existing coax runs at up to 2 km.

Do IP cameras need a PoE switch or can they use injectors?

Injectors are the cheap fix when an existing non-PoE switch is already installed and only one or two cameras need power. For a new installation with several cameras, a PoE switch is one device, one cable per camera and one thing to troubleshoot. The comparison is in injector vs switch.

What happens if the cameras draw more than the switch budget?

The switch refuses power at start-up for the last devices in its priority order, or drops them under load. On a camera site that usually appears at dusk, when IR and heaters come on — cameras that worked all afternoon reboot in a loop. Size to the sum of the labels at peak.
