A PoE injector is the answer to a specific problem: you have a camera, an access point or a door controller at the end of a cable run, and the switch it lands on has no PoE on that port. Rather than replacing the switch, an injector — a midspan — sits inline and adds power to the pair, so the device gets data from the existing switch and power from a wall socket near the rack. For a handful of cameras added to a site that was never wired for them, that is a far cheaper and far faster answer than a switch refresh.

Wattage is the decision that matters, and it is set by a standard rather than a marketing number. 802.3af (PoE) provides roughly 15.4 W at the source, 802.3at (PoE+) about 30 W, and 802.3bt (PoE++) 60 W or 90 W depending on the type — and cable losses mean the device at the far end always receives less than the injector supplies. A fixed indoor dome may sit comfortably inside 802.3af; add a heater, a blower, an illuminator, a wiper or pan-tilt-zoom motors and the same camera family jumps to 802.3at or 802.3bt. Read the camera's own maximum draw, not its idle figure, and buy the standard above it.

The rest is the site. Link speed matters where the camera is multi-gigabit or the run feeds an aggregation point — the 2.5G, 5G and 10G injectors here exist for that. Port count matters when several devices need power at one location, where a four-port or eight-port midspan is tidier than four wall warts. And where the injector will live in a soffit, a plant room, a DIN-rail cabinet or an unconditioned enclosure rather than in a comfortable rack, the industrial models with wide temperature ranges and IP-rated housings are the ones that survive. Cards carry live pricing and current availability from the catalog.

Buyer's checklist

How to choose a PoE injector

  • Start from the powered device's maximum draw, not its idle figure. A camera with a heater, blower, illuminator, wiper or pan-tilt-zoom motors draws far more when all of it is running on a cold night than it does on a bench, and that peak is the number the injector has to cover.
  • Buy by standard: 802.3af is roughly 15.4 W at the source, 802.3at about 30 W, 802.3bt 60 W or 90 W. Then allow for cable loss — the device at the far end receives less than the injector supplies, and a long run costs more of it — so leave headroom rather than sizing to the exact figure.
  • Match the link speed to the camera and the run. Gigabit is enough for the great majority of IP cameras; the 2.5G, 5G and 10G injectors here are for multi-gigabit endpoints and for aggregation points, and putting a gigabit injector in front of a multi-gigabit device caps the link at the injector.
  • Use a multi-port midspan where several devices share one location. Four-port and eight-port midspans put the power in one managed place with one power feed instead of a wall wart per camera, which is both tidier and much easier to put on a UPS.
  • Specify an industrial injector for anywhere that is not a conditioned room. Wide-temperature models rated from around -40 °C, IP30 housings and DIN-rail or wall mounting are what survive a soffit, a plant room, a gate cabinet or an outdoor enclosure; a desktop injector in that position is a callout waiting to happen.
  • Check the pinout family where equipment is older. Injectors deliver power on different pairs — the alternative A and B schemes — and while standards-compliant devices negotiate correctly, some legacy or passive equipment does not. Where a device is old or non-standard, confirm the injector's scheme against it.
  • Consider a PoE switch instead once the count grows. Injectors are the right answer for a few devices added to existing infrastructure; past roughly a handful at one location, a PoE switch is usually cheaper, easier to power-protect and easier to manage than a shelf of midspans.

Injector or PoE switch: which one the site actually needs

The honest rule is a count. If you are adding one to a few powered devices to a site whose switching is already installed and has no spare PoE, an injector is the correct and much cheaper answer: it needs no configuration, it does not touch the existing network, and it can be added the same afternoon. It is also the right answer when a single device needs more power than the installed switch can give — a 90 W 802.3bt camera or access point in front of a switch that only does 802.3at, for instance, where one injector solves it without replacing the switch.

Once the count climbs, the arithmetic reverses. Eight injectors mean eight power supplies, eight things to put on a UPS, eight things to find when one fails, and no central view of which port is delivering what. A PoE switch consolidates all of that into one managed device with one power budget and per-port control, which also means a camera can be power-cycled remotely instead of by someone walking to a soffit. The multi-port midspans on this page sit between the two: one chassis, one feed, four or eight powered ports, and no switch configuration to touch.

Wattage, cable loss and the environment

Three things cost power between the injector and the camera, and only one of them is on the datasheet. The standard sets what the source supplies — roughly 15.4 W for 802.3af, about 30 W for 802.3at, 60 W or 90 W for the 802.3bt types — and the device's rated maximum is what it wants. Between them sits the cable: resistance over a long run at a small conductor gauge turns some of that budget into heat, which is why the received power is always lower than the supplied power and why a 90-metre run to a heated camera should not be sized to the exact figure on the box. Buying the next standard up is usually cheaper than diagnosing a camera that reboots on the coldest night of the year.

The environment decides the chassis. A plastic-shell desktop injector is fine in a rack or on a shelf; it is not fine in a soffit, a gate cabinet, a plant room or an unheated roof space, which is where a great many camera injectors actually end up. The industrial models here carry wide temperature ranges, IP30 housings and DIN-rail or wall mounting for exactly that. Send us the camera model and its maximum draw, the run lengths, the count per location and where each injector will physically live, and we will come back with part numbers, availability, lead times and volume pricing — with the cameras, the NVR, the surveillance drives and the cabling on one document. Where the order carries an origin clause, request a TAA-verified quote and screening is performed before it is issued.

FAQ

Common questions

What wattage PoE injector does an IP camera need?
It depends on what the camera does when everything is running. A fixed indoor dome often sits inside 802.3af, which supplies roughly 15.4 W at the source. Add a heater, a blower, an infrared illuminator, a wiper or pan-tilt-zoom motors and the same family typically needs 802.3at at about 30 W, and the larger PTZ and multi-sensor units need 802.3bt at 60 W or 90 W. Read the camera's maximum draw rather than its idle figure, allow for the power lost in a long cable run, and buy the standard above the number rather than exactly at it.
Should I use a PoE injector or a PoE switch?
Count the devices. For one to a few powered endpoints added to a site whose switching is already installed, an injector is cheaper, needs no configuration and touches nothing else. It is also the right answer when one device needs more power than the installed switch can deliver — a 90 W camera in front of an 802.3at switch, for example. Past a handful at one location the arithmetic reverses: a PoE switch gives you one power budget, one thing to protect with a UPS, per-port control and the ability to power-cycle a camera remotely instead of climbing to it.
Does an injector reduce the maximum cable length?
It does not add length, and it consumes part of the 100-metre channel. Ethernet's 100 metres is the total run from the switch to the powered device, and the injector sits inside that budget along with its own patch leads — so the sum of switch-to-injector plus injector-to-camera has to stay within it, not each leg separately. Power behaves the same way: the longer the run after the injector, the more of the wattage is lost in the cable and the less arrives at the camera. Plan both together, and where the run is long, buy the next standard up.
Do I need an industrial PoE injector?
If the injector will live anywhere that is not a conditioned room, yes. Camera injectors very often end up in a soffit, a gate cabinet, a plant room, a roof space or an outdoor enclosure, where a plastic-shell desktop unit sees temperatures and humidity it was never specified for. The industrial models on this page carry wide operating temperature ranges from around -40 °C, IP30 housings and DIN-rail or wall mounting, which is what makes them survivable in those positions. In a rack or on a shelf indoors, a standard injector is the right and cheaper part.
Are these PoE injectors TAA compliant?
It is a per-part-number fact rather than a family rule, and this page is mixed: several units carry a TAA marking in the manufacturer's own catalog title while otherwise similar parts in the same range do not. Where our catalog data records a part number as TAA compliant, that is what we are reporting. Where an order carries a country-of-origin clause, request a TAA-verified quote and read the designation on the exact part number ordered — screening is performed before the quote and screening results are available with it, tied to that part number and never restated as a Uniqcli certification.
Can business, government and education buyers order these?
Every line Uniqcli quotes is sourced through US distribution and screened for TAA country-of-origin and NDAA §889 status before checkout — with documentation tied to the specific part number, not a product family.
