PoE Injectors

A PoE injector adds Power over Ethernet to a single Ethernet line — it sits between a standard (non-PoE) network switch and the camera, feeding PoE power into the cable while passing data through. Two common use cases: (1) adding one or two new cameras onto an existing non-PoE network without replacing the switch, and (2) extending PoE to a remote camera where running a new cable is impractical. The two spec decisions: PoE tier (802.3af for standard fixed cameras, PoE+ 802.3at for PTZ, 4K and high-power models) and port count (single-port per camera, or multi-port 4/8/16 for several cameras off one injector).

Security Cameras Australia stocks PoE injectors across Hikvision, HiLook, StarTech and other brands. Every unit is genuine Australian stock with full manufacturer warranty.

For systems with 4+ cameras, a dedicated PoE switch is usually the cleaner answer than per-camera injectors. For runs beyond 100 metres, see PoE extenders.

Key features of PoE injectors

  • PoE tier — 802.3af (15.4 W per port) for standard fixed cameras at 6–10 W; PoE+ 802.3at (30 W per port) for PTZ, 4K AcuSense / ColorVu, and high-power models at 15–25 W.
  • Single-port or multi-port — single-port per camera (typical desktop or wall-mount); multi-port (4, 8, 16) for several cameras off one injector chassis.
  • Gigabit Ethernet pass-through — full 1 Gbps data on the line, no bottleneck for 4K streams.
  • Mains-powered — the injector connects to a standard 230 V AC outlet for its power source.
  • Compact — single-port units are typically the size of a small power brick; multi-port models in 1U rack form factor.

When to use a PoE injector vs a PoE switch

Injector when: retrofitting one or two cameras onto an existing non-PoE network; adding a remote camera onto an existing data switch where a dedicated PoE switch is overkill; running a single camera at distance from a non-PoE source.

Switch when: the install is 4+ cameras (per-camera injectors get expensive fast); the install benefits from managed-switch features like VLAN segregation; you want one device managing all cameras rather than multiple injectors. See network switches.

How to spec a PoE injector

  • Confirm the camera's power requirement — if it's a PTZ, 4K AcuSense or ColorVu, you typically need PoE+ (802.3at), not standard PoE.
  • For a single camera, choose a single-port injector. For 4 cameras, a 4-port chassis is usually cheaper than four single-port injectors and simpler to mount.
  • Verify gigabit Ethernet pass-through — older 100 Mbps injectors exist but are inadequate for 4K streams.
  • Consider the install location — the injector needs mains power, so it sits near an outlet (typically in a comms cabinet, under a desk, or in a small wall-mount enclosure).

Frequently Asked Questions about PoE Injectors

When should I use a PoE injector instead of a PoE switch?

Use an injector for 1–2 cameras being added onto an existing non-PoE network, or for a single remote camera at distance from a non-PoE source. Use a PoE switch for 4+ cameras — per-camera injectors get expensive fast at scale, and a switch is cleaner architecture for multi-camera installs. The break-even is typically around 3–4 cameras.

Can a single PoE injector power multiple cameras?

Single-port injectors power one camera. Multi-port injectors (typically 4, 8 or 16 ports) power multiple cameras from one chassis. Multi-port injectors are essentially mid-tier between a single injector and a PoE switch — they include the PoE power across all ports but lack the network-management features of a full managed switch.

Will an injector power my PTZ or 4K camera?

Only if it's PoE+ rated (802.3at, 30 W per port). Standard PoE injectors (802.3af, 15.4 W per port) are insufficient for PTZ, 4K AcuSense, ColorVu, and other high-power models that draw 15–25 W. Confirm the camera's spec and match the injector's tier accordingly.

How is a PoE injector installed?

PoE injectors connect between your network source (existing data switch or NVR LAN port) and the camera. The injector itself needs a 230 V AC outlet for its power source. Run an Ethernet cable from the data switch to the injector's "data in" port, then run another Ethernet cable from the injector's "PoE out" port to the camera. No configuration required — plug and play.

What's the maximum cable distance from a PoE injector to the camera?

100 metres on Cat6, same as a PoE switch — the limit is set by Cat6 cable physics, not by the injector. The Ethernet run from the data switch to the injector itself doesn't count toward this limit (it's data only, no power), but the PoE-powered run from injector to camera does. For runs beyond 100 m, use a PoE extender mid-cable.
