POEINJ4G Overview
This Gigabit midspan PoE+ injector is a cost-effective alternative to upgrading your existing network switch to a PoE-capable model.
It supplies up to 30 Watts output to each port, so you can easily power and access up to four high-power PoE-compliant devices — such as IP cameras — using standard Ethernet cable.
More power, with less cost and hassle
This versatile midspan PoE+ injector is suited for almost all PoE device classes, including wireless access points, as well as IP phones and cameras. The high-power PoE+ injector offers 120W total power distribution and delivers full power — up to 30.8W — from each port. Now, you can easily scale and power your PoE+ devices across long distances, even in remote locations where a typical power outlet is unavailable.
Plus, the cost-effective Power over Ethernet+ injector lets you connect your PoE-powered devices (PDs) to a non-PoE-capable switch, avoiding the expense and aggravation of upgrading your existing switch to a PoE-enabled model.
Easy to set up in mixed environments
This injector is the perfect solution for a variety of environments. It features a wall-mountable rugged metal casing, but is palm-sized making it perfect for desktop placement too.
With plug-and-play operation, you can enjoy fast and hassle-free setup without disrupting your workflow.
Convenient, protected connections
Not sure which class your PoE devices are? The Gigabit midspan PoE+ injector automatically detects the power requirements of your PoE PDs, and delivers the appropriate level of power without damaging your devices.
With integrated circuit protection between each port, your devices are also protected from power interference.
The POEINJ4G is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Frequently Asked Questions
Can the POEINJ4G power high-demand devices like PTZ cameras or Wi-Fi 6 access points? +
Yes, this injector supports the IEEE 802.3at (PoE+) standard, providing up to 30W of power per port. It is fully capable of handling high-draw equipment like motorized PTZ security cameras and high-performance Wi-Fi 6 access points, provided the total power budget of the unit is respected across the four ports.
Does the StarTech.com 4-Port PoE+ injector support legacy 802.3af devices? +
Absolutely. This unit is fully backwards compatible with the IEEE 802.3af standard. It automatically detects the power requirements of your connected equipment, allowing you to safely mix and match older devices with newer PoE+ hardware on the same injector without risking electrical damage to lower-power peripherals.
How does this PoE injector integrate into an existing non-PoE network switch setup? +
This device functions as a midspan injector, meaning it sits between your existing non-PoE network switch and your powered devices. You simply connect your switch to the input ports and your PoE-enabled devices to the output ports. It injects the necessary DC power onto the data cables without requiring any configuration changes to your existing network switches.
What is the maximum data throughput I can expect when using this 4-port Gigabit injector? +
The POEINJ4G features Gigabit Ethernet ports, ensuring that your network remains capable of 1000Mbps speeds. It is designed to be transparent to your network traffic, maintaining full line-rate performance for data-intensive applications like streaming surveillance footage or high-speed wireless backhaul, ensuring that the power injection process does not become a bottleneck for your data flow.
Can I mount this injector in a rack, or is it strictly a desktop device? +
The POEINJ4G features a compact, durable design suitable for both desktop placement and wall mounting. While it does not include standard rack-mount ears, its small form factor makes it ideal for deployment in IT closets, under desks, or attached to wall surfaces near the end devices that require power, providing excellent flexibility for various installation environments.
What kind of power management or monitoring features does the POEINJ4G include? +
This injector operates as a plug-and-play solution, focusing on reliability and simple deployment. It provides automatic device detection and protection features that monitor power delivery to ensure safe operation. It does not require complex software management or a web-based GUI, making it a highly reliable and efficient choice for environments where dedicated power management overhead is unnecessary.
Is this PoE+ injector compliant with Cat5e cabling? +
Yes, this unit is compatible with Cat5e cabling, which is sufficient for delivering both Gigabit data and PoE power over standard distances. For optimal performance and to minimize potential heat buildup in the cable bundles over longer runs, we always recommend using high-quality Cat6 or Cat6a cabling, especially when consistently operating at the higher 30W output limit.
Does the POEINJ4G require a software driver or special setup to function? +
No drivers or software are required. This unit is a true hardware-based plug-and-play device. Simply connect your power source, plug in your network cables, and the unit automatically handles the handshaking with your connected PoE devices. It is designed for seamless operation, allowing you to add PoE functionality to your network infrastructure in minutes without any complicated software configuration steps.
