Furthermore, the integrated circuit prevents power interference between individual ports, significantly increasing the reliability and longevity of your connected IP Cameras and other devices. Rely on a stable and secure power supply!
Simplicity That Convinces: Plug-and-Play for Your PoE Devices
Complex installations are a thing of the past! The Extralink PoE Injector is a true Plug-and-Play marvel. Simply connect it, and it automatically detects whether a device is PoE-enabled and supplies it with the appropriate power. This not only saves you time and effort but also the costs for elaborate Cabling and additional power supplies. A cost-effective and efficient solution to future-proof your Network infrastructure.
Strengths & Notes at a Glance
- Pro: Cost-effective PoE Integration: Enables power supply for up to four PoE devices via existing Ethernet Cables, without the need to purchase an expensive PoE-enabled network switch or upgrade the entire network infrastructure.
- Pro: High Compatibility and Performance: Supports both the IEEE 802.3af and the more powerful 802.3at (PoE+) standard, delivering up to 30.8 watts per port and a total power of 120 watts, which can power a wide range of devices such as PTZ cameras and high-performance Access Points.
- Pro: Easy Installation and Flexible Placement: Thanks to Plug-and-Play functionality and a robust, wall-mountable metal housing, setup is quick and straightforward. The compact size allows for both desktop placement and discreet wall mounting in various environments.
- Note: Not optimized for very large networks: For installations with a very high number of PoE devices (e.g., more than 4), a dedicated PoE switch can be a more efficient and manageable solution, as multiple injectors can lead to cable clutter and more required power outlets.
- Note: No standby function for energy saving: The injector continues to consume power when the power supply is connected, even if no devices are active. For maximum energy saving, the power supply must be manually disconnected when not in use.

Frequently Asked Questions (FAQ)
What is a PoE Injector and what is it used for?
A PoE Injector (also called a midspan) is a device that delivers data and electrical power over a single Ethernet Cable to PoE-enabled end devices such as IP Cameras, WiFi Access Points, or VoIP phones. It is used to add PoE functionality to non-PoE-capable Network Switches without having to replace the entire network infrastructure.
What is the difference between 802.3af and 802.3at (PoE+)?
802.3af (PoE) is the original standard and delivers up to 15.4 watts per port. 802.3at (PoE+) is an evolution that provides up to 30.8 watts per port, thus capable of powering more power-intensive devices such as PTZ cameras or multi-stream Access Points. 802.3at is backward compatible with 802.3af.
Can I operate non-PoE devices with this 4-port PoE Injector?
No, the Extralink 4-Port PoE Injector is designed to deliver power to IEEE 802.3af/at compliant PoE devices. It automatically detects whether a connected device is PoE-capable and only then supplies power. Non-PoE devices would only receive data but no power supply via the Ethernet Cable.
How far can I place a PoE device from the switch using this Injector?
The maximum cable length for Ethernet Cables that transmit both data and PoE is standardly 100 meters (approx. 330 feet). This also applies to the connection via this PoE Injector.
Is this PoE Injector suitable for use in harsh environments?
The Extralink Injector features a robust metal casing and is wall-mountable, indicating a certain degree of resilience. However, for extremely harsh industrial or outdoor environments, there are special "ruggedized" or "industrial-grade" PoE Injectors / Power Supplies designed for wide temperature ranges, shock and vibration resistance, and enhanced protection against electrical interference.
Can this 4-port Injector also be used for high-power Edge-AI cameras?
The Injector supports 802.3at (PoE+) and delivers up to 30.8 watts per port, with a total power of 120 watts. While this is sufficient for many AI-enabled IP Cameras, some high-performance Edge-AI IP Cameras, especially those with GPUs or LPR modules, may require the newer 802.3bt (PoE++) standard, which can deliver up to 60W (Type 3) or 100W (Type 4) per port. It is important to check the exact power requirements of the AI IP Camera.
