Passive PoE Adapter RJ45 Injector & Splitter Kit – 12–48V IP Cam
Passive PoE Adapter RJ45 Injector & Splitter Kit – 12–48V IP Cam
Power your security IP cameras over existing Ethernet cables with this Passive PoE Adapter Cable Kit. Including both an RJ45 injector and an RJ45 splitter, this 2-piece set lets you transmit power (12–48V) and data simultaneously through a single network cable — no separate power runs needed, no cluttered wiring.
Because it is a passive PoE solution, the input and output voltage remain equal, making it a straightforward, plug-and-play way to convert non-PoE devices into PoE-enabled ones. Perfect for CCTV systems, IP cameras, wireless access points, and other network devices that need both data and power delivered over one cable.
Key Features
- Passive PoE Technology: Input voltage equals output voltage (12–48V) — simple, predictable power delivery.
- RJ45 Injector + Splitter Pair: 1 pair = 2 pieces; adds PoE capability to non-PoE network devices.
- Plug-and-Play Setup: No additional software or configuration required.
- Wide Voltage Range: Supports 12V–48V to suit a variety of cameras and network equipment.
- Primary Use Case: Designed for security IP camera systems and similar networked devices.
- Durable Plastic Housing: Lightweight yet sturdy injector body for reliable everyday use.
- Available in 2 Color Options: Choose the finish that matches your setup.
What's in the Box

Frequently Asked Questions
Q: What is a passive PoE adapter and how does it differ from active PoE?
A: A passive PoE adapter delivers power over an Ethernet cable without negotiating voltage with the connected device — the input and output voltage stay the same (e.g., 12V in, 12V out). Active PoE (such as the 802.3af/at standard) negotiates voltage automatically. Passive PoE is simpler and more affordable, but you must ensure the device you're powering accepts the voltage you supply.
Q: What devices is this passive PoE RJ45 injector and splitter kit compatible with?
A: This kit is primarily designed for security IP camera systems and other network devices that operate within a 12–48V range. It is compatible with CCTV cameras, wireless access points, VoIP phones, and similar equipment that does not have built-in PoE support, allowing you to power and connect them over a single Ethernet cable.
Q: How many adapter pairs are included in this set?
A: Each order includes 4 pieces total — that's 2 pairs. Each pair consists of one RJ45 injector (adds power to the Ethernet line at the source) and one RJ45 splitter (separates power from data at the device end).
Q: Do I need any special tools or software to install this passive PoE adapter kit?
A: No. This is a completely plug-and-play accessory. Simply connect the injector to your power source and network switch, run your existing CAT5/CAT6 Ethernet cable, and attach the splitter at the device end. No drivers, software, or configuration are required.
