POE Splitter 48V to 12V Isolated Ethernet RJ45 IP Camera Power

The POE Splitter 48V to 12V Isolation Ethernet RJ45 Port is a compact, plug-and-play power solution designed to bring both data and power over a single network cable — then split them cleanly to devices that don't natively support Power over Ethernet (PoE). Whether you're powering IP cameras, wireless access points, or other 12V network devices, this splitter makes integration straightforward and cable-clutter-free.

Why Choose This POE Splitter?

• 48V to 12V Isolated Output: Safely converts 48V PoE input down to a stable 12V DC output, with galvanic isolation for added circuit protection.
• Single-Cable Simplicity: Receives both power and data over one standard Ethernet cable, then separates them — data passes through the RJ45 port, power outputs via DC connector.
• Broad Compatibility: Works with IP security cameras, surveillance systems, wireless access points, and other 12V non-PoE devices.
• Plug-and-Play Setup: No additional configuration or software required — simply connect and go.
• Durable ABS Housing: Constructed from robust ABS material, built to withstand everyday use in both indoor and light outdoor network installations.
• Compact Form Factor: Small and unobtrusive — ideal for discreet installation at camera or device mounting points.

How It Works

A PoE switch or injector sends 48V power along with data through a standard Cat5e/Cat6 Ethernet cable. The POE Splitter receives the combined signal at its input RJ45 port, isolates the power from the data, converts the voltage to 12V DC, and delivers each separately — data through the output RJ45 port and power through the DC output jack. This means your non-PoE camera or device gets clean, stable power without any rewiring.

Frequently Asked Questions

Q: What does a POE Splitter 48V to 12V do and how does it work?

A: A PoE splitter receives a combined power-and-data signal (48V) from a PoE switch or injector over a single Ethernet cable. It then separates the power from the data signal, converts the 48V down to a stable 12V DC output, and delivers each independently — so you can power 12V devices like IP cameras without needing a separate power cable or a PoE-enabled device.

Q: Which devices is this POE Splitter compatible with?

A: This splitter is compatible with any 12V device that connects via Ethernet, including IP security cameras, CCTV cameras, wireless access points, and other non-PoE network devices. It works with standard IEEE 802.3af/at PoE switches and injectors that output 48V.

Q: Is the POE Splitter easy to install?

A: Yes — it is completely plug-and-play. Simply connect your PoE-enabled Ethernet cable to the input RJ45 port, plug the 12V DC output into your camera or device, and connect the data pass-through RJ45 to your device's network port. No software, drivers, or additional configuration is needed.

Q: What is the difference between an isolated and non-isolated POE Splitter?

A: An isolated PoE splitter (like this one) uses galvanic isolation to electrically separate the input and output circuits. This provides an additional layer of protection against voltage spikes, ground loops, and electrical interference — making it a safer and more reliable choice, especially for sensitive equipment like IP cameras in outdoor or mixed-voltage environments.
