PoE Splitter 48V to 12V – IP Camera Ethernet Power Module

Standard PoE Splitter 48V to 12V – IP Camera Ethernet Power Supply Module

Power your IP cameras cleanly and efficiently with this Standard PoE Splitter. It takes 802.3af/at Power over Ethernet (PoE) input at 48V and converts it to a stable 12V DC output, eliminating the need for a separate power adapter at the camera end. Simply plug into your PoE switch or injector, run a single Ethernet cable, and your IP camera is powered and connected — no extra wiring required.

Whether you are expanding a home surveillance setup, deploying cameras in a warehouse, or upgrading an existing IP network, this compact module delivers reliable performance in a plug-and-play form factor.

Frequently Asked Questions

Q: What does a PoE splitter do and how does the 48V to 12V PoE splitter work?

A: A PoE (Power over Ethernet) splitter receives power and data combined over a single Ethernet cable from a PoE switch or injector, then separates them — delivering the data signal via its pass-through Ethernet port and converting the 48V PoE power down to 12V DC output for your IP camera or other 12V device. This means you only need one cable run to both connect and power your camera.

Q: Is this PoE splitter compatible with my IP camera?

A: This splitter outputs 12V DC and is compatible with most standard IP security cameras that require a 12V power input. It is designed to work with IEEE 802.3af and 802.3at PoE switches and injectors. Always check your camera's power requirements before installation to confirm 12V compatibility.

Q: Do I need a special PoE switch to use this splitter?

A: You need a PoE-capable switch or PoE injector that supports the IEEE 802.3af or 802.3at standard. Standard (non-PoE) switches will not supply the power needed. If your switch is not PoE-enabled, a separate PoE injector can be added to your network run.

Q: Can I use this PoE splitter outdoors?

A: This module is designed for use in dry or sheltered installations. If mounting near an outdoor camera, place the splitter inside a weatherproof junction box or enclosure to protect it from moisture and the elements.
