The Poe to 12V splitter is a specialized device that plays a vital role in powering non - Poe devices that require a 12V DC power input. It is designed to work in tandem with Poe - enabled devices such as Poe injectors, multi - port Poe midspans, or Poe switches.

　　In scenarios where an IP camera, for example, requires 12V DC power but does not support native Poe, the Poe to 12V splitter becomes an essential component. Instead of running a separate power cable to the camera's location, which can be challenging, especially in hard - to - reach areas, a single Cat - 5 or higher - grade Ethernet cable can be used. The Poe to 12V splitter takes in the combined data and power signal (usually 48V DC in a standard Poe setup) through its Poe input port (RJ - 45). It then splits this signal into two parts: a 12V DC output for powering the non - Poe device and an Ethernet data output for network connectivity.

　　These splitters are often compliant with IEEE 802.3at and 802.3af Ethernet standards, which means they can work with a wide range of Poe - enabled devices. When used with an IEEE 802.3at Ethernet source, they can typically provide a maximum output power of 30 watts, while with an IEEE 802.3af source, the maximum output power is 15.4 watts. The 12V DC output is provided through a dedicated connector, which is then connected to the power input of the non - Poe device. The Ethernet data output is connected to the network port of the device, such as an IP camera.

　　Many Poe to 12V splitters also support Gigabit Ethernet speeds (1000 Mbps), allowing for high - speed data transfer. This is important for devices that need to transmit large amounts of data, like high - resolution IP cameras. They also support Cat - 5e cables up to 100 meters, providing flexibility in terms of installation distance. Some models of Poe to 12V splitters are designed to be compact and lightweight, making them easy to install in tight spaces. They may also come with additional features such as LED indicators to show the power status and data transfer activity, as well as protection mechanisms against short circuits and over - voltage situations to ensure the safety of the connected devices.
