A PoE (Power over Ethernet) switch with four ports is a network switch that has the capability to provide both data and power to connected devices over a single Ethernet cable.
These PoE switches are commonly used in security camera installations because they simplify the setup by eliminating the need for separate power cables for each connected device, such as IP cameras or access points. The power is delivered to the devices through the Ethernet cables, making installations more flexible and efficient.
Key Features
1. Four PoE Ports: The switch will have four Ethernet ports, all of which support PoE, providing both data and power to the connected devices.
2. PoE+ Support: PoE switches usually support different PoE standards, such as IEEE 802.3af (PoE) and IEEE 802.3at (PoE+). PoE+ provides higher power output per port, which is useful for certain devices with higher power requirements.
