POE stands for Power over Ethernet. A POE IP camera is a type of network camera that receives both data and power through a single Ethernet cable, without the need for a separate power supply.
POE technology allows the camera to receive power directly from the Ethernet network, which can simplify installation and reduce the need for additional cabling. POE IP cameras are typically used in situations where it may be difficult or expensive to run power cables to the camera location, such as in outdoor installations or in large buildings.
There are two types of POE IP cameras: standard POE cameras and POE+ cameras. Standard POE cameras typically require up to 15 watts of power, while POE+ cameras can require up to 30 watts of power.
POE IP cameras are compatible with POE network switches or injectors that provide power to the camera. It is important to ensure that the network switch or injector is compatible with the camera's power requirements before installing the camera.
