In the monitoring system, optical fiber is the connection method that can provide the best bandwidth performance among all. During the process of using optical fiber transmission, image quality is only affected by three factors: the camera, the environment and the monitor. However, the optical fiber transmission system can transmit images to a long distance without distorting the signal, nor will it reduce the clarity or details of the image.

A PoE Power supply device is an electronic product based on Power over Ethernet technology, mainly used to provide power and data transmission services simultaneously for remote power-receiving devices (such as IP cameras, wireless aps, etc.) through network cables.
