Webcam connected to optical fiber

The optical fiber turns around, reaches the camera point, cuts and fuses the tail fiber, and connects to the optical fiber transceiver.

Of course, the network camera is connected to the optical fiber transceiver through the network cable, and the four network cables of the four optical fiber transceivers in the monitoring room are directly connected to the switch and NVR.

The second scheme is also possible, but it feels relatively troublesome. Anyway, it is the easiest to melt fiber wherever you go.
