Split camera

Set a Gigabit switch in the computer room, and connect it to point A (with Gigabit switch) with optical fiber+optical fiber transceiver. Here, all network cameras are connected into a LAN and a tree-structured network by using optical fibers or switches.

The wiring of network camera is the same as that of pan/tilt camera, and 485 has integrated network transmission function.

Computer room switches and convergence switches need all Gigabit enterprises. After all, it needs a transmission speed of about 60M/S, and 100 megabit is not enough.

If only there were more than five types of network cables.

There is another way to use a wireless microwave bridge. The overall architecture is similar, but the optical fiber is replaced by wireless.

But the use of wireless requires

1? Wireless points are visible.

2? Need some professional knowledge to construct.
