Network monitoring camera, from the computer room 150 meters to 300 meters, optical fiber connection. Does every camera need an optical fiber to reach the computer room?

Not necessarily. It depends on whether your network surveillance camera is concentrated.

If concentrated, you can choose150m as the point, and one optical fiber can reach the computer room. Others will be scattered at this point, and there should be a switch machine.

If you don't concentrate, you can also choose several points to do it together and then disperse.
