A fiber link uses optical transmitters and receivers to move data between network devices. Its useful speed and reach depend on the entire link, including the equipment and connections.

A security fiber project needs a written boundary between cabling work, network equipment and the security application. That boundary is the basis for comparing proposals and accepting the installation.

Fiber provides a data path. Video analytics depend on camera placement, image quality, software configuration and the way people respond to events.
