After the September 11 terrorist attacks, surveillance systems have been increasingly deployed for greater security in both public and private facilities. In addition to intrusion detection, many companies use surveillance systems for remote monitoring in locations where it may be harmful for people to stay for an extended period of time. PTZ (pan, tilt, zoom) cameras provide system administrators with a key tool for controlling the focus and viewpoints of an on-site camera. System administrators can operate PTZ cameras by RS-485 signals from distances up to 1.2 kilometers away. However, copper cabling for such an application can be quite expensive and risks potential data loss from electromagnetic interference.

Optical fiber cables offer a preferable wiring option that is both immune to electromagnetic interference and capable of longer distance communication than copper wires. Moxa's TCF-142 series media converters provide an easy way to connect serial interface PTZ cameras to a fiber network, and are ideal for both standalone and distributed systems. System administrators will also require a high-density solution at the control center to save space. Moxa's NRack System can connect up to 19 converters and only requires a single power source. By converting serial data for transmission over an Ethernet network, Moxa's NPort 6650 allows system administrators to use a UTP cable to monitor and control all PTZ cameras remotely.
