Closed-circuit TV (CCTV) systems use coaxial cable, wireless technology and fiber-optic cable to transport the cameras’ signals to the monitor. Fiber-optic cable is a good choice when there is a high likelihood of off-air interference such as power lines or nearby Radio Frequency (RF) transmitters. Fiber-optic cable is also the solution for very long CCTV transmission links of more than 300 feet. Fiber-optic cable also can improve reliability and reduce maintenance costs. CCTV cameras and monitors are typically looking for RF signals, so in order to use fiber-optic (light frequency) signals, your CCTV system must have fiber-optic cable and connectors, a fiber-optic transmitter and a matching receiver. The transmitter and receiver also converts the normal RF signals to light frequency signals to give your camera and monitor the signals they need to operate. Writer Bio
