There are many high-end security cameras out there that still shoot in the standard composite video. Thor's line of F-SEC fiber transmitters is designed to extend the life of this equipment.Thor's fiber optic security transmitters still use the same high-end 10-bit digital encoding that our broadcast transmitters use, just in a less expensive chassis. They offer many different configurations and services with this line of products. In addition to video, we can also carry data, Ethernet, telephone, or audio in the same unit. Speak with a sales representative today to discuss specific options and pricing. Thor's units come with standard single-mode optics with a transmitting distance of up to 20 km.
