Data Transmission/Control Systems - for operation over unshielded twisted pair (UTP) wire cables and leased telephone lines. Systems designed for use over either point-to-point unshielded twisted pair wire of 18 AWG to 26 AWG or leased metallic telephone lines; can be either direct or through a Central Telephone Office. Individually shielded twisted pairs should not be used. Connections through splices and punch-down blocks are acceptable. Nitek data systems are designed to extend operation of control and signalling circuits for P/T/Z, remote equipment control and access control equipment for security applications, among other uses.
Video transmission systems for operation over leased telephone lines and unshielded twisted pair (UTP) wire cables. These systems are designed for use over leased metalic telephone lines; can be either direct or through a central telephone office. These systems operate over point-to-point unshielded twisted pair wire of 18 AWG to 26 AWG . Individually shielded twisted pairs should not be used. Connections through splices and punch-down blocks are acceptable. The systems transmit an "unconditional refresh" time-lapse video update, transmitting up to 10 miles(16.1 kilometers).
