Active Video Balun Transmitter For UTP Transmission From 500 To 6,000 Feet
Video Transmission Solutions
Nitek : TT560
Description
The Nitek Active Transmitter Unit for Twisted Pair Video TT560 is designed for operation over Category rated cable or twisted pair communication cable and requires a Nitek active receiver unit. The TT560 unit works equally well over existing communication and computer networks or newly installed cable. A highly balanced transmitter output design assures that the system will not interfere with other equipment on the network. In addition, the transmitter is virtually impervious to ground loop and has high immunity to noise and interference. Built-in surge suppression is standard.
A dip switch on the unit provides precise adjustment of gain and frequency compensation, allowing the system to be fine-tuned to the cable.
Features
TT560 features include:
- Active electronics compensate for frequency and level loss
- Built-in protection from power surge, transients, static or other electrical interference
- High resolution color or monochrome video
- Complete immunity to ground loop; video and AC can be run in a common raceway, where allowed
- Video can be run in the same cable with telephone and computer signals
- Weatherproof design
- Easy to install
- College Campuses - using existing communication cables saves time and money
- High Rise Buildings - between floors, through punch-down blocks
- Detention Facilities - twisted pair takes less space than coax in a conduit
- High Voltage Facilities - high immunity to AC power interference
- Parking Garages- where running coax is difficult to impossible
- Remote Gates - can be run in same cable with audio and gate control
