Nitek active UTP Receiver - TR515

Active Video Balun Receiver - Selectable Distance Settings

Model Number: TR515

  • For UTP Category Cables
  • Operates with Nitek Passive Transmitter Baluns
  • Selectable settings from 100 to 1,500 ft (450 meters)
  • Ground Loop Immunity & Surge Protection
  • Live video transmission for operation over twisted pair or Category 5 cables.

    The TR515 is designed for operation over Category 2, 3, 4 or 5 twisted pair cable and require the use of a Nitek transmitter unit. The unit works equally well over existing communication and computer network spare pairs, or new cable installations.

    Advanced receiver electronics provide complete immunity from ground loop, hum and noise to produce maximum video quality with virtually no loss. A DIP switch on the unit provides precise adjustment of gain and frequency compensation, allowing the system to be "fine-tuned" for any cable. This unique feature provides easy adjustment for optimum performance over the entire operating range and also allows cable length to be estimated with a wide safety margin, when bidding CCTV twisted pair transmission jobs.

    The TR515 includes a power supply. Complete systems including the receiver, transmitter and power supplies are available.

    • Active electronics compensate for frequency and level loss
    • Built-in protection from power surges, 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


    • Elevators - making traveling coax unnecessary
    • High Rise Buildings - between floors, through punchdown blocks
    • Detention Facilities - using existing communication wiring
    • 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

    Wire and Cable Recommendations

    Twisted Sender is recommended for use with unshielded twisted pair (UTP) wiring. The systems will operate over wire gauges from 26 AWG through 12 AWG but are optimized for 24 AWG. Category 2, 3, 4 or 5 cabl may be used.

    Individually shielded pairs should be avoided, as they drastically reduce the operating range of the systems. Multi-pair cable with an overall shield is acceptable. Video can be operated in the same communication cable coexistent with telephone, computer, control signals, power voltages and other video signals. While video may be routed through telephone punch down block terminals, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
