Nitek four channel modular active video receiver card

Model Number: TR560x4

  • Unshielded Twisted Pair (UTP) transmission up to 3,000 feet (900 meters) up to 6,000 feet (1,800 meters) with active transmitters
  • Unit for Modular Twisted Pair Video System

The TR560x4 modular card is designed for use with the modular rack system. The system holds up to ten (10) modular cards, in any combination, using the RK400 card cage (not included). This modular plug-in feature allows the system to be custom configured for each application and provides easy expandability.

The TR560x4 is designed for operation over category 2, 3, 4 or 5 twisted pair cable. The system works equally well over existing communication and computer network spare pairs or new cable installations. A highly balanced transmitter output design assures that the system will not interfere with other equipment on the network. Advanced receiver electronics provide complete immunity from ground loop, hum and noise to produce maximum video quality with minimum loss.

A DIP switch on the receiver unit provides incremental adjustment of gain and frequency compensation to allow the system to be fine-tuned for an existing cable. This unique feature provides adjustment for optimum performance over the entire operating range and also allows cable length to be estimated with a wide safety margin. The TR560x4 includes only the receiver card.

  • 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 code allows
  • Video detect LEDs for each receiver
  • RJ45 or push terminals for easy connection


  • Intra-building CCTV installations (instead of coaxial cable)
  • Structured cabling (Category 5) environments
  • To eliminate requirement for Plenum Coax
  • Multi-camera applications through conduit (more cameras through a smaller diameter)

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 cable 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.
