Description:
Live video transmission for operation over twisted
pair or Category 5 cables.

Both the TR515 and TR560 are designed for operation over Category 2, 3, 4 or 5 twisted pair cable and require the use of a Nitek transmitter unit. The units work 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 and TR560 include the receiver and a power supply for the receiver. Complete systems including the receiver, transmitter and power supplies are available.

For more information refer to the Ordering Information section of this sheet or call Nitek.

Features:

• 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
  

Receiver Unit

Applications:

• 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.
