Active Video Balun Receiver For UTP Transmission From 100 To 1,500 Feet
Video Transmission Solutions
Nitek : TR515
Description
The Niket Active Video Receiver for UTP Transmission TR 515 is designed for operation over Category twisted pair cable and requires the use of a transmitter unit. The unit works equally well over existing communication and computer networks or newly installed cable. Advanced receiver electronics provide 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 digital adjustment technology provides easy adjustment for optimum performance over the entire operating range. The TR515 wide dynamic adjustment also allows cable length to be estimated with a wide safety margin, when bidding CCTV twisted pair transmission jobs.
Features
TR515 features include:
- 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
