704, Video Line Receiver 



 

 

The Kramer 705 is a high performance composite video to twisted pair transmitter, and the 704 is its companion unit which converts the twisted pair format back to composite video. Transmission via twisted pair cable carries video signals farther than conventional coax cable, and is lighter and significantly less expensive. A simple system consists of a 705 located at the video source, and a 704 located at the remote display device. For systems with multiple monitors, the 704 receiver has a loop out and termination switch allowing several 704 receivers to be placed on the same TP cable driven by a 705. Even at a cable length of 400 meters, the frequency response is well over 6 MHz and at shorter distances, they provide close to broadcast level performance. Recessed gain and equalization controls are provided to optimize signal levels. A 12V power supply is provided with each unit. The 705 and 704 are part of the Kramer TOOLS family of compact, high quality, and cost effective solutions for a variety of applications.

Typical Applications:

  • Remote monitoring for CCTV, medical, schools, broadcast applications.

  • Ideal for existing facilities with TP cable already installed

  • Teleconferencing in offices and hospitals using existing intercom or telephone wiring
