Kramer 711N Composite Video & Stereo Audio over Twisted Pair Transmitter (up to 400m)

Product Description

Composite Video & Stereo Audio over Twisted Pair Transmitter

The 711N is a twisted pair transmitter for composite video and unbalanced stereo audio signals. The 711N transmitter converts composite video and stereo audio to a twisted pair signal and the 712N receiver converts the twisted pair signal back into composite video and stereo audio signals.

• Bandwidth — 85MHz — 3dB.
• Twisted Pair Input/Outputs — RJ–45 connectors.
• Looping Input — 712N (RJ–45).
• Selectable Input Signal Termination — 712N.
• Level (Gain) and EQ (Peaking) Controls — 712N.
• Power Connect™ System — A single connection to the transmitter or the receiver powers both units when the devices are within 150ft (50m) of each other.
• System Range — Up to 400m (1200ft).
• Cable — UTP (unshielded twisted pair) or STP (shielded twisted pair) such as CAT 5.

APPLICATIONS

• Remote monitoring for CCTV, medical, school and broadcast applications.
• Existing facilities with TP cable already installed.
• Teleconferencing in offices and hospitals using existing intercom or telephone wiring
