Description:
Dedicated telephone line video link system for color video transmission upto distances of 10 miles (16.1 kilometers).

V-LINK is a “full motion” video transmission system designed for operation over leased local area metallic telephone circuits or twisted pair point-to-point wire. The V-Link uses a unique patented* unconditional refresh method to provide transmission of high quality color video images. This update technique is made possible by the latest in custom integrated circuitry.

The V-Link update is unaffected by scene changes, making it ideal for use in P/T/Z systems or scenes with a lot of activity. The V-Link operates as a stand-alone unit (no PC required) and integrates directly into any existing CCTV system, including a matrix, multiplexer or switcher. The system is designed to provide fast, high quality video at a low cost. The leased line circuit (type LADA) needed for a V-Link is typically the lowest cost line available from a local telephone company. The color V-Link system is capable of handling either monochrome or color video inputs. This dual mode of operation makes it possible to upgrade a system from monochrome to color.

Leased Line Operation

Operation over leased telephone lines, requires a "Conditioned, Local Area Data Circuit" LADA line ("Conditioned" means loads coils and bridge-taps should be removed), with copper continuity from end-to-end and NO voltage supply.
