The CatLinc VID, SVID and HD extend video signal up to 365m/1200ft over standard CAT5, CAT5e or CAT6 twisted pair cable. For shorter distances (110m/350ft or less), system power may b attached to either the transmitter or receiver. For distances greater than 110/350ft, the CatLLinc transmitter and receiver must both be powered. In this case, an additional power supply must be separately ordered (part no. CatLinc PS). CatLinc uses proven technology to transmit high-resolution computer video signals over category cable. CatLinc was designed from the ground up to balance cost, image quality, and mounting options in today’s price sensitive installation environments.
