SDI (Serial Data Interface) is the newest surveillance camera technology to arrive in the CCTV world! This interface allows for fast, uncompressed raw HD data to flow from the newest devices over a standard coaxial cable. Let your clients upgrade to amazing quality 1080p, 720p and other HD formats without spending additional funds to replace their fully functional COAX-based wiring network. Why fix it or replace it if isn''t broke? That''s a question face every day by users who are looking to add higher resolution cameras to their existing networks. Many consider IP camera technology too expensive to purchase, install and maintain. HD CCTV technology is the logical alternative. There''s no learning curve - SDI cameras operate exactly the same as standard technology cameras from the user''s standpoint, and they install into any surveillance network with coax cabless. Help your clients avoid the pain of IP-based network and show them the easy alternative. They''ll be happy to move to HD-SDI!
