Transmission distance and quality of coax will determine the performance of the surveillance system. a&s goes beyond the camera and takes a peek at where back end products currently stands.
A major advantages of HD-SDI technology is the existing infrastructure which could potentially be reused. The coax can still be kept in place, which saves time and cost of installation. However, HD-SDI solution will not work with “just any” coaxial cable. Since HD-SDI is digital, it does not degrade like analog does, according to Todd Rockoff, Executive Director, HDcctv Alliance. Installers bidding retrofits will need field testers to verify the status of the cables.
