For larger spaces and low-light shooting, the cameras feature adaptive noise reduction, and up to seven can be daisy chained together, eliminating the need for multiple control cables. Thirty-two preset memories allow for pan/tilt/zoom and other settings via remote control, and up to 127 are accessible via RS-232C or RS-422. A number of digital interfaces are available, including 3G-SDI, HD-SDI, and DVI-I.
