The lens wizard and focus aid make lens adjustment easy and straightforward, and ensure proper focus throughout the 24-hour cycle.  All cameras can operate on both AC and DC.  LineLock and phase adjustment are available, when AC power is used.  NightSense, available in FlexiDome color versions, is a feature that can extend its excellent sensitivity by a factor of three in monochrome operation.  All cameras incorporate Bilinx, a technology that allows technicians to set up and control the camera settings remotely over the video cable.
