This is VISCA network, but it was modified to remove many of the limitations that hinder other cameras. Most PTZ cameras were built for framing only and don't have the resolution or level of control for cinematic camera motion that can add so much production value to a shoot.  eMotimo ST4 was built for cinematic motion.  In our implementation of VISCA, instead of a total of 8 variable speeds of zoom, we have 128 speeds.  Instead of 24 pans and 20 Tilt speeds, we have 128.  The ST4 actually has over 100K different speeds possible that it automatically traverses when accelerating and decelerating, but 128 feels nice an stepless for most live moves.  Most commands modified to enable finer and position accurate control at levels previously possible.  Additionally, we are bringing the the ability to easily add linear motion from sliders and dollys.
