PTZ Extreme is engineered with expansion and flexibility in mind. On the left side you will find a professional grade zoom rocker and thumb roller in machined aluminum. On the right side you get a world class Hall Effect joystick for precision movement. PTZ Extreme has a size large enough to leave you hand rest for hours of operation. The lower 12 keys are usually mapped to destination selection (camera) and all knobs and buttons beyond that are equipped with crisp OLED displays so their function and value will adapt to any day at work. This controller is designed for new ways of working with eMotimo spectrum ST4 with slider and follow focus.
