  • Video Breakout Box
  • Airtrack & Intersense
  • Lens Controller
  • Intersense-to-Airtrack Cable
  • Airtrack-to-Lens-Controller Cable
  • Previzion Basebox (“DIAL” box)
  • Lightcraft Cable Tether
  • BNC Cables
  • UPS (recommended)
  • Metric Measuring Tape
  • LTC Source (when applicable)
  • Sync Source (when applicable)
  • Proper Camera Mounts and Rails
  • HD Camera

Software Required:
