The Vicon Active Crown is a purpose-built camera tracking solution designed for the demands of modern virtual production — delivering precise, reliable, real-time tracking for cameras operating on LED volume and In-Camera Visual Effects (ICVFX) stages.

• The Problem It Solves — Occlusion on ICVFX Stages : Virtual production stages are complex, electromagnetically demanding environments. Passive marker crowns frequently suffer from occlusion as cameras move, rotate, and reposition across wide LED volumes — leading to tracking dropout, rotational noise, and lost shots. Active Crown transforms unreliable tracking into dependable motion data by minimising interference, giving virtual production professionals flexible, reliable tracking for cameras positioned anywhere on ICVFX stages. 
• Magnetic Stalk System — Reconfigure in Seconds : Detachable magnetic stalks save time on recalibration and allow for a customised stalk layout for any capture scene, designed and tested to prevent self-occlusion. The magnetic snap connection means production crews can adapt their crown configuration between setups in seconds — no tools, no recalibration delay, no downtime.
• Active LED Markers — Superior Visibility from Every Angle : Stalks and markers are designed and tested for maximum visibility from multiple camera angles, avoiding occlusion issues. Accurate high-power LEDs and optimum placement deliver reliable tracking and visibility with IR sensors — even in the electronically complex, brightly lit environment of a large-format LED volume.
• Real-Time Shōgun Live Integration — Into Your Pipeline, Instantly : Active Crown with Shōgun Live lets studios experiment with ambitious multi-camera shoots, with high-performance motion tracking and data control through your favourite mocap software. Live positional data feeds directly into the virtual production pipeline in real time — enabling accurate LED wall rendering frame by frame as cameras move.
• Multi-Camera Support Across the Full Stage : Active Crown supports tracking of multiple cameras across the same studio set — making it scalable for productions operating two, three, or more camera units simultaneously on a shared ICVFX stage.
• Stage-Grade Durability, Vicon-Grade Reliability : A structured design that will withstand the most challenging stage environment. Active Crown is engineered to perform across full production schedules — not just demos. Designed to work seamlessly within Vicon's ecosystem and established motion capture pipelines, it benefits from world-class software and tracking algorithms.
