Long Range Performance
Slimxx120 cameras offer OptiTrack's longest camera-to-marker range for Active markers. OptiTrack accuracy with more range enables huge tracking volumes for a wider variety of training and simulation scenarios, extreme ground or aerial robotic facilities, larger cinematic virtual production studios.

Small footprint, lightweight.
The Slimx 120’s shallow profile, light weight and invisible IR illumination are perfect for applications which require a discreet tracking system such as location-based virtual reality and cinematic virtual production .
12 megapixel sensor
Primex 120 helps you track smaller markers—closer together and at longer range—without sacrificing performance.


“Fast glass” lens
We custom design ultra–low distortion “fast glass” lenses for optimal tracking. The Slimx 120’s 12 mm lens features a wide-band anti-reflective coating for greater light transmission, larger volumes, and more precise 3D data.
Need a wider view? The Slimx 120 is also available with a 65° × 51° 18 mm wide-view lens—delivering broader coverage with fewer cameras.
On-camera status indicator
Slimx cameras can keep users informed with definable color LED indicator rings surrounding the lens. Recording a performance? Everyone on set knows the system is recording. Select a camera? It instantly changes color. Have your own idea? Simple software controls help you make it so.

High frame-rate capture
The Slimx 120's 300 FPS capture rate and image stopping global shutter can be used when your application requires precision for movement speeds above 150mph.
Industry-Leading Precision
Our 3D precision is the best in the business, outperforming even the highest-resolution competition—which is why Activision selected OptiTrack to build the largest and most accurate performance capture stage in existence.

Powerful on-board image processing
All OptiTrack cameras feature integrated image processing. The algorithms which identify markers and marker centers, and the sequence of data delivery are important steps to achieve both world leading accuracy and low latency.
Slimx is Feature Packed
All Slimx cameras can be used as a reference video source - with synchronized, calibrated overlay. Deliver and/or record full resolution, full frame rate video with 3D overlay of markers, rigid bodies, skeletons, etc.


Mix and Match Cameras
OptiTrack cameras work together seamlessly to build the perfect motion capture system for any use case.

Easy set-up
Compact, high-quality grayscale video enables image preview with multiple cameras, simultaneously—an indispensable tool for camera aiming and focusing during rig setup and calibration.
Zero Drift. Pure Precision.
Motive calibrates automatically and continuously with data collected during normal use of the system. No longer does your calibration degrade over time with changing temperatures or challenging building movement—it is always a “fresh” calibration.
Motive is behind every seamless workflow
OptiTrack’s Motive software delivers speed, precision, and ease of use, streamlining everything from calibration to real-time streaming, while tools like Aim Assist and auto-masking make even large system setups simple for one person.
