Intuitive & Elegant Design
In designing the Primex series, we considered the complete lifetime of a motion capture camera—from unboxing to setup, capture, and teardown. Each process is elegantly accommodated with a nod to simplicity and usability.
On-Camera Status Indicator
Primex 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.
“Fast Glass” Lens Engineering
We custom design ultra–low distortion “fast glass” lenses for optimal tracking. The Primex 41’s lenses feature a wide-band anti-reflective coating for greater light transmission, larger volumes, and more precision 3D data.
Need a wider view? The Primex 41 offers a 51° × 51° FOV, while the 41W version expands to 65° × 65° with an 8.9 mm lens—allowing wider coverage with fewer cameras.
Incredible Range
100’ passive camera-to-marker range and over 150’ with Signature Pulse Active3, all with discrete infrared wavelengths. This provides up to 290,000 cu ft/camera for tracking passive markers and over 1,000,000 cu ft/camera for tracking of active markers.
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.
Outdoor Capture Out-of-the-Box
Primex 41 extends its incredible range for outdoor capture as well. For passive markers, the outdoor (bright sunlight, midday) range is about 50’ (16m). For Signature Pulse Active technology the range is > 70’ (21m).
Primex Equals Precision.
In-house designed low distortion lenses and true 10-bit grayscale depth reduces quantization noise and improves precision—resulting in perfectly crisp and beautiful images, better centroids and better 3D accuracy. Megapixels matter, but image quality matters more.
Easy Set-Up
Aim assist and easily accessed lens controls make the Primex 41 fast and easy to set up.
Track Anything and Everything
OptiTrack's foundation. Retroreflective passive markers, illuminated by the cameras themselves, deliver the sub-millimeter accuracy that has defined motion capture for decades. From character animation to biomechanics to elite sports analysis, marker-based tracking remains the gold standard for capturing complex human and object motion with absolute precision. Shop cameras
Primex is Feature Packed
All Primex 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.
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.

Designed & Manufactured Under One Roof
- 3D accuracy referenced is typical for a 30'×30' (9m×9m) tracking area. Range is estimated using a 14 mm marker with cameras at an exposure of 800, gain of 6, and the lowest f-stop.

Frame Rate | Resolution | FOV (standard 12mm lens) |
|---|---|---|
180 fps | 2048x2048 | 50°×70° |
240 fps | 2048x1528 | 50°×70° |
500 fps | 2048x720 | 50°×46° |
1000 fps | 2048x352 | 50°×24° |
- Signature Pulse Active markers provide their own unique ID, resulting in 100% error free labels. When introduced into the tracking area, the LED markers are acquired in < 0.1 seconds. Unique marker placements based on spatial separation, normally required for passive marker tracking, are not required for distinguishing multiple rigid bodies.
