Primex 120
Primex 120
Primex 120 sets the standard for high-precision 3D motion capture in large volumes.
Long Range Performance
The Primex 120 and Primex 120W cameras offer OptiTrack’s longest camera-to-marker range for Passive and 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 and more.
“Fast Glass” Lens Engineering
OptiTracks engineering team custom designs ultra–low distortion “fast glass” lenses for optimal tracking. The PrimeX 120’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 120 offers a 51° × 39° FOV, while the 120W expands to 65° × 51°—delivering wider coverage with fewer cameras.
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.
New, higher output strobe. Ultra high power LEDs provide improved range for any given shutter setting. The world’s longest range motion capture camera just got even better.
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.
Tracks Passive and Active Markers
With positional errors less than +/-0.10mm and rotational errors less than 0.5 degrees. For some tracking applications, customers find benefit in using a combination of active and passive markers.
Easy Set-Up
Aim assist and easily accessed lens controls make the Primexcameras fast and easy to set up.
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.
Primex is Feature Packed
Full Resolution Grayscale Reference Video
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.
OEM & Computer Vision Integration
Incorporate Primex cameras into OEM tracking or computer vision applications via the free SDK, a C/C++ interface for control of and access to raw camera frames, image processing modes, camera settings, 2D object data, camera synchronization and all 3D data.
Full Resolution Grayscale Reference Video
With the eSync 2, cameras sync to nearly any source, including Genlock and SMPTE Time Code, for precise, flexible hardware synchronization. Trigger force plates, EMGs, and DAQs, or manage events through inputs and software commands, with full customization available via OptiTrack’s free, open SDK.
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.
- 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. ↩︎
