Product information "PrimeX 120W"
12 MP resolution | +/- 0.1 mm 3D accuracy1 | 300 FPS native frame rate | 1000 FPS max frame rate2
The Primex 120 camera delivers exceptional precision, tracking markers at up to 300 feet with less than +/-0.10mm positional error. Its custom-engineered 18mm “fast glass” lens offers low distortion, high light transmission, and a broad 65° x 51° FOV. It supports passive and active markers, synchronized grayscale video, and flexible system configurations for high-accuracy 3D tracking in any environment.
1.
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.

Primex equals precision. Primex cameras are designed and manufactured in-house at OptiTrack’s headquarters in Oregon to ensure our exacting quality standards are met. We design lenses with low-distortion and true 10-bit grayscale depth sensor processing which reduces noise and improves precision—resulting in perfectly crisp images, better centroids and better 3D accuracy.
Fast Glass lens. We develop our own Fast Glass lenses with extremely low distortion for optimal marker tracking. The Primex 120's standard 18 mm diameter lens features a broadband anti-reflective coating that significantly increases light transmission to the imager, delivering larger volumes and more accurate 3D data.
Choose the option with a larger field of view. The standard version of the Primex 120 offers a wide field of view (FOV) of 51° x 39°. For larger volumes that require the highest accuracy, the Primex 120W is available with an 18 mm wide-angle lens with 65° x 51°. The additional field of view allows users to use fewer cameras to capture movement in larger areas.

Tracks Passive and Active Markers with positional errors less than +/-0.10mm and rotational errors less than 0.1 degrees.
Passive markers - or retroreflective markers, including spheres, hemispheres, and even flat reflective discs, are easy for PrimeX cameras to identify and track.
Active markers invisible infrared LEDs send unique pulses for error free marker IDs with low latency data delivery and 10ms acquisition time.
Active markers are the benchmark for low latency Virtual or Mixed Reality tracking, ground truth systems for Augmented Reality, and high subject count robotics applications such as drone swarms.
Mix and match cameras. Systems can pair Primex 120 cameras with any other Primex or Prime Color cameras to create the optimal infrared configuration for any use case and deliver the highest 3D tracking accuracy to any environment.


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. Motion capture suit stretch
Full resolution grayscale reference video. All Primex cameras can be used as a reference video source - with synchronized, calibrated 3D overlay. Deliver and/or record full resolution, full frame rate video with 3D overlay of markers, rigid bodies, skeletons, etc.


External sync in/out, Genlock, and Time Code. Synchronize any Prime and Primex cameras to any signal or source with the eSync 2 with all the functionality and flexibility you’d expect with a professional tracking system. Cameras sync to dozens of sources including a professional cameras’ Genlock signal, where record and other event triggering can be managed from general purpose inputs and software commands.
Use the sync output signal as a master or to trigger force plates, EMGs and National Instrument DAQs for flexible yet precise hardware synchronization. Highly accurate frame timing can also be achieved with SMTPE Time Code for ease in editing and logging. OptiTrack’s free and open SDK allows for further customization within the timing protocols.
Expert system configuration for any space. OptiTrack has built over 30,000 tracking systems in areas of all shapes and sizes. Our experts can help guide you on the most economical and suitable tracking system for your needs—for today and the future.


It's more than just cameras. Primex cameras work hand-in-hand with OptiTrack’s Motive 3D motion capture software featuring Trained Markersets, Continuous Calibration, Skeletal Solver and more. The Primex cameras and Motive enable users to see and analyze tracking data to inform everything from robotics and movement sciences to video game animation, cinematic virtual production and location-based virtual reality.
