Active tracking perfected. Featuring a discreet profile and black matte finish, it excels in VR, AR, and drone tracking applications.

1.3 MP resolution
+/- 0.30 mm 3D accuracy¹
240 FPS frame rate
1000 FPS max frame rate

Intuitive & elegant design. In designing the Prime^x 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.

Small footprint, lightweight. The Slim^x 13’s 2.7″ square signature, 12 ounce weight and invisible 850nm IR illumination are perfect for applications which require a discreet tracking system.

240 FPS

High frame-rate capture. The Slim^x 13’s 240 FPS native capture rate and image stopping global shutter is ideal for measurement tasks of people and objects moving at speeds up to 125mph.

Mix and match cameras. Any camera in the Prime and Prime^x family can be used together to create the optimal configuration for any use case. That is 11 different cameras that can be chosen to deliver the highest 3D accuracy in any environment.

“Fast glass” M12 lenses. We custom design our own super low distortion, “fast glass” lenses for optimal marker tracking. The Slim^x 13’s standard 3.5mm and optional 4.5mm lens are treated with a wide band anti-reflective coating, dramatically increasing light transmission to the imager, yielding larger volumes and more precise 3D data.

Filter Options. Alternate between IR and visible spectrum imaging with our software selectable Filter Switcher technology, or select a band-pass filter to eliminate interference from other light sources even more thoroughly.

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.

On-camera status indicator. Your OptiTrack system will let you know what it’s up to with the user definable color LED indicator 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.

Full resolution grayscale reference video. All Prime^x 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 Prime^x 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 10,000 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. In addition to the essentials to which you’ve grown accustomed, you’ll also discover several new software features that will make you wonder how you ever got along without them. Enjoy innovations like our Continuous Calibration, where a wand wave is required on first installation only, then calibrates automatically just by using the system. No longer does the calibration degrade over time, temperature change, or after cameras are bumped

OEM & computer vision integration. Incorporate Slim^x13 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.
