When Stereo-cap is the right fit

Best forRobotics teams, physical-AI labs, and data programs capturing hands, objects, close-range manipulation, and spatial task work
Choose stereo whenThe workflow needs synchronized left/right video, calibrated geometry, and high-rate motion data
Capture modelSessions record locally to the receiver with removable storage; phone control works without a laptop in the capture loop
ScopeCapture hardware only; no built-in hand tracking, 3D pose estimation, cloud processing, or tactile sensing
