A fast tracking system is demonstrated that is based on single laser illumination and a few single‐pixel single photon avalanche diode (SPAD) detectors that improves on the previous tracking of non‐line‐of‐sight motion by a factor of 300 in laser power. With an average illumination power of only 2 mW, a 15 cm ×15 cm object located up to 2.5 m away is tracked whilst outside of the direct line‐of‐sight and moving at approximately 6 cm/s.
