TThis study aimed to design and validate a synchronized timing gate integrated with an HD camera sensor and grid system to measure running and throwing speed in cricket athletes. Using a research and development (R&D) approach, 24 athletes from West Sumatra participated in testing the system, which combined dual infrared gates and a 60-fps HD camera synchronized via Arduino and Python. Calibration results showed high accuracy, with a mean deviation of 0.034 seconds (98.6% accuracy) and a 2.3% error rate for throwing velocity. Expert validation indicated very high feasibility (4.72 ± 0.15). The prototype improved precision, automation, and cost efficiency, offering an affordable and reliable tool for sport performance analysis and technology-based coaching in Indonesia. © 2026 by the authors.
