Motion detection is implemented by integrating the Camera2 API to capture preview frames and applying frame-difference analysis across an adjustable tripwire region. When motion crosses the tripwire, the system triggers a timing event broadcast.

The best way to broadcast timing events is using LAN sockets for low-latency transmission across devices. Supabase Realtime can be configured as a fallback networking mechanism when direct LAN communication is unavailable.

Frame-difference motion detection works by comparing consecutive camera frames to identify pixel changes. In a sprint timing context, an adjustable tripwire region isolates the detection area, triggering a timer event only when movement crosses that specific boundary.

Yes, you can use Supabase Realtime with Kotlin for Android camera-based timing. It serves as a fallback networking layer to broadcast timing events across devices when low-latency LAN sockets are not available in your deployment environment.

Camera2 motion detector crashes during frame processing often result from improper lifecycle handling or preview management. Debugging workflows should verify camera initialization, validate frame processing logic, and apply performance tuning patterns to resolve instability.

You need LAN sockets if you require low-latency timing transmission across local devices. If LAN sockets are unavailable, Supabase Realtime is the documented alternative fallback for broadcasting timing events over a broader network.
