Background vs Sensor Demo

Sensor Transmitter Pattern Comparison Demo Audio Background Demo

Uses a camera/simulated sensor stream and compares each incoming sample against a rolling background model. Every sample tick updates rolling mean, stddev, and z-score = (sample - mean) / stddev.

Configuration

Sample source

Sample rate (Hz): 20

Window size (samples): 200

Z threshold: 2.00

Sigma floor: 4.0

Delta floor: 15

Freeze background on event

Camera Source

Camera source status

Simulated source active.

In camera mode, each sample tick averages frame luminance across the highlighted circular sample diameter and feeds it into rolling mean/stddev/z-score stats.
