- Phone in handA phone the detector recognises, within a phone-length of the student's hand, for most of a second.
- Leaning over to copyThe head moves sideways away from the student's own hips, compared with how they sit upright.
- Looking awayThe head turns away from the student's own usual direction for 2+ seconds — not from a fixed angle, so a camera at an angle doesn't make everyone look guilty.
- Passing somethingTwo students in the same row, one reaching toward the other, hands close together.
Every alert is a clip, a time and a reason for a person to review. None of it decides that anyone cheated.
