Direct answer
A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. For security-camera motion detection, first walk a repeatable path and compare event timestamp, first frame and alert time.
What this covers
- security-camera motion detection with this exact failure state
- Diagnosis across capture timing versus notification delay, lighting, battery sleep and zone geometry
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord the change, version, outage time or newly connected hardware and the last known working state. Expected behavior: trigger at the intended zone, direction and sensitivity without excessive false events.
Isolate the component boundary
ReversibleWalk a repeatable path and compare event timestamp, first frame and alert time. Remove or roll back only the reversible change, or test the previous direct path. Boundary to separate: capture timing versus notification delay, lighting, battery sleep and zone geometry.
Correct only the proven cause
ReversibleAim zones across travel, adjust sensitivity and improve power/Wi-Fi. Reapply compatible settings, update both endpoints or replace the incompatible new path.
Verify and stop safely
ReversibleRestart twice and confirm the feature remains stable with the intended change present. Follow privacy laws and do not aim beyond property boundaries.

Common follow-ups
What should I check first when security-camera motion detection has this problem?+
Walk a repeatable path and compare event timestamp, first frame and alert time.
Why not factory-reset immediately?+
The useful boundary is capture timing versus notification delay, lighting, battery sleep and zone geometry. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
follow privacy laws and do not aim beyond property boundaries.
