Direct answer
A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. 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 whether the feature is absent, disabled, powered but unresponsive, or showing a message. 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. Test the simplest supported configuration with unrelated accessories and optional services removed. 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. Restore only the failed prerequisite or path; do not change working layers.
Verify and stop safely
ReversibleRepeat from a cold start and complete one normal use. Follow privacy laws and do not aim beyond property boundaries.

Exact questions
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.
