hard🚀 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Understand motion detection logic
Comparing consecutive frames detects motion by measuring pixel differences.Step 2: Save image conditionally
Saving only when difference exceeds threshold avoids unnecessary storage.Final Answer:
Compare consecutive frames, save frame if difference exceeds threshold -> Option BQuick Check:
Save images only on motion detection [OK]
Quick Trick: Save images only when frame difference is significant [OK]
Common Mistakes:
MISTAKES- Saving all frames wastes storage
- Ignoring PIR sensor state
- Saving on fixed timer without motion check
