Video doorbell motion detection: zones, people and packages

Before you decide

• Decision to record: Judge detection by approach path, alert timing and false triggers rather than feature labels alone.
• Comparison to make: Pixel-based motion, passive infrared sensing and classified alerts behave differently. A narrow path across the frame can trigger more reliably than someone walking directly towards a poorly angled camera.
• Trade-off to accept: Tighter zones reduce traffic alerts but can miss a visitor at the edge. People or package labels are probabilistic and may require a subscription; they do not replace reviewing the clip.
• Evidence to verify: Test day and night with different visitors, delivery positions, rain and street movement, then tune sensitivity gradually.
