+# Analysis Module
+
+Computer vision and audio analysis utilities.
+
+## Planned Components
+
+### motion.py
+Simple motion detection using frame differencing.
+- Compare consecutive frames
+- Threshold for "significant" motion
+- Returns bounding boxes of movement
+
+### audio_classify.py  
+Audio event classification using YAMNet.
+- Runs on Orin (GPU accelerated)
+- Classifies: speech, dog bark, door, music, etc.
+- Returns event type + confidence
+
+### vad.py
+Voice Activity Detection.
+- Silero VAD or energy-based
+- Filters silence before sending to classifier
+- Reduces bandwidth and processing
