Office Cam

office-cam

Multi-camera surveillance system with motion detection, continuous monitoring (Overwatch mode), and AI-powered analysis. Perfect for office/home monitoring with random check-in alerts.

Features

📸 Tier 1: One-Shot Capture

Instant visual Q&A on demand:

• capture.sh — Take a photo from the office camera
• Ask "Is anyone here?" and get instant AI analysis
• Great for quick status checks

🎥 Tier 2: Motion Detection

Continuous monitoring with configurable alerts:

• motion-detect.sh — Detect motion and alert on change
• File-size comparison method (fast, reliable)
• Configurable cooldown and threshold
• Three modes:
  • report-all — Alert on ANY motion
  • report-suspicious — Alert only on threats (weapons, breaking, etc.)
  • report-match — Alert on exact BOLO text match with strict feature matching

🕵️ Tier 3: Overwatch (24/7 Monitoring)

Background daemon with automatic check-ins:

• overwatch start — Launch continuous background monitoring
• overwatch stop — Stop the daemon
• Saves motion alerts to ~/.clawdbot/overwatch/
• Random check-ins — Periodically takes snapshots and posts GIF updates to Telegram
• AI analysis on every trigger
• Automatic image storage and cleanup

🎯 Tier 4: BOLO (Be On Lookout)

Visual fingerprinting and exact matching:

• Upload a photo → auto-extract features (faces, clothing, items, etc.)
• Monitor for exact matches across angles/lighting/distance
• Critical features (moles, scars, plates) MUST all match
• High priority features (hair, eyes, vehicle type) should match
• Medium/low priority features can vary

🎬 GIF Reactions

• Random check-in captures paired with GIF reactions ("spy camera", "watching", etc.)
• Makes alerts fun and conversational
• Telegram integration for instant notifications

Multi-Camera Support

USB Webcam

# Find your camera
ls /dev/video*

# Capture from USB
ffmpeg -f avfoundation -i "0" -frames 1 photo.jpg

Wyze Camera (RTSP)

# Configure WYZE_IP in .env
ffmpeg -rtsp_transport tcp -i "rtsp://wyze_ip:554/live" -frames 1 photo.jpg

ESP32-CAM

• Firmware sends images via HTTP POST to media receiver
• Analyzer polls for new images and processes them
• See guides/esp32-setup.md for full setup

Troubleshooting

No images captured

• Check CAMERA_SOURCE is correct: ls /dev/video*
• Verify permissions: ls -l /dev/video0
• Try manual ffmpeg: ffmpeg -f avfoundation -i "0" -frames 1 test.jpg

Overwatch not alerting

• Check daemon is running: ./scripts/overwatch status
• Verify GROQ_API_KEY is set: echo $GROQ_API_KEY
• Check logs: tail -f ~/.clawdbot/overwatch/overwatch.log

Motion detection too sensitive

• Increase MOTION_THRESHOLD (default: 10%)
• Increase MOTION_COOLDOWN (default: 180s)
• Reduce MOTION_INTERVAL (default: 2000ms)

BOLO matching too strict

• Adjust feature priority weights in scripts/bolo-analyzer.js
• Use --strict flag for exact matching only

Performance

• USB Webcam: Real-time, <500ms per capture
• Overwatch: ~2-5s per check including AI analysis
• Motion Detection: <1s detection, configurable interval
• Groq Vision: ~1-2s analysis per image

Privacy & Security

✅ Secrets are .gitignored — Never commit API keys, credentials, or auth tokens ✅ No cloud storage — All images stored locally in ~/.clawdbot/overwatch/ ✅ Local analysis — Groq API used only for vision analysis (encrypted transit) ✅ Configurable retention — Images auto-cleaned after retention period

Integration with OpenClaw

Heartbeat Monitoring

Add to your HEARTBEAT.md:

# Check for overwatch triggers
ls ~/.clawdbot/overwatch/triggers/trigger_*.json 2>/dev/null | wc -l

Cron Jobs

# Random check-in every 15 minutes
openclaw cron add --schedule "every 15 minutes" --task "office-cam check-in"

Natural Language

"Is anyone in the office?"
→ Takes photo + analyzes → "No one detected"

"Watch for movement"
→ Starts Overwatch + sends check-in GIFs

"Look out for a tall person with a blue jacket"
→ BOLO mode + feature matching active
