Android IP Webcam monitoring and alert

Transform an Android phone with IP Webcam into an intelligent Edge AI security system with OpenClaw.

Security monitoring over IP Camera Android app

Use the Clawd Sentinel pattern to turn any old Android smartphone into a sovereign, frugal, and intelligent motion detection system.

Setup

1. Android Side: Install "IP Webcam" (by Pavel Khlebovich) and start the server.
2. Connectivity: Note the local IP (e.g., 192.168.1.100:8080).
3. OpenClaw Workspace:
   • bin/sentinel_ultra_frugal.sh: The core logic for pixel comparison.
   • bin/sentinel_runner.sh: The background loop runner.

Detailed API Interaction

The IP Webcam server provides a REST-like API for full remote control. Base URL: http://<IP>:8080/

Visual Captures

• Standard Snapshot: /shot.jpg (Fastest, current frame)
• Autofocus Snapshot: /photoaf.jpg (Triggers autofocus before capture, highest quality)
• Video Recording:
  • Start: /startvideo?name=alert_123
  • Stop: /stopvideo
  • List recordings: /list_videos (returns JSON/HTML)
  • Download: /v/<filename>.mp4

Camera Control & Settings

• Focus Distance: /settings/focus_distance?set=<0.0-10.0> (0.0 is often Infinity)
• Torch (Flash): /enabletorch | /disabletorch
• Focus Mode: /settings/focusmode?set=<on|off|macro|infinity|fixed>
• Scene Mode: /settings/scenemode?set=<auto|night|action|party...>
• White Balance: /settings/whitebalance?set=<auto|daylight|cloudy...>

Device Telemetry

• Sensors Data: /sensors.json (Battery, light level, proximity, accelerometer)
• System Status: /status.json (Camera state, recording status, uptime)

Audio

• Audio Feed: /audio.wav or /audio.opus (Live audio stream)

Integration Examples (curl)

bash

# Get battery level via jq
curl -s http://<IP>:8080/sensors.json | jq '.battery_level[0][1][0]'

# Toggle flash remotely
curl http://<IP>:8080/enabletorch

Recommended Thresholds

• Daytime (Haze/Clouds): 2500
• Nighttime (ISO noise): 1500

Notes

• Frugality: No tokens are consumed unless the pixel differential exceeds the threshold.
• Privacy: Raw frames remain local. Only alert-triggered frames are sent to the AI.
• Maintenance: Periodically check phone battery and Wi-Fi stability.
• Lens flare: Long rainbow flares in night mode usually indicate static lights, not vehicles.
