sentinel
Transform an Android phone with IP Webcam into an intelligent Edge AI security system with OpenClaw.
Best use case
sentinel is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Transform an Android phone with IP Webcam into an intelligent Edge AI security system with OpenClaw.
Teams using sentinel should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.

# 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.

Meeting Prep
Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.
self-improvement
Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.
