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

Android Side: Install "IP Webcam" (by Pavel Khlebovich) and start the server.
Connectivity: Note the local IP (e.g.,
```
192.168.1.100:8080
```
).
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)

# 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.
