feat(detector): Hidden Camera Detector — full multi-sensor app

[cloudygetty-ai]

Summary

Complete hidden camera detector app built in React Native / TypeScript, replacing the game entry point. All sensors run in parallel — designed to surface a threat reading in under 2 seconds.

Detection Methods

Sensor	What it finds	Weight
Network Scanner	IP cameras, DVRs, NVRs on local WiFi subnet — probes 9 ports, fingerprints 20+ camera vendor signatures (Hikvision, Dahua, Axis, ONVIF, RTSP…)	45%
Bluetooth Scanner	BLE cameras, IoT recording devices — matches name patterns + manufacturer IDs	30%
Magnetometer	Electronic anomalies from camera hardware — 10 Hz rolling baseline with spike detection	25%

Threat Engine

ThreatScore (0–100) aggregates all three signals with configurable weights. Levels: SAFE → LOW RISK → SUSPICIOUS → THREAT DETECTED → CAMERA FOUND. Haptic vibration triggers on HIGH and CRITICAL.

Screens (5-tab navigation)

• SWEEP — all sensors running simultaneously, live radar pulse, threat meter, magnetic graph, device list prioritised by camera confidence
• NETWORK — subnet probe with live progress bar, HTTP response fingerprinting, port inventory per device
• MAGNETIC — real-time XYZ field components, animated anomaly gauge, rolling graph with threshold line, scan tips for where to sweep
• BLUETOOTH — BLE scan with device confidence scoring, anonymous device flagging, RSSI signal bars
• LOG — persistent history of up to 100 scans with camera summaries and threat scores

Native Package Swap-in (zero logic changes)

All sensor services use useMock = true with clearly marked NOTE[P1] comments. To enable real sensors:

• Magnetometer → npm i react-native-sensors and flip flag
• BLE → npm i react-native-ble-plx and flip flag
• WiFi local IP → npm i react-native-wifi-reborn for real subnet inference

Test plan

• Launch app — SWEEP tab renders, radar shows idle state
• Tap START SCAN — radar pulses, magnetometer anomaly graph populates, network progress bar advances, BLE devices appear
• Magnetic anomaly spike triggers correct threshold label and color change
• Network device found → DeviceCard appears, cameras sorted to top
• STOP & SAVE → threat score persists, scan appears in LOG tab
• Navigate all 5 tabs while scan is active — no state loss
• High threat → haptic vibration fires
• History tab shows summary stats and per-scan camera lists
