LensCast

Turn your phone into a networked camera: web, MJPEG and RTSP streaming
New in version 0.1.7
Since 0.1.6:
• UnifiedPush: detection alerts can now reach a paired Android receiver through a UnifiedPush distributor - opt-in, end-to-end encrypted, and independent of browser Web Push
• The web server now stays foreground between streams, so alert delivery is not blocked by Android's background-network firewall (adds only the normal FOREGROUND_SERVICE_CONNECTED_DEVICE permission)
• HTTPS: toggling no longer fails with address-in-use, open dashboards follow the switch to the new scheme and por
LensCast turns your Android device into a networked camera station with professional controls, remote web access, interval photography, and scheduled recording.

Camera
• Live preview with a professional quick settings bar
• Manual controls: exposure compensation, ISO, white balance, focus mode, zoom
• Multi-lens support (ultra-wide, wide, telephoto) with runtime lens switching
• HDR, image stabilization, resolution up to 4K, frame rate 15–60 fps
• Photo capture and video recording
• Night vision / IR mode, scene modes, manual focus distance, color temperature

Live streaming
• Real-time MJPEG video streaming to any web browser on the same network
• Low-latency in-browser playback (WebCodecs over WebSocket) with automatic fallback to MJPEG and HLS
• RTSP streaming with AAC audio and H.264/H.265 video at 480p/720p/1080p for VLC, OBS, and NVRs
• ONVIF Profile S device service (off by default) so NVRs such as Home Assistant can discover the camera
• HTTPS mode with a self-signed on-device certificate

Web dashboard
• Watch the live stream, browse and download photos and recordings
• Full remote control of camera and stream settings
• Optional password authentication

Automation
• Object detection gate (optional): the open-source EfficientDet-Lite0 model — Apache-2.0, downloaded on demand with a pinned SHA-256 from TensorFlow's official hosting — triggers MQTT alerts or recording when configured objects appear
• Sound-event gate (optional): the open-source YAMNet model — Apache-2.0, also downloaded on demand with a pinned SHA-256 — triggers alerts or recording when configured sounds are detected
• Interval photography and scheduled or continuous recording
• Quiet hours for notifications

Optional network services (all off by default; each runs only when you enable and configure it)
• Telegram backup: auto-uploads new captures to the Telegram chat you choose (api.telegram.org)
• Web Push notifications: delivers encrypted detection alerts through your browser vendor's push service (such as Google's FCM or Mozilla's autopush)
• Model downloads: the optional detection models above are fetched on demand from TensorFlow's official hosting on Google Cloud storage
• STUN server for WebRTC streaming (WHIP push / WHEP viewing): blank by default, so streaming stays on your local network without contacting any third-party server

No ads, no tracking, no cloud defaults. All processing stays on your device; the web dashboard is served by a built-in HTTP server on your local network.

Note: the F-Droid build ships without the in-app self-updater; updates come from F-Droid.

    • New in version 0.1.6
    Since 0.1.5:
    • Localization: the camera dashboard is now fully translated — the Web/RTSP stream buttons' screen-reader labels, the thermal warning banner, the server status line, the quality badge, and the connection stats panel were still hardcoded in English
    • Proper plurals in every language: "2 viewers connected" instead of "2 viewer(s) connected", with correct Russian and Chinese plural forms
