Quick answer

Turn your phone into a networked camera: web, MJPEG and RTSP streaming

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.

What’s new

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
• No other changes — this release carries no new permissions, no new network endpoints, and no beha

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
