CallerCam

CallerCam is the dead-simple SRT contribution camera. If you can scan a QR code and press one button, you can go live. Built for camera operators, streamers, and broadcast crews who need to send a clean, low-latency feed to a gateway without wrestling with settings in the field. HOW IT WORKS The producer generates a QR code with the connection details using the free CallerCam QR generator (linked in Settings and on the support page; it runs entirely in the browser). You scan it, a plain-language card confirms exactly where you're about to stream, and you press the one red button. That's it — you're live. No typing IP addresses, no jargon, no manual. STREAMING - Hardware-accelerated H.264 video and AAC audio over MPEG-TS/SRT - Presets: 720p30, 1080p30, 1080p60, with the frame rate declared in the stream itself so gateways never have to guess - Live camera preview the moment you open the app, so you can frame the shot before going live - AES-128/256 encryption, configurable stream ID and latency - Adaptive bitrate that cuts on sustained packet loss and recovers automatically — it survives bad networks instead of dropping - Auto-reconnect with exponential backoff: it keeps the whole session and reconnects the moment the network returns - Live device-rotation follow, front/back camera flip, and mic mute mid-stream PROVISIONING — THE WHOLE POINT - Scan a QR code and confirm on a clear card, then Save & Use or Use Once (session-only — nothing is left behind on a borrowed phone) - Saved gateways: keep a named list of the gateways you use and switch between them with one tap - Share a saved gateway with another phone as a QR code, made on your phone and hidden until you tap to show it - Manual configuration is one tap away: validated fields, Keychain-backed passphrases, one-button full wipe - No endpoint is baked in — CallerCam is gateway-agnostic and works with standard SRT receivers ALTERNATE SOURCES — A POCKET BROADCAST TRUCK - Stream a video file from your library instead of the live camera - Built-in test pattern (SMPTE bars, 1 kHz tone, burnt-in timecode, and a once-per-second sync blip) for verifying a gateway and A/V sync before you go live BUILT-IN DIAGNOSTICS - Live status: wall clock, LIVE indicator, the gateway you're feeding, uptime, bitrate, round-trip time, and loss - Your public IP on screen while you set up - On-screen debug log with optional deep telemetry for troubleshooting in the field CallerCam speaks standard SRT and fits into workflows built around common SRT gateways and tools. Bring your own gateway; CallerCam handles the camera. PRIVACY CallerCam collects nothing. There are no accounts, no analytics, and no tracking. Your connection details stay on your device and passphrases are stored in the iOS Keychain. Video and audio go only to the gateway you configure.
