Features
Video & Audio Codecs
CamRelay supports a range of video and audio codecs to work with different Android devices and RTSP clients. Video: H.264, H.265/HEVC, and AV1, depending on device hardware. H.264 provides the broadest compatibility. Audio: Opus, AAC, and G.711 (μ-law and A-law). G.711 is always available, AAC is supported on most devices, while Opus availability depends on device capabilities. The available codecs can also depend on the capabilities of the receiving RTSP client.
Two-Way Audio
Go beyond one-way camera monitoring with RTSP backchannel audio. CamRelay supports two-way communication when used with Frigate NVR and other compatible clients that support the relevant RTSP backchannel implementation. With a compatible setup, the client can receive audio from the Android device and send audio back to it over the network. This makes CamRelay suitable for applications such as security cameras, baby monitors, pet monitoring, and remote communication.
Web-Based Remote Control
Control and monitor CamRelay from a web browser on another device connected to the network. The built-in web interface provides remote access to the camera feed, camera controls, and recorded files without requiring you to physically operate the Android device. Use a PC, tablet, or another phone as your remote control interface.

Record camera footage directly to your Android device as MP4 video files. Recorded videos can be browsed, played, and downloaded remotely through CamRelay's web interface, making the phone useful as both a live network camera and a standalone recording device.
Dashcam Mode & Live Overlays
Turn your Android phone into a connected dashcam with configurable on-screen information. CamRelay can display: - Precise timestamp - Custom camera name - Battery level - Battery temperature - GPS coordinates - GPS speed The GPS speed information is processed on the device and can be embedded into the live camera view as a HUD-style overlay. Overlay availability depends on the relevant device sensors and permissions.
Advanced Camera Controls
Take control of the Android camera instead of relying on a fixed preview. CamRelay supports features such as: - Front and rear camera switching - Torch control - Focus locking - Optical Image Stabilization (OIS), where supported - Electronic Image Stabilization (EIS), where supported - HDR video, where supported Camera capabilities vary between Android devices and camera sensors.
Screen-Off Streaming
Keep the camera running without keeping the display constantly illuminated. CamRelay supports screen dimming and immersive operation, including a pitch-black display mode designed for long-running camera setups. This is particularly useful when using an Android phone as a dedicated security camera or dashcam, while also helping reduce display power consumption and OLED/AMOLED burn-in risk. Require standby lock mode - Tested with no screen lock
Automatic Startup
Use an Android device as a more dedicated camera by optionally starting CamRelay when the device powers on. This is especially useful for permanently mounted security cameras and vehicle dashcams where the phone is expected to resume operation after a reboot or power cycle. Require overlay permission on recent Android versions
Flexible Streaming Controls
Fine-tune the stream to match your network and hardware. Configure settings such as: - Video codec - Video resolution - Video codec - Video bitrate - Audio codec - Audio bitratehardware - Target frame rate from 15 to 60 FPS or higher depending on device hardware - Audio streaming This gives you control over the balance between image quality, network bandwidth, device performance, and storage requirements. Video codec support H.264, H.265, AV1 depending on device hardware. Typically H.264 is supported on most devices. Audio codec support OPUS, AAC, G.711 (ulaw and alaw). G.711 is always supported, AAC on most devices while OPUS might be lesser
