Protocols and video formats
What the app uses for discovery, live video, login, camera controls and dense grids.
Streaming
- RTSP over TCP is the default. Standard and Pro add a UDP option with loss detection and fallback.
- H.264 and H.265 are supported. MJPEG-only cameras are not.
- Grids use the camera's lower-resolution substream where one exists. Fullscreen uses the main stream.
- Grid tiles are muted on purpose. Clips carry the camera's sound, and the Hub shows a wave while a picture is making any.
Discovery and control
- ONVIF WS-Discovery finds cameras over multicast when the router allows it.
- Subnet scan is the fallback. Any camera can also be added by IP or RTSP URL.
- ONVIF Media gives us stream profiles, Device gives model info and reboot, Imaging may expose IR-cut.
- Controls only appear when the camera reports the capability. Some firmware advertises features it then ignores.
Login
ONVIF UsernameToken plus RTSP Basic or Digest. Credentials live in the system keychain. Keep them out of screenshots and support emails.
