Frequently asked questions
What is ONVIF?
ONVIF (Open Network Video Interface Forum) is an industry standard that lets IP cameras and viewer apps from different manufacturers talk to each other. A compliant camera can be auto-discovered and streamed without needing a brand-specific app or manually entering an RTSP URL.
What is the difference between ONVIF and RTSP?
RTSP is the protocol that carries the actual video stream. ONVIF is a higher-level standard for discovery, authentication, and control — it tells the app where the RTSP streams live and what the camera can do (PTZ, audio, events). Most modern IP cameras support both.
Which cameras support ONVIF?
Most professional and prosumer IP cameras support ONVIF, including Hikvision, Dahua, Amcrest, Reolink, Uniview, Axis, Bosch, and Vivotek. Consumer-only cloud cameras like Ring, Nest, and Arlo generally do not. Check the spec sheet for ONVIF Profile S compliance.
How do I find my camera's ONVIF port?
ONVIF usually runs on port 80 or 8080 over HTTP, with RTSP streams on port 554. Open your camera's web interface and look under Network or Advanced settings for an ONVIF entry. If ONVIF is disabled by default, you may need to enable it and set a username and password.
Do I need ONVIF Profile S or Profile T?
Profile S covers basic live video streaming and PTZ control and is enough for most viewer apps. Profile T adds H.265 support, imaging settings, and richer motion events. If you only need to watch the live feed, Profile S is sufficient.
Does an ONVIF camera app require a cloud account?
No. ONVIF is a local network protocol, so a proper ONVIF viewer connects directly to cameras on your Wi-Fi without any cloud account, vendor login, or internet connection. Video stays between the camera and the iPhone on your local network.
