What an installer or home owner should check on an ONVIF camera in 2026, and how that maps to the official Home Assistant ONVIF integration. It updates the older camera discussion and sits with t=153 / t=154 on cameras and VLANs.
Complexity
Beginner if the camera already speaks ONVIF on your LAN. Moderate if you are choosing a new camera or tightening a VLAN.
1. Profile S is being wound down; Profile T is the video profile to look for
ONVIF publishes product profiles so a camera and a VMS (or Home Assistant) can agree on a feature set.
- Profile S was the long-standing streaming profile. ONVIF has been deprecating it. Official ONVIF communications describe product-conformance submissions for Profile S ending 31 March 2027. After that date, new products should not be relying on a fresh Profile S listing as the way to prove video interoperability.
- Profile T is the current advanced video profile. It is the one to look for on a 2026/2027 purchase if you care about H.264 / H.265 streaming and the related ONVIF control features. Always read the camera's actual ONVIF declaration, not only the box artwork.
2. Official Home Assistant ONVIF notes
The official integration:
- Needs ffmpeg available to Home Assistant for stream handling.
- Expects a dedicated camera user for ONVIF — do not reuse the camera's admin account in automations, and do not leave the default password on the camera.
- Works most predictably with H.264 streams. H.265 can be a source of client and transcoding pain; confirm what your display path can actually play.
- Should be reached on a trusted or camera VLAN, not port-forwarded to the internet. ONVIF and RTSP are administration and video protocols, not something to publish.
- Camera firmware current; date and time from NTP.
- A unique ONVIF user with only the rights it needs.
- Main stream and a smaller sub-stream, with the sub-stream used for live cards where you can.
- Motion or event support only if the profile and the integration actually expose it for that model — test, do not assume.
- The camera sits on the camera / IoT VLAN described in the networking thread, with Home Assistant allowed to initiate in, and the camera not allowed to browse your NAS.
Choose a current Profile T camera and have it quoted in AUD. Street prices move quickly; this refresh does not freeze a model price.
