Hello @張宜盈,
welcome to this moderated Azure community forum.
Although @Abhishek Singh share valuable links, this does not answer your question directly.
Azure IoT Central is a Software as a Service solution around popular Azure IoT resources.
The ingestion of IoT data is done via an internal IoT Hub.
This IoT Hub can ingest messages having a byte array body.
Normally we see the body actually contains a JSON message as byte array.
You want to ingest a video stream in IoT central.
The internal IoT Hub does not support that format.
What could be possible if you expose the public endpoint of your local stream in the body as a string so the user can use some reader (like VCL) to connect to the stream.
Be aware you are exposing a stream publicly so basically everyone knowing the address could look at the stream.
More mature solutions keep the stream locally and have (vision) AI look at the stream. Depending on the model, alarm signals are sent to the cloud. Passing on a still could be a solution too.
