Blaze Configuration

Create a user for Lumeo

Create a Blaze user for Lumeo with appropriate permissions to generate events. Provide this username and password in this node's settings.

Skip Blaze Channel ID if source is a Blaze camera/stream imported into Lumeo

If your video source is an RTSP stream from Blaze (e.g. rtsp://<blaze-host>/<channel-id>/primary), you can leave the blaze_channel_id field empty. Lumeo will automatically extract the Channel ID from the stream URI.

Associate Lumeo source with Blaze camera

Follow the steps below if you set up the camera or stream directly in Lumeo without sourcing it from Blaze:

Create an RTSP stream or ONVIF Camera directly in Lumeo
Find the corresponding Channel ID from the Blaze admin console
Add the Blaze Channel ID to the Trigger Hanwha Blaze Event node in Lumeo
