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.

Grab BLAZE Channel ID

Grab the BLAZE Channel ID for your camera to associate Lumeo events with the camera if your source is not a BLAZE RTSP stream.

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

Configure Button or Generic Event rules in BLAZE

Lumeo sends events to BLAZE, but to get them to show up with the appropriate camera, you need the following:

Ensure the Camera is set to allow recording in BLAZE
Create a rule in BLAZE with the button name (for Button events) or Generic Event Source name as Lumeo (for Generic events) that triggers Recording/Notifications/Bookmarks in BLAZE.
