can SCCMA be used over LAN? I have an Raspberry Pi 4B which has a more powerfull processor and already has Node Red installed (4 cores at 1.5GHz) connected over ethernet. Looking at the config node picture it looks possible, but asks for a password/username; if so what is the usernane and password or where are they set?

Yes, SCCMA should be able to work over LAN. The username and password are both recamera. You can enter these credentials in the configuration node to connect.

Thanks. Is it possible to change the username and password? Also the standard Node Red settings.js file can be edited to allow password logon passwords. Is it possible to edit this file? I’m guessing you can just SSH into the device, stop NR so the file is not in use and edit the file. Is this correct?

Hello,

You can change the username and password using native Linux commands. Use usermod to change the username and passwd to change the password.

Additionally, your understanding is correct. You can SSH into the device, edit the settings.js file, and restart Node-RED for the changes to take effect.

Hello,

how can I change camera parameters, such as resolution, fps, etc. within node-red?
Is streaming of the annotated images (model output) also possible?

[nfs0619]

Hi, thanks for your question!

Currently, the RTSP stream is fixed at 1080p and 15fps, which we've found to be the most stable setting during testing — so these parameters can't be changed at the moment.

As for the annotated images, the drawing of the bounding boxes is handled in the Node-RED frontend (via frontend code), which helps reduce the load on the device.

Hope this helps!
