Greetings,
After extensive search in various forums and AI like ChatGPT and Gemini, I have not found a working path forward though I did find some useful URIs that seem to function with the cameras to some extent. Wondering if anyone here has suggestions regarding Samsung SVN-H6431BN cameras?

Cameras reset using the onboard reset button. Default Access Point Mode functions and broadcasts SSID accessible with WiFi password, "smartcam".

Cameras seem to be advertising two "servers"/"services" on 192.168.123.1 (HTTP and RTSP) and 192.168.123.3 (SSH).
direct hit with http on .1 prompts for user ID and password but the combinations I have found so far online do not work... "admin" with various passwords such as abcd, 4321, 1234, 4321abcd, blank, 5-1s, 7-1s, 8-0s as example. These came from various forums and AI.

Various RESTful web service calls using a browser (like Edge, Chrome, Firefox) respond with information using the various URIs published in various threads. Feel free to let me know if you need those details here but they have been easy to find so didn't want to waste time sharing all of them here... so far I have only had success with HTTP GET (using web browser and Postman) to read the various available data.

RTSP seems to be open but does not authenticate to send any streams. Not sure if that is because of AP Mode and have not found a way to change any settings on the cameras since Samsung.Hanwha/Techwin have ceased all services and support. Prior to their decision, a mobile app was used for initial setup and always worked fine for me. After initial setup, the RTSP streams worked fine. We had to reset the cameras due to changes in network infrastructure and can no longer access via the deprecated mobile app and services. However, the cameras seem to work fine. I think I simply need to determine the appropriate user ID/password combination(s) to access everything. the combination of admin/<blank> seems to work for selected data viewing but has not worked for RTSP or any other actions. SSH does not accept admin/<blank> or any of the other common combinations such as 4321, 1234, 4321abcd, 11111, 1111111, 00000000. Hoping to find someone who has cracked this situation so we can continue to use these handy little devices.

Thoughts?
