Issues on camera configuration

Hi, I bought a new camera some days ago.
There isn’t a brand and it comes with its software. In Android you have Iminicam or P2PLiveCam and you can use with those apps without problems.
But I’d like to use with Tinycam f.e. but I can’t get the audio.
I don’t why I have this issue.
Furthermore I can’t set the ddns server for access out of lan because its app can’t modify those settings.
Can you help me?
