Video steam with an old smartphone

Hey guys, I know, many people have just asked the same question but in there answers I did not find what I need.
To my project. I want use an old smartphone as an IP camera, so that I do not have to buy a new one :slight_smile:
Than I want use it to steam a video on Blynk app. To my question: Does somebody know an app with it I can "convert " my smartphone into a ip camera where I have later the right format to steam on Blynk. Until now I did not found one which a compatibility with Blynk.
To the owners from Blynk: I read that you want translate our website and the documents in more languages. German would be one of the missing languages which I miss.
Thanks a lot guys :stuck_out_tongue_winking_eye:

Then you are not looking hard enough :stuck_out_tongue_winking_eye: … I for one, have mentioned two different Apps that I use with old phones and Blynk.

You have to experiment with different settings from there.
