Does anyone have one of these Cameras ? Struggling to find its stream address to bring it into home assistant
I would try and refund that camera, with its subscription based storage. And more importantly no onvif so you’ll have a hard time integrating it into HA
Also any site that shows so much marketing BS without any real specs or manuals/support
is best avoided 
If it shows up on your network maybe you can login and find what the actual manufacturer is and find out that way.
Returned - any suggestions for a battery up camera
