Does the App reveal its IP address?
Or can you identify the camera in the DHCP table of your router perhaps?
Once you know its IP address it is typically best to access it using the Internet Explorer browser (not Edge).
Just enter the camera's IP address into the browser's address bar.
Normally you would initially see the camera's login page.
Enter your user name and password and you should be able to see live video and the camera's configuration settings.
