Re: Start offering evidence
"So.. help me out. how do i untether it and make it my OWN controllable camera?"
The obvious solution, and the one that I had in mind, was not buying a camera that was tethered to a cloud server in the first place - my local electronics store has a number of such devices available off the shelf - they even sell complete systems with cameras and server that you can install at home and configure however you want.
As with many technical things, research before purchase, not purchase before research.
For a start, here is one link to setting up the necessary VPN server at your home - as a side advantage, once you've got this set up and working you will have secure* access to all your home network, including any NAS, printers, etc. I also use it when connected to public WiFi as I am confident that my fibre connection at home is less easy to hack than some random WiFi access point with the password prominently displayed.

If you enter "set up vpn server on rasp pi" into DuckDuckGo (or Google, if you must) you will get a number of links that will guide you through doing this, some may suit your needs better than others.
I personally have found DuckDNS to be a reliable way of dealing with having a dynamic IP address on my home internet connection, but I've no doubt there are other such services for a similar price ie., free. I've set my system up to ping DuckDNS every 5 minutes, so I'm never more than 5 minutes away from being able to access my VPN should the IP change.
