It depends, sometimes you can “buy” digital ownership from these places in the form of DRM-free files. If you are able to download the DRM-free file and make a reliable backup of it, then I could call that actual ownership. This is how I approach my music and ebook libraries. I don’t do subscriptions for streaming anything but TV.
You can even buy books directly from publishers. Recently I wanted a hardback copy of a book and it was out of stock, backordered, or absurdly high priced on all the big popular online places. Ended up ordering it for MSRP from Penguin Random House direct.
To get a camera with RTSP or ONVIF (video stream output) support, you look at the specifications of cameras that are available for sale. Web search engines should be helpful for this pursuit.
To get the surveillance functions of your camera streams (recording, alerts, etc) you install software on the Raspberry Pi that aggregates and records / analyzes the camera feeds. Zoneminder, Shinobi, and Motioneye are some examples of that kind of software.
It’s not that hard, and you only need cameras and the raspberry pi.
Pretty much any wifi camera that supports standards like RTSP or ONVIF can be made to work with open source camera stuff on the Pi. Also you can store the videos on the RPi’s storage (USB or SD)

Yeah WTF is up with that? My car does the same thing with a USB drive full of songs. It will literally play the same “shuffled” sequence over and over every time you drive. I have to take out the drive and change the files on it sometimes to make it actually Shuffle the songs’ order and that’s too much BS
One solution to that problem is to close YouTube on your device and do something else with your time.
Bandcamp is great for music downloads
