The cameras on the new phones (Galaxy, Pixel, iPhone) are incredible. I used to do the GoPro set up for all my YouTube videos until I realized that the difference between my old iPhone (7 plus at the time) and GoPro was minimal, in fact I thought the iPhone was better.
I currently use the Google Pixel and the quality is amazing.
Lot of company's nowadays sell product that can turn your phone into a nice camera set up.
Outside of cell phones any entry/mid level camera set up will work. I wouldn't recommend a DSLR as it requires a little more work, but something like a Sony Cybershot could work.
