ELI5: How can my cellphone record and post nearly 4K video but CCTV cameras at legitimate businesses(banks, schools etc.) have such poor quality?

I’m new here and not trying to troll. I’m also very familiar with cellphones. However, after watching this episode of Dateline I don’t understand how I can record and post near professional grade videos with my phone, and the cameras outside of legitimate businesses(banks, doors to apt complex’s, schools, etc) have such low quality?? How sway?

Try to make a 24h 4K video with your phone. You will have a little problem with the storage capacity. To be able to work with less storage you could loop the video, but at least a few hours should be stored in the loop. In 4K still a lot of space. And maybe your workplace needs multiple cameras, would add a lot of Data to the list.
