Phones nowadays have cameras that are so perfect in quality, yet security cameras are mostly always so grainy so why? You can get a phone with a perfect extremely high quality camera for a few hundred these days, sometimes even less

They don’t need to be high quality. They only need to record. I don’t know about high crime areas, but at my job, my low quality cameras did the job very well on most cenarios. I had to prove a employee was stealing money, had to prove a client didn’t leave her purse at my store when she acused my employees of stealing it, that another employee didn’t steal things in the locker of a coworker. All those cases I only needed to recognize the person (usually by clothes or other traits) and general shapes of things. My shitty cameras installed 8years ago did the job, why spend money in the upgrade?
That said, some security cameras do have high resolution. Again, because of work, I was in the security room of an airport once and boy. Thoses babies are built to clearly zoom in your face and are installed like 4 meters high. They also overlap with other cameras so they can have more than an angle at any time. The specific thing I was there to review had 5 angles, all high quality.
But again, cameras in your grocery store that are frequently in not that well lit areas? Those are there to detter minor things and to build in evidence provided by the statements of involved people.
