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

It depends on how old the system is. We recently replaced a system I was installed in 2012. The cameras for that system or a model that have been around for a couple years already so figure what your cell phone camera looked like in 2009.
Our newest system records high definition. Of course it has to be set to keep everything in relative focus. It doesn’t know what you want to focus on and it’s possible there are a dozen things under the need focused on at the same time. That means everything’s a little bit blurry.
We record high quality video but when it comes time to get it out of the system we don’t always export as high quality. I recently saved some video of what could have potentially been a kidnapping of a child by his grandmother and non-custodial father as part of a difficult divorce. The camera was mounted 20 ft up and covering areas that were up to 150 ft away. 15 minutes of video was 140 mb compressed. It’s common to export really low quality versions to pass around for information, but then export the really high quality if it’s needed for any court proceedings. That version is more tamper-resistant.
I’m sure that if you set your phone camera to recording video and then mounted it up on a wall for an entire day you would not see the high quality you expect.
