Best all around dash cam?

I’m sure this question has been asked many times before, but recently in my city there have been tons of crazy drivers getting into crazy accidents and police officers giving out unjust tickets. I’ve been looking into dashcams for a while and want to get one honestly just for the peace of mind. I want it to have quality front and back recording with audio and other essential features, preferably not too difficult to install. Budget is probably around 200 but the more affordable the better. I’m just trying to get a few honest opinions on good and reliable products so any and all suggestions are greatly appreciated!
