Cameras for the vehicle

[Shourty]

I had an individual reckless drive around me this morning. They came up fast behind me, swerved into the land next to me and hugging the line passed me swerving in front of me and slowing down.
I sure felt scolded for my driving. I'm sure I learned my lesson.
I'm now thinking of putting cameras in the rear and front window of my car.
Any suggestions on what is a good setup? I'd like to be able to download the recordings to my fone I spose. Not sure what is available.
I'll do the regular inernet search but you folks are my go to for stuff like this.

Thanks.
