On the July 13, 2019, episode of The Kim Komando Show, a caller asked about dash cam technology to install on his vehicles to help with some family issues.
Kim recommended that you can find dash cams for over $100, but you don't need to spend that much. She also recommended to the caller that he and his wife try dash cam apps for their smartphones or smart devices.
