70mai 4K T800 Dash Cam review: superior shooting from three angles...

t3.com

The 70mai 4K T800 Dash Cam seen here as a bundle option offers up no less than three different lenses. That means front and rear-facing video capture plus recording of the interior too. The 4K quality is excellent, while everything can be managed via the impressive 70mai app. Additional parking surveillance features can be tapped into, although these do require an optional hardwire kit in order to work. Even without that supplement though, the 70mai 4K T800 is a formidable dash cam option.
