How to choose a dash cam
Updated November 14, 2026
A dash cam records the road while you drive, which can help after an accident or an insurance dispute. The right one depends on whether you need just the front view, the rear too, or the inside of the car, as rideshare drivers often do.

Front, rear or cabin
Front-only cameras are the simplest. Front-and-rear kits add a second camera for rear-end collisions. Cabin cameras record inside the car and usually use infrared for night.
Video quality that matters
Higher resolution helps read license plates, but night performance matters just as much: look for a good image sensor and sample night footage from the maker.
A wide field of view captures more lanes, but very wide lenses can make distant details smaller.
Parking mode and power
Parking mode records bumps or motion while the car is parked. It usually needs a hardwire kit connected to the fuse box, which has a low-voltage cutoff to protect your battery.
Storage and installation
Dash cams loop-record over old footage and lock clips when they detect an impact. Use the type and size of microSD card the maker recommends, preferably a high-endurance card.
Check local laws on windshield mounting and on recording audio or passengers.

Questions
Do dash cams drain the car battery?
Not while driving. In parking mode, a hardwire kit with a low-voltage cutoff stops recording before the battery gets too low.
Is it legal to use a dash cam?
Dash cams are legal in all US states, but rules on windshield placement and recording audio vary. Check your state's rules.
