At least 1080p resolution: A dash cam’s video-whether captured in light or dark conditions-has to be sharp and distinct enough that you, a lawyer, your insurance company, or a member of law enforcement can read license plates and see other details clearly.The N4 also lacks built-in GPS tracking, but you can easily add that by buying a GPS mount ($20 at this writing) from Vantrue. But we think most people wouldn’t miss that feature, as it’s still fairly convenient to view footage on the camera itself or with a microSD card reader. Unlike some of our other picks, the N4 lacks app connectivity for you to view and download video remotely. And although it isn’t as well suited for sub-freezing temperatures as our other picks, it is designed to work even in extremely hot climates such as in the American South and Southwest. It has an intuitive menu, and its control buttons are clearly marked and readily accessible. It’s compact (a little smaller than most point-and-shoot cameras) and relatively unobtrusive on a windshield, and its 3-inch screen is bright and easy to read. In addition to a front-facing camera, it has interior and rear cameras, so it documents your car’s movements (and your surroundings) from three different perspectives. The Vantrue N4 is packed with premium features such as 2160p (4K/UHD) resolution in its main camera, night vision, and 24-hour parked-car monitoring to catch hit-and-run perpetrators, yet it costs half as much as some comparable models.
