That's $140 off.Vantrue N4S 3-Channel Dash Cam$290 at amazon.comIf you're serious about security, a three-channel dash cam that records the front, rear, and inside of your vehicle is the ultimate for peace of mind. We highlighted the Vantrue N4 in our comprehensive testing of the Best Dash Cams, and Vantrue has since improved on that dash cam with the more powerful NS4.For a long time, the N4 stood as our top overall pick thanks to its outstanding value, with front, cabin, and rear coverage in one affordable package. However, as sensor technology evolved, the N4 lost its crown to competitors that had superior image quality.Enter the Vantrue N4S. While we haven't formally tested this exact model—though its successor, the Vantrue N5S, is currently one of our top picks—its spec sheet directly addresses most of our minor gripes with the original N4, indicating that the great budget three-channel setup has transformed into a high-tech powerhouse.VanTrueThe biggest game changer is the addition of triple Sony STARVIS 2 IMX675 sensors. In the dash-cam world, Sony's STARVIS 2 is the gold standard for low-light clarity and dynamic range. Instead of the older N4's 1440-pixel and dual-1080-pixel resolution split when all cameras are active, the N4S pushes 2.7K resolution out the front and a crisp 2.5K for both the cabin and rear cameras. It also features Vantrue's exclusive PlatePix technology, which optimizes the front camera's exposure to snag clear, legible license plates.Vantrue also supercharged the hardware. The rear camera is now IP67-rated waterproof, meaning you can mount it externally for an unobstructed view. Connectivity gets a massive boost too, as 5-gHz Wi-Fi and an improved app experience now let you download footage to your phone without pulling the microSD card.While you can certainly find reliable dual-channel setups in our roundup of the Best Dash Cams Under $170, getting complete 360-degree coverage with triple STARVIS 2 night vision and an exterior-ready rear camera is rare at this price point. You'll have a difficult time finding a better full-coverage option dollar for dollar, especially from a brand that's been a multi-time Best Overall winner in our comprehensive dash-cam testing.If you've been considering a dash cam, want to upgrade your current setup, or are thinking of giving a dash cam as a holiday gift, now's the time to strike.Gift Guide: Best Ride-On Electric Cars for KidsFuture Cars Worth Waiting For: 2025–2029
