That's nearly one-third off, bringing the total to $119. It's a solid price for a quality dash cam or a great backup camera; this WolfBox is both.The G840S's massive 12-inch screen straps over your vehicle's existing rearview mirror—no dealing with pesky suction cups or, even worse, drilling holes. This gives it three duties: dash cam, backup camera, and rearview live feed. Just like your existing rearview mirror, only without obstruction from the seats.Setup is easy: It plugs directly into your vehicle's 12-volt outlet, and the rear camera is hardwired in via a 20-foot cable. Yes, you'll have to route the cable somewhere, but the length is plenty long.Camera feeds from both the front- and rear-facing units can be displayed on the screen at the same time, and the G840S can also record video from both cameras simultaneously. The image quality truly is excellent, and the capable sensors provide stellar low-light video with negligible flaring from headlights.So to scoop up this excellent value at an additional discount, check it out by 11:59 p.m. PT October 7, which is when Amazon Prime Big Deals Days end.Gift Guide: Best Ride-On Electric Cars for KidsFuture Cars Worth Waiting For: 2025–2029
