JH Auto 4K Front and 2K Rear Dash Camera 3 in Screen 32GB Card Included 170 Degree Wide Angle Wi-Fi Night Vision WDR HDR Parking Monitor

I picked this up mostly as a sort of cheap insurance policy. I actually had a $100 dash cam in my old Corolla that totally let me down during an accident—it recorded right before and right after the hit, but missed the actual jolt, which was super annoying. But even that little bit of footage helped me out with insurance because they could see I was going straight. So for 30 bucks, this thing is a steal just to have that backup evidence. It says it records in 4K, and the picture quality actually looks pretty good on both the front and back cameras. To be honest, I don’t think 4K is the most important thing for a dash cam—it’s more about the bitrate and the sensor—but for what you pay, the quality is definitely sharp enough. The setup is pretty much plug-and-play. It uses a USB-C connection and they give you a car charger and a cable that's definitely long enough to route around the trim. They also included a kit for the rear camera, so you can have it on while parking or even connect it to your car’s screen if you want. The unboxing experience was actually surprisingly nice for something this cheap; it comes in a solid box that I’ll probably keep for storing random CS project parts or cables. When you do the math, spending 30 bucks one time is way better than getting in a wreck with no proof and watching your insurance rates jump by 50 or 60 bucks a month. It’s a buy for sure if you just want some peace of mind while driving.
