A 4K dash cam with front and rear cameras is a high-resolution vehicle camera system that simultaneously records ultra-clear video of the road ahead and behind your car, providing comprehensive coverage for safety and security. With 4K (Ultra HD) resolution capture, it delivers detailed footage even in challenging light conditions or at higher speeds, helping you clearly see license plates, road signs, and critical events. Built-in features—such as loop recording, night vision, motion detection, and a G-sensor that locks important clips during impacts—ensure important incidents are saved automatically. Easy to install and ideal for daily driving, rideshare use, or road trips, a front and rear 4K dash cam gives you peace of mind, reliable evidence for insurance claims, and continuous protection on every journey.
