This 3 channel dash cam video recorder is equipped with three cameras to comprehensively observe road conditions in front, inside, and behind the car. It features reverse image capture, loop recording, and high-definition video to provide clear and detailed road images. The loop recording function ensures continuous recording and overwrites old footage, making it a reliable source of evidence. Please note that the built-in battery is only for time and date update, and a high-speed C10 capacity memory card is recommended. Additionally, use the original car charger and avoid changing the line without permission to avoid abnormalities.
