1080P Full HD Dash CamThe mirror dash cam is equipped with a high-resolution 1080P screen, which ensures crystal-clear and sharp visuals of the recorded footage. Additionally, it features an impressive F1.8 large aperture. This wide aperture enables more light to enter the lens, resulting in enhanced image quality, especially in low-light conditions. G-Sensor & Loop RecordingThe rearview mirror camera has highly-sensitive G-sensor. When the car takes collision, the mirror dash camera will lock the current video to save evidence in loop recording mode. After the card is full, it will automatically overwrite the oldest videos(unlocked) to ensure enough space to save the latest emergency videos.
