If the audio recording function is enabled, it can capture sound. Dash cams are typically equipped with external cameras, primarily designed to record the driving conditions outside the vehicle. However, they can also record audio inside the car, though they cannot capture images of the interior. The functions of a dash cam are as follows: 1. Recording various state information of vehicle operation and driver actions: This includes data such as mileage, speed, and, for models with GPS modules, the vehicle's location and travel route. Analyzing and processing the collected vehicle and driver operation information can help optimize vehicle performance and correct poor driving habits. 2. Alarm function: According to national standards, continuous driving should not exceed 4 hours, and driving time within 24 hours should not exceed 8 hours; otherwise, it will be considered fatigue driving. When a driver engages in fatigue driving without stopping to rest, the dash cam will automatically emit continuous alarm sounds, and background monitoring departments can also contact the driver for a break. The fatigue alarm helps drivers maintain a good driving state, thereby reducing the occurrence of traffic accidents. Additionally, depending on the features of the dash cam, it may also include overspeed alerts, anti-theft reminders, and vehicle fault alerts. 3. Assisting in determining liability in traffic accidents: The dash cam records the vehicle's driving status (speed, braking information, turn signals, doors, mileage, location, direction, etc.). By extracting the stored data from the dash cam, it can assist in scientifically determining liability in traffic accidents, making the process more objective.
