As an important safety device for modern vehicles, the core function of dash cams is to record images, sounds and vehicle data during driving. The main functions can be summarized into the following five categories:
1. Accident evidence collection and liability determination
Traffic accident evidence: Record the image, time, speed and location information when the accident occurred, provide objective evidence for the traffic police or the court, and quickly identify the responsible party.
Insurance claims support: Video data can speed up the insurance claims process and avoid disputes.
Preventing fraud: Record malicious fraud behavior to protect drivers from blackmail.
2. Driving safety and driving assistance
Driving behavior analysis: Help drivers improve bad driving habits (such as sudden braking, speeding) by replaying videos.
Supervision and restraint function: After installation, it encourages drivers to drive more standardized and reduce the accident rate.
Lane change assistance and blind spot monitoring: Some high-end models support wide-angle shooting or blind spot monitoring to improve safety.
3. Parking monitoring and vehicle protection
24-hour parking guard: Monitor after the engine is turned off through built-in batteries or power supply, and record events such as scratches and collisions.
Anti-theft function: Some models integrate GPS positioning to track stolen vehicles.
4. Multi-function extended use
Travel record: Take pictures of the scenery or adventure process along the way during a self-driving tour as a souvenir.
Home monitoring/DV shooting: Temporarily serve as a home security camera or life recording device.
5. Emergency recording and legal protection
Natural disasters or emergencies: Record extreme situations such as heavy rain and mudslides to provide a basis for subsequent processing.
Legal evidence: In major accidents, videos can be used as key evidence for sentencing or compensation.
Other practical functions Loop recording and automatic overwriting: Save storage space and ensure continuous recording.
Night vision and high-definition picture quality: Starlight night vision technology ensures clear pictures at night. Voice control and mobile phone interconnection: Improve the convenience of operation.
