The difference between 4G driving recorder and traditional driving recorder

The core function of the traditional driving recorder is the audio and video recording during driving, that is, video recording, recording, and taking pictures, which can be used as audio and video evidence for law enforcement claims in the event of an accident or touching porcelain. The main stage of its effect is during the driving process of the vehicle. In actual work and life, the stolen and scratched vehicles after the parking person leaves are the real headaches.
