The dashcam is used to record all images in the forward direction during driving, mainly for effective evidence collection in case of traffic accidents. As it is primarily used for accident evidence collection, the dashcam generally uses a storage card for recording. Depending on the pixel size and the memory space of the configured storage card, the recording time can vary from a few hours to several tens of hours. The dashcam adopts a loop recording method, automatically overwriting previous recording data when the storage is full.

Due to the frequent occurrence of traffic accidents and the high number of vehicles in many cities, the market for dashcams is booming. Many companies specializing in security have shifted their focus to dashcams. Below are a few dashcam solution companies for reference:
