Blackbox Dash Cam Buying Guide

It is an in-car camera that continuously records short video segments and can preserve a clip when its impact sensor detects an event.

Only if the model supports parking mode and has a compatible source of constant power, such as an approved hardwire or battery solution.

Loop recording overwrites the oldest ordinary files when storage fills. Locked or event files are normally protected, but you should copy important footage promptly.

It can be useful when you want evidence of rear impacts or events behind the vehicle. It also requires more cable routing and storage bandwidth than a front-only camera.
