Buying a Dashcam: What to Decide Before You Choose

Front-only is simpler and covers the direction most drivers prioritize. Front-and-rear systems add evidence behind the vehicle but require extra wiring and storage.

Not always. Sensor performance, processing, lens, exposure and compression affect useful detail alongside resolution, especially at night.

Choose capacity based on channel count, resolution and the recording time you want before loop overwrite. Use a card type and capacity approved by the camera maker.

Choose it if unattended recording matters and you can install a supported power solution with battery protection. Review how each parking mode triggers and stores clips.
