The camera is only one part of the setup
A dash cam needs a safe mount, sensible cable route, suitable memory card and clear understanding of how footage is stored. Do not buy only by resolution.
Check the memory card rating
Dash cams write repeatedly and can run warm. Check endurance-card guidance, supported capacity and formatting requirements for the specific model.
Check fitting and privacy
Avoid blocking view, controls or airbags. Understand audio recording, parking mode, power drain and how footage is shared before installation.
Use UK Shortlists next
Use the installation and memory-card checklists before comparing dash-cam products.
