How to Recognise a High-Quality Dash Cam

Useful detail comes from the sensor, lens, exposure, dynamic range, bitrate and compression working together. Resolution alone cannot guarantee readable moving plates.

It can capture more detail, but only if the imaging and encoding support it. A well-tuned lower-resolution camera may handle motion or low light more effectively than a weak 4K implementation.

Low light forces compromises between exposure and motion blur, while headlights can create extreme contrast. HDR and good tuning help, but no camera can recover detail that was never captured.

Yes. Higher bitrate can preserve more detail and reduce compression artefacts, though it also shortens recording time for a given memory card capacity.
