Almost every dash cam produces acceptable footage in daylight. The ones worth buying are the ones that still resolve a number plate at dusk, in rain, and when the car in front is moving away from you.
What we looked for
- Plate legibility at speed in low light, which is the only test that really matters.
- Dynamic range entering and exiting tunnels and underground car parks.
- Parking mode behaviour and how it draws power without flattening the battery.
- Heat tolerance — cheap units routinely shut down on a hot windscreen.

The ranked picks, the side-by-side comparisons and the ones that did not make the cut are all in the video version of this test.
How to choose
Resolution numbers are close to meaningless on their own. A well-implemented 1440p sensor with good processing regularly outperforms a 4K unit with a cheap lens, because plate legibility depends on optics and bitrate rather than pixel count.
If you want parking surveillance, plan the power supply before you buy. Hardwiring with a voltage cut-off is the only approach that reliably protects your battery, and a camera with a supercapacitor rather than a lithium battery will survive summer heat far better.
Common questions
Do I need a rear camera as well?
Rear-end collisions are common and often disputed, so a two-channel system meaningfully improves your coverage. It also roughly doubles the installation work.
How long does footage stay on the card?
Most cameras loop-record and overwrite. Expect a few hours on a 64GB card at high bitrate, with incident clips locked separately. Use a high-endurance card, as standard cards fail quickly under continuous writing.
