How much video detail do you need?
Compare actual recording resolution, frame rate, HDR and published sample footage. A higher pixel count alone does not guarantee readable plates in motion or darkness.

What to Look for in a Dash Cam Before You Buy
Prioritize readable footage, reliable storage and a safe installation. Extra features matter only when their power, subscription and accessory requirements fit your car.
Should you choose front, rear or cabin coverage?
Front-only is simpler. A rear channel documents following traffic; an infrared cabin channel can suit rideshare work but changes installation and storage needs.
How does parking mode receive power?
Read what the mode records and whether it needs hardwiring, OBD-II power or a separate battery. Low-voltage protection helps avoid excessive vehicle-battery drain.
Which memory card belongs in a dash cam?
Use a high-endurance card of the speed class and capacity named by the manufacturer. Continuous overwriting is harsher than ordinary phone or camera use.
Will the mount obstruct your view?
Choose a position permitted in your province, outside the driver's critical sightline, and route cables clear of controls and airbag deployment paths.
Which connected features carry conditions?
Check whether cloud backup, live view, LTE or alerts require a phone connection, separate module or subscription. Confirm app support for your phone before purchase.
Common questions
Questions before you buy
Is 4K necessary for a dash cam?
No. It can add detail, but bitrate, sensor, lens, exposure and motion all affect evidence quality.
Is Wi-Fi useful on a dash cam?
It makes settings and clip transfer easier, but it is not the same as internet connectivity or automatic cloud backup.
Should a dash cam have GPS?
GPS can add location, time and speed data. Decide whether you want that information embedded or recorded.
How often should a dash cam card be replaced?
There is no universal interval. Check card health, review recordings regularly and replace it when errors appear or the card maker's guidance calls for it.
