Overview
Front and rear 4K recording is the core of this dash cam, paired with Wi-Fi 6, GPS, ADAS alerts and a 128GB card in the box. It is built for continuous driving footage plus 24 hour parking surveillance.
- 4K front + 1080P rear recording
- Wi-Fi 6 with GPS and ADAS alerts
- 128GB card included, up to 512GB supported
- 24 hour parking mode with G-sensor lock
Who it's for
Daily drivers wanting clear front and rear footage with an included card and no extra shopping, plus optional parking monitoring. Less suited to anyone who ranks night video quality above all else.
What buyers say
From Amazon customer reviews.
Buyers consistently praise daytime footage as clear and detailed enough to read plates and signs, and several called installation and wire routing easier than expected. Wi-Fi 6 transfer speed to the app came up more than once as a real improvement. The recurring complaint is night performance: more than one reviewer said footage gets noticeably softer after dark even though it is still usable, and one buyer flagged that the app's full feature set needs a subscription, though a free tier exists.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sharp, detailed 4K daytime footage per multiple reviewers
- Wi-Fi 6 transfers clips to the app quickly
- 128GB card and mount included, nothing extra to buy
- Adhesive mount held securely through heat for some owners
- Night footage is noticeably softer than daytime
- App's fuller feature set sits behind a subscription
- Rear camera cable routing takes extra effort
