"A cheap dash cam with real 5GHz WiFi, but its '4K' resolution is mostly marketing."
The '4K resolution' refers to the video's pixel dimensions, not its actual clarity. The cheap sensor and lens will produce footage that is technically 4K but will struggle to capture fine details like license plates, especially in motion or at night.
This is for a buyer on a strict budget who needs a basic, working camera out of the box and values fast WiFi for pulling occasional clips. The screenless design is suitable for those wanting a discreet installation who are comfortable using a phone app for all controls.
Anyone who genuinely needs clear video evidence for insurance claims should spend more on a unit with a specified Sony STARVIS sensor. Users who require a functional parking mode must factor in the additional cost and installation of a hardwire kit.
