...then you may not need an update. The old engineering adage applies:
Occasionally, a firmware update unlocks capabilities that were dormant in the hardware or adds new shooting modes that were not ready for the initial launch.
However, if you are struggling with SD card errors, the date resetting to 2016 every time you turn the car off, or corrupted video files, a is the single most effective solution.
Note down the version number and the date. If your version ends with 20210101 (early 2021) and you see a version like V2.0.4 from 2024 available online, you are significantly outdated.
Updates sometimes tweak the bitrate or exposure algorithms, resulting in clearer night vision or better license plate capture in high-contrast lighting conditions.
