Dash cams with supercapacitors are more resistant to heat-related damage and are generally recommended for hot climates.

How do I view footage from my dash cam 4K front and rear?

You can view footage in several ways: directly on a built-in screen if available, like on REDTIGER models, via a smartphone app connected over Wi-Fi, or by removing the SD card and inserting it into a computer.

What should I do if my dash cam footage is corrupted?

If your footage is corrupted, it often indicates an issue with the SD card. Try formatting the card within the dash cam.

If the problem persists, replace the SD card with a new, high-endurance model.

Regularly formatting the card can help prevent corruption.

Are there any specific dash cam brands known for reliability in 4K front and rear setups?

Yes, brands like VIOFO, BlackVue, Thinkware, and Garmin are highly regarded for their reliability and performance in the 4K front and rear dash cam segment. REDTIGER offers a more budget-friendly option with solid features.
