VIOFO Memory Card
Recommendation
(Sold Separately)

Dash cams require a memory card that can withstand heavy writing cycles.
A high-endurance card, designed especially for heavy use and
write-intensive applications, is extremely critical for dash cam recording.
Cheap cards are the main cause of most unexplainable recording issues,
have poor performance in non-stop writing endurance, and are less likely to
withstand harsh conditions. VIOFO industrial high endurance microSD cards,
optimized for dash cam recording, give greater assurances around
compatibility and long-life durability, greatly elevating your dashcam
owner experience.
