NEXTBASE 64GB SD CARD: With a capacity of 64GB, the Nextbase microSD card will record up to 8 hours of HD footage before the dash cam overwrites the oldest recordings, or 4 hours if using a rear-view module. This provides you with enough capacity to capture any incident and ensure you have the evidence you need. Includes an SD card adapter for easy upload of the files on to your computer. DASH CAM MODEL COMPATIBILITY: Our 64GB micro SD card is compatible with Series 1 and Series 2 Nextbase dash cams. Compatible models include: 212, 312G, 312GW, 512G, 412GW, 512GW, 612GW, 222, 222X, 222XR, 322GW, 422GW, 522GW & 622GW. Older models are also compatible. Not suitable for the following Nextbase dash cam models: Ride, Duo, Mirror, 101, 202, 302G, 402G, 112, or 122. STAY PROTECTED ON THE ROAD: A Nextbase-specific micro SD memory card is required for your Nextbase dash cam so your footage on the road is recorded and securely stored in case of insurance claims. This means you always stay protected on the road and can have peace of mind whenever you drive. Ideal for capturing full HD, 1440p or 4K footage. HIGH WRITE SPEED: Nextbase has designed U3 micro SD cards with high continuous write speeds - faster than normal micro SD cards - that specifically fulfil the needs of our dash cams, which means you can be sure your dashcam will work perfectly when you need it most. If a lower capacity card is used, certain features will potentially not function properly, which can lead to issues such as freezing and missing footage. FORMAT FOR BEST PERFORMANCE: The Nextbase dash cam micro SD card should be formatted every 2-3 weeks to prolong its life and ensure your dashcam continues to loop record and run smoothly. This can be easily done via the dash cam menu settings. Without regular formatting and a compatible SD card, the card could become corrupted which would cause a failure of data writing.
