What size SD card for a REDTIGER dash cam?

Quick answer

For most REDTIGER dash cams a 128GB or 256GB high-endurance card is the practical size: the REDTIGER F17 4K 3CH Dash Cam (4K, 3 channel) keeps about 5 h 5 min on 128GB at a typical bitrate. The maximum supported size is in each model's manual.

How long does each REDTIGER model record?

Recording times use typical bitrates for each resolution (12 Mbps 1080p, 16 Mbps 2K, 20 Mbps 2.5K, 32 Mbps 4K, plus 10 Mbps per extra channel), not REDTIGER's own published figures, which vary by model and quality setting. Where a listing does not state the channel count, the model is treated as front only.

Frequently asked questions

What is the maximum SD card size for a REDTIGER dash cam?

It depends on the model. The supported maximum is printed in each REDTIGER manual and often in the product listing; current 4K models generally accept larger cards than older 1080p ones. A card larger than the stated maximum may not format or may record unreliably, so check the specific model before buying a 256GB or 512GB card.

Which SD card should I use in a REDTIGER dash cam?

Use a high-endurance microSD card from a major maker, rated for continuous video, in a size at or below the camera's maximum. Format it in the camera before first use and every few weeks after. Some makers sell their own branded cards; any quality high-endurance card of a supported size works the same way.

How long does a REDTIGER dash cam record on 128GB?

At typical bitrates, a 1080p front-only model records about 22 h 3 min on 128GB and a 4K front and rear model about 6 h 18 min. Your model's quality setting, codec and event-file reserve change the real figure; the table above lists each REDTIGER model we carry.
