Question about Reolink Duo 2 LTE

The camera requires microSDHC or microSDXC cards up to 128 GB. I recommend a high-quality microSDXC card with a UHS-I U3 or V30 rating for reliable 4K recordings, e.g. SanDisk High Endurance or Samsung PRO Endurance.

Details:
- Official specification: microSD cards up to 128 GB are supported (microSDHC for ≤32 GB, microSDXC for 32-128 GB).
- Recommendation: Endurance cards (High Endurance) are ideal for frequent write cycles for surveillance videos. Look for U3/V30 classification for constant write speeds above 30 MB/s.
- Note: Only use branded cards - cheap products can lead to recording errors. The camera has no internal memory, the card is mandatory.
