Certainly! Currently you'll recieve a SD card prepared by Momcozy for BM03. If the existing SD card capacity doesn't meet your expectations, you may replace it with a higher-capacity card.
For optimal performance, we recommend selecting an SD card that meets the V10 speed class standard. This ensures the monitor can efficiently record and access video and image data. This recommendation also applicable to the Baby monitor BM04 (withot SD card when you purchase).
