 目的是有一個家用攝影機，隨時錄製，且可移動鏡頭，並在需要時回放觀看。
-已有完整的專案<https://github.com/s60sc/ESP32-CAM_MJPEG2SD>，這篇記錄筆者一步步摸索踩坑的過程。

-下載整個專案
+下載整個專案，解壓縮後如果後面有版號或 master 後輟，要拿掉，只保留 ESP32-CAM_MJPEG2SD 資料夾名稱，接著用 Arduino IDE 開啟專案內的 ino 檔。
+檢查下 appGlobals.h 預設是選擇 #define CAMERA_MODEL_AI_THINKER，因筆者使用的就是 AI-Thinker ESP32-CAM 所以可以不用調整。
+選擇「工具」>「Partition Scheme」>「Minimal SPIFFS (...)」後開始燒錄。
+![](/assets/esp32-cam-4mb.png)
+
+燒錄完成後，執行會看到以下訊息
+```

+認真！換一張 SD 卡就好，原本用的是 SanDisk 64GB，已格式化成 FAT32，換成另一張 ADATA 64GB 就奇蹟可以使用了。

-修改 appGlobals.h，保留 #define CAMERA_MODEL_AI_THINKER，註解掉 #define CAMERA_MODEL_ESP32_S3_CAM
