[ESP32] 安信可 ESP32-CAM 鏡頭實作 - 整合 Home Assistant

發表於

目的是有一個家用攝影機，偵測到物體移動後錄製，並在需要時回放觀看。
已有完整的開源專案https://github.com/s60sc/ESP32-CAM_MJPEG2SD，這篇記錄筆者一步步摸索踩坑的過程。

ESP32-CAM_MJPEG2SD

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。
將 #define INCLUDE_RTSP 設成 true，後面會用到，同時安裝好 ESP32-RTSPServer 套件。
選擇「工具」>「Partition Scheme」>「Minimal SPIFFS (…)」後開始編譯和燒錄。

Compilation error: #error “Need to install ESP32-RTSPServer library”

將專案移到 C:\Users\XXX\Documents\Arduino 底下即可。

燒錄完成後，執行會看到以下訊息

換一張 SD 卡試試，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。

後來發現還是與供電有關，電壓正常的話 SanDisk 64GB 也可以跑得起來。

表示供電不足，參考 ESP32-CAM Troubleshooting Guide: Most Common Problems Fixed。
換個麵包板，或是不要透過麵包板，直接接杜邦線試試。

初始化

透過 http://192.168.4.1 上的網頁選擇 wifi 路由器並輸入密碼。

設定好後，會開始從 GitHub 下載相關網頁檔案。

手動重啟並重新連上 wifi 路由器新指派的 IP 位址，就可以開啟鏡頭畫面查看。

筆者接著會將 AP 模式關閉，避免外部人士連進來，造成隱私洩漏。
選擇「Edit Config」>「Network」> 關掉「Allow simultaneous AP」> 記得「Save」

motionEye 遠端監控

先打開 RTSP 串流，選擇「Edit Config」>「Streaming」> 開啟「Enable RTSP Video」> 記得「Save」

重啟後查看，可以看到服務已啟動。

Home Assistant 安裝 motionEye 後，進入 motionEye 「添加攝像頭」> 選擇「網路攝影頭」，輸入 Log 看到的 RTSP 網址，以後便可透過 Home Assistant 查看。
