You can use either of the two options below, both available from Dream RC. ⚠️ Important: Never power the ESP32-CAM from the 3.3V pin — always use the 5V pin for stable operation during programming and streaming. Using 3.3V can cause random resets and upload failures.1Add ESP32 Board Package to Arduino IDEOpen Arduino IDE → File → Preferences → Add this URL to Additional Boards Manager URLs:https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.jsonThen go to Tools → Board → Boards Manager → Search esp32 → Install esp32 by Espressif Systems.2Select the Correct Board & SettingsGo to Tools → Board → AI Thinker ESP32-CAM. Set partition scheme to Huge APP (3MB No OTA) for camera sketch. Select the correct COM port from your programmer.3Upload CameraWebServer ExampleGo to File → Examples → ESP32 → Camera → CameraWebServer. Fill in your WiFi name and password, select CAMERA_MODEL_AI_THINKER, then upload. Open Serial Monitor at 115200 to get the stream URL.⚙️ Arduino IDE Settings For ESP32-CAMARDUINO IDE → TOOLS MENU — EXACT SETTINGS FOR ESP32-CAMBoardAI Thinker ESP32-CAM ⚠️ Not ESP32 Dev Module!CPU Frequency240MHz (WiFi/BT)Flash ModeQIOFlash Size4MB (32Mb)Partition SchemeHuge APP (3MB No OTA) ← Required for cameraUpload Speed921600Core Debug LevelNone �� Streaming Tip: After upload, press the RESET button on the ESP32-CAM. Open Serial Monitor at 115200 baud — you will see the IP address. Type that IP in any browser on the same WiFi network to open the live stream page. �� PSRAM Tip: Make sure PSRAM is enabled in your sketch (psramInit()) for higher resolution streaming — the 4MB PSRAM is what allows UXGA resolution without crashing.�� Quick Start — WiFi Camera Stream ExampleThis example connects the ESP32-CAM to your WiFi and starts a live video stream accessible from any browser on the same network. ��ESP32-CAM WiFi Video Stream (CameraWebServer)// Go to: File → Examples → ESP32 → Camera → CameraWebServer // Then make these changes at the top of the file: // Step 1 — Select your camera model (uncomment this line only) #define CAMERA_MODEL_AI_THINKER // Step 2 — Enter your WiFi credentials const char* ssid = "Your_WiFi_Name"; const char* password = "Your_WiFi_Password"; // Step 3 — Upload, then open Serial Monitor at 115200 baud // You will see something like: // Camera Ready! Use 'http://192.168.1.X' to connect // Open that IP address in your browser to see the live stream!Open Serial Monitor at 115200 baud after upload to get the stream URL. Works in Chrome, Firefox, and Edge.❓ Frequently Asked Questions❓ Does the ESP32-CAM have a USB port for uploading code?No — the ESP32-CAM does not have a built-in USB port. You need a separate programmer board to upload code. Dream RC offers two options — the ESP32-CAM USB Type-C Upload Module and the ESP32-CAM Micro USB Code Upload Module. Both are linked below in the You Will Also Need section.❓ What resolution can the ESP32-CAM stream at?The ESP32-CAM can stream at multiple resolutions from QQVGA (160×120) all the way up to UXGA (1600×1200). For smooth live streaming over WiFi, SVGA (800×600) or VGA (640×480) is recommended. Higher resolutions like UXGA work better for still image capture.❓ Can the ESP32-CAM do face detection?Yes — the CameraWebServer example includes built-in face detection and face recognition features powered by the ESP32’s processing capability. Enable it from the camera stream web interface. Note that face recognition works best at lower resolutions like QVGA or VGA for real-time performance.❓ How do I save images to the microSD card?Format your microSD card as FAT32 and insert it into the slot. In your sketch include the SD_MMC.h library to initialize the card, then use the camera capture function to save JPEG images directly. Dream RC’s example sketches include a full SD card capture demo.❓ What is the ESP32-CAM price in Bangladesh?The ESP32-CAM WiFi Bluetooth Camera Module price in BD is 699 BDT from Dream RC — the best price in Bangladesh with genuine stock, fast delivery, and Cash on Delivery available nationwide.�� You Will Also Need & Related ProductsThe ESP32-CAM has no USB port — you need one of these programmer boards to upload code.
