Uncomment the camera model that you are using. In the code, three camera models are defined. One is the main code file for camera and motors, and the other three codes are for web page, camera index, and camera pins.īegin the program by including header files and selecting the right camera model. This ESP32 Surveillance Camera has a total of four code files that are attached at the end of the project and also can be downloaded from here. #NODEMCU ARDUINO CAMERA INSTALL#In Boards Manager search for ESP32 and install the “ESP32 by Espressif Systems“. Now copy the below link and paste it into the “Additional Board Manager URLs” field, as shown in the image below. To install the ESP32 board in your Arduino IDE, go to File> Preferences For that, we have to install the ESP32 add-on on Arduino IDE. We will program the ESP32-CAM using Arduino IDE. This is how my surveillance robot looks like: We used a battery to power the motor drive module and ESP32-CAM. We built a robot by using a ready-made robot chassis, wheels, and DC motors. When GPIO 0 is connected to GND, the ESP32 is in flashing mode. IO0 determines whether the ESP32 is in flashing mode or not. Note: Before uploading the code, connect the IO0 to the ground. Module pins are connected to IO4, IO2, IO14, and IO15 pins of ESP32. Two DC motors are connected to ESP32 through the L293D module. Tx of and Rx of ESP32 is connected with Rx and Tx of the FTDI board. VCC and GND pin of ESP32 is connected with the VCC and GND pin of the FTDI board. The web page will also have buttons to move the car in Left, Right, Forward and reverse directions as shown in the image above.Īlso, download and install the Arduino IDE to upload the into ESP32.Īll the connections for ESP32- Surveillance Camera is given below:ĮSP32-CAM doesn’t have a USB connector, so you need an FTDI board to upload the code into ESP32-CAM. Here HTTP communication protocol will be used to receive video streaming from the OV2640 camera over the web browser. MicroSD card slot can be used to store images taken from the camera. The AI-Thinker ESP32-CAM module comes with an ESP32-S chip, a very small size OV2640 camera and a microSD card slot.
