To build this project, you need to follow the next steps. Follow the LAMP Server or the Hosting Server instructions depending on if you want to access the photos locally or from anywhere.<\/p>\n\n\n\n

1. Hosting Your PHP Application<\/h2>\n\n\n\n
The goal of this project is to have a local or cloud server to store and access your ESP32-CAM photos. <\/p>\n\n\n\n
1. Raspberry Pi local server<\/strong>:<\/p>\n\n\n\n
With a Raspberry Pi LAMP server<\/a>, you can access your images locally (as illustrated below).<\/p>\n\n\n
\n![\"ESP32-CAM](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2020\/06\/ESP32-CAM-Camera-Board-Send-Photo-Image-to-Raspberry-Pi-LAMP-Server-PHP-gallery-Script-Arduino.png?resize=900%2C806&quality=100&strip=all&ssl=1\")

- You can run a LAMP (Linux, Apache, MySQL, PHP) server<\/a> on a Raspberry Pi to access data in your local network<\/a>. Raspberry Pi LAMP Server: Local Linux server that you use to access your images locally.<\/li>\n<\/ul>\n\n\n\n
Setup Local RPi LAMP Server \u00bb<\/a><\/p>\n\n\n\n
2. Cloud server (Bluehost hosting solution)<\/strong><\/p>\n\n\n\n
You also can visualize the ESP32-CAM photos from anywhere in the world by accessing your own server + domain. Here’s a high level overview on how it works:<\/p>\n\n\n

<\/figure><\/div>\n\n\n- \n
- Bluehost (user-friendly with cPanel)<\/a>: free domain name when you sign up for the 3-year plan. I recommend choosing the unlimited websites option; Note that any hosting service that offers PHP will work with this tutorial. If you don’t have a hosting account, I recommend signing up for Bluehost<\/a>.<\/li>\n<\/ul>\n\n\n\n
Get Hosting and Domain Name with Bluehost \u00bb<\/a><\/p>\n\n\n\n
When buying a hosting account, you’ll also have to purchase a domain name. This is what makes this project interesting: you’ll be able to go your domain name (http:\/\/example.com) and see your ESP32-CAM photos. If you like our projects, you might consider signing up to Bluehost, because you’ll be supporting our work.<\/p>\n\n\n\n
HTTP POST Request Method<\/h2>\n\n\n\n
The Hypertext Transfer Protocol (HTTP) works as a request-response protocol between a client and server. Here\u2019s an example:<\/p>\n\n\n\n
- \n
- The ESP32 (client) submits an HTTP request to a Server (for example: local RPi Lamp Server or example.com);<\/li>\n\n\n\n
- The server returns a response to the ESP32 (client);<\/li>\n<\/ul>\n\n\n\n
HTTP POST<\/a><\/strong> is used to send data to a server to create\/update a resource. For example, publish an image to a server.<\/p>\n\n\n\n
POST \/upload.php HTTP\/1.1\nHost: example.com\nContent-Type: image\/jpeg<\/code><\/pre>\n\n\n\n2.1. Preparing Your .php<\/em> Files and uploads<\/em> Folder (Raspberry Pi LAMP Server)<\/h2>\n\n\n\n
This section prepares your .php<\/em> files and uploads<\/em> folder for your Raspberry Pi LAMP Server. If you’re using your own server + domain name, skip to the next section.<\/p>\n\n\n\n
Having a Raspberry Pi running Apache and PHP<\/a>, in the Raspberry Pi board terminal window navigate to the \/var\/www\/html\/<\/em> directory:<\/p>\n\n\n\n
pi@raspberrypi:~ $ cd \/var\/www\/html\/<\/code><\/pre>\n\n\n\nCreate a new folder called uploads<\/em>:<\/p>\n\n\n\n
pi@raspberrypi:\/var\/www\/html $ mkdir uploads\npi@raspberrypi:\/var\/www\/html $ ls\nuploads<\/code><\/pre>\n\n\n\nAt the moment, \/var\/www\/html<\/em> is owned by root, use the next commands to change to the pi user and give it all permissions so that you can save photos using a PHP script later on.<\/p>\n\n\n\n
sudo chown -R pi:pi \/var\/www\/html\nchmod -R 777 \/var\/www\/html\/<\/code><\/pre>\n\n\n\nFinally, create a new upload.php<\/em> file:<\/p>\n\n\n\n
pi@raspberrypi:\/var\/www\/html $ nano upload.php<\/code><\/pre>\n\n\n\nThis PHP script is responsible for receiving incoming images from the ESP32-CAM, rename the images with a timestamp and store them in the uploads <\/em>folder.

<\/a><\/p>\n\n\n\nArduino IDE<\/h3>\n\n\n\n
We\u2019ll program the ESP32-CAM<\/a> using Arduino IDE, so make sure you have the ESP32 add-on installed.<\/p>\n\n\n\n

Check the PHP URL<\/h3>\n\n\n\n
You should try to open the Raspberry Pi local IP address or your external example.com domain name, followed by \/upload.php<\/strong> that should return:<\/p>\n\n\n\n
Sorry, only JPG, JPEG, PNG & GIF files are allowed.Sorry, your file was not uploaded.<\/code><\/pre>\n\n\n\n![\"ESP32-CAM](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2020\/06\/ESP32-CAM-Camera-Board-Upload-Files-Image.png?resize=705%2C326&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nIf you see that message save your URL\/domain name and path, your server should be ready and you can continue with this guide.<\/p>\n\n\n\n
Additionally, try to access the \/gallery.php <\/strong>path. You should get something as shown below:<\/p>\n\n\n

<\/figure><\/div>\n\n\nESP32-CAM Code<\/h3>\n\n\n\n
If you’re using a local server without TLS\/SSL, or a cloud server that doesn’t support HTTPS, use the HTTP POST Request Code<\/a>.<\/p>\n\n\n\n
If you’re using a cloud server that requires HTTPS requests, use this code instead: HTTPS POST Request Code<\/a>.<\/p>\n\n\n\n

Inserting your Network Credentials, Camera, and Server Details<\/h4>\n\n\n\n
Before uploading the code, you need to insert your network credentials in the following variables:<\/p>\n\n\n\n
const char* ssid = \"REPLACE_WITH_YOUR_SSID\";\nconst char* password = \"REPLACE_WITH_YOUR_PASSWORD\";<\/code><\/pre>\n\n\n\nMake sure you select the right camera module. In this case, we\u2019re using the AI-THINKER Model. If you’re using another camera model, you can read this Guide ESP32-CAM Camera Boards: Pin and GPIOs Assignment<\/a>.<\/p>\n\n\n\n
Add your Raspberry Pi IP address or use the server domain name:<\/p>\n\n\n\n
String serverName = \"192.168.1.XXX\"; \/\/ REPLACE WITH YOUR Raspberry Pi IP ADDRESS\n\/\/String serverName = \"example.com\"; \/\/ OR REPLACE WITH YOUR DOMAIN NAME\nString serverPath = \"\/upload.php\"; \/\/ The default serverPath should be upload.php<\/code><\/pre>\n\n\n\nUpload Code to ESP32-CAM<\/h3>\n\n\n\n
Now you can upload the code to your ESP32-CAM board. Connect the ESP32-CAM board to your computer using an FTDI programmer<\/a>. <\/p>\n\n\n\n
Follow the next schematic diagram:<\/p>\n\n\n
