ESP32-CAM remote image access via FTP. Take pictures with ESP32 and upload it via FTP making it accessible for the outisde network.
More information can be found on their comprehensive Docs. But Basically:
- Download and install official Microsoft Visual Studio Code. PlatformIO IDE is built on top of it
- Open VSCode Package Manager
- Search for official
- Install PlatformIO IDE.
ESP32-CAM does not have a built-in UART/USB converter, therefore you will need one.
- TX goes to RX;
- RX goes to TX;
- Power the board while keeping
- You can now release it and upload your code;
- This board has an AMS1117 voltage regulator which "sleep" current is around
6mA, this is quite a lot if you plan to have your board running on batteries.
- TODO! find an alternative with the same package.
Free Website Hosting
There're plenty of tutorials and examples on how to run the video streming or pictures on your local network while the ESP32 acts as a webserver.
The idea behind this project is to
uploadthe picture via FTP making it available on an URL something like:
This way you don't need to overload the ESP32, your network remains secure, not open to the world, no port forwarding.
For this example I uploaded the GitHub Octocat to my 000Webhost hosted webiste, the file is avalable under:
ftp.OpenConnection(); // Create the new file and send the image ftp.InitFile("Type I"); ftp.ChangeWorkDir("/public_html/zyro/gallery_gen/"); ftp.NewFile("octocat.jpg"); ftp.WriteData( octocat_pic, sizeof(octocat_pic) ); ftp.CloseFile(); ftp.CloseConnection();
- Your FTP details can be found on the 000webhost control panel once logged on click your site then details.
- This is a Bonus, as you may want to add it to your altomation project, you can use
Blynk Image Gallery Widgetand just supply it with the URL used by ESP32 from the hardware.
// Take a picture and add a time tag to it; take_picture( "my_picture_201906170521" ); upload_FTPpicture(); // And by changing it on Blynk from the hardware will reflect on the App Blynk.setProperty(VX, "url", 1, "https://mywebsite/something/my_picture_201906170521.jpg");
Another alternative is to send the image via MQTT(???) using cloud brokers as CloudMQTT and have the Node-RED subscribed to that topic and saving it to the database and serving the file locally.
This is a topic for another project, but can be seen briefly here
