This tutorial shows how to set a static\/fixed IP address for your ESP32-CAM board. If you\u2019re running a web server or Wi-Fi client with your ESP32-CAM and every time you restart your board, it has a new IP address, you can follow this tutorial to assign a static\/fixed IP address.<\/p>\n\n\n\n

Static\/Fixed IP Address Sketch<\/h2>\n\n\n\n

To show you how to fix your ESP32-CAM IP address, we\u2019ll use the CameraWebServer Example<\/a> that comes with the Arduino IDE. <\/p>\n\n\n\n

By the end of our explanation you should be able to fix your IP address regardless of the web server or Wi-Fi project you\u2019re building.<\/p>\n\n\n\n

In your Arduino IDE, go to File <\/strong>> Examples <\/strong>> ESP32 <\/strong>> Camera <\/strong>> CameraWebServer<\/strong>.
Then, modify the code to fix the IP address as we\u2019ll explain.<\/p>\n\n\n\n

Setting ESP8266 Static IP Address<\/h2>\n\n\n\n

Before the setup()<\/span> and loop()<\/span> functions, define the following variables with your own static IP address and corresponding gateway IP address. <\/p>\n\n\n\n

By default, the next snippet assigns the IP address 192.168.1.184 that works in the gateway 192.168.1.1.<\/p>\n\n\n\n

\/\/ Set your Static IP address\nIPAddress local_IP(192, 168, 1, 184);\n\/\/ Set your Gateway IP address\nIPAddress gateway(192, 168, 1, 1);\nIPAddress subnet(255, 255, 0, 0);\nIPAddress primaryDNS(8, 8, 8, 8); \/\/optional\nIPAddress secondaryDNS(8, 8, 4, 4); \/\/optional<\/code><\/pre>\n\n\n\n
In the setup()<\/span>, you need to call the WiFi.config()<\/span> method to assign the configurations to your ESP32-CAM (before starting Wi-Fi).<\/p>\n\n\n\n
if(!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {\n  Serial.println(\"STA Failed to configure\");\n}\nWiFi.begin(ssid, password);<\/code><\/pre>\n\n\n\n
The primaryDNS<\/span> and secondaryDNS<\/span> parameters are optional and you can remove them.<\/p>\n\n\n\n
You can download the complete code for this project here<\/a>. It assigns the static IP address 192.168.1.184. You just need to insert your network credentials and the code will work straight away.<\/p>\n\n\n\n
Testing<\/h2>\n\n\n\n
After uploading the code to your board, open the Arduino IDE Serial Monitor at the baud rate 115200. Restart your ESP32-CAM board and the IP address defined earlier should be assigned to your board.<\/p>\n\n\n\n
\"ESP32-CAM<\/figure><\/div>\n\n\n\n
As you can see, it prints the IP address 192.168.1.184.<\/p>\n\n\n\n
Now, you can access that IP address on your local network to watch the video streaming web server<\/a>.<\/p>\n\n\n\n
Wrapping Up<\/h2>\n\n\n\n
In this tutorial, you\u2019ve learned how to set up a static IP address for your ESP32-CAM. You can use what you\u2019ve learned here in any of your ESP32-CAM sketches.<\/p>\n\n\n\n
