+## Service AP
+
+After powering on and booting up the camera, it enters **AP mode**, which serves as a configuration mode for the camera. Essentially, it starts its own Wi-Fi network. The network name (SSID) is **ESP32_camera_UID**, where **UID** is the first three numbers from the **MCU ID**, serving as a unique identifier for the camera. The password for connecting to the AP is **12345678**. The camera's IP address is **192.168.0.1**. To configure the camera via **AP mode**, you need to connect to this IP address using a web browser: **http://192.168.0.1**. Alternatively, you can also use the **http://prusa-esp32cam.local** hostname (**mDNS**) instead of the IP Address.
+
+After establishing a successful connection, your computer might display a "**No Internet**" warning for the given network. **This is normal**.
+
+If you have set up a Wi-Fi network name (SSID) and password in the camera for it to connect to, then upon powering on, the camera will automatically connect to the configured Wi-Fi network and simultaneously activate AP mode for **5 minutes**. AP mode is always enabled after powering on and booting up the camera for **5 minutes**. The service Wi-Fi AP is **automatically deactivates** itself after **5 minutes** following each camera startup if no device is connected to the camera.
