FireBeetle 2 ESP32-S3 搭建外网可访问的网络摄像头（内网穿透）

本篇博文使用ESP32-S3搭建网络摄像头，相比较局域网摄像头，本篇博文将分享如何搭建外网可以访问的网络摄像头。
这主要是使用内网穿透技术，内网穿透是为了使具有某一个特定源 IP 地址和源端口号的数据包（这里指局域网摄像头）不被网络地址转换设备屏蔽而正确路由到内网主机。
主要流程分为两步：
1、先实现局域网访问网络摄像头；
2、在此基础，使用内网穿透的方式，搭建外网可访问的网络摄像头。
1、局域网摄像头
ESP32实现局域网摄像头的方式比较简单，驱动代码如下：#include "esp_camera.h"
#include <WiFi.h>

//
// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
//          Ensure ESP32 Wrover Module or other board with PSRAM is selected
//          Partial images will be transmitted if image exceeds buffer size
//
//          You must select partition scheme from the board menu that has at least 3MB APP space.
//          Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15
//          seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well

// ===================
// Select camera model
// ===================
//#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
// #define CAMERA_MODEL_ESP_EYE // Has PSRAM
//#define CAMERA_MODEL_ESP32S3_EYE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
//#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM

//#define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM

#include "camera_pins.h"
#include "DFRobot_AXP313A.h"

}

sensor_t * s = esp_camera_sensor_get();
// initial sensors are flipped vertically and colors are a bit saturated

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");

startCameraServer();

Serial.print("Camera Ready! Use 'http://");
Serial.print(WiFi.localIP());
Serial.println("' to connect");
}

void loop() {
// Do nothing. Everything is done in another task by the web server
delay(10000);
}
代码中有几点需要注意：
1、宏定义选择适配的摄像头模式。
// ===================
// Select camera model
// ===================
//#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
// #define CAMERA_MODEL_ESP_EYE // Has PSRAM
//#define CAMERA_MODEL_ESP32S3_EYE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
//#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM

#define CAMERA_MODEL_DFRobot_FireBeetle2_ESP32S3 // Has PSRAM
//#define CAMERA_MODEL_DFRobot_Romeo_ESP32S3 // Has PSRAM2、无线路由器SSID和密码要填写正确。
// ===========================
// Enter your WiFi credentials
// ===========================
const char* ssid = "";
const char* password = "";3、给摄像头供电
axp.enableCameraPower(axp.eOV2640);// 给摄像头供电4、板卡需要外接天线，否则可能无法连接路由器。
编译下载程序到板卡中，确保局域网访问网络摄像头可正常使用。
2、内网穿透网络摄像头
内网穿透我们使用花生壳这款软件提供的内网穿透服务。
https://img-blog.csdnimg.cn/064450fa4cca43c28b0287a59e008583.png在官网下载APP：https://hsk.oray.com/
下载安装完成后，在内网穿透服务点击新建映射，如下图所示：
https://img-blog.csdnimg.cn/b27080cf1c9d40dba91de5836722ec66.png填写新建映射的基本信息，请注意内网主机和内网端口是局域网摄像头的主机和端口（端口默认为80），如下图所示：
https://img-blog.csdnimg.cn/93e8681b24f34a2b8dc99ad571fe4173.png新建映射完成后，可以在APP看到新增的设备列表，如下图所示：https://img-blog.csdnimg.cn/ca2d312a550c4b98ac773680eab346dd.png复制访问网址，在浏览器中打开：http://2j90962r69.goho.co:47918/
即使不在同一个局域网内也可以正常访问摄像头啦。

终于知道我的esp 8266还有esp 32为什么连不上路由器了，原来是因为没有接天线信，谢谢大佬指点(*^o^*)
