[ESP8266/ESP32] FireBeetle 2 ESP32-S3 搭建外网可访问的网络摄像头(内网穿透)

[复制链接]
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:
  1. #include "esp_camera.h"
  2. #include <WiFi.h>
  3. //
  4. // WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
  5. //            Ensure ESP32 Wrover Module or other board with PSRAM is selected
  6. //            Partial images will be transmitted if image exceeds buffer size
  7. //
  8. //            You must select partition scheme from the board menu that has at least 3MB APP space.
  9. //            Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15
  10. //            seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well
  11. // ===================
  12. // Select camera model
  13. // ===================
  14. //#define CAMERA_MODEL_WROVER_KIT // Has PSRAM

代码中有几点需要注意:
1、宏定义选择适配的摄像头模式。
  1. // ===================
  2. // Select camera model
  3. // ===================
  4. //#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
  5. // #define CAMERA_MODEL_ESP_EYE // Has PSRAM
  6. //#define CAMERA_MODEL_ESP32S3_EYE // Has PSRAM
  7. //#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
  8. //#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM
  9. //#define CAMERA_MODEL_M5STACK_WIDE // Has PSRAM
  10. //#define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM
  11. //#define CAMERA_MODEL_M5STACK_UNITCAM // No PSRAM
  12. //#define CAMERA_MODEL_AI_THINKER // Has PSRAM
  13. //#define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM
  14. //#define CAMERA_MODEL_XIAO_ESP32S3 // Has PSRAM
  15. // ** Espressif Internal Boards **
  16. //#define CAMERA_MODEL_ESP32_CAM_BOARD
  17. //#define CAMERA_MODEL_ESP32S2_CAM_BOARD
  18. //#define CAMERA_MODEL_ESP32S3_CAM_LCD
  19. #define CAMERA_MODEL_DFRobot_FireBeetle2_ESP32S3 // Has PSRAM
  20. //#define CAMERA_MODEL_DFRobot_Romeo_ESP32S3 // Has PSRAM
复制代码
2、无线路由器SSID和密码要填写正确。
  1. // ===========================
  2. // Enter your WiFi credentials
  3. // ===========================
  4. const char* ssid = "";
  5. const char* password = "";
复制代码
3、给摄像头供电
  1. axp.enableCameraPower(axp.eOV2640);  // 给摄像头供电
复制代码
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。
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:
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:
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:
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^*)
