This actually refers to line 33 onwards. Sorry for the mistake.

Ended up moving WIFI setup here for it not to be away from Select camera model.
Select camera model had to be moved to a separate file to be able to be acessed from app_httpd.cpp

// Enter your WiFi credentials (replace ******** for the proper values)
// ===========================
#define WIFI_SSID "********"
#define WIFI_PASSWORD "********"
