la camera envoie un flux video en wifi...eventuellement avec Motioneye (sur linux) on peut ajouter des fonction de detection mouvement/face etc...  mais c'est sur linux et complexe.

==== Esp8266 page web controle ====
Voir part 1 : https://randomnerdtutorials.com/esp8266-web-server/

  - Dans arduino IDE ajouter http://arduino.esp8266.com/stable/package_esp8266com_index.json  dans fichiers /preferences
  - Ensuite dans outils/Gerer les bibliotheque ajouter ESP8266
  - choisir Outils/type de carte : LOLIN(WEMOS) D1 D2 Mini
  - Et utiliser le code fourni sur la page en mettant votre ssid et mdp de votre wifi...

Attention les GPIO du WEMOS D1 sont pas les meme que les numero de pins : voir Pinout diagram ici : https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/
