How to make a WiFi spy cmera

How to make a WiFi spy camera 
MATERIALS REQUIRED:
. ESP32 camera module
. Jumper wire
. 3.7v battery 1100mah 
. Tp-4056 charging module 
. Ftdi

CODING PROCESS:
After completing this given circuit write code in arduino ide. 

CODE :

Do this in arduino ide
const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";
Here change your ssid and password in the given below code
Serial.print("Camera Stream Ready! Go to: http://") whenthe code is completed here will be a link open it.

  IMPORTANT!!! 
   - Select Board "AI Thinker ESP32-CAM"
   - GPIO 0 must be connected to GND to upload a sketch
   - After connecting GPIO 0 to GND, press the ESP32-CAM on-board RESET button to put your board in flashing mode
