Я использовал этот код Arduino

void handleBmp()
{
if (!esp32cam::Camera.changeResolution(loRes)) {
Serial.println("SET-LO-RES FAIL");
}
auto frame = esp32cam::capture();
if (frame == nullptr) {
Serial.println("CAPTURE FAIL");
server.send(503, "", "");
return;

Serial.printf("CAPTURE OK %dx%d %db\n", frame->getWidth(), frame->getHeight(),
static_cast<int>(frame->size()));

}
WiFi.persistent(false);
WiFi.mode(WIFI_STA);

И код OpenCV
import urllib
import cv2
import numpy as np
url='http://192.168.8.100/cam-hi.jpg'
while True:
imgResp=urllib.request.urlopen(url)
imgNp=np.array(bytearray(imgResp.read()),dtype=np.uint8)
img=cv2.imdecode(imgNp,-1)
# all the opencv processing is done here
cv2.imshow('test',img)
if ord('q')==cv2.waitKey(10):
exit(0)
