Using opencv-python package, the following piece of code momentarily captures the webcam information and saves the image in the directory specified. Note: The webcam indicator does light up for a fraction of second. I am not sure how that can be avoided as of now.

import cv2
webcam = cv2.VideoCapture(1) # Number which capture webcam in my machine
# try either VideoCapture(0) or (1) based on your camera availability
# in my desktop it works with (1)
check, frame = webcam.read()
cv2.imwrite(filename=r'<Your Directory>\saved_img.jpg', img=frame)
webcam.release()

This piece of code can be written in a bat file and you can trigger this for what ever event you are looking for (like startup security)
