Motion Detection Alarm System in Python 

i'm also getting same error

How do u add python code into bulb?

​There are Python libraries for smart bulbs. You connect to the bulb over wi-fi specifying it's IP address​ in Python code.@@alertsByJarvis

me too

Agree +1

Bro first install in cmd

​@@shenzo00ffbro source code available ? Can u share the link

Same problem here --> frame = imutils.resize(frame, width=500)

Figured it out. Tabbing error. Duh!

@@kevinflanigan8653 Very old newbie wondering what tab position should be?

@@jamesfraser7394 I believe my problem was that I had the "key_pressed = cv2.waitKey(30)" statement and the two subsequent "if statements" indented too far to the right. Had pull the group back by one tab. I hope that helps.

Hi there That's because your camera won't turn on, so there's no picture Try to change this cap = cv2.VideoCapture(0, cv2.CAP_DSHOW) for this cap = cv2.VideoCapture(0) I hope it helped you

I'm sure it's not opening the cam on my MacBook so no image.
