Not able to connect to IP Camera on OpenCV Video Capture.!

I am using OpenCV in my python script to open the camera for facedetection. Using the below line to connect to IP Camera using the IP address but its not working here on Python Anywhere.

stream = cv2.VideoCapture('')

But FYI, it is working fine both when I am accessing the URL through my browser or when I am triggering the pythron script on my local cmd. Please help me to run the camera through the IP as it is the most crucial part of my project.

You have a free account. Free accounts can only connect to a whitelist of sites and only using htpp(s). Only sites that have a publicly documented API are eligible for the whitelist.

But are you sure, this is the issue, what if it still not get solved if i take the paid plan? isnt there any free trial for just 1 day to try the paid features so that i can be sure of switching to the paid plan

We refund unhappy clients up to 30 days after the upgrade.

ok in that case i can consider going for it
