I have already worked out how to use the Pi with a webcam and have even managed to link it to a port on the router and access from an external pc it over the internet. But I am very aware that it was probably insecure and open to anyone on the net. I want to ensure that only those who I grant access to can access the video stream over the internet. How do I do that? Are the changes I need to make on the Pi or in the router and if either what do I need to do?
Thanks in advance.
