Hello there. I have a webcam which I do not use for visual communication or social chatting , so I want to put it into use as a security camera for my room. But there is an issue : I want to make sure that websites or applications which might use webcams connected to my PC do not use it , but webcam should be on for recording purpose. Anything like a firewall for this ?! P.S. I'm nearly Always connected to net , so I need a solution which doesn't suggest disconnecting from the net. Thanks in advance.
