When you have a webcam, or any other sort of security camera that goes through the internet, it would be in your best interest to have a password to access the same. Why is this? To put it simply, webcams and security cams before being viewed by the other source are first placed in a sort of online depository, where users may access the same provided they know how to connect to the same. Therefore even if a person does not have a direct link to your webcam, he may actually go to this depository and access the links there. Now of course there are thousands of links to different cameras, but he could use search words, and this stranger might stumble upon our webcam during more private moments.
Freaky? Don’t believe me? Try it for yourselves.
1) Go to the google search page
2) type inurl:/view/index.shtml in the browser
Now you will be in a page among others with different links with little or no details, those are the url's of webcams all over the world. Think of this area as a depot where all webcam feeds pass through, if the webcam doesn't have a password, you could probably view it through here. Security cams can be found in this depot as well, so you might see into some traffic cams, security cams in schools, etc. You can make your searches more specific as well.
