Make note that if you have certain Treadnet webcams, a hacker can access your feed by using your IP address in a certain URL string. This bypasses the login page and goes directly to the cam in a web browser:
From The Verge: “Last week, a blog called Console Cowboys exposed a security vulnerability in some models of Trendnet home security cameras. Following the instructions on the site, thousands of streaming personal IP cameras can be accessed. Links to the compromised feeds spread quickly on message boards like Reddit and 4chan, where the adolescent quest for the surreptitiously-viewed nipple kicked into high gear.”
Treadnet has supplied a patch for this issue.
