I live on a campus in Washington State (at a public/state-funded school) and am interested in recording video (no audio) 24/7 in my dorm room without explicitly informing people who come in. I'm not sure if it's relevant but my dorm is paid for in full by a university scholarship.
All the information I could find about recording video in my own house (dorm) said that it was legal, except for areas with a higher expectation of privacy (bathrooms, bedrooms, etc).
I thought all hope was lost but then I came across a case where a person was recorded while using a living room as her bedroom. The judge ruled that even though the room was usually one of the most public rooms in a house, it was being used as a bedroom and therefore was subject to higher expectations of privacy.
I was wondering if this works the other way as well. It is true that my dorm does have a bed in it and it is where I sleep. However, when guests are over, it is not being used as a bedroom, rather a social area. Is this enough to get away without informing anyone?
