I had a run-in with a version of this issue in Pennsylvania. In PA, the homeowner does not have to disclose the use of spy cameras even to their spouse (co-owner.) The use of the camera becomes illegal if the courts determined that the spy camera was being used for self-gratification purposes. The cost to litigate was estimated to run between $40-50K (with no guarantees, of course.) Use Google images to check out 'spy cameras.' It's disgusting the lengths some people will go to serve their mental illness.
