I have d-link style audio and video recorders running in my house which are recording constantly to hard drives.  The cameras are not hidden in that they are plainly visible, obviously cameras, and have a flashing light indicating they are on.  The cameras are not in and cannot see into the bathroom or bedroom, but are the the kitchen, living room, dining room, family room etc.

I have a girlfriend who does not live here but frequently stays over, and dog walker who has access to the house (which was the original reason for getting the cameras).  From reading through  it implies that all parties must consent to the recording, but doesn't go into detail what consent means (written, verbal, notarized).

My concern is:  in the case of a bad breakup, or the dog walker doing something illegal, or some other incident in the house, I would like to use the recordings in my defense.  What types of consent are needed to make this possible?  Does the fact that the cameras are visible imply consent from anyone remaining in the house?  Should I be posting signs?  Getting signatures from visitors?
