The Camera Man is a crew that was hired to follows the everyday workings of Dunder Mifflin employees. Because of this, the camera crew is an acknowledged part of the show, breaking the fourth wall. The crew is rarely talked about and only occasionally seen in the show, but they are talked to whenever an office member is being interviewed.
The camera man sometimes plays integral parts in the show. For instance, when he shows Pam that Dwight and Angela have a relationship. This example shows us that the Camera Man has some stake in what happens in the office. Also, in the episode "Branch Wars ," when Jim is hiding from Karen in a car, the Camera Man is responsible for getting Jim caught, prompting Jim to mouth the words "Come on, man!" to him.
The cameraman has spoken once in a deleted scene of "The Surplus" where Andy is cleaning his shoe and the cameraman says “Mose” to bring his attention to Mose, who is standing in the background watching him.
Characters who are not part of the main cast sometimes react in surprise to the camera crew (for example, in the episode "Money ", Michael's other boss thinks they are a crew documenting the exploitation of workers). Sometimes people ignore the cameras along with everyone else (as in numerous sales calls where the customer is seemingly not confused by the presence of a camera crew).
