White, who will be dancing with Kym Johnson, explained that it is completely different to having cameras on him as an actor.
"I don't know if I'll ever be comfortable with the cameras there for the entirety of rehearsal," he told ET Online.
"Yeah, a camera with a great script and 'action' and 'cut' is wonderful, but when you have a camera there capturing your missteps and your frustrations, honestly sometimes you just want to punch the camera."
White warned fans that he is unlikely to include any moves from his Family Matters character Steve Urkel but added: "If there's any way I can evoke some nostalgia and just have fun with the crowd - that's going to happen."
White's competitor Jack Wagner recently claimed that he "will do anything" to win Dancing with the Stars, which premieres on Monday at 8/7c on ABC.
