Whittaker, from Wolverhampton, nearby, made a spectacular entrance while he was dancing in front of the pyrotechnics when she was accompanied by a choir, but was met with tunes.
The 2020 Olympic silver medalist seemed a little surprised at the reaction of the crowd.
Most observers were 34 years old, winning the first fight in Saudi Arabia, but it was Whittaker who started net, with a clear and precise punch.
England striker Marcus Rashford and UFC star Leon Edwards watched Whittaker – with his nickname “The Surgeon” engraved on his shorts – landed properly halfway.
He put it on Cameron and another right connecting while the legs of the sheffield fighter soaked and was held by the lower rope.
Referee Howard Foster saw enough and jumped. There were no real Cameron demonstrations.
After his verbal attack against Smith, Whittaker heard his hands while more hoots resounded in the arena, although he shared an embrace with Cameron and his team a little later.
Whittaker's stock dropped after his draw in Saudi Arabia. He left this fight in a wheelchair and was accused of leaving certain fans.
But he rebounded in style in his first fight under the respected coach Andy Lee, who defended the emotion of his boxer.
“No one can understand what this man has experienced in the past six months,” said Lee.
“The fact that he stands right here in the ring tonight, few people could bear what he experienced. His emotions are required to get carried away.”
