Cardiff's relentless push for automatic promotion saw them seal their third win in four games at the City Stadium, as Campbell made it three goals from three appearances.
The 25-year-old former Sunderland striker now wants to continue by starting against Gus Poyet's Brighton, who drew 1-1 against Blackburn in their last league game.
"I hope there is more to come as I've not played much football the last year or so. It's going to take me a while to get up to speed with the rest of the players," Campbell told Wales Online.
"Hopefully a few more games will do me good. I've been playing for as much time as I can in every game. I'm trying to get as fit as possible.
"This is a massive chance for me in a team that is playing really well. I've not played football for the last couple of years so it's important for me to get myself back on track and hopefully I can do that at Cardiff."
