Cameroon were handed a wake-up called ahead of the FIFA World Cup after succumbing to a 2-1 friendly defeat to Paraguay.
Thursday's match in Austria was the first of three warm-up games for Volker Finke's men before the tournament in Brazil, which starts next month.
However, Cameroon - who missed a late penalty - were left in no doubt as to the difficulty they will face in South America, as goals in each half from Oscar Romero and Roque Santa Cruz ensured victory for Victor Genes' men.
With Finke yet to trim his squad down to the maximum size of 23, several players with limited experience were handed the opportunity to shine.
But they were on the back-foot from the off as Romero opened the scoring with a composed finish inside four minutes.
Santa Cruz swept home the second with just over 20 minutes remaining, before Eric Maxim Choupo-Moting halved the deficit
