The Brave Warriors stopped the five-time champions in their Group C qualifier at the Dobsonville Stadium in Johannesburg, South Africa.
The victory sent Namibia to the top of the group with five points, one more than second-placed Indomitable Lions in the three-team group.
Burundi , the other team in the group, have played two matches and have one point, giving Namibia a good chance of qualifying for Africa’s flagship football competition.
In-form Mamelodi Sundowns forward Peter Shalulile, who also netted in the 1-1 draw against the same opponent last week, opened the scoring in the 55th minute before Absalom Limbondi extended the lead in the 79th minute.
Turkey-based Vincent Aboubakar was on target for the Indomitable Lions deep into stoppage time but was not enough for Cameroon sparking Namibia coach Collin Benjamin into some excitement.
“This is a very sweet win against a strong Cameroon team. I congratulate my players for working hard to get maximum points today”, said the happy Namibia coach Benjamin.
The Cameroon coach Rigobert Song was disappointed insisting his players did not take advantage of their opportunities.
« We failed to take our chances and Namibia punished us”, the former international defender said after the game.
