Enganamouit - celebrating her birthday - had a hand in all the goals as the west Africans enjoyed a perfect opening to their FIFA Women’s World Cup™ odyssey.
After a low-key opening half-hour, Enganamouit started a move which resulted in a goal for Madeleine Ngono Mani.
Just two minutes later Enganamouit received a long ball forward and beat goalkeeper Berruz with a low shot on her left
Little changed after the interval with Cameroon remaining stronger, quicker, and better organised.
The yellow-haired Enganamouit then brought about a red card for Ecuador captain Ligia Moreira, following a last-defender foul midway through the second period.
It was little surprise when the same player scored again following a neat pass from Gabrielle Onguene.
Another penalty was awarded following a handball from substitute Katherine Ortiz and duly scored by Onguene, before a third spot-kick scored in injury time by the heroine of the day, Enganamouit.
