We can only sell the board camera. Means sell them without case
Take PZ0482 for example,pixim camera with 3.6mm lens, board camera only without case, it is USD 101.5, USD 5 less than the case one
. The size would be 38mm*38mm
So, to sum up, the case pixim camera only USD5 expensive than the board one for these three kinda pixim cameras.
