Brisket done in 5hrs

I don't know if anybody has seen this but would it be cooked properly, there was no talk of temps that i could hear, kids were my playing beside me!!
They didn't show it being sliced and they didn't show putting more charcoal in, didn't seem enough to me for a high temp for 5hrs.
