There is one camera you shoot where a guy that’s in the garage will come out, walk around the outside to the front of the garage, then come back around. Either that or the guy that’s actually closest to it will go inside and upstairs to check. Sounds shouldn’t be penetrating walls like that. Not shot cameras at least.
eta: off-topic, bu this also happens at the church in Sap. Shoot a camera on the side of the building and one of the church dudes near the staircase will hear it or get panicked.
