My Oly C4000 cams are sitting on a thin piece of wood at the top of my window for my views from the inside. In order to get the proper view angle, I have to shim up the fronts, etc.
I came across these $4 mini-mounts on EBay that might prove useful to others. They stand 2.5" tall and have 3 mounting holes in the base.
I ordered on the 2nd and they came today (15th) from Hong Kong with free shipping.
