The mount it ships with Foscam wireless IP cameras is too short requiring you to rotate the base which limits the field of rotation or you can mount your camera base at an angle which works but isn't optimal for all situations. I've created a replacement piece for the back half of the mount. There are two versions. The first has a slightly less than 90 degree angle and is designed for spring pressure. This is made to pressure fit to standard corner molding as shown in the picture. This lets me adjust the height at will which is nice when using it for meetings etc. The other has mounting holes. With the camera mounted right on a corner this design allows me to get maximum area coverage from my camera.
