I would find useful a way to mount the cameras on a tripod. Also it would be nice to be able to fasten the metal base to a wall with a screw rather than with adhesive. Perhaps the easiest way would be add two holes to the metal base. A hole in the metal base for mounting to a wall using a screw. If it were counter sunk then a flat head screw could be used. Also 1/4-20 tapped hole on the edge of the metal base for mounting on a tripod. I added a 1/4-20 tapped hole to one of my metal bases.
