Which Cameras can I use this tool on?

It was designed for the outdoor camera but the indoor camera has a similar mount that swivels.

Is the tool sturdy?

It is a solid plastic and will not bend. The amount of pressure needed to press the camera onto the mount is pretty minimal once the tool helps you center the mount head.

Do you make other tools or accessories for cameras?

We are experimenting with some boxes/cases that hold the camera and that can then be screwed into a tree or other surface with security screws. Let us know if you have any other ideas/solutions you would like to see.
