The herein described invention is a camera mounting system where the user can safely install a camera high in a tree without having to leave the ground. The camera mounting system is comprised of a tree attachment, ball mount, and camera mount. The system is installed by using an extension pole with releasable capture means for installation and removal of the system. This system is also comprised of a multi-mount adapter, which allows a user to install multiple wire connected mounted components on one tree attachment, or in different elevated positions. Once installed, a camera can be accurately aimed by using a laser attachment and standard laser pen light. This system is further comprised of a saw attachment, which can be used to clear branches from the installation area of the tree being utilized.

A two-piece mounting system for a trail camera has a support with a fitting that is placed high in a tree on a tree branch. The support with an auger anchor is driven into the tree branch with an extension pole equipped with a companion fitting. The auger has a releasable spring-loaded turn-to-lock capture means to capture and hold a utility bar. The utility bar, like the auger support, is placed and attached to the support with the extension pole. The utility bar receives a universal camera mount attached to the bar through a swivel. The camera mount and swivel have an adjustment bar that has a fitting that can be received by the extension pole fitting, so once placed in the tree, the camera angle can be adjusted.
