Abstract: The present disclosure generally relates to systems and methods for ensuring proper installation of telecommunication equipment. A system in some embodiments has a mobile device equipped with an image sensor that is used to acquire one or more images of a telecommunication equipment component that has been installed. The mobile device may then evaluate at least one such image to determine whether the component has been correctly installed. In addition, the evaluation performed by the mobile device may also be used to ensure that a captured image of the component meets certain predefined criteria for helping the user to capture a quality image of the component for the purpose of proving that it has been correctly installed. Thus, it is more likely that the image will be later useful for establishing that the component has been correctly installed, thereby possibly preventing the need for a truck roll.
