Nothing in this Act shall be construed to impair the power of a county or municipality, including home rule units, to enforce the provisions of this Act or to license, regulate, suppress, or prohibit resale dealers, provided that any such actions are no less restrictive than required by this Act. This Section is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of the powers and functions exercised by the State. Such local licensing regulation may include the requirement to install, operate, and maintain a video camera surveillance system capable of recording clear and unobstructed photographic representations of the resale dealer’s customers. Such videotape recording may be subject to inspection by the appropriate law enforcement official.
