The video recorded from the surveillance system shall be retained for not less than 14 days. A license holder must post appropriate signage notifying individuals on the premises they are being recorded. On or before December 31, 2020, the Board shall adopt regulations relating to digital surveillance in consultation with the Baltimore Police Department.
