A swing gate barrier is a type of gate system used for controlling pedestrian access to a secured area. It consists of one or two gate panels that swing open to allow passage when authorized and close to restrict access. Swing gate barriers are commonly used in various settings, including public transportation areas, office buildings, stadiums, and other facilities where controlled access is required. https://www.novusapl.com/Advancing-Entrance-Security-Through-Automated-Technology.php
