An automatic boom barrier system is a physical security device commonly used in parking lots, toll booths, and restricted entry points to control the flow of vehicles. It consists of a horizontal bar or "boom" that blocks vehicular access until authorized.
Detection: The system incorporates various sensors such as loop detectors, infrared sensors, or proximity sensors to detect approaching vehicles.
Barrier Operation: Upon detecting an authorized vehicle, the boom barrier automatically raises to allow passage. Conversely, for unauthorized vehicles or when access is denied, the barrier remains closed. https://www.novusapl.com/Ultrafast-Boom-Barrier-NS-BS7-P416.php
