The security barrier in a store with alarm and security technology typically consists of sensors placed at entry and exit points. These sensors detect when an item with a security tag passes through them without being deactivated at the checkout. When this happens, the sensors trigger an alarm to alert store staff of a potential theft. Additionally, the security tags on items are usually deactivated at the checkout counter using a special device, allowing customers to leave the store without setting off the alarm. **
