What are primarily used to control traffic flow and not in high security areas?

1. Security Cameras

2. Barrier Gates

3. Access Control Systems

4. Entry Devices

The correct answer is: Barrier Gates

Barrier gates are primarily utilized to control traffic flow, especially in parking facilities, toll booths, and similar environments where the regulation of vehicle entry and exit is necessary. Their primary function is to manage vehicles, allowing or restricting access based on specific criteria, such as payment or authorization. In contrast, security cameras, access control systems, and entry devices are typically utilized in high-security areas where monitoring, identification, and controlled access are critical. These systems are designed to provide surveillance, authorizations, and verification to ensure safety and security, which is not the primary function of barrier gates. Barrier gates focus more on physical traffic management rather than security monitoring or control, making them more suited for environments where the emphasis is on optimizing the flow of vehicles rather than securing a sensitive area.
