Which type of electronic defense is used in perimeter protection?

1. Magnetic contact switches

2. Alarm monitoring systems

3. Security cameras

4. Guard patrol systems

The correct answer is: Magnetic contact switches

Magnetic contact switches are commonly used in perimeter protection as they serve to create a security barrier that detects unauthorized entry. These switches are typically placed on doors, windows, and other access points where security breaches might occur. When a door or window is opened, the magnetic circuit is disrupted, triggering an alarm or alerting a monitoring system, which can prompt an immediate response to potential intrusions. While alarm monitoring systems, security cameras, and guard patrol systems all play important roles in overall security strategies, they operate in different ways. Alarm monitoring systems are broader and can incorporate various types of detection methods, including magnetic contact switches. Security cameras provide visual monitoring of the perimeter but do not directly prevent entry. Guard patrol systems rely on human intervention to ensure security, which, although effective, does not provide an immediate response to breaches like magnetic contact switches can. Thus, magnetic contact switches are specifically designed for perimeter protection, making them the correct choice in this context.
