What technology is commonly employed by the Border Patrol to monitor borders?

The use of surveillance cameras and drones is a comprehensive approach employed by the Border Patrol to monitor borders effectively. Surveillance cameras are strategically positioned to provide real-time footage of specific areas, allowing for instant monitoring and quick responses to any suspicious activities. Drones add another layer of capability by offering aerial perspectives and the ability to cover vast areas quickly, which enhances situational awareness and enables agents to track movements along the border more efficiently.

This combination of technologies ensures that Border Patrol can gather vital intelligence and maintain constant vigilance, addressing the complexities of border enforcement. Unlike the other options, which are limited in their scope or methods, the integration of both surveillance cameras and drones creates a more robust and responsive monitoring system, essential for effective border security operations.
