What common method does the Border Patrol use to detect illegal crossings?

Utilizing surveillance technology such as cameras and sensors is a common method used by the Border Patrol to detect illegal crossings. This approach allows for real-time monitoring of the border area, enabling agents to respond quickly to any suspicious activity. Surveillance technology can include a variety of tools, such as infrared cameras, motion sensors, and drones, which enhance the ability to cover vast and often remote areas that may be difficult to patrol on foot or by vehicle.

This method is particularly effective because it can operate continuously without the manpower constraints that come with conducting physical checks, and it helps to identify potential illegal crossings before they escalate. By leveraging advanced technology, Border Patrol agents can gather valuable intelligence on crossing patterns and adjust their strategies accordingly, enhancing their overall effectiveness in securing the border.
