What is a critical aspect of ensuring effective surveillance at the border?

Employing multiple surveillance technologies is critical for ensuring effective surveillance at the border for several reasons. First, different technologies provide various advantages, such as the ability to cover large areas, detect movement more accurately, or operate under challenging conditions such as night or inclement weather. Combining radar, cameras, drones, and sensors can create a comprehensive picture of border activities, allowing for real-time monitoring and timely responses to potential threats or illegal crossings.

Additionally, the integration of varied technologies enhances the overall situational awareness of border patrol teams, enabling them to make informed decisions based on different data inputs. This multifaceted approach increases the likelihood of detecting illicit activities that might go unnoticed if relying solely on a single method. In contrast to other options, which either limit operational effectiveness or rely too heavily on one aspect of surveillance, employing multiple technologies provides a robust strategy to enhance border security and operational capability.
