Virtual Wall

The presence of surveillance may push border crossers to choose more remote and dangerous routes, thereby raising the risk of death.

The 'virtual wall' is a surveillance system deployed by the U.S. government along the U.S.-Mexico border, consisting of surveillance towers, sensors, and cameras, serving as a modern alternative to traditional physical fencing.

The United States has invested billions of dollars in border surveillance technology, deploying cameras, sensors, drones, and tower surveillance systems to construct a 'virtual wall.'

The network of surveillance towers along the U.S. border is often referred to as a 'virtual wall,' relying on cameras, radar, sensors, and AI image recognition technology to conduct round-the-clock automated monitoring of border areas.

Surveillance and recognition technologies can "see" people and record movement, but "seeing" does not equal "rescuing"; there is a gap between technological capability and policy objectives.

Over the past twenty-five years, the United States has invested billions of dollars along the southern border to build a "virtual wall" consisting of surveillance towers.

The official promise of the "virtual wall" system is to help detect and intercept border crossers while "saving lives."

The "virtual wall" along the U.S.-Mexico border refers to a border control approach that replaces or supplements physical barriers with surveillance towers, typically integrating cameras, radar, and AI image recognition capabilities.

The investigation found that individuals passed through areas covered by AI surveillance towers without being detected by the system, and subsequently died nearby with their remains going undiscovered for an extended period.

The investigation found that large numbers of border crossers died near surveillance installations, and the presence of surveillance towers did not result in border crossers being intercepted more safely.

The alert process of border surveillance systems is designed to trigger law enforcement responses (notifying border patrol to intercept), rather than to distinguish whether a target is in a medical emergency.

Border surveillance systems lack the capability to assess the physiological condition of detected individuals and cannot determine whether a stationary thermal imaging dot represents someone evading tracking or someone who has collapsed due to dehydration or heatstroke.

When migrants choose more remote and dangerous routes to evade surveillance, the intensification of technological surveillance may push them into more deadly situations.
