The Department of Homeland Security has announced plans to expand its border surveillance tower network from 830 to 2,300 towers by 2034, investing $1 billion in advanced AI-enabled monitoring systems that could intensify privacy risks for border communities.
- Surveillance towers to nearly triple by 2034.
- $1 billion funding from 2025 One Big Beautiful Act.
- Expanded tech uses AI, radar, and infrared systems.
What happened
The Department of Homeland Security's Customs and Border Protection (CBP) plans to expand the Integrated Surveillance Tower (IST) program dramatically. This initiative will increase the number of surveillance towers along US borders from the existing 830 to approximately 2,300 by 2034. This expansion is supported by $1 billion in funding allocated under the 2025 One Big Beautiful Act, a significant federal spending and tax law.
The IST program relies on advanced autonomous towers equipped with AI-driven systems that include radar, thermal infrared, and optical sensors to monitor foot traffic, vehicles, and broader border areas over long distances. Existing towers will be upgraded with these autonomous capabilities, and new installations will extend coverage to residential neighborhoods and border communities, raising privacy and civil rights concerns.
Why it matters
This rapid scaling of border surveillance infrastructure represents a significant intensification in government monitoring of border areas, affecting individuals in towns, homes, and public spaces near the border. The technology surveils people indiscriminately, potentially violating privacy and civil liberties. Beyond towers, the border security apparatus includes drones, aerostats, ground sensors, game cameras, and license plate readers, creating a vast digital surveillance network.
The privacy risks are compounded by the deployment of similar technologies by state and local law enforcement and governments on the Mexican side of the border. Civil rights organizations emphasize the threats posed by this extensive surveillance, which can impact all those who live, work, or travel through these regions. Such systems may also contribute to broader concerns over biometric data collection and automated monitoring without sufficient transparency or oversight.
What to watch next
Attention will focus on how local communities and city governments respond to new surveillance tower proposals, such as the Anduril Industries tower planned for San Clemente, California. Public permitting processes and legal challenges are likely to become important battlegrounds for privacy advocates seeking to limit intrusive monitoring.
Observers should also track DHS’s technological upgrades and expansion activities over the coming years, along with advocacy efforts aiming to restrict or regulate the use of AI-based surveillance at the border. Ongoing transparency initiatives and mapping projects by civil rights groups will continue to shed light on the scope and nature of border security surveillance, influencing policy debates and public awareness.
