Border surveillance is often more than what meets the eye. What appears to be a traffic barrel or a piece of litter could very well be a sophisticated surveillance device. The **EFF** is shedding light on this hidden world with a crucial update to their zine, "Surveillance Technology at the U.S.-Mexico Border." ### Identifying the Unseen The updated zine, the first since the second Trump administration, aims to equip individuals with the knowledge to identify the machinery of homeland security. It includes new models of surveillance towers, recently deployed military technology, and a gallery of disguised trail cameras and automated license plate readers.

"The **Battalion Search and Rescue** always carries the Electronic Frontier Foundation’s zine in our desert rig," says Holman. "We’re finding new surveillance all the time, and without a resource like that, we wouldn't know what the hell we're looking at.” The original version of the zine was primarily distributed to journalists, humanitarian aid workers, and immigrant advocates working in the borderlands. Now, the **EFF** has printed enough copies for its broader membership. ### Years of Research The zine is the result of extensive research, including a dozen trips to the border to identify surveillance towers and other tech installations. The **EFF** team attended border security conventions, filed public records requests, reviewed thousands of pages of documents, and analyzed satellite imagery. They also collaborated with local experts like geographer **Dugan Meyer**. The update is currently available in English, with a Spanish version expected later this year. The original Spanish edition has been reprinted. ### Further Resources For more information on the **EFF's** work on border technology, visit [here](https://www.eff.org/issues/border-surveillance-technology).
