Surveillance Project V4

Mapping Surveillance Infrastructure in Los Angeles County

Behind every camera, every facial recognition system, every automated license plate reader, there is a vendor selling visibility as a product.

Building upon Electronic Frontier Foundation’s Atlas of Surveillance, our final project presents a critique of the ties between surveillance technology deployed by police departments and their vendors, who provide the equipment. We aim to establish how power and capital drive the intensification of surveillance, which increases the targeting, thus hypervisibility, of marginalized communities using automated technology – forming a feedback loop driven by data.

Using the Electronic Frontier Foundation’s Atlas of Surveillance as our starting point, we trace how vendors, dollars, and contracts structure the circulation of surveillance technologies in Los Angeles County. We move the focus from “which police department uses what tool” to the economic architecture that makes that infrastructure possible.

Privacy Dissolution

Surveillance technologies operate in what was traditionally known as "public" and "private" spaces, dissolving the boundary between the two. Information is now extracted even from the environment of your home.

Capital & Power

Behind every surveillance camera, every facial recognition system, every license plate reader, there are corporations profiting from your data. This project reveals the economic architecture.

Hypervisibility

Surveillance is not applied equally. Automated systems intensify the targeting of marginalized communities, creating feedback loops where data extraction leads to increased policing.

Contextual Integrity

As Helen Nissenbaum argues, privacy violations are defined by the lack of contextual integrity of data collection. Surveillance technologies routinely move data across contexts without consent.

Traceability

For Wendy Chun, "the degree of visibility, or more properly traceability, is the issue." The systems mapped here do not simply watch; they store, sort, and index.

Top Vendors

Surveillance is an industry. These vendors appear most frequently in our dataset.

    Data source: EFF Atlas of Surveillance, filtered to Los Angeles County.

    Most-Surveilled Cities

    These cities show the densest concentration of deployed systems.

      Counts represent distinct systems per city in the dataset.

      Network Visualization

      Each node represents either a vendor or a law enforcement agency. Edges connect vendors to the agencies they supply.

      How this visualization works

      What it shows: Vendors (colored nodes) function as central hubs in the graph, revealing how specific corporations dominate the market. Agencies (grey nodes) cluster around them, revealing infrastructural chokepoints. An “unknown” vendor in fact accounts for the highest portion of surveillance technology accounted for within the dataset. We chose to include the category “unknown” rather than deleting these from the dataset to mark this silence.

      Interaction: Drag nodes to disentangle the connections. Click a vendor node to display an alphabetical list of all law enforcement agencies currently contracting with them.

      Technical: A force-directed graph built with D3.js showing many-to-many relationships. Nodes are weighted according to their out-degree, meaning vendors providing technology to the most agencies appear larger.

      Geographic Distribution

      Each point marks a documented deployment of surveillance technology in Los Angeles County.

      How this visualization works

      What it shows: Each marker represents a surveillance system. Color indicates technology type. The map displays headquarters of specific law enforcement agencies rather than the full area of coverage.

      Technical: Maps were constructed using Python geopy library to add coordinates to the original dataset, visualized on Open Street Map via Leaflet.js.

      Growth Over Time

      Documented systems by year of implementation or first public record.

      How this visualization works

      How to interact: Hover for counts. Click a bar to see technology breakdown for that year.

      Technical: Dates extracted from source link metadata. The largest boom in surveillance technology use occurred in 2020, which correlates to physical distancing due to the COVID-19 pandemic and the Black Lives Matter uprising.

      Vendor Profiles

      Companies supplying surveillance technology to LA County law enforcement.

      Data Source & Availability: Vendor details (Founding year, Revenue, Descriptions) are sourced from public records, Crunchbase, and official company press releases. Some private equity-owned firms do not disclose financial data.

      About This Project

      Methodology & Data

      Our project is primarily based upon the Los Angeles County subsection of the Atlas of Surveillance dataset. Atlas of Surveillance uses "a combination of crowdsourcing, data journalism and public records reporting" to compile their repository. Although the dataset provided a significant base, we identified gaps that required data mining. Specifically, we have added coordinates for law enforcement agencies and vendors using the Python geopy library to locate them using GIS tools, and economic data when profiling vendors to give a sense of the profits they are garnering.

      We chose to include the category “unknown” rather than deleting these from the dataset to mark this silence, foregrounding that we do not always know who is watching us nor who is profiting from it. All data, including our altered dataset, is housed on GitHub for transparency.

      Critiques & Gaps

      Information in the original dataset relies on what is publicly available online. Like all datasets, it is shaped by what is missing, which in this case is likely informed by omissions and obfuscations of the public record by law enforcement agencies themselves. Location data displays headquarters of specific agencies rather than the full area of coverage. Were we to have that information, a heatmap might allow visitors to better understand where surveillance technologies are concentrated to make clearer the disproportionate targeting of minoritized communities.

      Meta-Surveillance & Theory

      This site incorporates a meta-critique via the custom counter at the top of the page. As Wendy Chun notes, "Online, one is not simply a spectator-citizen-commodity owner. Even when 'just viewing' or 'lurking,' one actively sends and receives data (all spectators are still visible—the degree of their visibility, or more properly their traceability, is the issue)." By turning ourselves and site visitors into the surveillants, we hope to raise questions about how being subjected to constant surveillance can naturalize carceral ideologies.

      Our theoretical framework draws heavily on Helen Nissenbaum’s context integrity—examining how privacy is violated not just by exposure but by inappropriate information flows—and Critical Data Studies to map the spatial and transactional relationships of control.

      Environmental Scan & Contribution

      Data-driven projects on surveillance technology such as Surveillance Watch and Feminist Smart Cities have offered an insightful approach to our project. Surveillance Watch aims to reveal which countries surveillance entities, or companies, are collecting data from, and who funds this data extraction. Although they provide detailed information about companies and funders, the project provides a big picture, global perspective.

      Our project intervenes by providing a closer look into not only the surveillance of LA County, but also what cities – both across the nation and internationally – the vendors are headquartered.
