A city’s surveillance network could become a costly mistake if it buys cameras and analytics without clear purposes, full lifecycle budgeting, enforceable data limits, and public oversight. But the available audits and local cost estimates do not show that any city has lost a billion dollars—or establish a billion-dollar total across cities. The figure is a warning about potential exposure, not a verified bill.
What “smart surveillance” can include
“Smart surveillance” is an umbrella term, not one technology. A municipal system might combine ordinary cameras, automated license plate readers (ALPR), facial recognition, or sensor-equipped streetlights. The data collected, ability to identify or track people, and risks differ by system and by how a city connects it to other databases.
The central question is whether a proposed system’s documented public benefits justify its complete cost and its effects on privacy, security, and civil liberties. A purchase price alone cannot answer that: a city also needs to account for installation, recurring service, power, repairs, replacement, staffing, cybersecurity, compliance, and oversight.

What a local proposal can cost—and what the estimate leaves out
A San Diego Police Department surveillance impact report gives a concrete, proposal-specific example for a smart streetlight and ALPR deployment. The figures below come from that department report, which is undated in the reviewed PDF; they are proposal estimates, not confirmation of a current contract or a complete lifetime cost.

| Cost item | What the report estimated | Qualification |
|---|---|---|
| Units | Approximately $4,000 per unit, with 500 units proposed | San Diego Police Department proposal estimate; report undated in the reviewed PDF. |
| Installation | One-time charge of $1,500,000 | San Diego Police Department proposal estimate; report undated in the reviewed PDF. |
| Initial total | Approximately $3,500,000 for the initial 500 units, including units and installation | San Diego Police Department proposal estimate; report undated in the reviewed PDF. |
| Recurring payment | $2,000,000 per year for every 500 units deployed | San Diego Police Department proposal estimate; report undated in the reviewed PDF. |
| Power and possible streetlight-related savings or repairs | Not stated as settled amounts | The report said these were still being evaluated. |
That estimate shows why a headline purchase figure is not a full budget. It does not settle power or repair costs, and it should not be multiplied or presented as a universal price for other cities. The report also described annual review by the Privacy Advisory Board and City Council, internal audits, and Council approval for adding units. Those are the department’s stated proposal terms, not independent confirmation that each safeguard was implemented or effective.
What the audits show about oversight failures
Los Angeles: gaps in the citywide process
The Los Angeles City Controller’s audit, “Protecting Privacy Makes a Smarter L.A.”, found that the city had not defined surveillance technology, maintained a comprehensive inventory of technologies in use, or operated a formal, standardized surveillance impact assessment process at the time of the audit. The Controller recommended defining the term, identifying city systems, standardizing impact assessments and public reporting, establishing public advisory review, and revisiting assessments when systems or data practices materially change. These findings concern Los Angeles’ processes at the time of that report; they do not describe every city or establish current conditions in Los Angeles.

California: a policy on paper is not proof of a safeguard
The California State Auditor’s Report 2019-118, published February 13, 2020, examined ALPR programs at four local law-enforcement agencies. It found that the agencies’ policies did not all include required elements and identified risks involving sharing, retention decisions not tied to usefulness, access practices, audits of system use, contracts, and data security. Those findings are limited to the four agencies and the audit period.
Recommended Free Tools
The same report surveyed 391 police and sheriff departments statewide. Among responding California law-enforcement agencies that used ALPR, 96 percent said they had policies, and at least 70 percent said their policies were posted on their websites. The auditor cautioned that policy presence did not establish completeness or quality. A published policy therefore needs to be checked against contracts, system logs, training, and actual audit practice.

Can police track your car, and who can see the data?
ALPR systems capture license plates and can associate a plate with a time and place. Whether a particular city’s system can be used to look up, retain, or share that information depends on its technology, policy, contracts, and applicable rules. The California audit identified concerns around access, sharing, retention, and monitoring; it does not establish that every department uses data in the same way.
To find the answer for your city, look for its ALPR or surveillance impact report and ask:

- Which staff roles and outside agencies may access the data, and are those permissions recorded in access logs?
- What purposes and searches are authorized, and what training is required?
- How long is information retained, when is it deleted, and what exceptions apply?
- Can a vendor or another agency access or store the data, and what limits govern onward sharing?
- Who audits searches and sharing, how often, and are findings reported publicly?
There is no single retention period or access rule established by these sources for all cities. The local policy and the practices that implement it determine the answer.
How to judge whether a city proposal is worth the cost
Residents, journalists, and council members can use the same due-diligence questions before a system is approved or expanded. The Los Angeles audit and California ALPR audit support scrutiny of inventories, assessments, access, sharing, retention, security, and oversight; San Diego’s report illustrates the value—and limits—of publishing local cost estimates.

- Define the problem and alternatives. What specific public problem is the city trying to address? What evidence supports this tool, and could a less intrusive approach meet the need?
- Request the full lifecycle budget. Ask for hardware, installation, subscriptions, data plans, power, repairs, replacement, staffing, security, and oversight costs across the proposed contract term. Separate one-time charges from recurring payments.
- Map the data. What is collected? Can it identify people or reveal movement? Is it linked to other databases, and who owns or hosts it?
- Set enforceable data rules. Require clear authorized uses, named user roles, training, retention and deletion rules, and limits on sale or sharing. Make vendor and interagency terms explicit.
- Require operational oversight. Publish an inventory and impact assessment; keep access logs; schedule recurring independent audits; report results and complaints; and reassess the system when its technology, purpose, or data practices change.
- Measure results and distribution. Define outcomes before deployment, disclose error or failure rates where relevant, and examine where systems are used and who experiences their effects.
These are evaluation questions, not proof that every listed failure has happened in every deployment. A sound decision should make the purpose, evidence, full cost, data safeguards, and accountability mechanisms visible before approval—not rely on a vendor description or a policy document alone.
What residents said about San Diego’s proposal
The San Diego report summarized a city survey conducted January 31–February 19, 2023. It involved 914 adult respondents recruited online, with results weighted to represent the city. In that department-reported survey, 42 percent said they would feel more safe if license plate readers were introduced, while 13 percent said they would feel less safe. Those responses reflect reported perceptions, not measured crime reduction or national opinion.
The report also compiled public comments raising issues such as immigration-enforcement use, camera deployment in District 8, public access to audit information, and the overall cost and additional services. These are examples from the report’s comments, not representative polling questions. They point to the kinds of practical questions a city should answer publicly before deployment.
Is a city’s smart surveillance a billion-dollar blunder?
The cited material documents local governance gaps, ALPR safeguards that fell short in four audited programs, and a San Diego proposal with substantial stated costs and unsettled expenses. It does not verify a billion-dollar loss or support a reliable national total. Establishing such a figure would require a defensible model with comparable city-by-city costs, contract terms, time periods, and evidence of losses; the sources here do not provide that.
The warning is best understood as a question of avoidable exposure: can the city show why it needs the system, what it will cost over its life, what data it will collect and share, and how the public can verify that safeguards work? If it cannot, the burden is not merely a line item in a budget—it is an accountability failure as well.
