A video system can use AI analytics to recognize a person, vehicle, object, or event and send an alert for an operator to review. That is already a real physical-security application—but it does not mean every camera is AI-enabled, that every organization uses these systems, or that an alert is proof of wrongdoing.
How is AI used in physical security?
The clearest established use is video analytics: software analyzes camera footage to classify what appears in a scene or identify a specified event, then generates an alarm for people responsible for security. The Security Industry Association (SIA) describes these capabilities in its 2025 video-surveillance privacy code and its overview of AI in physical security.

In practice, the useful distinction is between an AI-generated signal and a security decision. Analytics may help direct attention to a camera or event; an operator still needs to assess what happened and decide whether a response is appropriate. A detection is not, by itself, proof of identity, intent, or a threat.

Beyond alerts
SIA’s April 8, 2025, Technology Insights issue describes visual AI applications including intrusion detection, occupancy management, and safety-compliance monitoring. These are examples of industry-described use cases, not independent evidence that a particular product performs them reliably in every setting.

What can AI security cameras detect?
Depending on the system and how it is configured, video analytics can classify humans, vehicles, and other objects, or flag events defined by the product. The phrase “AI camera” alone does not tell you which of these functions are included. Analytics may be provided by a camera, a separate server, cloud software, or a combination of components.
Ask the vendor to specify the task precisely. “Detects a person in a restricted area” is different from identifying a named individual, predicting behavior, or automatically triggering a consequential action. Do not assume that a system can infer intent or make reliable identity judgments just because it can classify objects in video.

Where does the analysis run?
Physical-security AI can process video on a device, on a dedicated server, in the cloud, or through a hybrid arrangement, according to SIA’s physical-security AI overview. There is no universal winner: the right fit depends on the installation, the data involved, and the organization’s operational and privacy requirements.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- On-device: Ask which analysis actually happens on the camera and whether footage or metadata is also sent elsewhere.
- Dedicated server: Establish who operates and secures the server, what systems it connects to, and who maintains its software.
- Cloud: Identify what information leaves the site, where it is processed and retained, and which parties can access it.
- Hybrid: Map which tasks happen locally and which rely on a server or cloud service; “hybrid” alone does not explain the data flow.
For any arrangement, request a plain-language data-flow description covering video, derived data, alerts, storage, access, and deletion. Also confirm that the cameras, recorders, analytics software, and any access-control integrations you plan to use are compatible. Compatibility must be verified for the specific installation; a network camera is not automatically compatible with a particular analytics platform.

Is AI surveillance accurate?
There is no defensible universal accuracy figure in the sources cited here. A broad claim that an AI security system is “accurate” is not enough to assess a particular deployment. Performance evidence needs to match the intended task and the conditions where the system will operate, including camera position, lighting, locations, and the events that matter to the organization.
Ask the vendor what it counts as a correct detection, how it tests missed events and false alerts, and whether its evidence reflects your intended environment. Find out how the system behaves when the view is obstructed or conditions change, and whether staff can review the footage and understand why an alert was generated. An alert can be useful without being conclusive; the workflow should account for that distinction.

What are the privacy and security risks?
Video analytics can turn recorded footage into searchable or inferential information about people. NIST’s “Cybersecurity, Privacy, and AI” page, updated July 15, 2026, identifies risks including re-identification, new insights about people, and expanded behavioral tracking and surveillance. The privacy question is therefore not only whether video is stored, but also what the system can infer, who can use those inferences, and for what purpose.

Cybersecurity and governance matter too. In a 2025 report on federal critical-infrastructure sector assessments, the U.S. Government Accountability Office (GAO) found that the assessments it reviewed identified AI uses such as physical surveillance but did not fully address the activities needed to establish a foundation for assessing and mitigating AI risks. That finding concerns the federal assessments GAO examined; it is not proof that every AI security deployment is unsafe.

For critical infrastructure, DHS’s November 14, 2024, framework announcement encourages strong privacy practices, evaluations for bias, failure modes, and vulnerabilities, and independent assessments for models presenting heightened risks to critical infrastructure and consumers. These are also useful governance questions for buyers beyond that specific federal context.
Controls to establish before deployment
- Define the security purpose and the permitted uses of the system; document who may view footage, alerts, and derived information.
- Set rules for retention, access, sharing, deletion, and review of system activity.
- Evaluate potential bias, failure modes, and vulnerabilities, and establish a process for investigating problems.
- Require cybersecurity controls and a plan for updates, support, and incident handling.
- Specify when a human must review an alert before it leads to action, and how staff can challenge or correct an incorrect result.
SIA’s 2025 video-surveillance privacy code is specifically intended to guide privacy practices for video surveillance. Use applicable policies, laws, and organizational requirements to determine what safeguards are necessary for the location and use case.
What should you ask an AI security vendor?
SIA’s October 30, 2025, enterprise vendor-evaluation report includes a questionnaire. Adapt its focus into a procurement discussion that asks for concrete answers rather than relying on broad claims about “AI-powered” security.

Ask what AI method or function is used, what it detects, and what it does not do. Separate classification and alerting from identification, prediction, or automated action.
- What evidence supports the claim? Request test methods and results for the intended task, including how the vendor evaluates missed events, false alerts, bias, and failure modes. Ask whether the test conditions resemble your cameras, locations, and operating environment.
- What data is involved? Identify the video and other data sources used, what information is produced, where processing occurs, how long data is retained, and who can access it.
- How is the system secured and governed? Ask for cybersecurity controls, relevant compliance evidence, vulnerability-handling practices, update and support arrangements, and procedures for a security incident.
- What human review is required? Establish who receives an alert, what evidence they can inspect, and what review is required before anyone acts on it.
- Will it work with the equipment already installed? Confirm support for the exact cameras, recorders, analytics components, and integrations in your proposed setup, then document how compatibility and ongoing support will be maintained.
A credible answer should describe the specific system and its limits, not treat the word “AI” as a performance guarantee. Keep the vendor’s claims, test evidence, data practices, and human-response procedures together in the evaluation so that a promising demonstration is not mistaken for a complete deployment plan.
