Facial recognition analyzes facial images to create or compare biometric templates that can identify, verify or authenticate a person. The distinction is what the software does with the video and what it outputs, not what the camera looks like.
What each technology does
Retail video analytics
Video analytics software extracts information about events or patterns in camera footage. Retail examples include counting visitors and mapping movement with heat maps. Security systems can also analyze video for suspicious behavior and alert staff. The FTC describes footfall counting and heat maps as uses that typically do not employ facial recognition or identify consumers across locations; NIST describes video analysis for retail security alerts.

Facial recognition
Facial recognition is identity-oriented. The ICO defines it this way: “Facial recognition technology identifies or otherwise recognises a person from a digital facial image.” The software measures facial features and produces a biometric template, which may be compared with other templates to identify someone, verify or authenticate a claimed identity, or categorize people. In a live public-space deployment, a system may compare faces with a watchlist; a human commonly reviews suggested matches. ICO guidance

Face detection and counting are not automatically recognition
A system that detects that a face is present, or counts people without identifying them, is not necessarily performing facial recognition. A 2020 FTC PrivacyCon paper treats anonymous people counting, anonymous face detection and facial recognition as distinct functions. Conversely, “video analytics” does not guarantee anonymity: configuration, additional sensors, data linkage and the specific analytic function matter. FTC PrivacyCon paper

The same camera can feed different software, and a broader system can combine functions. To understand a store’s deployment, ask what inputs it processes, what outputs it produces, whether those outputs are linked to a person, and what the operator uses them for.
How to tell what a store system actually does
- Purpose: Is it measuring aggregate store flow, flagging possible loss-prevention events, authenticating a person, or matching faces against a watchlist?
- Identity: Does it produce or compare a template tied to a named or otherwise linkable person, or does it only count or analyze activity?
- Data and retention: What raw footage, biometric templates, derived analytics and linked records are stored, for how long, and who can access them? The PrivacyCon paper distinguishes retention of raw footage from retention of analytics results.
- Accuracy and consequences: Request false-positive and false-negative measurements for the actual deployment and learn what happens when the system is wrong. A single accuracy figure without test conditions is not enough.
- Human review: Who checks a suggested match, and how meaningful is that review before anyone is stopped, denied entry or treated as suspicious?
- Privacy and oversight: What notice, choice, justification, safeguards and jurisdiction-specific legal requirements apply?
- Vendor and security controls: Who else can access the data, how is the system monitored, and how does the retailer address foreseeable risks?
If the aim is only to understand footfall or movement, ask whether aggregate analytics can meet it without identifying customers. In UK guidance, the ICO says facial recognition in settings such as shopping centres needs a strong justification that it is lawful and necessary and could not be achieved through less intrusive methods.

Why accuracy depends on the video and the task
Facial recognition performance in video depends on image quality and operating conditions. In a 2017 evaluation, NIST tested 36 prototype algorithms from 16 commercial suppliers using 109 hours of video and galleries containing up to 48,000 people. The report described identification rates ranging from around 60% to more than 99%, depending on the algorithm and video or image quality. These are results from that evaluation and its scenarios—not a current performance guarantee or a general accuracy range for retail products. Small faces, uneven lighting, non-frontal views and occlusion made identification harder. NIST’s 2017 report summary
Those figures concern identification in particular test conditions. They do not by themselves tell a retailer how often its system will wrongly flag a shopper or miss a person in its actual environment. Ask for deployment-specific error rates and the test conditions behind them, especially where a false match could lead to someone being challenged or refused service. NIST’s lead author noted: “Our research revealed that the video images’ quality and other properties can highly influence the accuracy of facial identification.”

Privacy and legal rules depend on where and how it is used
United Kingdom
For facial biometric processing used to uniquely identify people, the ICO says organisations need both a UK GDPR Article 6 lawful basis and an Article 9 condition, alongside applicable requirements under the Data Protection Act 2018. Its guidance advises a data protection impact assessment, a documented case for necessity and proportionality, an explanation of why less intrusive options are insufficient, monitoring for false matches and demographic differences, and meaningful human input where decisions affect people. These are UK-specific requirements and guidance, not a summary of the law in every country. ICO guidance
United States
The FTC warns that biometric technologies can raise privacy, data-security, bias and discrimination concerns, including when collection is unexpected, vendor practices are inadequate or systems are not properly monitored. Its Rite Aid case summary reports that a settlement prohibits the company from using facial recognition for security or surveillance for five years. That is a specific US enforcement case, not proof that every retailer uses facial recognition or that every use is unlawful. The FTC’s 2023 warning describes biometric surveillance as posing “new threats to privacy and civil rights.” FTC warning · FTC Rite Aid case summary
