Dahua Helps Carrefour Brazil Build a Smarter, Safer Retail Environment
Carrefour Brazil is one of the largest retail groups in Brazil and Latin America, operating more than 1,000 stores and serving a high volume of customers every day. Its Pamplona store in São Paulo, for example, located in one of the city’s busiest areas, greatly reflects the operational complexity faced by modern retailers: maintaining safety, reducing losses, improving efficiency, and delivering a better shopping experience at scale.
Challenges
Carrefour needed to address several key pain points. Manual processes and disconnected systems created risks of inaccurate alarms and inconsistent service. High customer traffic increased exposure to theft, fraud, and checkout losses, while traditional investigation methods made incident tracing slow and inefficient. At the same time, limited real-time visibility into customer flow, queues, inventory, and in-store behavior made it difficult to optimize staffing, replenishment, store layout, and checkout efficiency.
Solutions
To meet these needs, Dahua provided an integrated smart retail solution combining video surveillance, AI analytics, alarm linkage, customer flow analysis, and digital in-store technologies. The solution was built around Dahua’s DSS PRO platform, Retail Loss Prevention IVD/IVSS, Retail NVR, AcuPick intelligent search, people-counting cameras, Electronic Article Surveillance (EAS) integration, alarm host, access control, electronic shelf labels, and digital signage. These systems work together to connect security, operations, and customer engagement within a unified retail ecosystem.
For loss prevention, Dahua’s video analytics can detect suspicious behaviors such as item concealment and issue real-time alerts to security staff. Integration with EAS and intrusion alarms provides immediate contextual information for each alarm, helping teams respond faster and more accurately. High-value merchandise is further protected with anti-theft tags, while restricted storage areas are secured through access control. In the event of an incident, AcuPick and intelligent video analysis can be used to track the movement paths of customers or employees, significantly reducing investigation time.
The solution is also projected to checkout and self-checkout security. Cart analysis can help to identify unscanned items, while intelligent barriers at self-checkout stations prevent customers from exiting before completing payment. Looking ahead, the integration of video surveillance with transaction data can further support automated sales auditing, discrepancy detection, and faster resolution of operational variances.
Beyond security, Dahua’s smart retail technologies support data-driven store operations. People-counting cameras, customer flow analysis, queue monitoring, and heatmap analysis provide Carrefour with insights into occupancy, peak hours, movement patterns, high-traffic areas, and dwell time. This can help to optimize staff scheduling, product placement, promotional planning, and checkout lane management. Shelf replenishment monitoring enable detection of low stock or abnormal product removal and triggers real-time alerts, helping prevent lost sales and improving product availability.
Dahua also enhanced the in-store customer experience through electronic shelf labels and digital signage. Electronic shelf labels enable automatic price updates, reduce manual errors, and support promotional communication. Digital signage and point-of-sale displays provide product information, strengthen brand presence, and create a more interactive shopping environment.
Results
As a result, Carrefour Brazil now operates in a safer, more efficient, and more connected retail environment. The project improves operational visibility, strengthens loss prevention, accelerates incident analysis, supports better staffing and merchandising decisions, and enhances the customer journey from entrance to checkout. Through this collaboration, Dahua helped Carrefour transform traditional store management into an intelligent retail model powered by integrated security, analytics, and digital engagement.
