An image shared on social media raised doubts about the presence of small cameras installed on shelves in some Continente stores. The photograph, published on Reddit, sparked discussion among users and led several consumers to ask whether the devices were connected to customer surveillance or the management of the products on display.
According to the technology and current affairs website, which cites information confirmed by Polígrafo with the company, the cameras are part of a pilot project by MC, owner of Continente. The company guarantees that the objective is to improve the operational efficiency of stores, focusing on products and price tags.
What are these cameras?
The image that circulated online shows a small camera installed directly in a supermarket linear. The location of the device was strange, as it was not a traditional monitoring camera placed on the ceiling or at the store entrance. Being close to products, some users speculated that it could be used to read QR codes, update digital prices or track consumer movements.
The official explanation goes in another direction. According to information cited by Pplware, it is a solution integrated into a pilot project that is being tested in some stores.
Continente says its objective is to manage stocks
Asked about the case, an official source from Continente explained to Polígrafo that MC implemented “a pilot project that uses fixed cameras installed on linear lines, with the aim of reinforcing efficiency in stock management”.
The same source added that these devices allow “identifying product outages and inaccuracies on price tags”. In practice, the cameras are used to see if there are products missing from the shelf or if there is any discrepancy between the displayed item and the stated price. The technology thus functions as a tool to support the internal management of stores.
Company removes customer surveillance
Privacy was one of the main doubts raised after the photograph was released. According to the explanation given by the company, the solution “focuses exclusively on product monitoring”, and is not programmed to capture or identify customers. MC also guarantees that the project fully complies with personal data protection standards.
This point is relevant because the presence of cameras in places close to consumers can raise questions about collecting images, identifying people or analyzing behavior. The company’s version is that the purpose is logistical and operational.
Why are they on the shelves?
The placement of cameras in the linears allows direct observation of the condition of the shelves. In a supermarket, a product outage can mean a lost sale. An incorrect label can generate complaints, errors in the final price or loss of trust among consumers.
By identifying these problems more quickly, the store can replace items, correct labels or adjust internal processes. It’s a way of automating a task that, for years, depended mainly on employees’ manual observation.
Technology in retail is nothing new
This is not Continente’s first bet on technology based on cameras inside stores. Pplware recalls that, in 2021, the Continente Labs store used 230 cameras installed on the ceiling to monitor movements within the space and detect interactions with shelves, without resorting to facial recognition.
The difference now is in the location and the declared objective. The cameras appear on the shelves themselves and, according to the company, are intended for managing products, stocks and labels.
Smart stores have already arrived in Portugal
The project is part of a broader transformation of food retail. In January 2025, Continente opened in Leiria what it described as the largest smart store in the world. These store models seek to make the purchasing process more automated, reduce operational errors and improve product availability.
The technology used in these spaces may include cameras, sensors, digital payment systems, electronic tags and shelf analysis mechanisms. The objective is to make the operation faster and less dependent on constant manual checks.
What changes for those who shop?
For the customer, the presence of these cameras may go unnoticed. The company claims that the system is not designed to identify people, but to verify products. If it works as expected, consumers may notice better stocked shelves, fewer pricing errors and faster replenishment of items.
Still, the discussion shows that consumers are more attentive to the presence of technology in commercial spaces. Even when the purpose is logistical, the use of cameras in a shopping environment tends to raise doubts about privacy and transparency.
