The société mère de Sports Direct affirme que la technology de reconnaissance faciale en direct (LFR) a réduit la criminalité dans ses magasins.
The cameras compare faces to a watch list using a system called Facewatch.
Lundi, 50 députés et pairs ont soutenu une lettre s'opposant à l'utilization de TFR par le groupe Frasers du propriétaire de l'entreprise Mike Ashley et d'autres chaînes telles que Flannels.
The company says the technology will notify shoppers when it's installed in-store.
The Frasers Group told BBC News it takes its commitments to TRF very seriously and stresses its effectiveness.
“After installing this technology, we have seen a significant reduction in crime in our stores.
A letter criticizing its use was organized by campaign groups Big Brother Watch, Liberty and Privacy International.
He says research on facial recognition technology suggests;
87% of "matches" in court cases against the Metropolitan Police incorrectly identified innocent people
Women and members of certain ethnic minorities are more likely to be misidentified than white men
The technology met fin au principe démocratique de suspicion qui précédait la surveillance et "traite quiconque passe devant la camera comme un criminel potentiel", add la lettre.
Signatories to the letter come from all walks of life and include:
former Conservative Minister David Davis MP
former Labor Shadow Chancellor John McDonnell MP
Tim Farron MP, former leader of the Liberal Democrats
Green MP Caroline Lucas
Activists claimed in March that the technology was being used in at least 27 Frasers Group stores.
Facewatch claims its system has proven effective in deterring crime.
"Malheureusement, dans Certains magasins, ils sont confronted à des unacceptables et à des abus de la part de criminels contre leur personal. C'est dans ces magasins que Facewatch est mis en place", a statement from the Fondateur de l'entreprise, Simon Gordon at BBC News.
Facewatch's shared national facial recognition database alerted employees when someone entered a subscriber's store, he said.
Requests from business leaders to add someone to the database had to be supported by full testimony and explanations, which were reviewed by a panel of former police officers, before being granted, Gordon said.
"Due process will be followed to ensure that only those with reasonable suspicion of crime are admitted," he said.
He told BBC News that store staff and "accredited super-detectors," analysts with facial recognition skills, review each alert.
Gordon disputes the accuracy of the letter's claims about the Met Police LFR, saying Facewatch is over 99% accurate.
Their numbers have not been independently verified.
Facewatch says its TFR system follows the CCTV Code of Conduct, which applies to police and local authorities but is optional for private companies.
The code has been criticized for providing only "basic" guidelines, with some experts suggesting new legislation is needed.
But Gordon said the Information Commissioner confirmed that Facewatch use was legal.
However, the ICO has previously raised serious concerns about TFR technology, stating that apps must meet a "high bar".
"We should be able to take our children to an amusement park, visit a mall or go sightseeing without having to collect and analyze our biometric data," the former commissioner wrote on his blog. Information, Elizabeth Denham. .
