This one remains really interesting, and difficult, for real estate developers and investors. The benefits for a property company of facial recognition technology on an estate are likely to be vastly outweighed by the potential risks of a data protection breach and adverse PR, even where that is just negative coverage from being found to be using that technology. It may be that a Commission decision to ban facial recognition (for however long the UK is aligned with that decision...) actually simply reflects what many property companies will do anyway.

The direction of travel with European data protection legislation is very much towards more control and protection for the individual, so it is hard to see how blanket facial recognition scanning sits with that and for most property companies the legitimate benefits of installing that technology are relatively nebulous. 

One of those times that the existence of a technology does not necessarily mean it should be used...
