How to treat the installation of face recognition cameras in many well-known shops?

Installing a face recognition camera in a store has advantages and disadvantages. In this case, we can clearly see who did what and reduce many unnecessary disputes. The disadvantage is that shoppers have less privacy, which affects their mood. Personally, I don't want to recognize my face when shopping. You can shop freely. Shopping under the camera seems to be monitored. I understand that most supermarkets now have monitors, which is actually very advantageous because there are many people in the supermarket. After many people, forgetfulness or thieves may appear. Through monitoring, you can watch the video back and find what you are looking for. Of course, face recognition is clearer than this monitoring, and it is definitely easier to find things. However, too precise instruments also bring people a lot of trouble. Can this face recognition still be preserved? Nowadays, many softwares are equipped with face recognition and information of some illegal software sellers to make profits. I think this kind of behavior is wrong. Maybe this is the advantages and disadvantages brought by science. I still hope that the relevant government departments can make regulations and install face recognition cameras, but don't do things that are not good for the people, don't make people feel uncomfortable, and don't ruin people's shopping mood. In this case, I personally support it. This is also the impact of scientific and technological progress, both good and bad. We should try our best to improve it, hoping to bring more convenience and create value to people's lives. I think we should tell people the purpose of installation and the implementation arrangement under acceptable conditions. Now people's privacy is getting less and less private. Our location is exposed to any software. Actually, it depends on your opinion. Some people may think it's okay, but some people may feel that they are being monitored. The technology is really too developed. What worries me most is that some people use the information obtained through these channels to gain benefits. I hope that all departments can strictly prevent and control management.
