Sounds a lot like UK. As someone else pointed out - Europe is way to diverse to call as a single entity with this scope. Large cities in UK are quite heavily monitored, but if you look at Europe in general, then the surveillance is centered around government buildings, embassies etc.

In Denmark you can have quite a lot of cameras in shops and outside petrol stations, which is the business owners way to up their security. But those are NOT allowed to film anything facing away from the premises, meaning you can't just film people on the street from these cameras.
