You will be fine. First of all, it usally takes so long time before shop eventually knows about the fraud that the CCTV will already be deleted. And its also very hard for police to identify you by just a picture. (I guess that depends on how big your city is, how many people lives there..) For example in a very small town with 20,000 people it would be easier than a town with 500,000 people as an example. Aslong your town is not too small, and you are not very known by the police then you will be fine.
I dont even think they will ask for CCTV unless maybe you carded a Rolex. Also I have carded without any disguise many times and never been identified/caught.
