I think the use of surveillance cameras are very good as they help to track down the identities of criminals before they get away with the crime.
Disadvantages:
I think it is not a good way to put cameras everywhere as they invade other peoples privacy. Using so many cameras also contribute to global warming as more cameras are installed the greater the amount of electricity it has to use in order to make the cameras work.
In conclusion:
I think we should in stall surveillance cameras at certain important places. Thus we can solve most of the criminal activities while not harming the environment so rapidly
