My neighborhood does not have much Technology to prevent crimes for example we have cameras but near stores and business not around or in our building. The very few that we do have is a shot spotter which is basically a machine that can detect gun shots and can alert officers right away. In some apartments doors you will see a ring camera but only very few own a ring camera. Another technology would be officers parking their patrol cars in the neighborhood it shows suspects that officers are around and many would not commit a crime if they see police officers.
