The cameras are wide angle and are placed to achieve maximum coverage. There is one of each floor that can monitor the front doors of every flat. One in the foyer, one on the ground floor, two outside the building, two in the basement, and three in the garage. There are blind spots for certain but we always get a result. The most recent incident was an alleged assault by a person wearing an Elvis mask last September. The police were able to see that victim was not telling the truth.
