1. A method for person detection by a computer device, comprising:
receiving a plurality of video frames from a camera located in an environment, wherein the video frames include a depiction of a person in the environment;
identifying attributes of the person from the video frames;
comparing the attributes with attribute entries in a database of suspicious persons, wherein the database of suspicious persons includes attributes of a plurality of persons associated with an alert in the environment;
retrieving a profile indicative of an alert history of the suspicious person in response to determining a match between the attributes of the person and an entry in the database corresponding to a suspicious person;
determining a scale of crimes committed by the suspicious person based on an amount of time between incidents of a certain type, wherein the certain type is one of theft at a particular store or theft of a particular product type;
determining, based on the profile, a rank of the suspicious person in the database of suspicious persons based on a frequency and the scale of crimes committed by the suspicious person compared to other suspicious persons; and
transmitting, to a second computer device, the retrieved profile and a notification that indicates that the suspicious person is in the environment when the rank exceeds a threshold rank.
