20 Active Shooter and Active Killer Prevention Strategies

17. Security cameras with facial recognition software

Security camera technology has been improving dramatically in recent years. Newer systems enable the photographs of persons of interest to be uploaded into the system, which can often detect the person in a crowd through facial recognition software. Though these systems have limitations, they can provide an additional layer of detection if photographs of a person who may pose a threat are available. For example, if a terminated employee who has been banned from the property attempts to enter the campus to attack former supervisors and/or colleagues, this type of system might be able to detect his or her presence on or near the campus.
