Concerns have been rising over the use of Flock Safety cameras by police departments. The founder of Flock Safety believes the technology could have helped in a missing-person case. The case involves Nancy Guthrie, who disappeared in February.

She is the mother of a TV host. Details of her disappearance include footage from a doorbell camera showing a masked man tampering with it. Further information on the case and Flock Safety's claims are available from the source, including the company's assertion that its technology has helped solve a significant number of missing-person cases.
