A device and method to identify visitors and notify the resident of the identified information of the visitor before the resident opens the door for the visitor. The device reads/scans the fingerprint of the visitor as they activate the Smart Doorbell Switch by pressing the Smart Doorbell Switch with their finger, preferably their thumb. Identifying information associated with the scanned fingerprint is retrieved and announced for the Resident. The visitor's fingerprint is also checked with an Alert Database to check if there is an alert tied to the fingerprint. If so, the appropriate authorities will be contacted and the resident will be alerted. |
