A private video surveillance service shares an image stream through an asset lock with government agencies in the event of emergency. Nominated agencies establish access credentials at the surveillance service data center. A camera is shared by a facility administrator's selection of permissions on each camera via privileged web-browser or mobile device. A government agency receives an electronic notification from the administrator to operate an agency dedicated application programming interface. A notification may be customized for each responding agency and each event by dynamically generating a transient link to a secure webserver which expires to limit exposure to ranges of date-time. Video servers remain controlled by the facility administrator.
