Abstract: An active data push system comprising a plurality of human-detection devices and a management system is presented. The human-detection devices respectively send a trigger signal when detecting a human entrance into one of a plurality of zones. The management system recognizes the zone detected with the human entrance when receiving the trigger signal, and retrieves a basic data of each electronic device installed in the recognized zone, and transmits the retrieved basic data to a mobile device held by the human.

Abstract: A network video monitoring system includes a core-control module, a plurality of network video recording (NVR) hosts, and a plurality of cameras. The core-control module assigns the cameras to the NVR hosts respectively for controlling the camera by the NVR hosts according to status of each NVR host. In this application, the core-control module obtains the status of each NVR host periodicity for determining if the NVR hosts are over loading or failed, and re-assigns the cameras automatically for the overloaded or malfunctioned NVR hosts. The application rescues the NVR hosts from the over loading problem, and prevents the termination of the monitoring action of the cameras when one of the NVR host malfunctions.
