Abstract
An emergency voice communication technique through the Internet using a VoIP (Voice over Internet Protocol) Internet phone between a central control center and a digital video recorder or between remotely located digital video recorders. The operator of the digital video recorder immediately calls the Internet phone of a predetermined remote workstation only by lifting the handset of the Internet phone connected to the digital video recorder when an alarm event is generated in the digital video recorder. If an alarm event occurs in the remote workstation, the operator of the remote workstation immediately calls the Internet phone of the digital video recorder by lifting the handset of the Internet phone connected to the remote workstation. VoIP communication between remotely located digital video recorders can be carried out through a network or the Internet using Internet phones connected to the digital video recorders.
