a communication interface for receiving at least one image signal from at least one camera and transmitting a first control signal to at least one storage device;
a user interface for receiving a user input;
generating a multi-screen based on the at least one image signal, recognizing an event from the at least one image signal, generating first time information for the event, and generating the at least one image in response to the user input a processor for generating a new multi-screen based on at least one image corresponding to the first time information among signals and generating the first control signal including the first time information in response to the user input; and
Including; a display module for displaying the multi-screen or the new multi-screen;
The communication interface receives a second control signal including second time information from the at least one storage device,
and the processor generates a new multi-screen based on at least one image corresponding to the second time information among the at least one image signal in response to the second control signal. The method according to claim 1,
The communication interface receives at least one sound signal from the at least one camera,
The processor recognizes the event from the at least one sound signal, a monitoring system. The method according to claim 1,
The first time information includes at least one of start time information and end time information of the event, a monitoring system. delete Receiving at least one video signal from at least one camera through a communication interface;
generating, by a processor, a multi-screen based on the at least one image signal;
displaying the multi-screen by a display module;
recognizing, by the processor, an event from the at least one image signal;
generating, by the processor, time information for the event;
receiving, through a user interface, a user input for selecting the event;
generating, by the processor, a new multi-screen based on at least one image corresponding to the time information among the at least one image signal in response to the user input, and generating a control signal including the time information step;
displaying, by the display module, the new multi-screen; and
transmitting the control signal to at least one storage device by the communication interface;
receiving, by the communication interface, a second control signal including second time information from the at least one storage device; and
generating, by the processor, a new multi-screen based on at least one image corresponding to the second time information among the at least one image signal in response to the second control signal; how it works. a communication interface for receiving at least one image signal from at least one camera; and
generating a multi-screen based on the at least one video signal, recognizing an event from the at least one video signal, generating first time information for the event, and generating the first time from the at least one video signal A processor for generating a new multi-screen based on at least one image corresponding to information and generating a first control signal including the first time information;
The communication interface transmits the first control signal to at least one other storage device that does not generate the first control signal,
The at least one other storage device generates a new multi-screen based on at least one image corresponding to the first time information in response to the first control signal.
