The invention relates to a monitoring alarm linkage processing method and system, and an integrated monitoring device. The method comprises the following steps: receiving, by the integrated monitoringdevice, alarm information from a subsystem device; based on the alarm information, triggering a video linkage scheme in a corresponding alarm linkage scheme; controlling a video monitoring device toexecute the video linkage scheme; receiving video linkage information from the video monitoring device; triggering a subsystem device operation scheme in the corresponding alarm linkage scheme according to the video linkage information; and controlling the subsystem device to execute the subsystem device operation scheme. According to the monitoring alarm linkage processing method and system provided by the invention, the alarm linkage scheme is uniformly configured, the integrated monitoring device is a linkage scheme planning party, the video monitoring device and the device subsystem are execution parties of the alarm linkage scheme, the logic is simpler, and the emergency response is more efficient.
