A system for alarm processing, the system comprising: a plurality of security devices, each of the plurality of security devices being configured to generate one or more alarms in response to one or more alarm events, the plurality of security devices being divided into at least one group, one group of the at least one group including a first security device and one or more second security devices, wherein the first security device is configured to: receive, from the one or more second security devices, one or more first alarms generated by the one or more second security devices; determine that an alarm condition is satisfied based at least on one of the one or more first alarms and one or more second alarms generated by the first security device; and send, based on the determination, at least one of the one or more first alarms and the one or more second alarms to a user terminal, characterized in that, each of the one or more first alarms and the one or more second alarms corresponds to an evaluation value that indicates an emergency degree of the corresponding alarm event, and to determine that an alarm condition is satisfied based at least on one or more first alarms and one or more second alarms generated by the first security device, the first security device is configured to: determine that a summation of the evaluation values of the one or more first alarms and the one or more second alarms is greater than a threshold value. a plurality of security devices, each of the plurality of security devices being configured to generate one or more alarms in response to one or more alarm events, the plurality of security devices being divided into at least one group, one group of the at least one group including a first security device and one or more second security devices, wherein the first security device is configured to: receive, from the one or more second security devices, one or more first alarms generated by the one or more second security devices; determine that an alarm condition is satisfied based at least on one of the one or more first alarms and one or more second alarms generated by the first security device; and send, based on the determination, at least one of the one or more first alarms and the one or more second alarms to a user terminal, characterized in that, each of the one or more first alarms and the one or more second alarms corresponds to an evaluation value that indicates an emergency degree of the corresponding alarm event, and to determine that an alarm condition is satisfied based at least on one or more first alarms and one or more second alarms generated by the first security device, the first security device is configured to: determine that a summation of the evaluation values of the one or more first alarms and the one or more second alarms is greater than a threshold value. receive, from the one or more second security devices, one or more first alarms generated by the one or more second security devices; determine that an alarm condition is satisfied based at least on one of the one or more first alarms and one or more second alarms generated by the first security device; and send, based on the determination, at least one of the one or more first alarms and the one or more second alarms to a user terminal, characterized in that, each of the one or more first alarms and the one or more second alarms corresponds to an evaluation value that indicates an emergency degree of the corresponding alarm event, and to determine that an alarm condition is satisfied based at least on one or more first alarms and one or more second alarms generated by the first security device, the first security device is configured to: determine that a summation of the evaluation values of the one or more first alarms and the one or more second alarms is greater than a threshold value.
