Abstract: System and method for alarm processing are provided. The system may include a plurality of security devices. The plurality of security devices may be divided into at least one group. One group of the at least one group may include a first security device and one or more second security devices. The first security device may receive, from the one or more second security devices, one or more first alarms generated by the one or more second security devices. The first security device may 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. The first security device may 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.

Abstract: A system and method for controlling network congestion are provided. The method may include one or more of the following operations. One or more alert signals corresponding to one or more alert events of one or more urgency levels may be obtained at a first time of interest. A network condition of the network at the first time of interest may be obtained. A congestion assessment (CGA) at the first time of interest may be performed based on the network condition. A first communication protocol for sending the one or more alert signals may be determined based on the CGA. A first batch of alert signals of the one or more alert signals may be caused, based on the first communication protocol and the urgency levels of the one or more alert signals, to be sent via the network.
