Abstract
An alarm system monitors a home, business, or other property for fire, burglary, break-in, or other event that may warrant raising an alarm. The alarm system is configured to detect tampering, whereby someone intentionally impedes the ability of the system to raise an alarm or otherwise interferes the system's operation. An alarm panel of the alarm system communicates with a server. At certain times, the alarm system transmits a series of packets to the server using a unidirectional protocol. Upon receipt of one of the packets, the server alternates between monitoring for an incoming packet and ignoring any incoming packets. Detection of an incoming packet during a monitoring time period causes the server to transition to ignoring packets for a sleep period of time. Completion of the sleep period of time causes the server to return to monitoring for the monitoring period of time.
