Networked security system

A security system, comprising:

• a security server;
• one or more master devices;
• and
• one or more slave devices,
• wherein each of the one or more master devices and the one or more slave devices is configured to:
• receive, from an access point, an access point identifier associated with the access point and a network address associated with the respective device, and
• transmit the access point identifier and the network address to the security server,
• wherein the security server is configured to:
• for each of the one or more slave devices, determine whether the access point identifier received from the slave device matches an access point identifier received from at least one of the one or more master devices, and
• for each slave device from which a matching access point identifier is received, transmit the network address of the slave device to each of the one or more master devices from which the matching access point identifier was received,
• wherein the one or more master devices from which the matching access point identifier was received are configured to receive the network address from the security server and use the network address to transmit one or more messages to the slave device on the local network.

A method of enabling communication between devices, the method comprising:

• associating a master device with an access point on a local network;
• receiving, at the master device, a first access point identifier associated with the access point and a first network address assigned by the access point to the master device;
• transmitting, from the master device to a security server, the first access point identifier and the first network address, wherein the security server is configured to receive a second access point identifier and a second network address from a slave device and, when the second access point identifier matches the first access point identifier, transmit the second network address to the master device;
• receiving, at the master device, the second network address from the security server;
• and
• transmitting one or more messages from the master device to the slave device on the local network using the second network address received from the security server.

One or more computer-readable storage media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to implement a method comprising:

• receiving one or more master registration messages from one or more master devices, each of the one or more master registration messages comprising a master access point identifier and a master network address associated with the master device from which the respective master registration message was received;
• receiving one or more slave registration messages from one or more slave devices, each of the one or more slave registration messages comprising a slave access point identifier and a slave network address associated with the slave device from which the respective slave registration message was received;
• for each of the one or more slave devices, determining whether the slave access point identifier in the slave registration message received from the respective slave device matches one of the master access point identifiers of the one or more master registration messages;
• and
• for each slave device from which a matching slave access point identifier is received, transmitting the slave network address of the slave device to each of the one or more master devices from which the matching master access point identifier was received;
• wherein the one or more master devices receiving the slave network address are configured to use the slave network address to transmit one or more messages to the slave device on the local network.
