Method and apparatus for physical security over a power line connection

A BPL slave unit comprising:

• a processor;
• a local memory device in communication with the processor;
• a removable storage device in communication with the processor;
• and
• a powerline transceiver in communication with the processor,
• wherein the processor is configured to transmit and receive data over a power line via the powerline transceiver, wherein the processor is in communication with a plurality of systems, and wherein the processor is further configured to:
• receive a plurality of data from the plurality of systems;
• determine whether or not the powerline transceiver is connected to a BPL master control unit;
• transmit, via the powerline transceiver, the plurality of data to the BPL master control unit if the powerline transceiver is connected to the BPL master control unit;
• and
• store, in the removable storage device, the plurality of data if the powerline transceiver is not connected to the BPL master control unit.

A method for communicating via a BPL connection, the method implemented by a master control unit including a processor in communication with a memory, the method comprising:

• detecting, via the BPL connection, a connection to a slave unit;
• receiving, via the BPL connection, a plurality of data from the slave unit;
• determining a destination for the plurality of data;
• comparing two or more transmission methods for transmitting the plurality of data to the destination;
• and
• transmitting the plurality of data to the destination via one of the two or more transmission methods based on the comparison.
