Abstract

A security system comprises a system control panel for monitoring at least one device on a network. An infrared (IF) sensor located on the network has an IR transmitter and an IR receiver. The IR transmitter transmits control data packets and the IR receiver detects received data packets and IR data. A processor provides the control data packets to be transmitted by the IR transmitter. The processor determines that an external communication device is initiating communication with a target device over the network based on at least the received data packet received by the IR receiver. The processor establishes bi-directional communication over the network between the external communication device and the target device which is one of the processor, the system control panel and the at least one device.

3. The system of claim 2, wherein the IR sensor is located remote from at least one of the system control panel or the at least one device.

4. The system of claim 2, further comprising:

the target device sending target device data packets over the network to the processor; and

the IR transmitter transmitting the target device data packets wirelessly to the external communication device.

5. The system of claim 2, wherein the control data packets comprise at least one of a beacon or a broadcast signal based on a predetermined two-way wireless communication protocol.

6. The system of claim 2, wherein the received data packets further comprise external data packets transmitted from the external communication device, the processor identifying the target device based on the external data packets, the processor transferring at least a portion of the external data packets over the network to the target device.
