Abstract: Examples described herein relate to systems, apparatuses, and methods for a microphone device that includes a microphone configured to output sound data signals, a first circuit board configured to perform audio analytics on the sound data signals, a second circuit board configured to extract power for powering the first circuit board, a housing configured to contain the microphone, the first circuit board, and the second circuit board, and an Ethernet interface configured to connect the second circuit board to a security system through an Ethernet connection.

Abstract: An interface device is configured for interfacing one or more external devices to Ethernet Power Source Equipment PSE. The interface device includes a jack for connection to the PSE, and first and second output jacks. The first output jack provides an Ethernet power and data connection for an external device. The second output jack provides a DC power connection for an external device. A power extractor circuit provides a signature to the PSE, and provides a predefined output signal in response to receiving a power signal from the PSE. At least one delay element electrically connects the network connection jack and the first output jack, after a predefined delay from a time at which the power extractor circuit provides the output signal.
