    摘要: A people counting system and method for the automatic reconfiguration of a failed people counting sensor device in a people counting system. The system includes a plurality of addressable people counting sensor devices defining a cluster having a master device in communication with at least one slave device, each of the master device and the slave devices having a corresponding Media Access Control (“MAC”) address. The master device is adapted to sequentially transmit power-on commands to each of the slave devices, assign a different node address to each of the slave devices, receive an association of the MAC address of the master device to the node address and MAC address of each of the slave devices to form a cluster configuration, store the cluster configuration as a cluster configuration table, and replicate the cluster configuration table to the slave devices. A dynamic host configuration protocol (DHCP) server assigns an IP public address to the master device.

    摘要: Systems and methods for operating a security system. The methods comprise: monitoring an area for a presence of an individual or vehicle using wireless signals of a first type that are received by a first radio of the security system; operating the first radio as a wireless sensor for generating sensor data; determining whether the individual or vehicle is exhibiting an unusual behavior using the sensor data and pre-programmed or machine learned patterns of unusual behavior; changing an operating frequency of the first radio when a determination is made that the individual or vehicle is exhibiting unusual behavior; and communicating a wireless signal of a second type from the first radio when the individual or vehicle is exhibiting unusual behavior, where the second type is different than the first type.

    摘要: In a fire alert system energy is harvested from a wire line pair (408) used to provide primary electrical power from a fire panel central monitoring station to a plurality of remote devices (406). The fire panel central monitoring station begins communications with a remote device by modulating the voltage on the wire line pair so as to communicate a first message (502) to one of the plurality of remote devices. Thereafter, one of the remote devices will respond to the first message with a second message (504) by modulating the voltage on the line pair. Energy is selectively harvested from the wire line pair at one or more of the remote devices in accordance with the remote device address specified in the first message.
