Techniques are described for replacing a keypad of an existing security system within a property with a communication-enabled keypad device with dual functioning capabilities as a communicator device and a keypad device. In some implementations, data is received from a security panel of a property. A keypad bus protocol of the security panel is determined based on the data received from the security panel. Sensor data is received from one or more sensors located within the property. A monitoring system command that is not specified within a keypad bus of the security panel is determined based on based on the obtained sensor data. The monitoring system command is converted to a panel command using the keypad bus protocol. The panel command is transmitted on the keypad bus of the security panel.

Methods, apparatuses, and embodiments related to a technique for changing topology of a wireless network in a multi-band wireless networking system. In a wireless network with multiple wireless networking devices and one or more client devices, communications between the wireless networking devices occurs via a backhaul channel, and communication between the client(s) and the wireless networking devices occurs via a fronthaul channel. At boot up, a wireless networking device configures the wireless network with a certain topology. After the topology is initially configured, the wireless networking device determines a network-related parameter and changes the topology of the wireless network based on the network-related parameter.

A method for presence detection in an environment to be monitored, includes generating an electric charge signal in a condition of absence of presence in the environment to be monitored. An electric charge signal is generated in an operating condition in which a person may be present in the environment. The two generated signals are processed and the results of the processing are compared. Processing the signals includes representing in a biaxial reference system the value of the charge signal considered and its derivative with respect to time, and identifying a plurality of points in the reference system. By comparing the position of the points acquired during the possible human presence with those of the base shape, a variation indicating the actual human presence may be detected. In this case an alarm signal is generated.
