Abstract (en)
Provided is a premises security monitoring system comprising a system control unit and at least one sensor node to detect security events, each sensor node including a first transceiver to receive control signals from, and to report security events to, the control unit. The control unit is configured to operate as an access point for a Wi-Fi network. At least one of the sensor nodes is powered by an autonomous power supply and includes, in addition to the first transceiver, a Wi-Fi transceiver for communication with the control unit over the Wi-Fi network.The control unit being configured to respond to a report of a security event by reporting the security event to a remote monitoring station, sending an instruction to the first transceiver of the autonomously powered node for the autonomously powered node to activate its Wi-Fi transceiver to transmit Wi-Fi signals that function as illumination signals in a Wi-Fi sensing function for a sensing area of the premises. The control unit activates the Wi-Fi sensing function for the sensing area and uses Wi-Fi illumination signals transmitted by the autonomously powered node in the Wi-Fi sensing function to perform a determination of whether there is human presence in the sensing area. The control unit then transmits the result of the determination to the remote monitoring station.
