Abstract

Systems, apparatuses, and methods are described for the detection, following a trigger event, of a device that may be sending and/or receiving signals within a space associated with a wireless network. A wireless signal receiver may be activated and may identify the device by detecting transmissions from the device, such as WiFi, Bluetooth, cellular or other wireless transmissions. The wireless signal receiver may extract, without connecting the device to a local network, information from the transmission that may identify the device. The wireless signal receiver may send the information to an alarm monitor and may be placed in a dormant state.
