Abstract
A remote intrusion detection radio appliance includes a housing having a passive motion detector and related circuitry to monitor and warn of unwanted intrusions, by operating an external radio unit or cellular telephone plugged into the appliance. The appliance, when activated, broadcasts an audio output and then monitors an area in which it is located by audio and/or video for an intruder.
