A portable security system 10 includes a control circuit 12 electrically connected with a motion sensor 14, an audible alarm 16 and a visual alarm 18. These components are held within a housing 20 which has a standard light globe/tube electrical connector 22 attached to one end 24 for allowing connection to mains power through a corresponding standard light globe/tube socket. A standard light globe 26 is demountably connected within the housing 20 to illuminate an area in the same manner as if the globe 26 were connected directly into the socket which receives the connector 22. A portable remote controller 28 switches the control circuit 12 between an ON state in which the control circuit is active to operate the audible and visual alarms 16, 18 upon detection of a moving body by the motion detector 14; and, an OFF state in which the control circuit deactivates the motion sensor 14 and allows the light globe 26 to be operated as a standard light globe by the switch for the socket to which the connector 22 is connected. Thus, the system 10 can be simply installed in an conventional light socket.
