A personal security system comprising a portable actuator (10) and a controller (20) installed in a vehicle (100). The actuator (10) is operable to produce a distress signal which, when received by the controller (20), causes the controller to operate one or more of the vehicles door locks, siren (36) and/or interior light (30). The controller (20), after receiving the distress signal, ascertains whether or not the actuator (10) is inside or outside the vehicle (100) by monitoring the condition of the vehicle's electrical system and the condition of the vehicle's doors. Operation of the door locks, siren (36) and interior light (30) differs depending upon whether the actuator (10) is inside or outside the vehicle (100). |
