A portable security alarm system which can be installed on a temporary basis and removed from an object whose movement is to be detected including a motion detecting and radio signal transmitting member for mounting proximate the object whose movement is to be detected, a member for selectively coupling and decoupling the motion detecting and radio signal transmitting member relative to the object whose movement is to be detected, a combined radio signal receiving and alarm generating member for receiving a signal from the combined motion detecting and radio signal transmitting member and producing an alarm, a remote control for actuating and deactuating the radio signal receiving and alarm generating member, and components for providing object identification information identifying the object whose movement is to be detected and distance measurement information for measuring the distance moved by the object.
