Abstract:
1. A portable security system, comprising: a base unit having a housing in which a controller, a wireless transmitter, a window/door sensor and a tamper sensor are disposed; an auxiliary unit in which the base unit is removably received; the window/door sensor responsive to a first actuator mounted on a window or door for sensing movement of the window or door and providing a window/door open signal to the controller upon sensing movement of the first actuator, the window/door sensor responsive to movement of a second actuator mounted on the auxiliary unit when the base unit is received in the auxiliary unit and generating a first tamper signal in response to movement of the second actuator that is provided to the controller; the tamper sensor, when the base unit has been mounted to an asset, sensing if the base unit is displaced away from the asset and generating a second tamper signal in response to sensing that the base unit is displaced from the asset that is provided to the controller; the auxiliary unit including a tamper sensor actuator, the tamper sensor actuator, when the base unit is received in the auxiliary unit and the auxiliary unit has been mounted to the asset, actuating the tamper sensor when the auxiliary unit is displaced from the asset so that the tamper sensor generates the second tamper signal.
