Abstract

A portable security system for monitoring an asset has one or more alarm sensors and a wireless transmitter/receiver that communicates via wireless communication with a host system. The portable security system is switchable between a disabled (partially powered) state and an enabled (fully powered state) in response to commands received from the host system. In an aspect, the portable security system has a plurality of alarm sensors which a user can separately activate and deactivate via the host system. In an aspect, the portable security system includes a base unit and an auxiliary unit. The base unit includes one or more of the alarm sensors that serves a dual purpose depending on whether the base unit is mated with the auxiliary unit. In an aspect, the host system can be utilized by multiple users to manage portable security systems associated with the respective users, including management by group. In an aspect, the host system notifies a user(s) of an alarm condition(s).

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.

2. The portable security system of claim 1 wherein the tamper sensor includes a plunger that, when the base unit is mounted on an asset, is moved to a depressed position in the housing and is urged out from the depressed position when the base unit is displaced from the asset, and a position sensor that senses whether the plunger is in the depressed position.

3. The apparatus portable security system of claim 2 wherein the tamper sensor actuator of the auxiliary unit includes a moveable element that contacts the plunger of the tamper sensor.

4. The portable security system of claim 1 wherein the tamper sensor includes a magnetic sensor and a plunger assembly that includes a plunger, a spring that urges the plunger outwardly from the depressed position, and a magnet on a proximal end of the plunger, the magnetic sensor disposed in the housing of the base unit, the magnetic sensor sensing when the magnet changes location with respect to the magnetic sensor when the plunger moves outwardly from the depressed position when the base unit is displaced from the asset and generating the second tamper signal in response thereto.

5. The portable security system of claim 4 wherein the window/door sensor includes a magnetic sensor and the actuator mounted on the auxiliary unit is a magnet.

6. The portable security system of claim 1 wherein the auxiliary unit includes a hinged cover on which the actuator is mounted, the hinged cover closed when the base unit is received in the auxiliary unit and the window/door sensor responsive to the actuator moving with respect to the window/door sensor when the hinged cover is opened and generating the first tamper signal in response to the hinged cover being opened.

11. The portable security system of claim 1 wherein the auxiliary unit is a passive infrared motion detector.

12. The portable security system of claim 1 wherein the auxiliary unit includes at least one battery cell.

13. The portable security system of claim 1 including a temperature sensor coupled to the controller.

7. The portable security system of claim wherein

when the base unit is mounted on the asset and the controller receives the window/door opening signal from the window/door sensor the controller generates an alarm message that the window or door has moved which alarm message is sent wirelessly wireless transmitter/receiver, and

wherein when the base unit is received in the auxiliary unit and the controller receives the first tamper signal from the window/door sensor the controller generates a tamper message that the base unit is being removed from the auxiliary unit which tamper message is sent wirelessly by the wireless transmitter/receiver.

8. The portable security system of claim 7 wherein when the controller receives the second tamper signal the controller generates a second tamper message that the portable security system is being removed from the asset which second tamper message is sent wirelessly by the wirelessly transmitter.

9. The portable security system of claim 8 further including a global positioning system module (“

GPS module”

) disposed in the housing and coupled to the controller, the controller obtaining from the GPS module location information of where the portable security system is located, which location information is sent wirelessly by the wireless transmitter with each alarm or tamper message.

10. The portable security system of claim 7 further including a global positioning system module (“

GPS module”

) disposed in the housing and coupled to the controller, the controller obtaining from the GPS module location information of where the portable security system is located, which location information is sent wirelessly by the wireless transmitter with each alarm or tamper message.

14. A portable security system, comprising:

a base unit having a housing in which a controller, a wireless transmitter and a tamper sensor are disposed;
