Object for theft detection

1. A first object for theft detection of a second object, the second object being in pair with a third object for securing the second object, the first object comprising:

a detector for

detecting a second signal from the second object and a third signal from the third object when transmitted within a detection area of the detector, and

providing a detector output;

a controller for

identifying, by processing the detector output, a condition indicating both (i) a pairing of the second signal and the third signal, and (ii) the controller determining, from tracking a location of the second signal, that the second signal is leaving the detection area and that the third signal is not being detected within the detection area while the second signal is leaving the detection area, and

performing a theft detection action for protecting against theft of the second object in response to said identifying.

2. The first object according to claim 1 , wherein the controller is arranged for

identifying a pairing of the second signal and the third signal, when the second signal and the third signal are moving in pair into the detection area.

3. The first object according to claim 1 , wherein the controller is arranged for

accessing a pairing database comprising a list indicating whether the second signal and the third signal are a pair, and

identifying a pairing of the second signal and the third signal, when in the pairing database the second signal and the third signal are listed as a pair.

4. The first object according to claim 3 , further comprising a storage device for hosting the pairing database locally within the first object.

5. A system for theft detection comprising:

a first object comprising a detector and a controller;

a second object; and

a third object,

wherein the second object is in pair with the third object for securing the second object,

wherein the detector is configured to

detect a second signal from the second object and a third signal from the third object when transmitted within a detection area of the detector, and

provide a detector output, and

wherein the controller is configured to

perform an identification, by processing the detector output, of a condition indicating both (i) a pairing of the second signal and the third signal, and (ii) the controller determining, from tracking a location of the second signal, that the second signal is leaving the detection area and that the third signal is not being detected within the detection area while the second signal is leaving the detection area, and

perform a theft detection action for protecting against theft of the second object in response to said identification.

6. The system according to claim 5 , wherein the first object is part of a lighting infrastructure.

7. The system according to claim 5 , wherein the third object is a key device, smartphone or smart wearable device.

8. The system according to claim 5 , wherein the second object is a vehicle or electronics device.

9. The system according to claim 5 , the system further comprising

a pairing database comprising a list indicating whether the second signal and the third signal are a pair;

wherein the list is adjustable by an external input.

10. The system according to claim 5 , wherein the theft detection action comprises an action from the group of monitoring, sending a notification, outputting a visual alarm, outputting an audible alarm;

wherein the warning notification is sent to governmental institutions, security companies, a registered owner of the second object, the third object, or receivers further detected within the detection area during time of theft.

11. The system according to claim 5 , wherein the theft detection action comprises taking an image of the detection area or tracking the second signal.

12. A method performed by a first object for theft detection of a second object, the second object being in pair with a third object for securing the second object, the method comprising:

detecting, with a detector comprised within the first object and within a detection area of the detector, a second signal from the second object and a third signal from the third object;

providing a detector output of the detector to a controller;

identifying, with the controller, by processing the detector output, a condition indicating both (i) a pairing of the second signal and the third signal, and (ii) the controller determining, from tracking a location of the second signal, that the the second signal is leaving the detection area and that the third signal is not being detected within the detection area while the second signal is leaving the detection area;

performing a theft detection action for protecting against theft of the second object in response to said identifying.

13. A method according to claim 12 , wherein the method further comprises:

identifying, with the controller, a pairing of the second signal and the third signal, when the second signal and the third signal are moving in pair into the detection area.

14. A method according to claim 12 , wherein the method further comprises:

accessing, with the controller, a pairing database comprising a list indicating whether the second signal and the third signal are a pair, and

identifying, with the controller, a pairing of the second signal and the third signal, when in the pairing database the second signal and the third signal are listed as a pair.

15. A computer program product comprising computer program code stored on a non-transitory storage medium, wherein the program code is configured to cause a processor to perform the method of claim 12 when the computer program code is run by the processor.
