Abstract

A method and system for installation of a monitoring unit. The monitoring unit comprises a photosensitive sensor for recording images of a monitored location. The system further comprises a light emitting element. The monitoring unit is arranged to detect the position of the light emitting element in a recorded image and by means of said position specify a sub-location within the monitored location.

Claims

1. A system for installation of a monitoring unit comprising a photosensitive sensor for recording images of a monitored area, said system comprising a light emitting element, and wherein the monitoring unit is arranged to detect the position of the light emitting element in a recorded image and by means of said position specify a sub-location within the monitored area.

2. A system according to claim 1, wherein the monitoring unit further comprises a means for receiving a signal comprising information identifying said position.

3. A system according to claim 2, wherein said means for receiving and the photosensitive sensor consist of one and the same component.

4. A system according to claim 1, further comprising a remote arrangement comprising a means for sending, which is arranged to emit a signal to the monitoring unit, which signal comprises information identifying said position.

5. A system according to claim 4, wherein the remote arrangement further comprises a key set, each key in the key set being associated with a determined position.

6. A system according to claim 5, wherein the key set is formed according to a determined pattern representing a sub-location of the monitored location, a key in the key set corresponding to a determined position by means of which the sub-location is specified.

7. A system according to claim 4, wherein the light emitting element is integrated with the remote arrangement.

8. A system according to claim 7, wherein the light emitting element and said means for sending consist one and the same component.

9. A system according to claim 8, wherein said component is a light emitting diode, particularly an IR light emitting diode.

10. A system according to claim 1, wherein the monitoring unit further comprises a memory arranged to store said detected position for later use in a control program.

11. A system according to claim 1, wherein the light emitting element is moveable in the monitored location.

12. A system according to claim 1, wherein the monitoring unit further comprises an indication element indicating that the position of the light emitting element is detected.

13. An arrangement for installation of a monitoring unit comprising a photosensitive sensor for recording images of a monitored location, comprising a means for sending, arranged to emit a signal containing information identifying a position in a recorded image, which position specifies a sub-location within the monitored location.

14. An arrangement according to claim 13, further comprising a key set, a key in the key set being associated with said position.

15. An arrangement according to claim 14, wherein the key set is formed according to a determined pattern representing a sub-location of the monitored location, a key in the key set corresponding to a determined position by means of which the sub-location can be specified.

16. An arrangement according to claim 15, further comprising a light emitting element.

17. A monitoring unit comprising a photosensitive sensor arranged to record images of a monitored location, comprising a processing unit arranged to detect the position of a light emitting element in a recorded image and by means of this position specify a sub-location of the monitored location.

18. A monitoring unit according to claim 17, further comprising a means for receiving a signal containing information identifying said position.

19. A monitoring unit according to claim 18, wherein said means for receiving and the photosensitive sensor consist of one and the same component.

20. A monitoring unit according to claim 19, further comprising a memory arranged to store said position for later use in a control program.

21. A monitoring unit according to claim 20, further comprising an indication element indicating that the position of the light emitting element is detected.

22. A method for installation of a monitoring unit comprising a photosensitive sensor for recording images of a monitored location, comprising:

recording at least one image of the monitored location and in the recorded image detecting the position of a light emitting element included therein and also by means of said position specifying a sub-location of the monitored location.

23. A method according to claim 22, further comprising:

storing said position for later use in a control program.

24. A method according to claim 23, further comprising:

indicating that the position of the light emitting element is detected.

25. A method according to claim 24, further comprising:

placing a light emitting element at a position, which contributes to specifying a sub-location within the monitored location.

26. A method according to claim 25, wherein the light emitting element in turns is placed at different positions and wherein the positions of the light emitting element detected in each recorded image are used together to specify said sub-location.

27. A method according to claim 26, further comprising the step of receiving in the monitoring unit a signal containing information identifying said position.

28. A computer program product comprising program code, which when input in a memory and executed by a processor executes the method according to claim 22.

29. Use of a remote arrangement for installation of a monitoring unit according to the method in claim 22.
