Claims:We claim:
1. A method for surveillance of an area of interest, the method comprising:
synchronizing, by a surveillance device, plurality of image capturing devices to observe simultaneously, the area of interest;
receiving, by the surveillance device, view port details of an area being observed by each of the plurality of image capturing devices;
obtaining, by the surveillance device, one or more images captured at intersection points of field of view of the plurality of image capturing devices, when the view port details received from each of the plurality of image capturing devices matches with pre-set view port details of the area of interest;
generating, by the surveillance device, a 3-D model of the area of interest using the one or more images received from each of the plurality of image capturing devices; and
observing, by the surveillance device, the 3-D model for detecting at least one of presence and absence of a new element, in the area of interest.
2. The method as claimed in claim 1, wherein the area of interest for each of the plurality of image capturing devices is pre-set by the surveillance device.

3. The method as claimed in claim 1 further comprises tracking, by the surveillance device, at least one of movements and intrusions of the new element, by redefining observing path of the plurality of image capturing devices, upon detecting the presence of the new element.

4. The method as claimed in claim 3 further comprises alerting, by the surveillance device, security personnel proximal to present position of the new element, to perform one or more actions.

5. The method as claimed in claim 3, wherein tracking at least one of the movements and the intrusions of the new element is terminated, when the new element has moved outside the area of interest.

6. The method as claimed in claim 1, wherein the 3-D model of the area of interest is formed by combining the one or more images obtained from each of the plurality of image capturing devices.

7. The method as claimed in claim 1, wherein the viewport details comprises co-ordinate and pixel details of the area being observed by the plurality of image capturing devices.

8. A surveillance device for surveillance of an area of interest, the surveillance device comprising:
a processor; and
a memory communicatively coupled to the processor , wherein the memory stores the processor-executable instructions, which, on execution, causes the processor to:
synchronize plurality of image capturing devices to observe simultaneously, the area of interest;
receive view port details of an area being observed by each of the plurality of image capturing devices;
obtain one or more images captured at intersection points of field of view of the plurality of image capturing devices, when the view port details received from each of the plurality of image capturing devices matches with pre-set view port details of the area of interest;
generate a 3-D model of the area of interest using the one or more images received from each of the plurality of image capturing devices; and
observe the 3-D model for detecting at least one of presence and absence of a new element, in the area of interest.
9. The surveillance device as claimed in claim 8, pre-sets the area of interest for each of the plurality of image capturing devices.

10. The surveillance device as claimed in claim 8 further tracks at least one of movements and intrusions of the new element, by redefining observing path of the plurality of image capturing devices, upon detecting the presence of the new element.

11. The surveillance device as claimed in claim 10 further alerts security personnel proximal to present position of the new element, to perform one or more actions.

12. The surveillance device as claimed in claim 10 terminates tracking at least one of the movements and the intrusions of the new element, when the new element has moved outside the area of interest.

13. The surveillance device as claimed in claim 8 combines the one or more images obtained from each of the plurality of image capturing devices to form the 3-D model of the area of interest.

14. The surveillance device as claimed in claim 8, wherein the viewport details comprises co-ordinate and pixel details of the area being observed by the plurality of image capturing devices.

15. A non-transitory computer readable medium including instructions stored thereon that when processed by at least one processor causes a surveillance device to perform operations comprising:
synchronizing plurality of image capturing devices to observe simultaneously, the area of interest;
receiving view port details of an area being observed by each of the plurality of image capturing devices;
obtaining one or more images captured at intersection points of field of view of the plurality of image capturing devices, when the view port details received from each of the plurality of image capturing devices matches with pre-set view port details of the area of interest;
generating a 3-D model of the area of interest using the one or more images received from each of the plurality of image capturing devices; and
observing the 3-D model for detecting at least one of presence and absence of a new element, in the area of interest.
