A motion detection unit is configured to detect motion of an object in the field of view of a camera. A processor is configured to identify a region of video data captured by the camera that includes the motion of the object. A determination unit is configured to determine perimeter data that represents at least a portion of a perimeter of the region of the video data. A combining unit is configured to combine the perimeter data with a video feed captured by a different camera. ## Claims ### Claim 1 A surveillance apparatus comprising: one or more processors configured to execute instructions that, when executed by the one or more processors, cause the one or more processors to: detect a moving object in a field of view of a first camera; identify a region of the moving object in a first video captured by the first camera; determine a perimeter of the region of the moving object in the first video, the perimeter tracing a shape of the moving object in the first video; overlay the perimeter of the region of the moving object in the first video on a second video captured by a second camera which is different from the first camera; and output the second video, which is captured by the second camera and is to be displayed on a display, on which the perimeter tracing the shape of the moving object in the first video captured by the first camera is overlaid, wherein an interior region of the perimeter overlaid on the second video is semi-transparent, and wherein a type of the moving object is identified from the shape that is represented by the perimeter, for controlling display of the perimeter tracing the shape of the moving object based on the identified type. ### Claim 2 (depends on 1) The surveillance apparatus according to claim 1, wherein: the perimeter of the region of the moving object in the first video and the region of the first video are overlaid on the second video to be displayed on the display. ### Claim 3 (depends on 1) The surveillance apparatus according to claim 1, wherein: the perimeter of the region of the moving object in the first video and identification of the first camera are overlaid on the second video to be displayed on the display. ### Claim 4 (depends on 1) The surveillance apparatus according to claim 1, wherein: the perimeter or an interior region of the perimeter, from the first video captured by the first camera, serves as a shortcut to displaying the first video. ### Claim 5 (depends on 1) The surveillance apparatus according to claim 1, wherein the instructions further cause the one or more processors to: detect a further moving object in a field of view of a further camera; identify a further region of the further moving object in a further video captured by the further camera; determine a further perimeter of the further region of the further moving object in the further video; and overlay the further perimeter on the second video captured by the second camera. ### Claim 6 (depends on 5) The surveillance apparatus according to claim 5, wherein the instructions further cause the one or more processors to be configured so that a selection can be made of how the one or more processors should combine the perimeter and the further perimeter with the second video captured by the second camera, when the parameter and the further parameter overlap. ### Claim 7 (depends on 1) The surveillance apparatus according to claim 1, further comprising at least one of: a server configured to perform processing of the first video captured by the first camera that includes the moving object, to determine that motion has been detected; and a motion sensor configured to inform the server that motion has been detected. ### Claim 8 (depends on 1) The surveillance apparatus according to claim 1, wherein the perimeter tracing the shape of the moving object in the first video overlaps with the second video for displaying, even if any moving objects are not present in the second video. ### Claim 9 A surveillance method comprising: detecting a moving object in a field of view of a first camera; identifying a region of the moving object in a first video captured by the first camera; determining a perimeter of the region of the moving object in the first video, the perimeter tracing a shape of the moving object in the first video; overlaying the perimeter of the region of the moving object in the first video on a second video captured by a second camera which is different from the first camera; and outputting the second video, which is captured by the second camera and is to be displayed on a display, on which the perimeter tracing the shape of the moving object in the first video captured by the first camera is overlaid, wherein an interior region of the perimeter overlaid on the second video is semi-transparent, and wherein a type of the moving object is identified from the shape that is represented by the perimeter, for controlling display of the perimeter tracing the shape of the moving object based on the identified type. ### Claim 10 A non-transitory computer-readable medium storing a program that, when implemented by a surveillance apparatus, causes the surveillance apparatus to perform a surveillance method comprising: detecting a moving object in a field of view of a first camera; identifying a region of the moving object in a first video captured by the first camera; determining a perimeter of the region of the moving object in the first video, the perimeter tracing a shape of the moving object in the first video; overlaying the perimeter of the region of the moving object in the first video on a second video captured by a second camera which is different from the first camera; and outputting the second video, which is captured by the second camera and is to be displayed on a display, on which the perimeter tracing the shape of the moving object in the first video captured by the first camera is overlaid, wherein an interior region of the perimeter overlaid on the second video is semi-transparent, and wherein a type of the moving object is identified from the shape that is represented by the perimeter, for controlling display of the perimeter tracing the shape of the moving object based on the identified type.
