identifying a spatial region, of the one or more spatial regions, that includes the target location;

controlling the camera to aim at the target location based on the one or more camera motor coordinates associated with the spatial region; and

controlling the camera to capture the media of the target location,

wherein the camera is a pan, tilt camera, and each of the one or more camera motor coordinates associated with each spatial region, comprises pan, tilt and rotation motor coordinates to aim the camera at the spatial region; and

controlling the camera to aim at the target location comprises:

determining the position of the target location within the spatial region,

identifying the pan and tilt motor coordinates for each corner of a quadrilateral defining the spatial region, and

determining pan and till coordinates for aiming the camera at the target location by interpolating between the pan and tilt motor coordinates for each corner of the spatial region based on the determined position of the target location within the spatial region.

3 . The method of claim 2 , wherein after aiming the camera at the target location, the method further comprises:

transmitting a real-time media stream from the camera to the user device, via the server.

4 . The method of claim 3 , further comprising dynamically adjusting the number of frames per second and the quality factor of each frame, in the real-time media stream, to minimize latency.

5 . The method of claim 3 , wherein the method further comprises:

receiving, from the user device, one or more commands for one or more camera adjustment operations;

in response to the media capture trigger, controlling the camera to capture the media of the target location.

7 . The method of claim 1 , wherein the media comprises one or more of an image, a burst of images and a digital video clip.

8 . The method of claim 1 , wherein each spatial region, defined in the camera-specific venue map, comprises a quadrilateral shaped area, and the one or more camera motor coordinates associated with each spatial region comprise pan and tilt coordinates for each corner of the quadrilateral.

9 . The method of claim 8 , wherein the camera is a pan-tilt-zoom (PTZ) camera, and the camera-specific venue map includes a zoom value associated with each spatial region, the zoom value defining a degree of zoom for the camera when the spatial region is within the camera's field of view.

10 . The method of claim 1 , wherein the venue includes a plurality of cameras, each camera having a corresponding camera-specific venue map, and selecting the camera to capture the media comprises:

determining a mapped spatial region range of each camera-specific venue map; and

selecting a camera having a mapped spatial region range that includes the target location.

11 . The method of claim 10 , wherein assigning the camera to capture the media comprises:

identifying at least two cameras having a mapped spatial region that includes the target location;

determining a request queue for each of the at least two cameras;

selecting the camera having the shortest request queue; and

assigning the media capture request to the selected camera queue.

12 . The method of claim 1 , initially comprising generating the camera-specific venue map by:

defining a plurality of spatial regions, each spatial region defining an area in the venue;

identifying a reference object within the spatial region range;

capturing camera motor coordinates for each corner of the spatial region and relative to the reference object.

13 . The method of claim 1 , wherein

the venue setting is one of a sports venue, a stadium, a mini-golf course, a bowling alley, a theater and a top golf course, and

the target venue location is one of a seat number, a box number, a bowling alley lane number and a golf course hole number.

14 . A system for automated control of cameras in a venue setting, the system comprising:
