The passed in array needs to be of minimum size of allCamerasCount .
        When the array size is larger than the allCamerasCount value, only the first elements
        up to allCamerasCount will be filled up. When the array size is smaller than the
        allCamerasCount value, an argument exception is thrown. When the array argument
        passed in is null, this call will throw a nullreference exception.
The return value indicates how many cameras are saved in the array.
