VIRTUAL_FENCE_OBJECT

This union defines the geometry data used for configuring a Virtual Fence zone. It supports multiple shape types (cube, polygon, and cylinder) sharing the same memory region. Each substructure provides spatial limits or boundaries along X, Y, and Z axes.

BYTE#	Field Name	Data Type	Value	Remarks
0	_tCube	struct		Contains X/Y/Z upper and lower limits defining a rectangular prism region. - _fXLoLimit, _fXUpLimit - _fYLoLimit, _fYUpLimit - _fZLoLimit, _fZUpLimit
20	_tPolygon	struct		Defines a polygonal boundary using 2D line segments (LINE) and vertical limits (_fZLoLimit, _fZUpLimit). - _iLineCount : number of polygon edges (max 6) - _tLine[6] : line segments connecting each vertex
125	_tCylinder	struct		Represents a circular boundary with height limits. - _fRadius : cylinder radius - _fZLoLimit, _fZUpLimit : vertical limits
137	_iBuffer	unsigned char[110]		Reserved Space 10 bytes

Total size: 147 bytes
