AB  - The importance of security in today’s world cannot be overemphasized. It is therefore, imperative to
have a cheaper and lower resource requiring methods of achieving good security. Leaving home, work place,
a child or somewhere important that needs supervision unattended is now a days not safe. There
should be a form of supervision or surveillance either in person or by a machine. This research aimed at
designing an electronic based device to provide such surveillance by sensing and tracking a single
object in 3-Dimensional (3-D) motion within a defined space. Peering into the natural world it is found that
animals such as dolphins, owls and bats locate objects and prey using sound, some animals even sense
distortions in electromagnetic waves. Inspiration is not only garnered from nature but also from current
technologies for this research. Three electronic sensors namely passive infra-red, active infrared and ultrasonic
are evaluated and considered for designing a 3-D motion tracking system using mathematical method of vector
analysis. An extensive look into the workings and features of all thethree sensors was done in order to find
which sensor holds the greatest capacity for sensing an objects motion and obtaining the relative position of
an object by the sensor in 3-dimensional space. Once achieved, the process of measurement can be done
repeatedly at distinct time intervals to track the motion of the object in 3D space. The major benefit of this
research is for the security and surveillance of property or personnel but is not limited to this. There is also an
opportunity for applications in other areas such as in sports for tracking the 3D motion of an athlete and can
also assist in evaluating player statistics such as speed and acceleration.
