The intelligent wireless video camera described in this paper
is designed using wireless video monitoring system, for detecting the presence
of a person who is inside the restricted zone.
This type of automatic wireless video monitors is quite suitable for the
isolated restricted zones, where the tight security is required.
The
principle of remote sensing is utilized in this, to detect the presence of any
person who is very near to reference point with in the zone.
A video
camera collects the images from the reference points and then converts into
electronic signals. The collected images
are converted from visible light into invisible
electronic signals inside a
solid-state imager. These signals are
transmitted to the monitor,
In this paper
for the demonstration purpose three reference points are taken. Each reference point is arranged with two
infrared LED’s and one lamp. This
arrangement is made to detect the presence of a person who is near the
reference point. The reference point is
nothing but restricted area, when any person comes near to any reference point,
then immediately that particular reference point output will become high and
this high signal is fed to the computer.
Now the computer energizes that particular reference point lamp and
rotates the video camera towards that reference point for collecting the images
at that particular reference point. To rotate the video camera towards
interrupted reference point, stepper motor is used.
