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.
