MULTIZONE WALK THROUGH METAL DETECTOR WITH CAMERA & TEXT OVERLAY CHIP FOR MEASURING, DISPLAYING, TRANSFERRING DATA WITH VIDEO AND RECORDING THE PARAMETERS OF THE SYSTEM SYNCHRONIZED WITH THE VIDEO IMAGE IN COMPUTER

摘要

The invention is directed to a Walk through Metal Detector's detection data transferring & displaying methodology mixed with composite video signal and logging the data concerning the detection of the system superimposed on the video with time stamp. The invention includes a Microcontroller based portable computer having manual & automatic inputs coming from a data port. An auxiliary processor or module is used at the output side to superimpose the data with composite video signal coming from a camera output. The system data like Sensitivity, Thresh Hold and Metal Level, these three parameters are being displayed at a time for all the zones on a Alpha Numeric LCD /Graphic LCD and on the Monitor with the composite video signal to enable a comparative study of the zone detection.
