Wireless Detector for Illicit CATV Tapping

One of the basic applications of television is to give entertainment via cable. Cable companies provide their customers the channels that are broadcasted locally or internationally. Digital Cable TV is fast growing nowadays, but not all companies are ready to adapt to this technology. Analog transmission of cable is still available, however, it is prone to illicit tapping. This study was conducted to detect illicit connections on CATV (Cable Television) lines particularly on analog transmission of signal. The system was conducted on a laboratory scale setup. There was a miniature type CATV distribution line wherein there was a connection from the device to the line. If the system detects illicit connection, then it notifies the user via mobile application. The functionality test was performed to evaluate and validate if the system conforms to its desired tasks. The functions of the system under the evaluation test were a) detection of illicit connection, b) sending of data via Bluetooth and c) receiving of data of the mobile phone. Analysis of the data revealed that the system operated with its desired functions. The results of this study indicate that the developed system was reliable on its functions particularly on detecting illicit connections.
