Mobile telephone for detecting wireless camera signal

Abstract

Based on current mobile phone structure, a mixer, an oscillator and a filter are added into reception end of mobile phone to make signal of wireless video cameral transfer to reception frequency channel, like GSM, CSC or PCS frequency channel. The frequency conversion signals can be processed as signals of mobile phone, and is directly inputted into fundamental frequency processor. The frequency channel used by wireless video cameral is scanned and analyzed by mobile phone to detect if the wireless video cameral is in working.
