Embodiment Construction

[0033] Usually the wireless camera signal is transmitted in the frequency band of 1.2GHz or 2.4GHz. This invention uses the mobile phone to scan this frequency band to detect the strength of the wireless camera signal, so as to know whether there are criminals using the wireless camera to monitor or secretly take pictures nearby. . The design of the present invention makes full use of the existing main structures of mobile phones on the market, and only needs to add a filter (filter) and a mixer (mixer) at the receiving end, and a voltage control oscillator (Voltage Control Oscillator; VCO) or Utilizing the original VCO in the mobile phone, the mobile phone function and the anti-candid camera detector function can be combined in the mobile phone body.

[0034] figure 1 A front-end structure of a mobile phone capable of detecting wireless camera signals according to a first embodiment of the present invention is shown. The mobile phone of the first embodiment of the present i...

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.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a mobile phone capable of detecting the signal strength of a wireless camera. Background technique [0002] Video cameras have become quite common electronic products in the market today, and there are also many small wireless cameras on the market. Using wireless communication technology, the pictures captured by the wireless camera are transmitted to multiple receivers as wireless signals. Therefore, there are a large number of tools that are often used for surveillance or sneak shooting, such as pinhole cameras, on the market, which pose a serious threat to people's privacy. At present, electronic products have developed and produced small portable anti-candid camera detectors, which can detect nearby pinhole cameras and wireless bugs and other radio wave emission sources at any time, so as to prevent personal or company private information from being threatened, effectively Guarantee the pr...
