【摘要】：隨著電子監(jiān)控技術(shù)的發(fā)展,各種各樣的監(jiān)控設(shè)備已經(jīng)融入了日常生活中,這些監(jiān)控設(shè)備在案件偵查、防盜等領(lǐng)域有著重要的作用。然而,在某些情況下也會有危害作用,不法分子也將微型攝像設(shè)備用于盜竊商業(yè)機(jī)密,竊取個人隱私。本文在研究電子設(shè)備輻射的基礎(chǔ)上,根據(jù)攝像頭特有的VLF頻段的輻射特征,提出了 一種利用該特征的攝像頭檢測技術(shù),以及設(shè)計出了一款利用此技術(shù)的設(shè)備并通過實驗驗證其效果。在各種環(huán)境下的測試結(jié)果表明,此技術(shù)可以實現(xiàn)較遠(yuǎn)距離的攝像頭檢測,并且根據(jù)原理可以利用手機(jī)磁場傳感器進(jìn)行一定程度的檢測。因此本技術(shù)在保護(hù)個人隱私、商業(yè)機(jī)密,以及博物館等不允許拍攝的場合均能有良好表現(xiàn),在今后可以有諸多重要的應(yīng)用場景可以發(fā)揮其作用。
[Abstract]:With the development of electronic monitoring technology, all kinds of monitoring equipment have been integrated into the daily life. These monitoring devices play an important role in the field of case investigation, anti-theft and other fields. However, in some cases, it will also have a harmful effect. The illegal elements also set up a micro camera to steal commercial secrets and steal personal privacy. Based on the radiation of electronic equipment, based on the radiation characteristics of the VLF frequency band unique to the camera, a camera detection technique using this feature is proposed, and a device using this technology is designed and its effect is verified by experiments. The test results in various environments show that this technology can achieve a long distance. Camera detection, and based on the principle of a mobile magnetic field sensor for a certain degree of detection. Therefore, this technology in the protection of personal privacy, commercial secrets, and museums and other places do not allow shooting can be good performance in the future can have a number of important use of the scene can play its role.
