【摘要】：随着电子监控技术的发展,各种各样的监控设备已经融入了日常生活中,这些监控设备在案件侦查、防盗等领域有着重要的作用。然而,在某些情况下也会有危害作用,不法分子也将微型摄像设备用于盗窃商业机密,窃取个人隐私。本文在研究电子设备辐射的基础上,根据摄像头特有的VLF频段的辐射特征,提出了一种利用该特征的摄像头检测技术,以及设计出了一款利用此技术的设备并通过实验验证其效果。在各种环境下的测试结果表明,此技术可以实现较远距离的摄像头检测,并且根据原理可以利用手机磁场传感器进行一定程度的检测。因此本技术在保护个人隐私、商业机密,以及博物馆等不允许拍摄的场合均能有良好表现,在今后可以有诸多重要的应用场景可以发挥其作用。
[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.
