Abstract: The present invention relates to the technical field of privacy protection equipment and discloses an anti-sneak shot detector, comprising a housing mechanism, a main control circuit board, and infrared sensors, wherein a plurality of the infrared sensors are evenly distributed in the housing mechanism along a circumferential direction, the main control circuit board is accommodated in the housing mechanism and is respectively connected to the infrared sensors via signals, and on the housing mechanism and/or the main control circuit board are provided Indicators; and when an infrared sensor receives an infrared signal, an indicator in a direction of the infrared sensor responds accordingly. The present invention realizes automatic surrounding scanning of the environment to detect hidden cameras in the environment, and has better portability. And the present invention is suitable for people who often travel on business, women living alone, security personnel, and confidential institutions.

Abstract: A noise reduction structure between a power source and a fixing plate includes: a buffer member having a first opening through upper and lower faces of a body, upper lower portions of the buffer member respectively extending transversely to form upper and lower portion extensions with a gap therebetween; a rigid support portion includes an upper plate block having a second opening, a lower plate block having a third opening, and a stop block connecting the upper plate block and the lower plate block, the buffer member being embedded and engaged between the upper and lower plate blocks; a connecting member having a free end provided with an engagement portion engaged within the gap and a fixing end connected onto the fixing plate; and a fixing rod running through the power source, connecting and fixing the support portion and the power source, being separated from the fixing plate.
