Problems solved by technology

[0002] In recent years, there have been rumors in the society that people with hidden intentions use hidden pinhole cameras to install them in hotels, restaurants, or hostels, etc., secretly taking pictures of other people's privacy and then copying and selling them. privacy rights have been seriously violated, and hoteliers have also suffered
[0003] In order to curb this trend of sneak photography, hoteliers must detect the movement of sneak photography devices in every room from time to time, and this detection work is quite time-consuming and labor-intensive; in addition, the sneak photography devices are difficult to detect after being camouflaged, making the detection work in vain , these factors also make the hotel industry very troubled

Abstract

The system thereof comprises: at least one detector, at least one alarm unit, and at least one telephone line. Wherein, each detector has a RF receiver, a filter, a signal amplifier, a directly translating receiver, and a level translator; each alarm unit comprises a controller and an alarm device. The invention can detect a certain area to decide if there is an abnormal signal; if yes, then the detector can transmit an alarm signal to the alarm unit to trigger the alarm device.

Description

technical field [0001] The invention relates to a signal detection system, especially a signal detection system suitable for transmission by telephone lines. Background technique [0002] In recent years, there have been rumors in the society that people with hidden intentions use hidden pinhole cameras to install them in hotels, restaurants, or hostels, etc., secretly taking pictures of other people's privacy and then copying and selling them. The right to privacy has been severely violated, and hoteliers have also suffered. [0003] In order to curb this trend of sneak photography, hoteliers must detect the movement of sneak photography devices in every room from time to time, and this detection work is quite time-consuming and labor-intensive; in addition, the sneak photography devices are difficult to detect after being camouflaged, making the detection work in vain , These factors also make the hotel industry very disturbed. Contents of the invention [0004] The ob...
