Description

Portable hidden camera detection device {Detecting apparatus for hidden camera}

The present invention discloses a portable hidden camera detection device.

Recently, with the development of electronic and optical technologies, the performance of cameras is improved and their sizes are gradually reduced. For example, after a hidden camera combining a micro-camera, a microphone, and a high-performance small wireless transmitter is installed in a place used by a large number of unspecified people, the behavior of spying on, recording, and recording the internal situation is rapidly increasing.

In particular, hidden cameras are frequently installed targeting places where privacy must be protected because body exposure is unavoidable, such as changing rooms at clothing stores, amusement facilities such as water parks, restrooms at various stores, and accommodations. The video taken by the victim is being leaked, causing enormous damage to the victim who became the target of the crime.

On the other hand, in order to detect a hidden camera, a separate detector must be used to detect the hidden camera. However, there is a problem in that even if a hidden camera is installed, it cannot be checked at all.

Accordingly, in recent years, services for inspecting privacy-invading factors such as hidden cameras have been developed targeting lodging establishments or places where body exposure is unavoidable, but users, hidden camera inspection companies, smart device applications, communication networks (servers), lodging There is a problem of having to go through complex steps that require linkage with businesses.

In addition, the privacy invasion element inspection service not only targets accommodations or amusement facilities that have requested the inspection, but also presents inspection results conducted before the time the user uses it, so there is always a risk of hidden camera installation due to time delay. It is a situation.

Accordingly, there is a demand for a device or system that can be easily carried by a user and immediately used anytime, anywhere to detect a hidden camera.

Referring to these drawings, the hidden camera detection device 100 of this embodiment is provided inside a housing 10 having a predetermined shape, and as shown, the housing 10 includes a body area 20 and an antenna area 20 ) can be distinguished. The hidden camera detection device 100 in the body area 20 includes an RF unit 110 that receives an RF signal and converts it into a digital signal, a digital unit 120 that detects an abnormal signal according to the converted digital signal, and a detected abnormality. An alarm unit 130 for notifying a user of a signal, a control unit 140 for receiving a user operation, a power connection unit 150 for receiving power from the outside, and a mounting unit 160 for mounting on an external device are provided, and the antenna area 30 The hidden camera detection device of ) is provided with an antenna unit 170 for receiving an external signal.

That is, the hidden camera detection device 100 of this embodiment includes the antenna unit 170, the RF unit 110, the digital unit 120, the alarm unit 130, the manipulation unit 140, the power connection unit 150, and the mounting unit 160. ). Here, the antenna unit 170, the RF unit 110, the digital unit 120, the alarm unit 130, the control unit 140, and the power connection unit 150 may be printed in a circuit form on a predetermined substrate, or may be an IC chip or receptacle. It can be mounted in the form of a lamp to form one module.

Specifically, the antenna unit 170 is configured to detect a wireless signal emitted from a hidden camera, and is disposed in a separate antenna area 30 different from the main body area 20 to prevent distortion of the detected signal. . The antenna unit 170 is a directional antenna and may be composed of various types of antennas, such as a coil structure antenna or a printed circuit board antenna. In addition, the antenna unit 170 detects the wifi signal (2.5G or 5G band) emitted from the transmitter (secret camera), and receives a strong signal when the transmitter is located adjacent to or facing the transmitter.

The RF unit 110 receives signals detected by the antenna unit 170 and converts them into digital signals through processes such as filtering, amplification, attenuation, and conversion, and is electrically connected to the antenna unit 170. For this purpose, the RF unit 110 includes an RF signal input terminal, a filter, an amplifier, a digital attenuator, and an A/D converter. For example, an RG-085 terminal can be used as an RF signal input terminal, a QPL9503 chip can be used as an amplifier, a QPC6713 chip can be used as a digital attenuator, and an HMC6713 chip can be used as an A/D converter. can be used

The digital unit 120 receives the detection signal converted into a digital signal and transmits an alarm signal to the alarm unit 130 when it is determined to be an abnormal signal so that the alarm unit 130 is driven. The digital unit 120 for this may include a main control unit (MCU) for determining whether there is an abnormality and transmitting an abnormality signal to the alarming unit 130 . At this time, the digital unit 120 may be configured to determine the abnormal signal when the signal transferred from the RF unit 110 is greater than or equal to a previously input reference signal.

The alarm unit 130 is configured to notify the user when an alarm signal is transmitted from the digital unit 120, and may include an LED lamp 131 and a buzzer 132. At this time, the alarm unit 130 is configured to vary the blinking speed or brightness of the LED lamp 131, the volume or repetition cycle of the buzzer 132, etc., according to the strength of the abnormal signal.

The control unit 140 is configured to receive user commands, and receives commands by providing a plurality of buttons through the housing 10 . The control unit 140 may include a power unit 141 , a mode selection unit 142 , and a sensitivity control unit 143 . The power unit 141 drives the on/off of the hidden camera detection device, the mode selection unit 142 selects the signal detection mode of the hidden camera detection device, and the sensitivity control unit 143 controls the attenuator inside the device. adjust the sensitivity of

In particular, the mode selection unit 142 of this embodiment may select the hidden camera detection device to run in the first mode or the second mode.

The first mode is a real-time mode, which detects a real-time signal currently emitted in the surroundings, and detects a real-time signal emitted from other devices such as a hidden camera as well as a wiretapping device. Through the first mode, the user can check that abnormal signals are being detected in real time by various devices around the current detection device. Therefore, in the first mode, signals of various intensities different from each other can be detected. The intensity of this signal may be transmitted to the user as the intensity of the LED lamp 131 and the buzzer 132 .

In addition, in general, hidden cameras use a frequency band of 2.4 GHz or 5.0 GHz as a wifi signal, but recently, a band outside this frequency range is also used. Therefore, in the first mode, the wifi signal of the hidden camera generated in such an unusual frequency band is also detected.

In the first mode, the signal received and amplified by the RF unit 110 is input to the detect circuit, and the output voltage is input again to the A/D converter to perform sampling at a rate of 7,000 times per second. In order to reduce the error of the sampled value, the final signal value is calculated after taking an average value through an average of 7 sampling times during a random time. At this time, the intensity of the input signal may be determined by Equation 1 below.

[Equation 1]

y=((x-0.2)/0.015)-60

(Here, y is the input signal (dB), and x is the output value of the Detect circuit.)

In the first mode, the intensity of the input signal is calculated according to Equation 1, and as the intensity of the input signal increases, the generation cycle of the alarm unit 130 is accelerated so that the user can recognize the intensity of the detected signal (RF signal). .

In addition, the second mode is a leveling mode, and in the second mode, the average number of sampling of the A/D converter value in the first mode is increased to 32 times or more for a certain period of time. Through the second mode, the user can confirm that an abnormal signal is detected by a hidden camera, especially around the detection device. In general, since a hidden camera communicates with a receiver using a wifi signal, the second mode detects the hidden camera by detecting the wifi signal. Therefore, the second mode relatively increases the number of times of sampling of the A/D converter value and averages them, thereby detecting a hidden camera by a wifi signal.

In this case, the signal analysis time is increased, but erroneous measurement due to peak values is prevented as much as possible. In addition, in the second mode, instead of adjusting the generation cycle of the alarm unit 130 according to the strength of the signal as in the first mode, the generation cycle of the alarm unit 130 is accelerated when a signal of a certain value or more is detected, so that the user is not disturbed. Allows detection of signals to be recognized.

In addition, the sensitivity control unit is configured to have an adjustment range of 0 to 30 dB, and is set to adjust by 5 dB per step to be adjustable from 0 to 6 steps. For example, the maximum RF gain of the hidden camera detection device may be set to 32 dB, which is similar to the free space loss when 1 meter falls based on 2.4G. Therefore, the reception distance (L) can be adjusted according to Equation 2 whenever the sensitivity control unit is adjusted by one step (5dB).

[Equation 2]

L = a + ²ⁿ

(Here, a is the receiving distance at maximum sensitivity, and n represents the adjustment level (0 to 6).)

That is, when the sensitivity of the attenuator is increased through the sensitivity control unit, the reception distance is reduced in proportion to Equation 2, and when the sensitivity of the attenuator is decreased, the reception distance is increased in proportion to Equation 2.

The power connector 150 is a component that receives power from an external device in real time. The external device may be a smart phone or a portable auxiliary battery, and is not limited thereto as long as it is portable and can supply power. In addition, the power connection unit 150 may be configured with various types of connection terminals such as USB, D-type, and C-type. Since the hidden camera detection device of this embodiment does not have a separate power storage device such as a battery inside by the power connection unit 150, the structure is simplified and has an advantageous effect on miniaturization and light weight.

The mounting unit 160 is a configuration for mounting and fixing the hidden camera detection device 100 to an external device. Likewise, the external device may be a smart phone or an auxiliary rechargeable battery, and is composed of a portable device capable of supplying power.

As shown in FIG. 2 , the mounting portion 160 may be composed of a magnetic member provided inside the housing 10 . In this way, when the mounting portion 160 is composed of a magnetic member, it can be placed inside the housing 10, thereby simplifying the appearance of the hidden camera detection device 100 and preventing interference between the mounting portion 160 and other devices. can

Also, although not shown, the mounting portion 160 may be composed of a suction pad provided on the surface of the housing 10 .
