Khoom Taw Qhia

The "Concealed" Recording Shield is a highly integrated high-tech security product developed by AL ASAR TECH. When a criminal uses a recording device (such as a mobile phone, voice recorder, recorder, etc.) to record you, the recording mask produces a random noise signal that can suppress the interference of the voice signal, so that the recording device can only pick up Noise information, and can not distinguish voice information, thus ensuring the security of voice information.

Cov lus qhia rau kev siv

Tsim los ntawm

Cov khoom no siv ob hom kev siv fais fab: lub hwj chim adapter thiab roj teeb.

1. Thaum lub adapter yog powered. Tsuas yog ntsaws lub hwj chim adapter rau hauv lub hwj chim thiab them cov chaw nres nkoj ntawm daim duab 2.

2. Cov khoom no muaj 8000Mha roj teeb, uas yog siv rau lub hwj chim lub roj teeb tsis muaj hwj chim adapter.

Siv

Tom qab kuaj xyuas cov khoom, xyuas lub pob ua ntej: ib tus tswv tsev; ib qho chaw taws teeb tswj; ib lub hwj chim adapter

1. Qhib lub hwj chim hloov ntawm daim duab 2, lub hwj chim taw qhia teeb pom kev, thiab lub tshuab nkag mus rau hauv lub xeev standby;

2. Nias lub khawm qhib ntawm lub chaw taws teeb tswj kom qhib lub tshuab, nias lub xauv khawm ntawm lub chaw taws teeb tswj kom kaw lub tshuab thiab nkag mus rau lub xeev standby.

3. Tua lub hwj chim hloov hauv daim duab 2 thiab txiav lub hwj chim ntawm lub tshuab.

Faj seeb: Lub ua tau - loj- roj teeb muaj peev xwm muaj lub sij hawm ua hauj lwm ntau tshaj 19 teev. Nws raug nquahu kom siv lub roj teeb yog tias nws muaj hluav taws xob.

Raws li pom nyob rau hauv daim duab 1, lub transmitter yog nyob rau pem hauv ntej ntawm lub tshuab. Rau kev tiv thaiv zoo tshaj plaws, kho qhov chaw thiab lub kaum sab xis raws li qhov xwm txheej tiag tiag. Kom paub meej, saib daim duab 3. Raws li pom hauv daim duab 3, rau cov khoom siv kaw lus dav dav, qhov kev txiav tawm ntawm cov khoom no yog hais txog 1.5 meters, thiab lub kaum sab xis txiav yog li 90 degrees. Qhov kev ncua deb thiab lub kaum sab xis yuav txawv rau cov khoom siv sib txawv. Qee cov qauv muaj qhov deb ntau dua 2 meters thiab lub kaum sab xis siab dua 120 degrees, tab sis ob peb tus qauv yuav muaj qhov deb tsawg dua 1 meter thiab lub kaum sab xis ntawm tsawg dua 60 degrees.

The higher the end of the general model, the better the effect. When using, please try to make the distance between the transmitter's transmitting end and the recording device within 1.5 meters. The angle (mainly the MIC port) is within 45 degrees. The closer the distance is, the smaller the angle is, the better the cutting effect is.

Thov nco ntsoov tias cov ntaub ntawv saum toj no tau txais yam tsis muaj kev cuam tshuam ntawm lub transmitter thiab cov ntaub ntawv kaw lus (xws li khaub ncaws, lub cev, thiab lwm yam). Nyob rau hauv cov ntaub ntawv ntawm kev thaiv, qhov kev ncua deb yuav luv luv.

Lub kaw lus kaw siv lub siab - kev ruaj ntseg encryption algorithm los tsim random siab - lub zog cuam tshuam cov cim.

Qhov ntau zaus ntawm cov teeb liab cuam tshuam yog nyob rau hauv qhov tau txais ntau yam ntawm cov khoom khaws cia.

Thaum lub kaw lus kaw cov kaw lus tsis raug cai, tus nqa tuaj yeem nqa lub teeb liab cuam tshuam thaum khaws lub suab teeb liab.

Qhov kev siv ntawm lub teeb liab cuam tshuam yog ntau dua li lub suab teeb liab, thiab txawm tias tshaj qhov siab tshaj plaws tau txais lub zog pib ntawm qhov tuaj tos. Qhov no yuav ua rau muaj kev cuam tshuam tsis zoo rau lub suab teeb liab, thiab txawm tias ua rau lub tsheb thauj khoom tsis ua haujlwm ib txwm muaj, yog li cov neeg nqa khoom tuaj yeem khaws cov ntaub ntawv nrov nrov.

Lub teeb liab qhov chaw uas tsim cov teeb liab cuam tshuam yog ib qho encrypted random random ib ntus, yog li cov ntaub ntawv lub suab qub tsis tuaj yeem rov qab los ntawm cov thev naus laus zis ntsig txog, thiab lub hom phiaj ntawm kev tiv thaiv lub suab cov ntaub ntawv thiab tshem tawm cov kev phom sij zais ntawm eavesdropping tiav.
