Nyob rau hauv lub sijhawm tam sim no ntawm cov ntaub ntawv siv thev naus laus zis heev, cov neeg tuaj yeem yog eavesdropped txhua lub sijhawm thiab nyob txhua qhov chaw, yog li nws yog qhov tshwj xeeb tiv thaiv tus kheej ntiag tug. Cov cuab yeej kaw cia yog ib qho kev tiv thaiv kev tiv thaiv ntiag tug. Daim ntawv no yuav qhia cov txheej txheem technical thiab kev thov cov cim ntawm cov jammer kaw.
Cov txheej txheem ntawm cov sau jammer
Teev cov jammer yog hom khoom siv hluav taws xob, nws cov ntsiab lus cuam tshuam nrog cov cuab yeej kaw cia, kom cov khoom siv kaw cia tsis tuaj yeem sau suab nrov. Nyob rau hauv cov ntaubntawv povthawj siv Jammer, cov zaus muaj kev cuam tshuam ntau tshaj oscillator, thiab tau nthuav tawm los ua kom nws cuam tshuam nrog kev cuam tshuam ntau.
Tus txheej txheem ua hauj lwm ntawm cov ntaub ntawv kaw cia ntawm cov jammer tuaj yeem muab faib ua ob txoj hauv kev:
Ib qho yog dhau los ntawm ntau tiam ntawm ultrasonic sib xyaw technology, los ntawm cov built-in ultrasonic transducer los tshem tawm ntau yam ntawm ultrasonic tsis muaj kev xav los ntawm tib neeg lub pob ntseg rau kev sib xyaw. Cov sib xyaw ua ke ultrasonic tsis yog dab los ntawm huab cua los ua cov nquag uas tuaj yeem khaws tau los ntawm lub xov tooj ntawm tes, sau cov khoom siv xwj thiab lwm cov khoom lag luam digital. Cov kev taw qhia ultrasonic yog muaj zog, qhov kev sib kis nrawm yog qhov loj, yog li kom cov suab kaw lus tsuas yog "Buzz" suab nrov, yog li kom zam cov ntaub ntawv xau.
Ultrasound yog ib feem ntawm lub suab yoj, yog tib neeg pob ntseg tsis tuaj yeem hnov, ua suab nrov ntau dua 20kHz suab nrov, thiab tsuas yog kis tau rau hauv nruab nrab. Lwm tus yog los tsim cov cim siab-zaus, yog li ntawd lub microphone ntawm cov cuab yeej kaw cia tsis tuaj yeem tau txais cov teeb meem suab zoo li qub, yog li ua tiav cov cuam tshuam cuam tshuam. Ob txoj hauv kev tuaj yeem cuam tshuam nrog kev ua haujlwm ib txwm ntawm cov cuab yeej kaw cia kom ua tiav cov txiaj ntsig ntawm kev ntiag tug.
Daim Ntawv Thov Kev Ua Yeeb Yam Jammer
Sau cov jammers tuaj yeem siv rau hauv ntau qhov xwm txheej, feem ntau yog suav nrog cov hauv qab no:
Kev Sib Tham Kev Lag Luam: Scene Kev Sib Tham Kev Tsis Txaus Siab, thiab cov Jammer khaws cia kom tiv thaiv cov txheej txheem kev sib ceg los ntawm kev sib ceg. Yog li, kev sib tham ua lag luam yog ib qho ntawm cov ntawv thov feem ntau ntawm cov ntaubntawv jamers.
Kev tiv thaiv tus kheej ntiag tug: nyob rau qee qhov chaw pej xeem lossis chaw sau cia, cov chaw haujlwm, kev siv tsheb, thiab lwm yam.
Chav sib tham tim sablaj: chav sib tham yog ib qho ntawm cov ntawv tsis pub lwm tus paub hauv chav ua haujlwm tuaj yeem tiv thaiv cov ntaub ntawv tsis pub lwm tus paub los ntawm kev xau.
Cov Koom Haum Txawj Ntse: eavesdropping thiab anti-eavesdropping Technology yog ib feem tseem ceeb ntawm cov koom haum kev txawj ntse. Ua ib hom anti-eavesdropping Technology, suab Jammers tuaj yeem pab cov koom haum ntse tiv thaiv kev ruaj ntseg ntawm cov ntaub ntawv tseem ceeb.
Kev tshawb fawb tshawb fawb: Hauv qee qhov kev tshawb fawb tshawb fawb, nws yog qhov tsim nyog los sau cov txheej txheem sim rau cov ntaub ntawv tshawb xyuas txuas ntxiv. Txawm li cas los xij, yog hais tias cov txheej txheem sim yog sau tseg tsis raug kaw tseg lossis raug nyiag, nws yuav qhia tau cov ntaub ntawv tseem ceeb thiab kev tshawb fawb ntawm kev sim, ua rau kev sim ua nws qhov tseem ceeb. Yog li ntawd, hauv kev tshawb fawb tshawb fawb, siv cov ntaubntawv kaw cia tuaj yeem tiv thaiv cov txheej txheem sim los yog sau tseg, thiab tiv thaiv kev zais ntshis ntawm cov kev tshawb fawb.
Kev sib tham ua lag luam: Hauv kev sib tham ua lag luam, ob tog yuav pauv cov phiaj xwm kev lag luam, yog tias cov txheej txheem sib tham yuav xau, ua rau kev sib tham tsis raug cai, ua rau kev sib koom ua lag luam, ua rau kev sib koom tes ua lag luam. Kev siv cov ntaubntawv povthawj siv tawm tau zoo tiv thaiv kev sib hais ua lag luam los ntawm kev nyiag lossis kaw cia, thiab tiv thaiv kev ruaj ntseg ntawm cov kev lag luam zais ntshis.
Kev tiv thaiv tus kheej ntiag tug xws li Cafes, cov tsev noj mov thiab lwm qhov kev ceev ntiag tug, xws li raug nyiag los ntawm lwm cov txhab nyiaj hauv txhab nyiaj, tus kheej cov ntaub ntawv ntiag tug. Kev siv cov ntaubntawv povthawj siv tau zoo tiv thaiv tus kheej ntiag tug los ntawm eavesdropped thiab xyuas kom meej kev nyab xeeb ntiag tug.
Tag nrho cov nyob rau hauv tag nrho cov no, ib tug jammer yog ib qho cuab yeej zoo uas tuaj yeem txhim kho kev ceev ntiag tug. Nws tuaj yeem yog qhov dav hauv ntau qhov xwm txheej xws li tsev, chaw haujlwm thiab cov chaw pej xeem muab peb cov kev tiv thaiv zoo.
