Lub tsev intercom systems yuav muab faib ua analog systems, digital systems thiab SIP systems raws li hom tshuab. Yog li yuav ua li cas cov neeg siv xaiv ntawm peb lub tshuab?Cov hauv qab no yog kev qhia txog peb lub tshuab rau cov neeg siv xaiv los ntawm kev siv.
1 Analog intercom system
Qhov zoo:
Tus nqi qis: cov cuab yeej siv qis thiab tus nqi tsim khoom, tsim nyog rau cov haujlwm me me nrog cov peev nyiaj tsawg.
Mature technology: cov kab ruaj khov, kev saib xyuas yooj yim, tus nqi qis qis.
Kev ua tau zoo ntawm lub sijhawm tiag tiag: tsis muaj kev ncua hauv kev xa xov, kev hu xov tooj ruaj khov.
Qhov tsis zoo:
Ib leeg muaj nuj nqi: tsuas yog txhawb nqa yooj yim hu thiab xauv, thiab tsis tuaj yeem nthuav cov haujlwm ntse (xws li yees duab, tswj chaw taws teeb).
Complex thaiv: suab thiab video cables thiab fais fab cables yuav tsum tau muab tso rau nyias, thiab expansion los yog transformation yog nyuaj.
Tsis zoo los tiv thaiv kev cuam tshuam: raug cuam tshuam rau electromagnetic cuam tshuam (xws li cov khoom siv hluav taws xob muaj zog), kev sib kis mus ntev teeb liab attenuation yog pom tseeb.
Tsis zoo scalability: tsis tuaj yeem koom ua ke nrog lwm lub tshuab (xws li kev tswj xyuas kev nkag, saib xyuas).
Cov xwm txheej uas siv tau: tus nqi qis qis xws li cov zej zog qub thiab cov tsev nyob me me.
Digital intercom system (IP intercom)
Qhov zoo:
Kev ua haujlwm nplua nuj: txhawb kev ua yeeb yaj kiab siab, kev qhib cov chaw taws teeb, cov ntaub ntawv tso tawm, hluav taws xob cat-qhov muag thiab lwm yam kev txawj ntse.
Kev xaim yooj yim: Xa los ntawm Ethernet (PoE fais fab mov) lossis Wi-Fi, txo cov nqi cable.
Muaj zog scalability: tuaj yeem koom ua ke tswj kev nkag mus, saib xyuas, tswb thiab lwm lub tshuab, txhawb nqa xov tooj ntawm tes APP tswj.
Muaj zog tiv thaiv kev cuam tshuam: cov teeb liab kis tau tus mob ruaj khov, haum rau cov zej zog loj lossis kev xa mus ntev.
Qhov tsis zoo:
Tus nqi siab: kev nqis peev loj hauv cov cuab yeej siv thiab kev tsim kho network (switches, routers).
Nyob ntawm lub network: kev ruaj ntseg network ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub cev, thiab bandwidth thiab kev ruaj ntseg yuav tsum tau lav.
Complex configuration: kev paub network paub debugging yog yuav tsum tau, thiab cov pib txij nkawm yog siab.
Cov xwm txheej siv tau: nruab nrab-rau-siab-kawg tsev nyob, cov tsev lag luam, cov zej zog ntse thiab lwm yam xwm txheej uas yuav tsum muaj kev sib koom ua ke ntau yam.
SIP intercom system (raws li VoIP raws tu qauv)
Qhov zoo:
Kev sib raug zoo siab: Raws li tus qauv SIP raws tu qauv, nws tuaj yeem txuas nrog cov kev sib txuas lus tseem ceeb (xws li IPPBX, softphone).
Kev sib txuas ntawm tej thaj chaw deb: Txhawb kev hu xov tooj rau tej thaj chaw deb ntawm Is Taws Nem (xws li kev sib txuas cov khoom vaj khoom tsev nrog cov neeg nyob hauv lub xov tooj ntawm tes).
Kev xa tawm yooj yim: Tsis tas yuav muaj cov cuab yeej tshwj xeeb, thiab tus IP network uas twb muaj lawm yog siv ncaj qha los txo cov nqi xaim.
Scalability: Yooj yim rau kev koom ua ke nrog lwm yam SIP terminals (xws li kev sib tham hauv video, chaw hu xov tooj).
Qhov tsis zoo:
Nyob ntawm lub network zoo: Kev ncua lossis tsis txaus bandwidth tuaj yeem ua rau hu xov tooj kaw thiab cov yeeb yaj kiab tsis pom tseeb.
Kev nyab xeeb kev nyab xeeb: Firewalls, encryption thiab lwm yam kev ntsuas yuav tsum tau teeb tsa los tiv thaiv kev tawm tsam hauv network (xws li eavesdropping, DoS).
Tus nqi hloov pauv: Yog tias yuav tsum muaj kev ruaj ntseg siab lossis QoS lav, cov nqi xa tawm tuaj yeem nce ntxiv.
Cov xwm txheej uas siv tau: Cov xwm txheej uas xav tau kev nkag mus rau thaj chaw deb lossis kev koom ua ke nrog kev sib txuas lus hauv tuam txhab (xws li cov tsev ua haujlwm, tsev kho mob, tsev kawm ntawv).
Cov lus qhia xaiv cov neeg siv:
Cov peev nyiaj tsawg, cov haujlwm yooj yim: xaiv qhov system analog.
Kev txawj ntse, kev nthuav dav yav tom ntej: xaiv digital intercom system.
Kev tswj chaw taws teeb lossis kev koom ua ke nrog kev lag luam: xaiv SIP system.
Hauv kev xa tawm tiag tiag, ib puag ncig network, muaj peev xwm tom qab tu thiab cov neeg siv xav tau yuav tsum tau txiav txim siab
