4G GSM Video Intercom System
4G Video intercoms siv cov ntaub ntawv sim daim npav los txuas nrog cov kev pabcuam tuav kom xa video hu rau cov apps hauv xov tooj ntawm tes, ntsiav tshuaj, thiab IP video xov tooj.
3G / 4G LTE Intercoms ua tau zoo heev vim tias lawv tsis txuas nrog ib qho xov hlau / cables li no tshem tawm cov kev puas tsuaj los ntawm cable faults thiab yog qhov kev daws teeb meem zoo tshaj plaws rau cov cuab yeej cuab tam, cov chaw nyob deb, thiab kev teeb tsa qhov twg cabling tsis ua tau lossis kim heev rau nruab.The 4G GSM video intercom lub luag haujlwm tseem ceeb yog video intercom, qhib qhov rooj txoj kev (PIN code, APP, QR code), thiab portrait detection tswb. Lub walkie-talkie muaj cov ntaub ntawv nkag thiab cov neeg siv nkag nkag. Cov cuab yeej muaj lub vaj huam sib luag aluminium alloy nrog IP54 splash-proof. SS1912 4G qhov rooj video intercom tuaj yeem siv rau hauv cov tsev qub, lub tsev of elevator, factories lossis chaw nres tsheb.
Cov yam ntxwv daws teeb meem
4G GSM intercom system yooj yim nkag mus thiab tawm - tsuas yog hu rau tus lej thiab lub rooj vag qhib. Xauv lub kaw lus, ntxiv, tshem tawm thiab tshem tawm cov neeg siv tau yooj yim siv txhua lub xov tooj. Cov cuab yeej siv xov tooj ntawm tes muaj kev nyab xeeb dua thiab yooj yim rau kev tswj hwm thiab tib lub sijhawm tshem tawm qhov xav tau siv ntau yam, tshwj xeeb rau cov chaw taws teeb tswj thiab cov ntawv tseem ceeb. Thiab txij li tag nrho cov xov tooj tuaj tsis teb los ntawm GSM chav tsev, tsis muaj nqi hu rau cov neeg siv. Intercom system txhawb VoLTE, nyiam kev hu xov tooj kom meej dua thiab kev sib txuas hauv xov tooj sai dua.
VoLTE (Voice over Long-Term Evolution lossis Voice over LTE, feem ntau hu ua lub suab hais lus siab, kuj txhais tau hais tias lub suab hloov mus sij hawm ntev) yog tus qauv kev sib txuas lus ceev ceev rau cov xov tooj ntawm tes thiab cov ntaub ntawv terminals.
Nws yog raws li IP Multimedia Subsystem (IMS) network, uas siv cov profile tshwj xeeb tsim rau lub dav hlau Tswjhwm thiab xov xwm dav hlau ntawm lub suab pabcuam (txhais los ntawm GSM Association hauv PRD IR.92) ntawm LTE. Qhov no tso cai rau lub suab kev pabcuam (tswj thiab txheej txheej xov xwm) xa tawm raws li cov ntaub ntawv kwj hauv LTE cov ntaub ntawv tus neeg nqa khoom network yam tsis tas yuav tsum tau tswj hwm thiab tso siab rau ib txwm hloov pauv lub suab sib txuas.
