Makina omanga ma intercom amatha kugawidwa m'makina a analogi, makina a digito ndi machitidwe a SIP malinga ndi mtundu waukadaulo. Ndiye kodi ogwiritsa ntchito amasankha bwanji pakati pa machitidwe atatuwa? Chotsatirachi ndi mawu oyamba a machitidwe atatuwa kuti ogwiritsa ntchito asankhepo ngati kalozera.
1 Analogi intercom system
Ubwino:
Mtengo wotsika: mtengo wotsika wa zida ndi mtengo woyika, oyenera mapulojekiti ang'onoang'ono okhala ndi bajeti yochepa.
Ukadaulo wokhwima: mizere yokhazikika, kukonza kosavuta, kulephera kochepa.
Kuchita mwamphamvu munthawi yeniyeni: osachedwetsa kufalitsa mawu, kuyimba kokhazikika.
Zoyipa:
Ntchito imodzi: imathandizira mafoni oyambira ndikutsegula, ndipo sangathe kukulitsa ntchito zanzeru (monga kanema, kuwongolera kutali).
Mawaya ovuta: zingwe zomvera ndi makanema ndi zingwe zamagetsi ziyenera kuyikidwa padera, ndipo kukulitsa kapena kusintha kumakhala kovuta.
Kusasokoneza kosagwirizana: kumatha kusokonezedwa ndi ma elekitiroma (monga zida zamphamvu zamagetsi), kutsika kwa ma siginecha atalitali ndizodziwikiratu.
Kusayenda bwino: sikungaphatikizidwe ndi machitidwe ena (monga kuwongolera, kuyang'anira).
Zochitika zogwiritsidwa ntchito: zotsika mtengo zofunidwa monga madera akale ndi nyumba zazing'ono zogona.
Digital intercom system (IP intercom)
Ubwino:
Ntchito zolemera: kuthandizira kanema wotanthauzira kwambiri, kutsegula kutali, kutulutsa chidziwitso, diso lamagetsi lamagetsi ndi ntchito zina zanzeru.
Mawaya osavuta: Amatumizidwa kudzera pa Ethernet (magetsi a PoE) kapena Wi-Fi, kuchepetsa mtengo wa chingwe.
Kukhazikika kwamphamvu: kumatha kuphatikiza kuwongolera, kuyang'anira, alamu ndi machitidwe ena, kuthandizira kuwongolera kwa APP yam'manja.
Kusokoneza mwamphamvu: Kutumiza kwa digito kumakhala kokhazikika, koyenera madera akuluakulu kapena kutumizidwa mtunda wautali.
Zoyipa:
Mtengo wokwera: kugulitsa kwakukulu pazida ndi ma network (ma switch, ma routers).
Kutengera maukonde: kukhazikika kwa maukonde kumakhudza mwachindunji magwiridwe antchito, ndipo bandwidth ndi chitetezo ziyenera kutsimikiziridwa.
Kukonzekera kovutirapo: Kuwongolera chidziwitso cha akatswiri pamanetiweki ndikofunikira, ndipo njira yokonza ndiyokwera.
Zochitika zogwiritsidwa ntchito: nyumba zokhalamo zapakatikati, zamalonda, midzi yanzeru ndi zochitika zina zomwe zimafuna kugwirizanitsa ntchito zambiri.
SIP intercom system (yotengera VoIP protocol)
Ubwino:
Kugwirizana kwakukulu: Kutengera ndi protocol ya SIP yokhazikika, imatha kulumikizidwa mosadukiza ndi njira zoyankhulirana zodziwika bwino (monga IPPBX, softphone).
Kulumikizana kwakutali: Imathandizira mafoni akutali kudzera pa intaneti (monga kulumikiza malo okhala ndi mafoni a m'manja).
Kutumiza kosinthika: Palibe zida zapadera zomwe zimafunikira, ndipo netiweki ya IP yomwe ilipo imagwiritsidwa ntchito mwachindunji kuchepetsa mtengo wama waya.
Scalability: Yosavuta kuphatikiza ndi ma terminals ena a SIP (monga misonkhano yamavidiyo, malo oyimbira foni).
Zoyipa:
Zimatengera mtundu wa netiweki: Kuchedwa kapena kusakwanira kwa bandwidth kumatha kuyambitsa kuyimba kwa mafoni ndi makanema osawoneka bwino.
Zowopsa zachitetezo: Zotchingira zozimitsa moto, kubisa ndi njira zina ziyenera kukonzedwa kuti ziteteze kuukira kwa netiweki (monga kumvetsera, DoS).
Kusintha kwamitengo: Ngati chitetezo chapamwamba kapena zitsimikizo za QoS zikufunika, ndalama zotumizira zitha kukwera.
Zochitika zogwiritsidwa ntchito: Zochitika zomwe zimafuna kupeza kutali kapena kuphatikizidwa ndi njira zoyankhulirana zamakampani (monga nyumba zamaofesi, zipatala, masukulu).
Zosankha zogwiritsa ntchito:
Bajeti yochepa, ntchito zosavuta: sankhani dongosolo la analogi.
Wanzeru, kukulitsa kwamtsogolo: sankhani makina amtundu wa digito.
Kuwongolera kutali kapena kuphatikiza ndi bizinesi yamabizinesi: sankhani dongosolo la SIP.
Pakutumizidwa kwenikweni, malo ochezera a pa intaneti, kuthekera kokonzanso pambuyo pake komanso zosowa za ogwiritsa ntchito ziyeneranso kuganiziridwa
