Kupanga ma intercom system kungagawidwe m'ma analog system, ma digital system ndi ma SIP systems malinga ndi mtundu wa ukadaulo. Ndiye kodi ogwiritsa ntchito amasankha bwanji pakati pa ma system atatuwa? Izi ndi chiyambi cha ma system atatuwa kuti ogwiritsa ntchito asankhe ngati chitsogozo.
1 Dongosolo la analog intercom
Ubwino:
Mtengo wotsika: mtengo wotsika wa zida ndi mtengo woyikira, woyenera mapulojekiti ang'onoang'ono omwe ali ndi bajeti yochepa.
Ukadaulo wachikulire: mizere yokhazikika, kukonza kosavuta, kulephera kochepa.
Kugwira ntchito bwino nthawi yeniyeni: palibe kuchedwa kwa kutumiza mawu, khalidwe lokhazikika la kuyimba.
Zoyipa:
Ntchito imodzi: imathandizira kuyimba koyambira ndi kutsegula, ndipo singathe kuwonjezera ntchito zanzeru (monga kanema, kuwongolera kutali).
Mawaya ovuta: zingwe za mawu ndi makanema ndi zingwe zamagetsi ziyenera kuyikidwa padera, ndipo kukulitsa kapena kusintha kumakhala kovuta.
Kuletsa kusokonezedwa koipa: kukhudzidwa ndi kusokonezedwa kwa maginito (monga zida zamagetsi zamphamvu), kuchepa kwa chizindikiro cha maginito otumizira kutali n'kodziwikiratu.
Kusasinthasintha koipa: sikungathe kuphatikizidwa ndi machitidwe ena (monga kuwongolera mwayi, kuyang'anira).
Zochitika zomwe zingagwiritsidwe ntchito: zochitika zotsika mtengo monga madera akale ndi nyumba zazing'ono zokhalamo.
Dongosolo la intaneti ya digito (intercom ya IP)
Ubwino:
Ntchito zolemera: kuthandizira kanema wapamwamba kwambiri, kutsegula patali, kumasula chidziwitso, ukadaulo wamagetsi ndi ntchito zina zanzeru.
Mawaya osavuta: Amatumizidwa kudzera mu Ethernet (PoE power supply) kapena Wi-Fi, zomwe zimachepetsa mtengo wa chingwe.
Kukula kwamphamvu: kumatha kuphatikiza njira zowongolera mwayi, kuyang'anira, alamu ndi machitidwe ena, kuthandizira kuwongolera kwa APP pafoni yam'manja.
Kuletsa mwamphamvu kusokoneza: kutumiza kwa chizindikiro cha digito ndikokhazikika, koyenera madera akuluakulu kapena kutumizidwa kutali.
Zoyipa:
Mtengo wokwera: ndalama zambiri mu zida ndi zomangamanga za netiweki (maswichi, ma rauta).
Zimadalira netiweki: kukhazikika kwa netiweki kumakhudza mwachindunji magwiridwe antchito a dongosolo, ndipo bandwidth ndi chitetezo ziyenera kutsimikizika.
Kapangidwe kovuta: kukonza zolakwika pa chidziwitso chaukadaulo pa netiweki ndikofunikira, ndipo malire okonza ndi okwera.
Zochitika zoyenera: nyumba zogona zapakatikati mpaka zapamwamba, nyumba zamalonda, madera anzeru ndi zochitika zina zomwe zimafuna kuphatikizana kwa ntchito zambiri.
Dongosolo la SIP intercom (lozikidwa pa protocol ya VoIP)
Ubwino:
Kugwirizana kwakukulu: Kutengera ndi protocol ya SIP yokhazikika, imatha kulumikizidwa bwino ndi njira zolumikizirana zodziwika bwino (monga IPPBX, softphone).
Kulumikizana kwakutali: Kumathandizira mafoni akutali kudzera pa intaneti (monga kulumikiza malo osungira katundu ndi mafoni am'manja a anthu okhala m'deralo).
Kukhazikitsa kosinthasintha: Palibe zida zapadera zomwe zimafunika, ndipo netiweki ya IP yomwe ilipo imagwiritsidwa ntchito mwachindunji kuti muchepetse ndalama zolumikizira mawaya.
Kukula: Kosavuta kuphatikiza ndi ma terminal ena a SIP (monga ma video conferencing, ma call center).
Zoyipa:
Zimadalira mtundu wa netiweki: Kuchedwa kapena kusakwanira kwa bandwidth kungayambitse kusokonezeka kwa mafoni ndi makanema osawoneka bwino.
Zoopsa zachitetezo: Ma firewall, encryption ndi njira zina ziyenera kukonzedwa kuti zipewe kuukira kwa maukonde (monga kumvetsera zinthu mobisa, DoS).
Kusinthasintha kwa mtengo: Ngati chitetezo champhamvu kapena chitsimikizo cha QoS chikufunika, ndalama zotumizira zitha kukwera.
Zochitika zomwe zingagwiritsidwe ntchito: Zochitika zomwe zimafuna kuti anthu azitha kugwiritsa ntchito patali kapena kugwirizanitsa ndi makina olumikizirana amakampani (monga nyumba zamaofesi, zipatala, masukulu).
Malangizo osankha ogwiritsa ntchito:
Ndalama zochepa, ntchito zosavuta: sankhani dongosolo la analogi.
Kukula kwanzeru komanso kwamtsogolo: sankhani njira ya digito yolumikizirana ndi intaneti.
Kuwongolera kutali kapena kuphatikiza ndi dongosolo la bizinesi: sankhani dongosolo la SIP.
Pakukhazikitsa kwenikweni, malo olumikizirana, kuthekera kokonza pambuyo pokonza, ndi zosowa za ogwiritsa ntchito ziyeneranso kuganiziridwa.
