Uma unemibuzo mayelana nemikhiqizo yethu noma uhlu lwamanani, sicela usishiyele i-imeyili yakho futhi sizoxhumana nathi zingakapheli amahora angama-24.
BUZANI MANJE
Imininingwane
| Imikhiqizo ekhethekile ye-intercom yokwakha ifoni emnyango wevidiyo (isekela zonke izinhlobo ze-IP Video door phone building intercom) |
| 24V (imodi yokunikezwa kwamandla: 45+, 78-) |
| iswishi yokucwilisa ukuze ukhethe ukudluliselwa okungu-100m noma okungu-250m |
| indlu enembobo yokufakelwa odongeni, ukufakwa okulula. |
| Ithiphu efudumele: qaphela ukuhleleka kwezixhumi zekhebula lenethiwekhi yokunikezwa kwamandla - imodi eqondile; (i-upstream 1 gigabit optical port ongayikhetha, i-standard control sharpener) |
| nomsebenzi wokunikezwa kwamandla okuvikela |
Umdwebo Wesakhiwo
Imibuzo Evame Ukubuzwa
Umbuzo 1. Iyini injongo yesistimu ye-IP yokwakha ividiyo ye-intercom yomnyango we-doorbell?
A: Uhlelo lwe-IP building video intercom doorbell lwaklanyelwe ukuhlinzeka ngokuxhumana okuphephile nokulula kanye nokulawula ukufinyelela kwezakhiwo ezinamayunithi amaningi. Luvumela izakhamuzi ukuthi zixhumane nezivakashi emnyango, zizibuke ngevidiyo, futhi zinikeze ukufinyelela kude uma kudingeka.
Umbuzo 2. Iyini i-Non-standard POE switch kanye nendima yayo ohlelweni?
A: Iswishi ye-POE engeyona ejwayelekile iyiswishi ye-Power over Ethernet eyenzelwe ngqo uhlelo lwe-IP building video intercom. Ihlinzeka kokubili idatha kanye namandla kumamonitha angaphakathi nakwamanye amadivayisi axhunyiwe, okwenza kube lula inqubo yokufaka ngokudinga uxhumano olulodwa lwekhebula le-CAT6/CAT6 kwiyunithi ngayinye.
Umbuzo 3. Kubaluleke ngani ukucushwa kwezibuko ezahlukene (4+2, 8+2, 16+2, 24+2) kumaswishi e-Non-standard POE?
A: Ukucushwa kwezibuko ezahlukene kuvumelana nenani lama-monitor angaphakathi angaxhunywa ku-switch. Isibonelo, i-switch engu-8+2 inganika amandla futhi iphathe ama-monitor angaphakathi afinyelela kwangu-8, kanye nokuhlinzeka ngezinketho zokuxhumana ze-uplink ngokusebenzisa ama-port amabili engeziwe.
Umbuzo 4. Iyini injongo ye-"Dip switch" kulezi switch?
A: I-"Dip switch" ihlose ukukhetha ibanga lokudlulisela lamadivayisi axhunyiwe. Ingashintshwa ukuze ikhethe phakathi kwebanga lokudlulisela elingamamitha ayi-100 noma angama-250, kuye ngezidingo ezithile zokufakwa.
Umbuzo 5. Ungachaza ugesi owakhelwe ngaphakathi kanye nokubaluleka kwawo?
A: Ugesi owakhelwe ngaphakathi unikeza amandla kagesi adingekayo kokubili inkinobho ngokwayo kanye namamonitha angaphakathi axhunyiwe. Kuqeda isidingo semithombo yamandla eyengeziwe futhi kuqinisekisa inqubo yokufaka elula, okwenza kube lula ukusethwa nokugcinwa kwesistimu.
Umbuzo 6. Uhlelo lusekela kanjani ukuxhumana ngaphakathi kweyunithi?
A: Amaswishi afaka phakathi ama-uplink network ports akhuthaza ukuxhumana ngaphakathi kweyunithi. La ma-ports avumela ukuxhumana okungenamthungo phakathi kwamadivayisi ahlukene ngaphakathi kweyunithi efanayo yokwakha, okufaka isandla ohlelweni lokuxhumana oluhlanganisiwe nolusebenzayo.
Umbuzo 7. Ziyini ubukhulu nesisindo salezi zishintshi ze-POE ezingezona ezejwayelekile?
A: Ubukhulu kanye nesisindo kuyahlukahluka ngokusekelwe ekucushweni kwembobo. Ubukhulu busukela ku-202*140*45mm kuya ku-310*182*45mm, kanti isisindo esiphelele sisukela cishe ku-1.1kg kuya ku-2.2kg, okuqinisekisa umklamo omncane futhi osebenzisa isikhala kahle wezidingo ezahlukene zokufakwa.
Umbuzo 8. Ingabe iswishi ye-POE engeyona ejwayelekile ingalungiselelwa izilungiselelo ezahlukene zokufaka?
A: Yebo, amanye amamodeli anikeza ukucushwa okukhethwa kukho njengokubekwa kudeskithophu noma ukuhlonyiswa ngezindlebe zokufaka ikhabethe. Lokhu kuguquguquka kuhambisana nezintandokazi ezahlukene zokufakwa futhi kuqinisekisa ukuhambisana nezimo ezahlukene.
Umbuzo 9. Ungachaza isikhathi sewaranti salezi zishintshi.
A: Zonke izinkinobho ze-POE ezingezona ezejwayelekile ziza nesikhathi sewaranti sonyaka owodwa. Lesi siqinisekiso simboza amaphutha okukhiqiza futhi siqinisekisa ukuthi izinkinobho zisebenza ngokuthembekile kuyo yonke impilo yazo ehlosiwe.
Umbuzo 10. Iyini injongo yamachweba kagesi e-Gigabit cascade kanye nechweba le-SFP kumamodeli eswishi amakhulu?
