Izithutha zethu zevidiyo ezingenazintambo zinalezi zinhlobo zezixhumanisi zokufakwayo kwevidiyo: I-HDMI 1080P ne-4K HDMI, Inhlanganisela ye-CVBS, SDI, I-AHD, IP Ethernet, BNC, noma usitshele ukuthi udinga luphi uhlobo, unjiniyela wethu uzolungisa ukuze ahlangabezane nesidingo sakho.
Ibanga lethu lokudlulisela lingalungiswa ngokungeza izikhulisamandla. Okwamanje, okuyizona eziyinhloko 15km, 30km, 50km, 80km, 100km , futhi 150km, okuncike ezidingweni zamakhasimende.
Kunjalo, amabanga okudlulisela abalwe ngenhla wonke angaphakathi LOS ububanzi bomugqa wokubona. Uma kukhona izithiyo phakathi komthumeli nomamukeli, NLOS (okungewona umugqa wokubona), ibanga lokudlulisela liyancipha kakhulu, 1km noma 2km kuphela, kuye ngenani lezithiyo ezimaphakathi nendawo yendawo engenazintambo.
Indlela eyodwa kusho, Singadlulisela futhi sidawunilode ividiyo noma idatha kusuka kusihambisi sevidiyo esingenantambo siye kumamukeli ngendlela eyodwa, futhi asikwazi ukulayisha ividiyo noma idatha esuka kumamukeli iye kumthumeli. Lolu hlobo lubizwa nangokuthi i-simplex.
Izindlela ezimbili kusho lokho, hhayi kuphela ukuthi singadawuniloda ividiyo noma idatha kusuka kusidlulisi esingenantambo siye kumamukeli, kodwa futhi singalayisha ividiyo noma idatha kusuka kumamukeli kuye kusidlulisi. Lokhu kulungele kakhulu ukusebenzisa ama-drones. Awukwazi ukubona kuphela ividiyo yesikhathi sangempela edluliselwa kusuka ku-drone, kodwa futhi layisha umyalo wokulawula i-drone noma umyalo wokulawula ikhamera ye-PTZ ukuze ulungise i-engeli kusidluliseli.. Lokhu kungasebenza kanyekanye. Lolu hlobo luphinde lwaqanjwa ngokuthi i-half-dulpex noma i-full-duplex.

Ama-transmitter amaningi wevidiyo angenantambo manje ayasekela I-AES128 noma i-AES256 bit encryption kanye nokuqaqwa, kuye ngokuthi iyiphi imodeli oyikhethayo. Sicela usithinte ukuze uqinisekise.
Amafrikhwensi akho kokubili isidlulisi sevidiyo esingenantambo kanye nesamukeli sevidiyo esingenantambo kungashintshwa. Abasebenzisi badinga ukuthenga amabhodi okumisa amapharamitha engeziwe.
Nokho, uma kucatshangelwa ukuthi isikhulisi samandla esihambisanayo kanye nothiyo sekuvele kulungisiwe phakathi kwebanga elithile lapho izimpahla zithunyelwa.. Uma umsebenzisi elungisa imvamisa yesithumeli, okuhambisanayo i-amplifier yamandla, I-antenna ehambisayo kanye ne-receiver antenna kufanele futhi kulungiswe kufrikhwensi efanayo, futhi laba basebenzisi badinga ukulungiswa. Uma kungenjalo, kuzokwenza ukuthi imvamisa yesidlulisi sevidiyo esingenantambo sihluke kumafrikhwensi wothi, ukwenza ukwamukela kube nzima. Ngakho-ke sicela uqiniseke ukuthi wazisa imvamisa efanele oyidingayo ngaphambi kokufaka i-oda.
Uma kungokokuphepha noma ukugcinwa kuyimfihlo, ungakwazi sebenzisa i-encryption kanye ne-decryption imisebenzi ye-transmitter nomamukeli, okungaqinisekisa ukuthi ukudluliswa kwevidiyo yakho kuyimfihlo. .
Yebo, wonke umkhiqizo wethu amapharamitha kungenziwa egcizelele ngokwezidingo zekhasimende. Uma unesicelo esikhethekile, sicela usazise ngesixhumanisi esingezansi.

Kunjalo, siyaqonda futhi ukuthi ama-transmitters adlulisa amavidiyo angenantambo kanye nabamukeli kubiza kakhulu. Ukude nemboni yaseChina. futhi ngithemba ukuthi izimpahla ozitholayo zikufanele ukusebenza kahle kakhulu.
Uma unaka ngokukhethekile ipharamitha ethile noma umsebenzi, singathatha amavidiyo athile okuhlola ngokusekelwe kuzici ofuna ukuzibona, sicela ukhululeke ukuxhumana nathi. Ngeke ithunyelwe kuwe ngqo ngaphandle kwemvume yakho.
Ukuhlola ukubambezeleka kwesidlulisi sevidiyo esingenantambo nomamukeli, sidinga ukwenza izivivinyo ezimbili.
Okokuqala ukuhlola ukubambezeleka ukusuka kukhamera kuya kusibonisi.
Eyesibili ikhamera, kanye nesibonisi kanye nesidlulisi sesithombe esingenantambo kanye nokubambezeleka komamukeli.
Ukukhipha imiphumela yokuhlolwa emibili ukubambezeleka kwangempela kwesidlulisi sevidiyo esingenantambo nomamukeli.
Njengomhlinzeki wevidiyo ochwepheshe webanga elide le-HDMI kanye nomamukeli nomkhiqizi e-China Shenzhen, sikhiqiza i-wireless video transmitter engcono kakhulu nomamukeli iminyaka eminingi, futhi sinedumela elihle nezibuyekezo ezinhle kakhulu.
Ezinye izinhlobo ezidumile zama-wireless video transmitters, njengeBlackmagic, I-Holyland Mars 300 400s, I-Accoon cine eye 5g, I-RavenEye, Zhiyun, Inkee benbox, actiontec, I-CVW SWIFT 800, dahua, iogear, I-Artek pat-225k, i-microlite, gwinya, teradec.
Ibhajethi ehamba phambili yokusakaza ividiyo engenantambo kanye nomamukeli banezinhlelo zokusebenza eziningi, nge 4K tv, Ikhamera yokuphepha ye-CCTV, ikhamera yokusekelayo yemoto, Ikhithi yekhamera yevidiyo ye-PTZ, amandla ebhethri, ikhompuyutha, ikhamera ye-sony, uhlelo lwenkomfa yevidiyo ye-wifi, I-CanON DSLR, I-drone ye-UAV, pc ikhompyutha ephathekayo, umshini wokudlala, yemoto, I-iPhone iPad, ukusakaza bukhoma, Ikhamera yezemidlalo ye-GoPro, amajikijolo pi, Xbox.
Ividiyo ye-HD ephelele, alalelwayo, isixhumanisi sedatha esincane kunazo zonke i-1080P yevidiyo engenantambo futhi umamukeli unezixhumi eziningi zokufaka nezikhiphayo, njenge-AV eyinhlanganisela ye-CVBS, HDMI, SDI, BNC, VGA, USB.
Imvamisa ye-TX RX yomthumeli wevidiyo engenantambo ine-170-806Mhz, 1.2ghz, 2.4G, 5.8G, Ukubambezeleka okuphansi kodwa hhayi ku-zero. Ukuze usekele amabanga amade, i-amplifier yamandla ine-10w, 20Watts, futhi ngisho 30W.
Isiphi isidluliseli sevidiyo esingenantambo se-FHD esingcono kakhulu ngentengo eshibhile? Kufanele icabangele imfuneko yemininingwane yakho, khetha ngokufanele, akubizi, uma unokungabaza, Ngiyacela gcwalisa i cela i-quote ifomu, unjiniyela wethu uzokunikeza isixazululo.
