Ukusebenza
Video latency: about 200ms, when Sihid COFDM transmitter is paired with the receiver, the video(1080p60) latency from its inputting of the transmitter to the HDMI screen displaying of the receiver is about 200~250ms.
Wireless transmission range: this is relative with many conditions, the following data is just for your reference. When 1W(Amandla e-RF) COFDM transmitter paired with the receiver, 6MHz komkhawulokudonsa, centre frequency 590MHz, 5 dBi omni antenna with 2 metres to the groud on both sides, the LOS(line of sight) transmission range is about 1km to 2km. When 1W(Amandla e-RF) COFDM transmitter paired with the receiver, 6MHz komkhawulokudonsa, centre frequency 590MHz, 1.5 dBi omni antenna on the UAV(flying height 100 metre), two 7 dBi omni antenna with about 2 metre to the ground, the LOS(line of sight) transmission range is about 10km to 20 km.

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.
Sicela uhlole imininingwane kulesi sixhumanisi esingezansi. https://ivcan.com/request-a-quote-of-wireless-video-transmission/#simplex
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.
