Ii-FAQ malunga ne-Wireless Video Transmitter kunye ne-Receiver
Abathumeli bethu bevidiyo abangenazingcingo banazo ezi ntlobo zonxibelelwano lwevidiyo: I-HDMI 1080P kunye ne-4K HDMI, CVBS indibaniselwano, SDI, AHD, IP Ethernet, BNC, okanye usixelele uhlobo olufunayo, injineli yethu iya kulungisa ukuhlangabezana neemfuno zakho.
Umgama wethu wothumelo unokuhlengahlengiswa ngokongeza ii-amplifiers zamandla. Ngoku, ezona ziphambili zezo 15km, 30km, 50km, 80km, 100km , kunye ne-150km, exhomekeke kwiimfuno zabathengi.
Kunjalo, imigama yothumelo edweliswe ngasentla yonke ingaphakathi LOS umgca wokubona uluhlu. Ukuba kukho imiqobo phakathi komthumeli kunye nomamkeli, NLOS (ukungaboni kakuhle), umgama wothumelo uncitshiswe kakhulu, kuphela 1km okanye 2km, kuxhomekeke kwinani lemiqobo ephakathi kunye nemekobume yendawo engenazingcingo.
Indlela enye kuthetha, Sinokusasaza kuphela kwaye sikhuphele ividiyo okanye idatha ukusuka kwi-wireless video transmitter ukuya kumamkeli kwicala elinye, kwaye asikwazi ukulayisha ividiyo okanye idatha evela kumamkeli ukuya kumthumeli. Olu hlobo lukwabizwa ngokuba yi-simplex.
Indlela-mbini ithetha ukuba, Asikuphela nje sinokukhuphela ividiyo okanye idatha kwi-transmitter yethu engenazingcingo ukuya kumamkeli, kodwa kwakhona sinokulayisha ividiyo okanye idatha evela kumamkeli ukuya kumthumeli. Oku kulungele kakhulu ukusebenza kweedrones. Awunakubona kuphela ividiyo yexesha lokwenyani ethunyelwa kwidrone, kodwa layisha kwakhona umyalelo wokulawula i-drone okanye umyalelo wokulawula ikhamera ye-PTZ ukulungelelanisa i-angle kwi-transmitter.. Oku kungasebenza ngaxeshanye. Olu hlobo lukwabizwa ngokuba yi-half-dulpex okanye i-full-duplex.

Uninzi lwee-Wireless video transmitters ngoku ziyaxhasa AES128 okanye AES256 bit encryption kunye noguqulelo oluntsonkothileyo, kuxhomekeke kwimodeli oyikhethayo. Nceda uqhagamshelane nathi ukuze uqinisekise.
Iifrikhwensi zazo zombini isidluliseli sevidiyo esingenazingcingo kunye nesamkeli sevidiyo esingenazingcingo inokuguqulwa. Abasebenzisi kufuneka bathenge iibhodi zokucwangcisa ezongezelelweyo parameter.
kunjalo, Ukuqwalasela ukuba i-amplifier yamandla ehambelanayo kunye ne-eriyali sele ilungisiwe ngaphakathi kuluhlu oluthile xa iimpahla zithunyelwa ngaphandle.. Ukuba umsebenzisi ulungelelanisa ukuphindaphinda kwe-transmitter, ehambelanayo iamplifier yamandla, I-eriyali yothumelo kunye ne-eriyali yomamkeli kufuneka kwakhona iguqulwe ibe ngamaza afanayo, kwaye aba basebenzisi kufuneka balungiselelwe. Ukuba akukho njalo, iya kubangela ukuba ukuphindaphindwa kwevidiyo engenazingcingo yahluke kwi-eriyali rhoqo, ukwenza ulwamkelo lubenzima. Ke nceda uqiniseke ukuba wazisa amaxesha achanekileyo owufunayo ngaphambi kokuba wenze iodolo.
Ukuba yeyokhuseleko okanye imfihlo, unga sebenzisa ufihlo kunye noguqulelo oluntsonkothileyo imisebenzi yesidlulisi kunye nomamkeli, enokuqinisekisa ukuba ukuhanjiswa kwevidiyo yakho kubucala. .
Ewe, yonke imveliso yethu iiparameters zinokulungiswa ngokweemfuno zomthengi. Ukuba unesicelo esikhethekileyo, nceda usazise ngekhonkco elingezantsi.
