COFDM Wireless Downlink Receiver
The COFDM Diversity Receiver is compact digital diversity receiver with integrated H.264 or H.265 decoding in a compact and lightweight housing, suitable for use in fluid and high-mobility applications. The unit accepts signals from two antennas to significantly enhance the demodulated performance and increase the operating range. The receiver can find and lock automatically to the incoming transmission quickly according to the pre-set frequency and bandwidth. This receiver features a range of comprehensive signal outputs including HD at 720p and 1080P, down-converted HD CVBS monitor video, and two analog audios is supported.
The receiver also includes DVR record functionality with Micro SD card or USB disk using REC switch controls. When paired with the COFDM wireless Downlink camera transmitter, the receiver offers a comprehensive, rapidly-deployable video and audio solution that enables advanced situational awareness. It can play an essential role in delivering real-time live video from both ground and airborne mobile platforms.

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.
