What setting can I configure via the transmitter parameter configuration board tool?
3 sets of FPV camera transmitters with one extra transmitter parameter configuration board tool

Awọn paali meji wa, 40x30x21cm 4kgs ati 96x60x12cm 5kgs. Nitori awọn iwọn didun ti awọn meji paali ti awọn ọja jẹ jo mo tobi, ile-iṣẹ gbigbe nigbagbogbo n gba owo 12 kilo.
One set of FPV transmitters and receivers, with an 80cm receiver antenna and one parameter tool for the transmitter.
Gbigbe Fidio Alailowaya jẹ ọkan ninu awọn paati pataki ti FPV. FPV tumo si iran eniyan akọkọ. Lati mọ wiwo eniyan akọkọ ti ọkọ ofurufu naa, o jẹ dandan lati lo eto gbigbe Fidio Alailowaya lati gbe fidio laaye lati kamẹra FPV pada si awọn gilaasi / iboju ti awaoko..
Lati irisi ipo gbigbe, Ailokun fidio gbigbe ti wa ni o kun pin si meji orisi, ọkan jẹ afọwọṣe fidio gbigbe, ati awọn miiran jẹ oni fidio gbigbe.
Gbigbe fidio Analog ti ni idagbasoke fun igba pipẹ ati pe o ni awọn anfani nla ni awọn ofin ti idaduro. Idaduro jẹ kekere, nitorina o ti wa ni lilo pupọ ni ere-ije ati apẹrẹ ti n fo.
Gbigbe Fidio oni nọmba jẹ imọ-ẹrọ tuntun, pẹlu kekere lairi, ijinna gbigbe to gun, ati ki o clearer images pẹlu HD o ga.
Eto gbigbe fidio alailowaya ti pin si awọn ẹya meji: opin gbigba ati opin gbigbe.
Ipari gbigbe jẹ kamẹra ati atagba fidio ti a fi sori ọkọ ofurufu naa. Kamẹra ṣe iyipada aworan ti o ya sinu afọwọṣe tabi ifihan agbara oni-nọmba ati gbejade si atagba fidio alailowaya, ati atagba atagba ifihan kamẹra nipasẹ redio.
Ipari gbigba jẹ iduro fun gbigba ati fifihan ifihan loju iboju.
We had a distance of 3 at first, and then after the settings, we were able to improve the video to 10 km, but then the picture disappeared again. A fi eriali ni inaro si oke ati gbe sinu iru ọkọ ofurufu naa, aworan dara si, sugbon a ko fò siwaju ju 20 km sibẹsibẹ. Ati pe ipinnu wa ni 40 km tabi diẹ ẹ sii.
Ṣe o ni awọn aworan eyikeyi ti awọn paramita lori olugba lakoko ọkọ ofurufu ati awọn aworan fifi sori ẹrọ ti gbigbe fidio UAV?
Mo nilo lati mọ giga ti eriali ati giga ti n fo ti drone lati pinnu kini o tumọ si lati lo lati pọ si ijinna ti n fo..
Mo nifẹ si gbigbe fidio fun drone fpv kan, CVBS ni 30+ km, Mo tun nilo telemetry redio ni ijinna kanna. Ṣe o ṣee ṣe lati so olugba pọ si awọn gilaasi Skyzone?
A ni atagba fpv ati olugba, awọn olugba ni o ni HDMI ati CVBS o wu si awọn atẹle. O le sopọ pẹlu atẹle awọn gilaasi ti o ba nilo rẹ.
