Long Range Videyo Transmetè pou dron, Ultim Gid FAQ

Wi, pou de-fason bidireksyon san fil videyo done rc lyen an, sitasyon an se sou baz yon sèl inite. Si ou bezwen yon sèl transmetè ak yon sèl reseptè, Lè sa a, pri inite a ta dwe 2X.
Genyen tou kliyan ki achte twa oswa plis ansanm, youn nan mitan se relè a pwolonje distans la pi lwen.
There are also customers with multiple transmitters and a receiver or one transmitter and multiple receivers, the quantity is according to your needs, so the cost is unit price X quantity.

The flying altitude of this drone depends on your actual application. The transmission distance we mentioned here is based on the visible range. an (line-of-sight).

We have some clients who use weather balloons in the atmosphere （24-37km）to monitor the operation and performance of the device.
There are also more customers who use UAVs, just keeping the UAV higher than the obstacle on the grounds.

In our test video on the ground, in order to test the transmission distance from 30 a 150 kilomèt, it is often necessary to climb to a high mountain of about 1,000 mèt, so that the field of vision is wide.

The power amplifier is a signal enlarger for the longer transmission distance. We can offer you 0.3W, 1W, 2W, 5W and 10W.
Considering the 30km-50km transmission distance, it is better to choose 2 watts for 30~40km and 5 watts for 50~80km. 10 watts PA support 100~150km.

Wi, every unit of the two-way bidirectional model is the transceiver. You can put any unit to as the relay or repeater between the transmitter and receiver.

Wi, each unit of TX900 has two RJ45 ethernets for the IP camera. (also support extending more cameras by net switch), three data ports, and one bidirectional audio input-output.

TX900 and Vcan1681 have software authorization on the transmission distance. Vcan1818 has no this setting, the transmission distance depends on the power amplifier.

TX900: 5 Wat: 142grams and 10 Wat 242 gram

200-300ms video (including a camera to monitor)
30-60ms data

Wi, sipò

The video quality is the same at 55km and 80km.
The working frequency should choose according to your local frequency authorization policy.
If your local has DVB-T / DVB-T2 digital tv, the frequency range is from 170~860Mhz, then 1.4Ghz is recommended.
Try to avoid the frequencies already in use in the local area as much as possible to reduce interference and avoid image quality freeze or mosaic.

Wi, you can set the frequency at the software Web UI or via the parameter configuration board tool.
The antenna and PA power amplifier are working in the some frequency range. Their frequency range is fixed when customized.
So you should also change the antenna and PA when you modify the frequency is out of their frequency range.
Pa egzanp, when you tell us you agree the working frequency is 1.4G, then the antenna and PA will be working well at the 1.4G, even if you can change the transmitter and receiver working frequency to 800Mhz, you also need to change 800Mhz antenna and PA.

TX900 has three frequency ranges that can be optional, 800megaèrts, 1.4Ghz, and 2.4Ghz.
Vcan1818 working frequency range can be preset according to your project need.

when you buy it, the power amplifier and max transmission range are fixed, and can not expend by software upgrade, except that you change the hardware of the transceiver module and PA. The assembly is complex, you’d better buy a totally new one.

Please note that our wireless transmitter module supports a frequency band. Such as 1427.9~1447.9MHz (1.4G) oswa 806 ~ 826MHz (800megaèrts), or optional 2401.5~2481.5MHz (2.4G).
You must choose 1.4G, 800megaèrts, or 2.4G when buying it. (the antenna and PA will be customized according to the frequency band).
At the frequency band, there are many frequency points. For Example, the 1.4G range is from 1427.90~1447.0Mhz. Like wifi, the module will automatically select the frequency point with the best current signal as the transmission frequency point, so you don’t need to manually modify the frequency point unless you want to change to a frequency point with the worse signal.
So our engineer doesn’t suggest that you change the frequency manually. If you still need to do it, it should change the transmitter frequency first, then change the receiver frequency to the same as the transmitter.
It is better that you reboot the transmitter and receiver. If you don’t reboot, it also can be working.

Please check the PC AT commands at the below link.

1. In the same frequency band (such as 1.4G), the transmission rate we generally refer to (also called the air interface rate) mainly depends on the wireless bandwidth (such as 10MHz, 20megaèrts) and wireless modulation parameters (tankou QPSK, QAM16, QAM64).
2. Among them, the wireless bandwidth is set by the user (such as the wireless page under the web page), but the wireless adjustment parameters are automatically and dynamically set by the system. Pa egzanp, QAM64 is used for short distances, and QAM16/QPSK is used for long distances. This is different from one-way cofdm image transmission.
3. Pa egzanp, with the same configuration of 20MHz bandwidth, the air interface rate is as high as 30Mbps at short distances, but only 3~4Mbps at extreme distances.
Kòm pou ki paramèt ajisteman san fil yo itilize nan ki kondisyon, oswa paramèt ajisteman san fil yo itilize kounye a, kliyan bezwen eksplore ak opere poukont yo.
4. Ki gwoup frekans kliyan an chwazi pa ta dwe baze sou pousantaj transmisyon nan gwoup la wo-frekans, men tou ki baze sou lejitimite nan gwoup la frekans ak si wi ou non gwoup la frekans se “pwòp”. Teyorikman, vag radyo a nan gwoup la wo-frekans koresponn ak yon sik kout, Se konsa, tan an transmisyon se kout ak to a transmisyon se vit, men valè a teyorik espesifik, Mwen pa ka reponn ou, valè aktyèl la, kliyan an ka teste li atravè lojisyèl an mezi vitès (nan “mezi” paj paj wèb TX900 la entegre ak mezi vitès IPERF)

Sipò.
Sistèm nou an se yon sistèm transmisyon transparan. Sa vle di ke videyo oswa done ou antre, nou pral transfere yo. Ki jan yo kontwole robo la, se pati ou yo.
Nou gen kliyan ki sèvi ak yon kamera PTZ, reseptè a tou gen yon joystick pou kontwole kamera PTZ la, rale, deplase oswa vire.

1. Nan seri a vizib, Ki distans sistèm transmisyon san fil nou an ka sipòte depann sou distans transmisyon nou mansyone ak anplifikatè pouvwa matche ou chwazi lè w ap achte.. Èske yo ka chwazi nan 7km 15km, 30km, 50km 80km, 100km, ak 150km.

2. Si modil transmisyon ou chwazi a ka sipòte jiska 100 kilomèt, men ou pa chwazi anplifikatè pouvwa default 5-watt nou an, Lè sa a, distans sa a pa ka rive jwenn.

3. Li difisil pou reponn konbyen kilomèt sistèm transmisyon nou an ka transmèt nan ka ki pa liy-of-sight.
Paske distans transmisyon ki pa liy-of-sight depann de ki obstak ki genyen ant transmetè a ak reseptè a?
Si se yon bwat metal ki fèmen andedan kay la oswa sou yon mòn, distans transmisyon an pa ka detèmine.
Siyal transmisyon videyo san fil yo se jis tankou siyal radyo oswa GPS, yo dwe kapab jwenn siyal nan prezans difraksyon. De preferans nan yon zòn ouvè.

Sa a se parfe amann,
Nou gen tou kliyan ki sèvi ak li pou siveyans videyo alontèm nan sitiyasyon difisil tankou fwontyè, savann, min, ak rezèvwa.

1. Konekte plis kamera asire tou videyo lis, depann sou piksèl ou chwazi pou videyo ak distans transmisyon an.

2. Pleasant transmisyon default nou an se 20Mbps. Si ou konekte kat oswa senk kamera, piksèl yo nan chak kamera rive nan 1080p, ak distans transmisyon an plis pase 30 kilomèt, videyo a pral detanzantan friz. Lè sa rive, ou ka ajiste fòma videyo a nan yon pi ba pixel videyo, oswa redwi kantite kamera ki konekte ak transmetè a.

1. Repons kesyon sa a se fondamantalman menm jan ak anvan an paske pousantaj la Pleasant nan seri sèl nou an nan lyen se 20Mbps.. Konekte plis transmetè, chak transmetè pral okipe Pleasant ki koresponn lan.

2. Lis videyo a depann de piksèl ak distans transmisyon chak kamera ou chwazi a. Anba a se yon videyo nou teste twa transmetè ak yon sèl reseptè nan biwo nou an. Foto a se byen lis.

1. Chak transmetè ak chak reseptè gen adrès IP inik li yo. Ki transmetè ak kamera ou jwenn aksè nan reseptè a depann de si ou konnen adrès IP ou fikse davans. Sa asire ke, menm si anpil seri transmetè oswa reseptè yo nan menm kote, ou ka sèlman jwenn aksè nan aparèy ki gen adrès IP ou konnen.

2. An menm tan transmisyon ak resepsyon nou an sipòte tou chifreman ak dechifre AES. Menmsi lòt itilizatè ki pa otorize konnen adrès IP ou, yo pa ka jwenn aksè oswa wè videyo transmetè a ak kamera pou asire konfidansyalite transmisyon san fil.

1. Pifò nan kliyan nou yo sèvi ak jwè RTS nan òdinatè a pou gade oswa anrejistre kontni videyo kamera IP la.

2. Si ou bezwen mete NVR, enjenyè nou yo ka bay asistans konfigirasyon dapre ekipman NVR-espesifik ou.

1. Enjenyè mwen yo ak mwen pral bay èd detaye ak konfigirasyon aleka selon bezwen pwojè ou a.

2. Pou enfòmasyon teknik espesifik, selon bezwen ou yo, nou pral jije si li ka louvri pou gratis. Men, nou pral definitivman asire ke ou ka itilize aparèy la nòmalman.

Si yo itilize 10W pouvwa anplifikatè, li ka rive nan 150 ~ 200km. (NLOS)

Paske nan koub la nan tè a, ki kreye obstak ant transmetè a ak reseptè a, epi li mande pou pi long distans, li nesesè asire ke avyon an vole ase wo oswa itilize yon avyon misyon entèmedyè kòm yon relè.

Dapre konpreyansyon nou an, pati ki pi cho a ta dwe inite lè a(ne aksè a), paske anviwònman an andedan avyon an trè etwat ak fèmen.

1. Pwochenn fwa ou jwenn kalite pwoblèm sa a, ou bezwen sèvi ak metòd eliminasyon an, paske an jeneral, pwobabilite pou pwoblèm inilateral yo pi wo. Pa egzanp, si nou sispèk ke gen yon pwoblèm ak ne aksè nan inite avyon an. Lè sa a, nou sèlman rekòmanse ne aksè nan inite avyon an. PA rekòmanse ne santral la sou bò tè a pou wè si ou ka konekte apre rekòmanse ne aksè a sou bò avyon an., gen yon gwo pwobabilite ke gen yon pwoblèm ak ne aksè nan bò avyon an.

2. Si gen kondisyon, pa egzanp, si pò rezo a filaire nan ne aksè nan avyon an ekspoze, Lè sa a, ou ka konekte li nan òdinatè a, epi konekte nan paj entènèt ki lyen san fil la (default 192.168. 1.12). Sou paj debug la, voye nenpòt AT kòmandman, epi tcheke si sistèm transmisyon san fil la ka reponn kòmand AT nòmalman.

3. Gen yon modil debaz lyen nan transmetè ak reseptè nou an. Li gen yon fonksyon boutèy demi lit. Anvan vòl la, li pral toujou anrejistre estati operasyon lyen san fil la. Lè gen yon pwoblèm, retounen nan tè a, ekspòte enfòmasyon boutèy la, epi voye dosye log la bay MorningCore Help pou analize rezon ki fè la. Ki jan yo jwenn dosye Log pou analize ak rezoud fay entèripsyon lyen TX900.

Sistèm transmisyon done videyo san fil nou an sipòte AES 128 chifreman, Bank yo itilize tou algorithm chifreman sa a. pou plis enfòmasyon, ou ka rechèch google aes128.

1. U-ki gen fòm kranpon mòn pou 120cm Reseptè antèn vèr FRP

2. 150cm Coaxial câbles pou antèn transmetè 29cm

3. 150cm Câbles kowaksyal pou antèn reseptè 120cm

Li ka ale dirèkteman nan 55km, ak wotè avyon an ta dwe plis pase 300 mèt. Li pi bon yo wè nan, san okluzyon, oswa pa gen fondamantalman oklizyon tou pre antèn la.

Konsomasyon pouvwa mwayèn nan transmetè videyo a se mwens pase 1.1A@24V, ak konsomasyon pouvwa mwayèn nan reseptè videyo a se mwens pase 0.8A@24V. Ranje ekipman pou pouvwa 24 ~ 28V.
