Eny, ho an'ny rohy rc angon-drakitra an-tsary tsy misy tohiny roa tonta, ny teny nalaina dia eo amin'ny fototry ny vondrona iray. Raha mila mpandefa iray sy mpandray iray ianao, dia tokony ho 2X ny vidin'ny tarika.
Misy ihany koa ny mpanjifa mividy set telo na mihoatra, ny eo afovoany dia ny relay mba hanitarana ny elanelana.
Misy ihany koa ny mpanjifa manana émetteur maromaro sy resevera na émetteur iray sy resevera maromaro, ny habetsahana dia araka ny filanao, noho izany ny vidiny dia ny vidin'ny unit X quantité.

Ny haavon'ny sidina an'ity drone ity dia miankina amin'ny fampiharanao tena izy. Ny halaviran'ny fampitana noresahintsika eto dia mifototra amin'ny elanelana hita maso. NY (tsipika-maso).

Manana mpanjifa sasany izahay izay mampiasa balaonina toetr'andro eny amin'ny habakabaka (24-37km) hanaraha-maso ny fiasan'ny fitaovana sy ny fiasan'ny fitaovana..
Betsaka ihany koa ny mpanjifa mampiasa UAV, mitazona fotsiny ny UAV ambony noho ny sakana amin'ny tany.

Ao amin'ny horonan-tsarimihetsika fitsapana amin'ny tany, mba hitsapana ny halaviran'ny fifindran'ny 30 ny 150 kilaometatra, matetika dia ilaina ny mananika ny tendrombohitra avo manodidina 1,000 metatra, ka malalaka ny sahan'ny fahitana.

Ny fanamafisam-pahefana dia fanitarana famantarana ho an'ny halavirana lavitra kokoa. Izahay dia afaka mamatsy 0.3W, 1W, 2W, 5W sy 10W.
Raha jerena ny halaviran'ny fifindrana 30km-50km, aleo misafidy 2 Watts ho an'ny 30 ~ 40 km ary 5 Watts ho an'ny 50-80 km. 10 watts PA manohana 100 ~ 150km.

Eny, Ny singa tsirairay amin'ny maodely bidirectional roa tonta dia ny transceiver. Azonao atao ny mametraka ny singa rehetra ho toy ny relay na repeater eo anelanelan'ny mpanentana sy ny mpandray.

Eny, Ny singa tsirairay amin'ny TX900 dia manana ethernet RJ45 roa ho an'ny fakantsary IP. (manohana ihany koa ny fanitarana fakan-tsary bebe kokoa amin'ny alalan'ny net switch), seranana data telo, ary ampidiro-peo roa roa tonta.

Ny TX900 sy Vcan1681 dia manana fanomezan-dàlana rindrambaiko momba ny halaviran'ny fampitana. Tsy manana an'io toerana io ny Vcan1818, ny halaviran'ny fampitana dia miankina amin'ny fanamafisam-pahefana.

Eny, fanohanana

Mitovy ny kalitaon'ny horonan-tsary amin'ny 55km sy 80km.
Ny fatran'ny asa dia tokony hifidy araka ny politikan'ny fanomezan-dàlana matetika eo an-toerana.
Raha manana DVB-T ny eo an-toerana / DVB-T2 digital TV, Ny elanelana matetika dia avy amin'ny 170 ~ 860Mhz, dia 1.4Ghz no soso-kevitra.
Andramo ny misoroka ny faneriterena efa ampiasaina amin'ny faritra eo an-toerana araka izay azo atao mba hampihenana ny fitsabahana sy hialana amin'ny kalitaon'ny sary mangatsiatsiaka na mosaika..

Eny, azonao atao ny mametraka ny matetika ao amin'ny rindrambaiko Web UI na amin'ny alàlan'ny fitaovan'ny board configuration parameter.
Ny antenna sy ny fanamafisam-pahefana PA dia miasa amin'ny elanelana matetika. Ny elanelana matetika dia raikitra rehefa namboarina.
Noho izany dia tokony ovainao koa ny antenne sy PA rehefa ovainao ny fatran'ny frequence dia tsy ao anatin'ny elanelan'izy ireo.
Ohatra, rehefa miteny aminay ianao dia manaiky fa 1.4G ny frequence miasa, dia ny antenne sy PA dia hiasa tsara amin'ny 1.4G, na dia afaka manova ny mpanelanelana sy ny mpandray miasa matetika ho 800Mhz, mila manova antenne 800Mhz sy PA koa ianao.

Ny TX900 dia manana elanelana telo matetika izay mety ho safidy, 800Mhz, 1.4Ghz, sy 2.4gz.
Vcan1818 miasa isan-karazany azo preset araka ny tetikasa ilaina.

rehefa mividy izany ianao, raikitra ny fanamafisam-pahefana sy ny elanelana fifindran'ny max, 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) na 806 ~ 826MHz (800Mhz), or optional 2401.5~2481.5MHz (2.4G).
You must choose 1.4G, 800Mhz, 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.
Noho izany, ny injenieranay dia tsy manoro hevitra ny hanovanao ny matetika matetika. Raha mbola mila manao izany ianao, tokony hanova ny frequent émetteur aloha, dia ovay mitovy amin'ny émetteur ny frequence receveur.
Tsara kokoa raha averinao indray ny émetteur sy ny récepteur. Raha tsy reboot ianao, afaka miasa koa izany.

Azafady, jereo ny baiko PC AT amin'ny rohy eto ambany.

1. Ao amin'ny tarika frequence mitovy (ny 1.4g), ny tahan'ny fampitana izay resahinay matetika (antsoina koa hoe ny tahan'ny interface tsara) miankina indrindra amin'ny bandwidth tsy misy tariby (toy ny 10MHz, 20Mhz) ary ny masontsivana modulation Wireless (toy ny QPSK, QAM16, QAM64).
2. Anisan-dry zareo, ny bandwidth tsy misy tariby dia napetraky ny mpampiasa (toy ny pejy tsy misy tariby eo ambanin'ny pejy web), fa ny masontsivana fanitsiana tsy misy tariby dia automatique sy dynamically napetraky ny rafitra. Ohatra, QAM64 is used for short distances, and QAM16/QPSK is used for long distances. This is different from one-way cofdm image transmission.
3. Ohatra, 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.
As for what wireless adjustment parameters to use under what conditions, or the currently used wireless adjustment parameters, customers need to explore and operate by themselves.
4. What frequency band the customer chooses should not be based on the transmission rate of the high-frequency band, but also based on the legitimacy of the frequency band and whether the frequency band is “clean”. Theoretically, the radio wave in the high-frequency band corresponds to a short cycle, ka fohy ny fotoana fampitana ary haingana ny tahan'ny fifindrana, fa ny sanda teorika manokana, Tsy afaka mamaly anao aho, ny tena sanda, ny mpanjifa dia afaka mitsapa izany amin'ny alàlan'ny rindrambaiko fandrefesana hafainganam-pandeha (ny “fepetra” Ny pejin'ny pejin-tranonkala TX900 dia tafiditra amin'ny fandrefesana hafainganam-pandeha IPERF)

Ny rafitra misy anay dia rafitra fampitana mangarahara. Midika izany fa video na data ampidirinao, hamindra azy ireo izahay. Ahoana ny fifehezana ny robot, anjaranao izany.
Manana mpanjifa mampiasa fakantsary PTZ izahay, ny receiver koa dia manana joystick hifehy ny fakan-tsary PTZ, zoom, mihetsika na mihodina.

1. Ao amin'ny faritra hita maso, Ny halaviran'ny rafi-pitaterana an-tariby misy anay dia miankina amin'ny halaviran'ny fampitana noresahintsika sy ny fanamafisam-pahefana mifanandrify izay fidinao rehefa mividy. Afaka misafidy avy amin'ny 7km 15km, 30km, 50km 80 km, 100km, ary 150 km.

2. If the transmission module you choose can support up to 100 kilaometatra, but you do not choose our default 5-watt power amplifier, then this distance cannot be reached.

3. It is difficult to answer how many kilometers our transmission system can transmit in the case of non-line-of-sight.
Because non-line-of-sight transmission distance depends on what is the obstacle between the transmitter and receiver?
If it is a metal-enclosed box indoors or on a mountain, the transmission distance cannot be determined.
Wireless video transmission signals are just like radio or GPS signals, they must be able to obtain signals in the presence of diffraction. Preferably in an open area.

This is perfectly fine,
We also have customers who use it for long-term video surveillance in harsh situations such as borders, grasslands, mines, and reservoirs.

1. Connecting more cameras also ensures smooth video, depending on the pixels you choose for video and the transmission distance.

2. Our default transmission bandwidth is 20Mbps. If you connect four or five cameras, the pixels of each camera reach 1080p, and the transmission distance is more than 30 kilaometatra, the video will occasionally freeze. When this happens, you can adjust the video format to a lower video pixel, or reduce the number of cameras connected to the transmitter.

1. The answer to this question is basically the same as the previous one because the bandwidth rate of our single set of links is 20Mbps. Connecting more transmitters, each transmitter will occupy the corresponding bandwidth.

2. The smoothness of the video depends on the pixels and transmission distance of each camera you choose. Below is a video of us testing three transmitters and one receiver in our office. The picture is quite smooth.

1. Every transmitter and every receiver has its unique IP address. Which transmitter and camera you access from the receiver depends on whether you know the IP address you set beforehand. This ensures that, even if many sets of transmitters or receivers are in the same location, you can only access devices whose IP addresses you know.

2. At the same time our transmission and reception also support AES encryption and decryption. Even if other unauthorized users know your IP address, they cannot access or view the video of the transmitter and camera to ensure the privacy of wireless transmission.

1. Ny ankamaroan'ny mpanjifanay dia mampiasa ny mpilalao RTS amin'ny solosaina mba hijery na handrakitra ny votoatin'ny horonan-tsary amin'ny fakantsary IP.

2. Raha mila manangana NVR ianao, Ny injeniera dia afaka manome fanampiana amin'ny fametrahana araka ny fitaovanao manokana NVR.

1. Izahay sy ny injeniera dia hanome fanampiana amin'ny antsipiriany sy fanamafisana lavitra araka ny filanao.

2. Ho an'ny fampahalalana ara-teknika manokana, araka ny filanao, hotsarainay raha azo sokafana maimaimpoana. Fa ho azo antoka fa afaka mampiasa ny fitaovana ara-dalàna ianao.

Raha ampiasaina 10W power amplifier, mety hahatratra 150~200km izany. (NLOS)

Noho ny fikorianan'ny tany, izay miteraka sakana eo amin'ny mpandefa sy ny mpandray, ary mitaky halavirana lavitra, ilaina ny miantoka fa ny fiaramanidina dia manidina avo be na mampiasa fiaramanidina mission intermediate ho fampitaovana.

According to our understanding, the hottest part should be the air unit(the access node), because the environment inside the aircraft is very narrow and closed.

1. The next time you find this kind of problem, you need to use the elimination method, because in general, the probability of unilateral problems is higher. Ohatra, if we suspect that there is a problem with the access node at the aircraft unit. then we only restart the access node at the aircraft unit. Do NOT restart the central node on the ground side to see if you can connect after restarting the access node on the aircraft side, there is a high probability that there is a problem with the access node on the aircraft side.

2. If there are conditions, ohatra, if the wired network port of the access node on the aircraft is exposed, then you can connect it to the computer, and log in to the wireless link web page (toerana misy anao 192.168. 1.12). On the debug page, send any AT baiko, and check whether the wireless transmission system can respond to AT commands normally.

3. There is a link core module in our transmitter and receiver. It has a log function. Before the flight, it will always record the operation status of the wireless link. When there is a problem, return to the ground, export the log information, and send the log file to MorningCore Help to analyze the reason there. How to get Log files to analyze and resolve TX900 link interruption faults.

Our wireless video data transmission system supports AES 128 fanafenana, Banks also use this encryption algorithm. for more information, you can google search aes128.
