Hei ass de FPV Video Sender mat engem Metal Fall.
Firwat dëse Modell besser ass wéi COFDM-912T als FPV Video Sender?
Den Ënnerscheed tëscht COFDM-912T an FPV1887 drahtlose Videoiwwerdroung ass
- D'FPV1887 Video Iwwerdroung Video Verzögerung Latenz ass kleng, nëmmen 120 Millisekonnen. COFDM-912T Verzögerung ass méi wéi 400ms.
- Mat verschiddene Modulatiounsbandbreedungen, mat der exakter Videoopléisung, der FPV1887 Video Transmissioun verlaangt nëmmen 2zréckkomm bandwidth, iwwerdeems COFDM-912T verlaangt méi wéi 6MHz.
- FPV1887 huet eng méi laang Streck Transmissioun Distanz, méi staark Diffraktiounsleistung, an Anti-Interferenz Leeschtung. Well et eng méi schmuel Bandbreed benotzt, et huet méi héich Empfangsempfindlechkeet a hëlt manner Ressourcen op.
- Méi kleng Gréisst a Gewiicht: Verglach mat COFDM-912T Video Transmissioun, der FPV-1887 Video Transmissioun adoptéiert eng méi fortgeschratt Kodéierung a Modulatioun Schema, mat engem nidderegen allgemenge Stroumverbrauch, méi kleng Gréisst, an a Gewiicht vun nëmmen 80g.
- Den eenzegaartegen 45-Grad RF Antenne Design ass méi gëeegent fir de FPV an ass méi gëeegent fir den Héichgeschwindeg Fluchwinkel vum FPV.
- D'Videoiwwerdroung vun dësem FVP1887 ass gëeegent fir Gefierer mat enger Fluchgeschwindegkeet vun ongeféier 120km. Fir Gefierer mat héijer Fluchgeschwindegkeet, de Video Verspéidung wäert méi grouss schéngen an d'Kontroll wäert net sou gutt sinn.
- Méi Verstärker fir ze wielen 1 Watts, 2 Watts, 3 Watts, an 4 Watts. (Standard 3-Watt Ënnerstëtzung 50km)
FAQ
Fro: Firwat mécht d'Kraaft vum Sender datt seng Schuel ganz waarm gëtt?
Äntwert: Éischten, mir getest dëser Circuit Verwaltungsrot bei Temperaturen vun Minus 40 Grad an 85 Grad. D'Hand fillt sech ganz waarm a wäert den normale Gebrauch vum Sender net beaflossen.
Zweeten: Et ginn zwee Grënn firwat de Fall Temperatur e bëssen héich ass:
- To be waterproof, eis casing huet keng Hëtzt dissipation Lächer a Fan Lächer.
- To support 50 Kilometer, mir hunn eng gebaut-an dräi-Watt amplifier. E Kraaftverstärker erfuerdert e Kühlfan. Den Chip a Bord vum Kraaftverstärker sinn no beim Metallgehäuse fir Hëtzt ze transferéieren.
Fro: D'Schuel vun dësem Sender gesäit ganz schwéier aus, an net gëeegent fir Installatioun op enger Dron déi liicht muss sinn, riets?
- Fir dëst Produkt, mir bidden haaptsächlech Senderbrett an Empfängerbrett oder Moduler. D'Benotzer kënnen de Fall personaliséieren oder op hirem eegenen Apparat oder Fliger installéieren.
- Dësen fakultativ Fall ass bequem fir Clienten déi et brauchen fir Proben ze testen fir ze testen. Et gëtt e Fall fir de Circuit Board vu Schued beim Transport an Testen ze schützen.
- Mir benotzen och liicht a bëlleg Aluminium, déi vun enger CNC milling Maschinn veraarbecht gëtt. D'Auswierkunge vun der Schuel ass net nëmme fir Ausgesi; et verbessert d'Performance vum Sender andeems d'Hëtzt méi effektiv opléist.
- Please mount the transmitter on the metal of the aircraft. With the addition of heat dissipation glue, it can effectively dissipate heat with the help of the metal shell.
- You can also use the four-roto of the UAV to cool its shell, which is equivalent to an external fan.
- If the transmitter board temperature exceeds 100 Grad, it will automatically protect itself and the video will be frozen.
Fro: Wat ass d'Kamera Resolutioun? Ënnerstëtzt HDMI?
Fro: Wat ass d'Kraaft vum Sender ouni zousätzlech Verstärker? 100-200MW?
Fro: Firwat ass Äre FPV Video Sender Präis méi héich wéi den UHF Analog Video Sender?
Äntwert:
- Dëse FPV Video Sender ass net eng gewéinlech FM-moduléiert Analog Video Iwwerdroung.
- Eis ass COFDM digital Videoiwwerdroung, net déi FM-moduléiert analog Videoiwwerdroung déi Dir versteet. Videoqualitéit ass SD720P, méi kloer, stabil. Et ass méi resistent géint Interferenz an ënnerstëtzt Video Verschlësselung.
- D'FM-moduléiert Videoiwwerdroungsfrequenzen sinn 1.2G, 1.3G, 2.4G, an 5.8 G. De gréisste Virdeel vun der Videoiwwerdroung ass datt et bëlleg ass. D'Transmissiounsdistanz ass limitéiert op kuerz Distanzen mat enger Aen-Siichtlinn.
- Eise FPV Video Sender kann HD Video op ultra-niddereg Héichten an net-Linn-of-Sight Konditiounen iwwerdroen. E spezialiséierten Empfänger ass erfuerderlech fir et ze dekodéieren.
Fro: Can we assemble the repeater by ourselves using two sets of receivers and transmitters?
Äntwert: Sécher, you can do like that.
If you need a relay and also control the plane, we recommend that you choose TX900, which just uses three units that can be formed a complete networking, Sender, Repeater, and receiver.
If you just need a one-way transmission system to download the video from the UAV to the repeater or ground. We recommend using our FPV repeater devices. Kuckt w.e.g. d'Bild hei drënner. We have put the receiver and transmitter in one box.
There are two frequencies, zum Beispill, 800Mhz from the transmitter to the repeater, and 300Mhz from the repeater to the receiver
To avoid interference, you also add two filters, and PA in the repeater module to increase the signal strength.
The above picture is from our engineer, he has a real sample now. The two filters and repeater are not in one box, if you confirm the order, we will do another casing or do casing by yourself according to your uav.
Relay or named repeater, which is a Kit for video re-transmission to extend the range.
The repeater with two filters is almost 450 Gramm, not including the antenna.
If the relay has two filters, is it still necessary to add a filter for the transmitter and receiver?
It is better to add a narrowband bandpass filter so that the reception performance will be very good.
Fro: What is the idea of using two of the same antennas on the receiver?
Äntwert: There are two diversity antennae on the receiver. One is ok, two is better, to get more signal from the transmitter, and increase the reception performance.
Fro: What is the bandwidth of the channel?
Äntwert: The default is 6Mb. You also can change it from 2MB, 4MB, 6MB, or 8MB if you want and buy the extra parameter tool board for the transmitter. It is better that you test at our default setting.
Fro: Can I combine a directional antenna with a circular?
Fro: Is it possible to set the input and output video type manually (PAL / NTSC)?
Äntwert: PAL / NTSC both support, auto-detect, and switch according to your input camera.
Fro: We need a configured board for the transmitter. How much it costs?
Äntwert: To reduce the transmitter’s gross weight, the configure tool of the transmitter is external. If you don’t have it, the system is also working well at our default setting. If you have it, you can change the parameters of the transmitter, such as frequency, bandwidth, AES password, etc.
Fro: Does the receiver have analog and HDMI output?
Äntwert: Jo, the receiver has both analog (CVBS, composite video output) and HDMI video output.
In order to lower the video latency, the default setting, HDMI is only a video signal, no audio signal.
Fro: Extra wave filters for drones – we need this (how much does it cost?)
Äntwert: The FPV transmitter inside already has a low pass filter inside for the drone. Please tell us what requirements do you need.
Frequency Filters have two types, one is a low-pass filter, such as the working frequency is 595Mhz, then over 610Mhz can not be passed. Another filter type is bandwidth pass filter, such 580~610Mhz can be passed, others can not be passed.
Fro: We need a direct RF antenna input in the FPV video transmitter metal case. Can you make it?
Now We designed the 45-degree tilt angle to be convenient for the transmitter antenna facing the receiver to increase the reception performance.
Fro: Is the power of the transmitter and receiver 12 volts? What amperes?
Fro: What are the default settings for this FPV camera transmitter and receiver? (How to reset to factory settings)
Fro: Why do transmitters and receivers need to support encryption and decryption functions?
What you should tell us when you order?

FAQs
Äntwert:
The default frequency is 595Mhz, (the center working frequency of the power amplifier and antenna is 595Mhz, ) I checked that this is not the range of your table mentioned. An der Zukunft, the anti-drone jammer may cover 595Mhz, we also can preset different frequencies chosen from 170-860Mhz.
