RF Wireless Video Receiver Dimension 70×80×15mm
Here is the FPV video transmitter with a metal case.
Why this model is better than COFDM-912T as an FPV video transmitter?
The difference between COFDM-912T and FPV1887 wireless video transmission is
- The FPV1887 video transmission video delay latency is small, එකම 120 මිලි තත්පර. COFDM-912T delay is more than 400ms.
- With different modulation bandwidths, with the exact video resolution, the FPV1887 video transmission only requires 2MHz කලාප පළලක්, while COFDM-912T requires more than 6MHz.
- FPV1887 has a longer-range transmission distance, stronger diffraction performance, and anti-interference performance. Because it uses a narrower bandwidth, it has higher receiving sensitivity and takes up fewer resources.
- Smaller size and weight: Compared with COFDM-912T video transmission, the FPV-1887 video transmission adopts a more advanced encoding and modulation scheme, with lower overall power consumption, smaller size, and a weight of only 80g.
- The unique 45-degree RF antenna design is more suitable for the FPV and is more suitable for the high-speed flight angle of the FPV.
- The video transmission of this FVP1887 is suitable for vehicles with a flying speed of about 120km. For vehicles with higher flying speeds, the video delay will appear larger and the control will not be so good.
- More amplifiers to choose from 1 වොට්, 2 වොට්, 3 වොට්, සහ 4 වොට්. (default 3-watts support 50km)

ප්රශ්නය: Why does powering on the transmitter cause its shell to become very hot?
පිළිතුර: පළමුවන, we tested this circuit board at temperatures of minus 40 degrees and 85 උපාධි. The hand feels very hot and will not affect the normal use of the transmitter.
Second: There are two reasons why the case temperature is a bit high:
- To be waterproof, our casing does not have heat dissipation holes and fan holes.
- To support 50 කිලෝමීටර, we have a built-in three-watt amplifier. A power amplifier requires a cooling fan. The chip and board of the power amplifier are close to the metal casing to transfer heat.
ප්රශ්නය: The shell of this transmitter looks very heavy, and not suitable for installation on a drone that needs to be lightweight, අයිතිය?
- For this product, we mainly provide transmitter boards and receiver boards or modules. Users can customize the case or install it on their own device or aircraft.
- This optional case is convenient for customers who need it to take samples for testing. There is a case to protect the circuit board from damage during transportation and testing.
- We also use lightweight and cheap aluminum, which is processed by a CNC milling machine. The shell’s protrusion is not just for looks; it improves the transmitter’s performance by dissipating heat more effectively.
- 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 උපාධි, it will automatically protect itself and the video will be frozen.
ප්රශ්නය: What is the Camera resolution? HDMI සඳහා සහය දක්වයි?
ප්රශ්නය: What is the power of the transmitter without an additional amplifier? 100-200mW?
ප්රශ්නය: Why is your FPV video transmitter price higher than the UHF analog video transmitter?
පිළිතුර:
- This FPV video transmitter is not an ordinary FM-modulated analog video transmission.
- Ours is COFDM digital video transmission, not the FM-modulated analog video transmission you understand. Video Quality is SD720P, clearer, stable. It is more resistant to interference and supports video encryption.
- The FM-modulated video transmission frequencies are 1.2G, 1.3ජී, 2.4ජී, සහ 5.8 ජී. The biggest advantage of video transmission is that it is cheap. The transmission distance is limited to short distances with an eye-see line of sight.
- Our FPV video transmitter can transmit HD video at ultra-low altitudes and non-line-of-sight conditions. A specialized receiver is required to decode it.
ප්රශ්නය: Can we assemble the repeater by ourselves using two sets of receivers and transmitters?
පිළිතුර: ෂුවර්, 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, සම්ප්රේෂකය, පුනරාවර්තකය, 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. කරුණාකර පහත පින්තූරය පරීක්ෂා කරන්න. We have put the receiver and transmitter in one box.
There are two frequencies, උදාහරණයක් වශයෙන්, 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 ග්රෑම්, 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.
ප්රශ්නය: What is the idea of using two of the same antennas on the receiver?
පිළිතුර: 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.
ප්රශ්නය: What is the bandwidth of the channel?
පිළිතුර: The default is 6Mb. You also can change it from 2MB, 4මෙබ, 6මෙබ, 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.
ප්රශ්නය: Can I combine a directional antenna with a circular?
ප්රශ්නය: Is it possible to set the input and output video type manually (PAL / NTSC)?
පිළිතුර: PAL / NTSC both support, auto-detect, and switch according to your input camera.
ප්රශ්නය: We need a configured board for the transmitter. How much it costs?
පිළිතුර: 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, කලාප පළලක්, AES password, ආදිය.
ප්රශ්නය: Does the receiver have analog and HDMI output?
පිළිතුර: ඔව්, 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.
ප්රශ්නය: Extra wave filters for drones – we need this (how much does it cost?)
පිළිතුර: 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.
ප්රශ්නය: 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.
ප්රශ්නය: Is the power of the transmitter and receiver 12 volts? What amperes?
ප්රශ්නය: What are the default settings for this FPV camera transmitter and receiver? (How to reset to factory settings)
ප්රශ්නය: Why do transmitters and receivers need to support encryption and decryption functions?
What you should tell us when you order?
