Video Transmitter TX Module

1. We can adjust the RF bandwidth of this model to 2M/QPSK and increase the receiving sensitivity to -98 (actual), which is 7dB higher than the original sensitivity. This will more than double the corresponding transmission distance.
2. What UAVs care about is the size and weight of the Video Transmitter TX Module. The weight of the whole machine can be within 100g.
3. The Wireless Video Transmitter TX Module transmission itself has a delay of 75Fröken
4. One-way COFDM video transmission, mainly used for FPV(First Person View)
5. SD video transmission, RF bandwidth up to 2M, end-to-end delay of less than 120Fröken
6. Default 3W PA support 50km (DEN)
7. The default working frequency is 595 Mhz, and we can customize 170~860 Mhz
8. Videokodningsformat: H265
9. Dimensionera: Motherboard size: 50 X 35 X 10mm; overall machine size: 67 X 48 X 23mm (3W and above lower output)
10. Protection standards: All-aluminum radiator shell, anti-rust, stötsäker design
11. Detta FPV video transmission supports digital encryption (AES128 bitar). Unlike ordinary FPV analog video transmitters, it cannot be encrypted. Others can also see the same real-time video on the same frequency.

Video Receiver RX Module

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

1. The FPV1887 video transmission video delay latency is small, endast 120 millisekunder. COFDM-912T delay is more than 400ms.
2. With different modulation bandwidths, with the exact video resolution, the FPV1887 video transmission only requires 2MHz bandbredd, while COFDM-912T requires more than 6MHz.
3. 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.
4. 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.
5. 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.
6. 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.
7. More amplifiers to choose from 1 watt, 2 watt, 3 watt, och 4 watt. (default 3-watts support 50km)

FAQ

Fråga: Why does powering on the transmitter cause its shell to become very hot?

Svar: Först, we tested this circuit board at temperatures of minus 40 degrees and 85 grader. The hand feels very hot and will not affect the normal use of the transmitter.
Andra: There are two reasons why the case temperature is a bit high:

1. To be waterproof, our casing does not have heat dissipation holes and fan holes.
2. To support 50 kilometer, 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.

Fråga: The shell of this transmitter looks very heavy, and not suitable for installation on a drone that needs to be lightweight, höger?

Fråga: What is the power of the transmitter without an additional amplifier? 100-200mW?

Fråga: Why is your FPV video transmitter price higher than the UHF analog video transmitter?

Svar:

1. This FPV video transmitter is not an ordinary FM-modulated analog video transmission.
2. 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.
3. The FM-modulated video transmission frequencies are 1.2G, 1.3G, 2.4G, och 5.8 G. 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.
4. 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.

Fråga: What is the bandwidth of the channel?

Svar: 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.

Fråga: Can I combine a directional antenna with a circular?

Fråga: Is it possible to set the input and output video type manually (PAL / NTSC)?

Svar: KOMPIS / NTSC both support, auto-detect, and switch according to your input camera.

Fråga: We need a configured board for the transmitter. How much it costs?

Svar: 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, såsom frekvens, bandbredd, AES password, etc.

Fråga: Does the receiver have analog and HDMI output?

Svar: Ja, 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.

Fråga: Extra wave filters for drones – we need this (how much does it cost?)

Svar: 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.

Fråga: We need a direct RF antenna input in the FPV video transmitter metal case. Can you make it?

Fråga: Is the power of the transmitter and receiver 12 volt? What amperes?

Fråga: What are the default settings for this FPV camera transmitter and receiver? (How to reset to factory settings)
