Does this COFDM wireless video transmitter and receiver have AES 256 or 128 encryption? the output format is full hd?

Yes, COFDM-912T supports AES 128 encryption. Please notify us to plus a Parameter Configuration board for setting the AES128 password when you are placing the order. It is optional to buy. The COFDM-912T transmitter only supports SD720P Video input. So even if the receiver has HDMI output, it cannot output real 1080P high-definition video, only 720P. If you have very high requirements on the definition of picture output, I suggest you choose a model that both the transmitter and receiver support 1080P, COFDM-908T

How to assemble the wireless video transmitter, camera, and battery?

Please check the below picture. There are two power connectors at the transmitter, the red connector is 12V output for the camera, and the black connector is 12V input.

What is the lag or delay in milliseconds of your COFDM-912T?

200-300ms with a regular camera and monitor. Normal camera and screen have a delay of 200 milliseconds, right? With our 100 milliseconds, it's about 300 to 400. We also have one with 30 milliseconds, but the price is 6 times that 300 milliseconds is acceptable if your plane has an automatic obstacle avoidance function.

I noted your transmitter can support up to 30 kilometers in LOS. How far will it support in the NLOS environment?

It's hard to say the range of non-line-of-sight use, it depends on how many obstacles are in the middle. It is difficult to transmit if fully surrounded metal or mountains block it. The test environment is unique, and the distance obtained from the test is also different. We can't make any guarantees or promises about this.

We are a company that offers a solution to some rural areas here in the Philippines to monitor their rivers. If we purchased a 2W(30km) in the NLOS location, it could be reduced to 20km or more?

It is hard to say, it should depend on the obstacles between the transmitter and receiver. We don't test it in your use environment, So I can't tell you. The same product will be interfered with differently in different environments, and the transmission distance is hard to say. Only the actual test will know. Buyer: Actually, we have installed a radio transceiver that gathers a data sensor and transmits its data to an 18km distance center command. The operation is smooth and ok. The same place we're going to put up the device that we will buy from you. As you have said, only an actual test will answer all of my questions.

Can the COFDM-912T TX device output separate serial data?

Data can only be transmitted in one direction from the transmitter to the receiver. If you need to transmit data in both directions, you need to add a digital radio telemetry. (wireless data transceiver) .

I would like to know if the transmitter can also output serial data on what the camera is capturing. Other than RF does it have a separate rs232 output for the transmitter?

Yes, COFDM-912T supports transferring the serial data for you. Please check the below picture.

In this module where I can put up the camera? What type of camera is suited for this device?

The black one on the left shows a little bit of the above picture, which is connected to the camera. It supports a 720p CVBS composite AV camera. or any HDMI camera by HDMI to AV converter box.

Q: Hi, I am looking for a long-range hd video transmitter with hdmi input and a receiver with hdmi output.

Would you like a one-way or two-way system? As long as you need to send the video, do you still need to send the control operation of the drone?

Q: Only transmit and receive in a surveillance center. The idea is to use the HDMI output of the remote control and retransmit it to the central. The drone has a system to transmit over the internet, but there is no internet in the desert, so we need to retransmit but not with the internet.

OK, our one-way long-range wireless video transmission solution is the base of COFDM technology (similar to DVB-T digital TV broadcasting). It is not on the base of the Internet.

Q: Can it reach 30 km around?

In the introduction of the wireless video transmission system, all the transmission distances mentioned are based on the visible range (LOS). The 2WPA power amplifier supports 30 kilometers and is usually used on drones. The altitude is very high and the receiver is on the ground, so there is an obvious height difference between the transmitter and the receiver, and the wireless signal is transmitted in accordance with the waveform. The signal loss is small and other interference is very little clutter. You mentioned that your usage scenario is that both the transmitter and receiver are on the ground, especially in desert areas, and there may be rolling sand dunes. Therefore, the signal transmitted wirelessly is easily interfered with. So here are the suggestions: 1. Try to use a high-power transmitter, such as 10 Watts or 20 Watts. Many of our ship customers use 20W transmitters. 2. Try to use a higher antenna or put the antenna on the roof or a nearby hill, and you can also increase the antenna tripod. Our clients always choose some 1.8-meter FRP omnidirectional fiberglass antenna s. 3. If conditions permit, a repeater can also be added to enhance the signal strength and increase the transmission distance. The repeater can be fixed at a high place or on the roof of a moving car.

Ọganihu kachasị ọhụrụ na COFDM (Usoro ọnụọgụ ọnụọgụ ọnụọgụ nke Orthogonal) wireless video transmitter and receiver technology have transformed how video is transmitted and received. COFDM is a modulation technique that allows digital data to be transmitted over a wide range of frequencies, resulting in a more reliable signal and improved data transmission.

We use COFDM technology in numerous applications, such as digital television, ikuku vidiyo nnyefe, na digital radio. It’s also found in military and aerospace applications like satellite communications and unmanned aerial vehicles.

N'ikpeazụ, recent advancements in COFDM wireless video transmitter and receiver technology have transformed the way video is transmitted and received. This technology has enabled high-definition video transmission over wireless networks, as well as video transmission over a variety of networks and devices. The use of advanced coding techniques, such as forward error correction (FEC) and adaptive modulation, has enabled this.
