常見問題
This model is our lowest latency for the drone wireless video transmitter and receiver.
It supports the lowest 28-millisecond latency. (Not including the camera and monitor display time)
四氟乙烯-912T, CVBS RCA 720P Video Input, 200~400 millisecond.
COFDM-908T型: HDMI输入, 200~300 millisecond.
VCAN1729系列: HDMI输入, 20~40 millisecond. suitable for drone.
的 1729 model is ultra-low latency, which is very suitable for drones. It can detect obstacles in time, such as houses, trees, wires, 等, and avoid them in the shortest time. Many drone factories in China have adopted this video transceiver system.
- Please note that this transmitter only supports HDMI 1080P or 720P input, it does not support HDMI1080i or 720i input.
- In order to decrease the latency delay, the HDMI is not including the Audio signal. Please tell me if you need it, We will make a special firmware for your order, but the latency delay will be longer than HDMI only have video signal.
- Please also note that for the HDMI used by the drone camera, please use extremely thin and anti-interference HDMI cables. Ordinary household HDMI or cheap HDMI cables may cause unexpected failures.

What's the distinction between 1080p and 1080i?The two display systems (1080p同1080i) can both display 1920x1080 pixel images, although they do so in different ways. The letters "我" 同 "P" refer to the manner in which the images are displayed. 1080i stands for "interlaced scan" and 1080p is for "progressive scan."
How to connect Vcan1729, HDMI Wireless Video Transmitter and Receiver
- Please connect the antenna first before you power on the transmitter and receiver, otherwise the Power Amplifier inside is easy to be burned.
- The parameter configuration board tool does not need to connect when you are testing.
- The power supply of the transmitter and receiver is better to use 12V 3A.
- There is two long receiver antennae and one short antenna for the transmitter. Although you do not need our transmitter antenna, please ensure that the transmitter antenna covers the frequency of 595Mhz. 595Mhz is the center working frequency.
- In the package, there is one HDMI. It is high-quality HDMI cable for drone or robot use.
- On the receiver, there are two switches on the side. (at the first time to test, please don’t move the switch and no need connect the UART cable to other devices)
PC-LCD: UART cable operate from the computer or LCD on the receiver, there is one LCD menu. If you put the CTRL switch on the LCD side, then the receiver parameter can be adjustable by menu, if you put the CTRL switch on the PC side, then the receiver parameter can be adjustable by computer, you need connect the UART cable to the computer.
LCD power: 掣 / 喺, it can power on or off the small screen on the receiver, after change the receiver parameter, maybe you want to power off the screen displayer to save the power
- For testing, just connect the two receiver antenna on the RF1 and RF2, HDMI output to your HDMI monitor and give it power at 12V
- For testing, just connect the one transmitter on the RF, HDMI cable to connect to your HDMI camera, and give it power at 12V.
- Please contact us if you have any question, or show us the picture or video to us, we will offer you any further information.
