よくある質問
Q: Can your wireless video transmitter and receiver transmit data at the same time as video? What if I have additional text or control data to send— is that supported?
A: はい. Our wireless video transmitter and receiver support simultaneous video and data transmission.
The system is equipped with an RS232 data port for transmitting text or control data alongside the video signal.
If you require data transmission, please inform us when placing your order, and we will reserve and configure the RS232 data input on the metal enclosure for your device.
FAQs
- はい, the frequency range can be changed from 170Mhz (より良い from 220Mhz) 860MHzまで. So it can work well at 260Mhz band.
- The frequency should be modified to the same on the transmitter and receiver. Of cause, the Power Amplifier and antenna frequency should modify the same frequency. (You need to buy a power amplifier and antenna for the transmitter and receiver to meet your changed frequency).
- In order to improve the sensitivity of transmitting and receiving, the frequency bandwidth is generally made very narrow (中心周波数 ±15メガヘルツ, so bandwidth should be 30Mhz). The power amplifier of the transmitter and the frequency of the antenna are specially customized according to the frequency you need.
- It is best when you place an order, please tell me what kind of working frequency you need. Our engineers will modify the frequency of the transmitter and receiver, and also modify the PA and custom antenna according to this frequency range to ensure the best sensitivity and support the longest transmission distance.
- The default frequency is 590Mhz, With 30Mhz (+/-15メガヘルツ), you can change it without modifying the Power Amplifier and antenna. 例えば, 578メガヘルツ, 584メガヘルツ, 590メガヘルツ, 596メガヘルツ, and 602Mhz.
- If you need to modify the transmitter frequency and bandwidth, you need a special tool of the parameter configure board, please see the below picture, it is not a default accessory, please buy it at an extra cost or contact us before ordering.

はい, it supports to send the video and UART data 送信機と受信機から.
As it is one-way transmission, so it can not send the control command from the receiver to the transmitter.
If you need to send control commands or other data from the receiver to control other devices such as cameras or drones at the transmitter, you can add a set of cheap digital transmission equipment, お問い合わせ, and we can customize it for you.

Please check the UART define on the transmitter and receiver at the below link. Please tell me if you want to have a lead cable. (default is no)


The transmitter default Power Amplifier is 2 ワット, so it can support 30 KM at line-of-sight.
The below picture is our tested distance from the mountain to the seaside.
If you want to transmit a longer range, you can increase the power amplifier. In addition to one watt and two watts, we can also make 5 ワット, 10 ワット, そして 20 watts for your choice. Larger amplifiers also require larger batteries and current support.

For 20W PA, the power supply should be 24~28V. Only at 28 volts can the power amplifier achieve the best workability.
Our engineer can change the frequency to 300Mhz from the default 590Mhz, The antenna, and PA in the warehouse are 590Mhz, 300Mhz needs two weeks to customize, so the delivery time needs longer than our default 590Mhz.

ステップ 1: Please press OK and the right button at the same time, a menu of whether to save appears on the screen.

ステップ 2: Please press OK to choose Yes to save.

Remind, please use the bigger or longer antenna if your project allows, it can get better reception performance in the larger range.

The default full set
- SD Transmitter ( PA 0.5W, 1W, 2W, 5W, 10W, 20W, 50W optional according to your order demand)
- SD Transmitter antenna
- HDMI CVBS output receiver with parameter control menu and small screen
- 0.8-meter Receiver antenna 1 個. (There are two types of installing or fixing the antenna: 1. magnetic sucker base antenna, 2. デフォルト U-type clamp FRP fiberglass antenna )
- Optional, parameter configuration board for the wireless video transmitter.
(If you need a magnetic sucker base antenna, the express or carrier thinks the magnetic products will interfere with their plane safety, so the shipping cost is higher than a U-type clamp antenna. )
The default full set package dimension
- 84*21*12CM
- Gross Weight 4.5KG
- If you choose over 100cm antenna and magnetic sucker base antenna, Some freight forwarders will charge extra fees, such as extra long fees and extra fees for strong magnetic items.
- The transmitter parameter configures board is different from the one on the receiver. The firmware on the parameter configure board was different from the transmitter and receiver, they cannot be used interchangeably.
- The transmitter parameter configures board can adjust the signal attenuation on the transmitter. Per 0.3db will reduce the 0.5W PA.


質問: Is it possible to change the outpout power (internal PA 0,5 w, 1 w, 2 w) via the configuration board?

- As answered above, you can adjust the output power by setting the parameters of ATTEN through the parameter configuration board tool on the transmitter. (This tool does not include the default package, you need to notify that you want to have this tool when you order)
- If you buy 2W PA, then you can set it 0.5W, 1W, but can not change it to 5W.
- We also can make it to 5W, 10W, 20W, and 50W if you need to support long-range.
いいえ.
This wireless video transmitter only supports CVBS camera or video input, other type of video camera needs an extra converter box.
いいえ. It is COFDM (DVB-T) テクノロジー.
So the COFDM frequency range is 170-860Mhz. It can support 477, 610, 675, 724, 816メガヘルツ, but can not support 970, 1180, 1230 メガヘルツ.
Our special model transmitter can support all the above ranges, but the receiver needs to use the downconverter block.
In order to allow our wireless transmitting system to support a wider range and better signal strength, we generally set the operating frequency to a certain point (170~860Mhz), and its supported range is only plus or minus 15Mhz. 例えば, the center frequency is 590Mhz, max support frequency range should be 575Mhz~605Mhz, The PA and antenna are specially customized according to this center frequency.
- For COFDM video transmitter, you do not need to install additional wave pass filter.
- If your use environment is very complex, in order to improve the receiving sensitivity and reduce clutter interference, you can add additional band-pass filter to the wireless COFDM video receiver to shield the interference caused by the frequency of other devices to the received signal.
- If you need to add a dial-through filter, you can refer to the following link on our website and purchase them together. We can test them together to ensure that the two products work well and will not cause sensitivity loss.
- Frequency Bandpass Filter
