5. Parameter Modification:

The basic parameter page is displayed by default, If users need to view or modify advanced parameters, they can short press the “UP” or “DOWN” button to switch to the advanced parameter page.

In the default mode, only the parameters can be previewed. If the user needs to modify the parameters, please long-press the “MENU” button to enter the parameter editing mode.

In the edit mode, the edited parameter value will flash and prompt, if the customer needs to switch the parameter, long-press the “UP” or “DOWN” button to switch. If you don’t need to switch parameters, you can short press the “MENU” button to switch the high and low bits of the parameter to be edited, the corresponding edited bit will flash and prompt, and then press “UP” or “DOWN” button to increase or decrease the value of the corresponding bit of the parameter.

After modifying the parameters (allowing to change multiple parameters at once), Long-press the “MENU” button, and the current parameters will all flash ( parameter name and parameter value flash together), then release the “MENU” button to complete the editing and exit the editing mode, The new parameter value will be written into the COFDM transceiver module.

6. Input and switch the most used frequency points

At Default mode, press and hold the “UP” and “DOWN“ two buttons for 2-3 seconds, then enter the most used frequency point input page (Allow to set 4 most used frequency points):

COFDM TX/RX V xx
1: Frequency (kHz)
2: Frequency (kHz)
3: Frequency (kHz)
4: Frequency (kHz)

If you have not entered common frequency points before, then all common frequency points will be displayed as 000000 (representing Not set); if common frequency points have been set before, the value of the corresponding frequency point will be displayed.

In the most used frequency point input page, the edited frequency point parameter will flash and prompt if the customer needs to switch the frequency point, long press the “UP” or “DOWN” button to switch. If you do not need to switch the frequency point, you can short press the “MENU” button to switch the high and low digits of the frequency point parameter that needs to be edited, the edited digit will flash and prompt, and then press “UP” or “DOWN” button to increase or decrease the digit of the parameter (If you want to cancel a frequency point, change the parameter of the frequency point to 000000).

After modifying the frequency parameters (Allowing to modify of multiple parameters at one time), Long-press the “MENU” button, and all current parameters will flash ( parameter name and parameter value flash together), then release the “MENU” button to complete the editing and exit the most used frequency point input page, return to the basic parameter page, and the new frequency point parameter value will be recorded in the configuration panel.

7. Switch the most used frequency point

At default mode, long-press the “UP” or “DOWN” button, and it will switch the pre-set entered the most used frequency points. (allowed to switch at up to 4 most used frequency points ), and the current switch will be displayed on the screen To the frequency point (displayed in the center and in large font), and return to the basic parameter page after staying for 5 seconds:

FAQs about Wireless Video Transmitter and Receiver

Our wireless video transmitters have these types of video input interfaces: HDMI 1080P and 4K HDMI, CVBS composite, SDI, AHD, IP Ethernet, BNC, or tell us what type do you need, our engineer will modify to meet your demand.

Our transmission distance can be adjusted by adding power amplifiers. At present, the main ones are 15km, 30km, 50km, 80km, 100km , and 150km, which depend on the needs of customers.

Of course, the transmission distances listed above are all within LOS the line-of-sight range. If there are obstacles between the transmitter and the receiver, NLOS (the non-line-of-sight), the transmission distance is greatly reduced, only 1km or 2km, depending on the number of intermediate obstacles and the local wireless environment.

One-way means, We can only transmit and download video or data from the wireless video transmitter to the receiver in one direction, and we cannot upload video or data from the receiver to the transmitter. This type is also called simplex.

Two-way means that, not only we can download video or data from our wireless transmitter to the receiver, but also we can upload the video or data from the receiver to the transmitter. This is very suitable for operating drones. You can not only see the real-time video transmitted from the drone, but also upload the command to control the drone or the command to control the PTZ camera to adjust the angle to the transmitter. This can operate simultaneously. This type also named half-dulpex or full-duplex.

Please check the details at the below link. https://ivcan.com/request-a-quote-of-wireless-video-transmission/#simplex

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, depending on which model you choose. Please contact us to verify.

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Users need to purchase additional parameter configuration boards.

However, considering that the corresponding power amplifier and antenna are already fixed within a certain range when the goods are sent out. If the user adjusts the frequency of the transmitter, the corresponding power amplifier, transmitter antenna and receiver antenna should also be modified to the same frequency, and these users need to be prepared. If not, it will cause the frequency of the wireless video transmitter to be different from the frequency of the antenna, making reception difficult. So please be sure to inform the correct frequency you need before placing an order.

If it is for security or confidentiality, you can use the encryption and decryption functions of the transmitter and receiver, which can ensure that your video transmission is private. .

Yes, all our product parameters can be customized according to customer's needs. If you have a special request, please let us know via the link below.

  1. Change the place of the receiver to avoid potential local interference from strong magnetic environments.
  2. Ensure that the antennas on both the transmitter and receiver are vertical.
  3. Please raise the antennas of the transmitter and receiver to maintain a certain height difference.
  4. Please look around to ensure that there are no obstacles between the transmitter and receiver.
  5. Change the orientation of the receiver antenna.
  6. If it doesn't work, try moving the receiver to be near the transmitter's position to see if it exceeds the effective wireless transmission distance.
  7. Or consider adding a relay of the transmitting between the transmitter and receiver.
  8. The antenna should be as high off the ground as possible, as the ground will absorb the transmitted signal.
We can, of course, supply wireless video transmitter modules and power amplifiers.
For the first sample test, I recommend that you purchase the entire set of products because our engineers have optimized the parameters to achieve the best performance.
After you have completed your test verification, you can remove the case or heat sink, install it in your device, and constantly adjust the parameters to achieve the best performance. In the future, you will be able to purchase only the modules or accessories that you require.

Of course, we also understand that wireless video transmission transmitters and receivers are very expensive. You are far away from the China factory. and hope that the goods you receive are fit for the best performance.

If you pay special attention to a specific parameter or function, we can take some test videos based on the features you want to see, please feel free to contact us. It won't be shipped to you directly without your approval.
