Two-way wireless video audio data transmitter-receiver used on the ground for 1-2 km

Two-way wireless video audio data transmitter-receiver used on the ground for 1-2 km is more popular, and we get a new inquiry. Recently, a client wanted us to customize a two-way wireless video and audio data transmission system for him, which is used on the construction site. The typical ground usage scenario is that both the transmitter and the receiver are on the ground. The transmission range required by the customer is 1-2 kilomita ʻe. If there are obstacles in the middle, a repeater can be added between the transmitter or receiver for video data and audio transfer. 'I he taimi tatau, in case of problems with wireless transmission, you can switch to wired transmission at any time. And there are 4-6 cameras at the transmitter position. So he chose the following one, Vcan1752, according to his requirement details, TX900-2W-15KM is recommended.

Ko e sipinga Vcan1752: ʻIkai poupouʻi ha extender

Ko e sipinga ʻoku fokotuʻu atu TX900 supports a range extender. Customers need to purchase three sets of transceivers, one as a transmitter, the other as a receiver, and the third one can be placed as a relay in places with poor signal.

The relay is like the above picture. The drone in the sky is the extender. The transmitter and receiver are on either side of the mountain. UAVs in the sky can connect the transmitter and receiver.

Fehu'i: The transceiver at the vehicle and controller are not identical. I assume You said buying 3 units meaning they are all identical.

Tali: The transceivers are actually the same as them. The transmitter, the receiver, and the extender are all the same product. They’re transceivers and can both receive and transmit data and audio.

11. Wired Transmission:

The model Vcan1752 you mentioned: NOT support

The recommended model TX900 support to added extended net cable.

The ordinary network cable supports 100 meters at most. If you use optical fiber, you need to add an optical transceiver module.

Fehu'i: Will the audio and control + feedback data go through optic fiber?

Tali: Optic fiber is like a net cable, which can connect the transmitter and receiver by cable. Audio and Video are together transmissions at the same time.

Fehu'i: If two transceivers can transmit control + feedback wirelessly, they should be able to transmit control + feedback via optical fiber. Because I need to control and see the status of my vehicle when using optic fiber.

Tali: Kataki ʻo fili ʻa e filo optic transceiver mo RS232 RS485 feʻaveʻaki ʻo e fakamatala.
