ឧបករណ៍បញ្ជូនវីដេអូ Quad ជាមួយឧបករណ៍បញ្ជូនអូឌីយ៉ូទិន្នន័យសម្រាប់មនុស្សយន្ត ឬរថយន្តដែលដំណើរការពីចម្ងាយ Mini FPV

សំណួរគេសួរញឹកញាប់:

សំនួរ: What’s the operating distance achieved in LOS and NLOS?

សំនួរ: What is the delay of your Ground Robotic Vehicle system?

ចម្លើយ: Video and Audio at 150~300 milliseconds. (including the camera and display monitor). Data latency at 40 មិល្លីវិនាទី.

សំនួរ: Do you have an AV with bidirectional data transmission?

ចម្លើយ: Do you mean unidirectional video transmission and bidirectional data transmission? This model supports one-way video transmission, two-way audio, and data transmission. The transmitter supports the installation of four cameras, microphones, loudspeakers, and lidar data collection; the receiver has HDMI and RJ45 ethernet outputs to the computer, as well as MIPI and LVD outputs.

សំនួរ: Can you make it smaller?

ចម្លើយ: បាទ. We can make it smaller and change the 4-watt PA power amplifier to 2-watt PA. Two BNC Audio Input Output will change the smaller IO connector. នេះ New Transmitter dimension is 13*10*3.7cm.

សំនួរ: Why is the video quality very good when the camera is fixed, but when it is shaken in the hand, the video becomes blurry?

ចម្លើយ: This is caused by video image compression. In order to pursue the real-time nature of the video image, the amount of data compressed by the image will increase when it shakes. The transmitter’s software will improve the video image quality to ensure low latency.

សំនួរ: What is the user ID and password when I want to use the Advanced setting?

ចម្លើយ: Admin, 123456

More FAQ

1. How to set the minimum value of the retransmission number.

សំនួរ: Is there a way in the video/Audio/Data module to change its retransmission to a minimum value so that it should not retransmit the previous data if the RF range breaks? បច្ចុប្បន្ន, there is no option available for retransmission control to minimum value.

ចម្លើយ: The number of retransmissions can be set and configured on the web page.

The transmitter and receiver both have an ethernet port. Please connect it to your PC via net cable. Type default IP 192.168.1.20 in the browser and enter the web management page.
The default user is admin និង password is 123456

Three here means that the number of retransmissions is three. You can also change it to 0.

What is set on the transmitter is the number of retransmissions from the transmitter to the receiver, and what is set on the receiver is the number of retransmissions from the receiver to the transmitter.

2. What is the password for the software of RX and TX?

The below password is used for the web page where the customer logs in, and there is an advanced setting in the serial port software.

3. Does your ground robot transmitter support 1080P 30X zoom camera？

Our ground robot transmitter supports connecting PTZ cameras.

Because our transmitter video input only supports AHD and CVBS camera input, not common IP cameras, there is no problem with your AHD 30X ZOOM camera.

Common PTZ cameras require RS485 protocol to connect the joystick and camera. Our transmitter and receiver default support RS232, so you must purchase an RS232⇄RS485 adapter board.

Something you need to confirm when order

1. ច្រកទិន្នន័យ, RS232 (លំនាំដើម) ឬ RS485?
2. Video Transfer Frequency: Default is 430-440Mhz.
3. Length of the Transmitter and Receiver Antenna.
4. អ្នកទទួល: Do you need a normal box without a screen and control panel or need a handheld remote control panel? (ស្ថានីយ៍ត្រួតពិនិត្យដី)

Do you know? The closer the wireless transmission antenna is to the ground, ចម្ងាយបញ្ជូនកាន់តែខ្លី.

Today, a customer visited our factory to test our equipment’s performance, transmission distance, and anti-interference ability. As per his requirement, the transmitter and antenna are 30cm from the ground, and the receiver and antenna are 80cm from the ground.

The wireless transmission system used for ground robot vehicles or remote-controlled cars needs to solve three problems.

1. Send the video from the transmitter’s four cameras to the receiver. The operator of the receiver can select any one video of the four-way channels, or combine the four videos on one display.
2. Through the built-in two-way transceiver data transmission system, the operating instructions for controlling the transmitter sent from the receiver can be transmitted to the transmitter. ក្នុង​ពេល​ដំណាលគ្នា, the real-time position of the transmitter and the data collected by the detection sensor are transmitted to the receiver.
3. Through the built-in two-way audio voice system, you can have two-way voice calls communication, or you can use the microphone and speaker installed on the transmitter to board cast from the receiver to the transmitter or monitor the transmitter’s sound.
