Through wall video transmission technology is a technology that transmits videos through wireless signals, which can transmit videos captured by cameras to another room or building. This technology has wide applications in security monitoring, rescue operations, industrial testing, and other fields.
The working principle of through wall video transmission technology mainly includes three steps: signal transmission, signal processing, and video display.
Firstly, signal transmission is the core of through wall video transmission technology. It transmits the videos captured by the camera to the receiving end through wireless signals. Traditional wireless signals are subject to attenuation and interference when passing through walls, resulting in a decrease in signal quality. To solve this problem, the through wall video transmission technology adopts some special signal transmission techniques. For example, using high-frequency signals can reduce signal attenuation, and using multi antenna technology can enhance signal transmission capability. In addition, the reflection and refraction of signals can be utilized to bypass walls and achieve signal transmission through walls.
Secondly, signal processing is the key to wall through video transmission technology. The receiving end needs to process the received signal and extract video information. Due to the interference caused by signals passing through walls, the received signal may have noise and distortion. In order to improve the quality of the video, it is necessary to denoise and compensate the signal. Denoising can be achieved through filtering algorithms, and compensation can be achieved through signal reconstruction algorithms. In addition, video processing algorithms can also be used to enhance and repair videos, improving their clarity and details.
Finally, video display is the ultimate goal of wall through video transmission technology. The receiving end needs to convert the processed signal into an video and display it on the screen. video display can be achieved through a monitor or projector. In order to improve the display effect of videos, high-resolution display devices and optimized video display algorithms can be used. In addition, virtual reality technology can also be used to display videos in a virtual environment, achieving an immersive viewing experience.
Overall, through wall video transmission technology achieves video transmission between walls through wireless signal transmission. Its working principle includes three steps: signal transmission, signal processing, and video display. By using special signal transmission techniques, signal processing algorithms, and video display devices, high-quality video transmission and display can be achieved. With the continuous progress of technology, the application scenarios of through wall video transmission technology will continue to expand and deepen, bringing more convenience and innovation to people's lives and work.
