The role of the video display stand in teaching is becoming more and more obvious.So how should we choose this product? Let us discuss it together.
Demonstration effect should be the first consideration when purchasing a visualizer, because the demonstration effect directly affects the quality of the demonstration. Price is also very important, and products with good cost performance will be the first choice for users. In terms of booth functions, users need to choose the functions that suit them according to their use occasions, habits, and upgrade development.
This gooseneck video booth is a new upgrade from the traditional booth. It has a built-in 5 million camera, 1080P high-definition display, supports 10x optical zoom and 10x digital zoom. When zooming in and out, there is almost zero delay and no smear. The picture quality is clear and smooth.
The document camera best buy is also important for the performance of pictures or text. However, some poor quality display products have greatly improved the black and white contrast in order to make up for the lack of the display booth’s ability to express text. The result is that the document camera sacrifices the grayscale and color performance. In the actual purchasing process, the visualizer’s ability to express text and the ability to restore pictures with rich colors can be compared separately.
The imaging of the lens of Qomo gooseneck video visualizer has good uniformity. Whether it is telephoto or near, the focus of the center of the lens is basically the same as the focus of the edge, and there is basically no obvious difference. It adopts A3 large format design and large intake area, which can completely display all the content/format of the textbook.
Of course, after-sales service should also be an important purchasing factor that users value very much. The overall quality of Qomo’s gooseneck visuzlier is good, providing customers with one-to-one after-sales service.
