What's the quality of Ye Wei surveillance camera network camera, and is it effective?

Tiandi Ye Wei is a big engineering brand, focusing on engineering. As far as the product is concerned, it belongs to the upper-middle level, slightly lower than Haikang Dahua, but still higher than other unknown products. At least the brand is there and the service will keep up.

However, as the project is the breakthrough point, Tiandi Ye Wei's products are mainly for personal use, and the quotation is relatively high. In order to ensure the profit of engineers, the retail price is higher than that of Haikang Dahua.
