中国香港采购需求：LED 墙板、户外广告、广告牌、LED 显示屏、LED 屏幕面板、LED 视频面板

I'm currently in the market for an outdoor LED screen that matches the performance and quality of a specific high-resolution model. My primary need is for a product with a higher IP rating to ensure durability and weather resistance. It would be great if you could provide detailed specifications on pixel pitch, brightness levels, and overall technical capabilities of the available options. Additionally, I'm interested in understanding the installation process better. If you could share your recommendations for fixing methods, mounting options, and any required accessories, that would be very helpful. Looking forward to your expert advice on suitable products that meet these criteria.
