Ultra Violet (UV) Balancing | 紫外线（UV）平衡

UV light is always present and is particularly strong at high altitude and next to the seaside. The exposure to such high radiation reduces performance and can blind the PIR lenses. In order to combat this, the detectors have a UV filter.

紫外线始终存在，在高海拔处和海边额外强烈。暴露在如此高的辐射下会降低性能，并可能使PIR镜头失效。为了解决这个问题，探测器有一个紫外线过滤器。
