1·They can also radiate far infrared ray (FIR) energy of varying frequencies, which is something ordinary people can not do.
它们还可以辐射远红外线不同频率(区)的能源，这点是一般人做不到的。
2·The device utilizes an infrared ray induction system, which detects the presence of hands.
该装置利用了红外线感应系统，可以探测到双手的存在。
3·High quality light: no heat and radiation since there is no ultraviolet ray and infrared ray for the spectrum. It belongs to typical green lighting source.
光线质量高：由于光谱中没有紫外线和红外线，故没有热量，没有辐射，属于典型的绿色照明光源。
4·The discovery of infrared ray is a big jump of mankind's development.
红外线的发现是人类对自然认识的一次飞跃。
5·Sensitive technology: body heat releasing infrared ray testing technology is applied, with advantages of high sensitivity, strong anti-jamming capability and small power consumption.
感应技术：采用人体热释红外线检测技术。具有灵敏度高、抗干扰强、待机功耗小等优点。
