When the distance to the router is the same, the 5GHz signal is weaker than the 2.4GHz signal, which is determined by the physical characteristics of electromagnetic waves: the longer the wavelength, the less attenuation, and it is easier to bypass obstacles and continue to propagate. The 5GHz signal has a high frequency and short wavelength, while the 2.4GHz signal has a low frequency and long wavelength. Therefore, the 5GHz signal has a greater attenuation when passing through obstacles, and its ability to penetrate walls is weaker than that of the 2.4GHz signal. In view of this, the camera only supports 2.4GHz Wi-Fi.
