Yes, Nanit does work with both 2.4GHz and 5GHz WiFi networks. However, there's a small caveat. The original Nanit camera primarily uses the 2.4GHz band for better performance. Pairing your phone with your 2.4 GHz network before starting the setup process is recommended. On the other hand, the newer models of Nanit cameras, including the Nanit Plus and Nanit Pro, support both 2.4GHz and 5GHz WiFi.Depending on your home network configuration, this dual-band WiFi capability provides more flexibility and better connection quality.
