Can I use the camera on a 5GHz network?

No, the Kami Doorbell is only compatible with a 2.4GHz band network. 5GHz networks are not supported. All routers have a 2.4GHz band network available and most routers are dual-band, meaning they have both a 2.4GHz and 5GHz band network. Many routers have both bands available simultaneously, meaning that you can see two network names for your router. Check your Wi-Fi settings to see if you have 2 networks available.
