Yes, the Alarm (Gen 2) Starter Security Kit also works without an internet connection. The base station has an integrated battery back-up system that keeps it running for up to 24 hours if the power supply fails. You can control the system at any time via the keypad and it remains armed even in the event of a power failure.

For your main purpose - the audible alarm if you are at home and someone breaks in at night - the system works perfectly without the internet. The siren is triggered when sensors detect a break-in, regardless of whether there is an internet connection. You will be able to hear the alarm clearly.

Without the internet, however, you will not receive any app notifications on your smartphone. Control is then only possible via the keypad. If you want optional remote notifications later, Ring offers a mobile phone backup system with an integrated SIM card that becomes active in the event of an internet failure - however, this requires a paid Ring Home subscription.
