What happens when the Internet goes out?
The alarm portion of your security sensor does not rely on your business Internet and it will not be affected.
If you have video devices, they will not be able to record events without the Internet. However, if you have a stream video recorder (SVR), the cameras set to record to the SVR will continue to record as long as both units are powered and are still connected to the local Wi-Fi network (assuming the router is still functional). You won’t be able to view the footage from the SVR until the Internet is operational.
