Firmware the latest. Internet connection is stable.

I have 2 cameras connected to the same home network. 1 of them has been showing offline for the last 3 days.

I won't be home for another month and want to make sure there is no intruder coming in, if it hasn't already.

1) What causes this offline camera issue? Just 1 camera out of 2?

2) What are the troubleshoot steps to get this camera back online while I cannot physically be home to reset the camera?
