In many of our videos you will see a simplisafe alarm. We purchased that system thinking we could self-monitor, but simplisafe can only be remotely monitored, controlled, etc if you have their monitoring service. Alarm system monitoring is not possible when one moves every week or two, due to regulations around integration into the 911 system, etc. So, we couldn't actually arm it when leaving the RV. Sure, it would alarm, but there would be no way for us to be notified, no one to shut if off, and Daisy would go insane. We didn't know this when we bought it, so it was essentially just an expensive door chime for over a year
We've since switched to Ring for our security system and have a full article and video on that here.
