The Magician
A colleague (in a previous life) attached a small light to his alarm system. The light - visible externally if you knew where to look - was turned on when the alarm was triggered, and could only be turned of by manually resetting the alarm.
When returning home he would look at the state of the light. If it was on he would phone the security company & arrange for them to check the property before he entered.
I get an instant email and push bullet notification on both my and the wife's phones if the alarm is triggered. So I then already have the alarm company go check it out. I get this notification before they even call me.
The email function also have failover. If the internet is down, there is still a ctwug link which as an email server which is used as backup. The ctwug connection actually have 2 links out from my property so there is redundancy there too.
