We are constantly away on business, or travel away at the weekend, and it is just at these times that you do not have any control over your property. Of course, we had alarm systems, but nobody heard them, and if someone heard them, then it was too late. But now we have a real sense of security!
If a stranger is detected on our grounds, I immediately receive a message via an app, that is really practical! The security centres then uses a loudspeaker to tell the intruder to leave the property. Intruders are then frightened off!
