Yes, it’s possible! GuardHome make it possible for you to set your alarm from anywhere in the world.
I recently took a three week trip to Colombia and had no problems checking on my home even from 5000 miles away. All I needed was internet connectivity to access a simple app on my smart device.
Not only was I able to set my alarm, I was also able to check on all the perimeters of my home and see who had come in and out of the house.
This technology is available for the majority of our security systems subject to inspection.
