You’ve got questions? We’ve got answers

When I get notified that my alarm has been triggered, how do I find out if it was an actual emergency or a false alarm?

You will need to contact your local police department. However, if the triggered alarm signifies an actual emergency, in most cases the authorities will notify the central monitoring station, which will then contact you.

Can I move my equipment myself?

No. If you need equipment moved, contact customer support. They will either walk you through the process or send a certified technician to assist you.

Why did I get charged a false alarm fee?

Some cities do charge a fee for sending dispatch for a false alarm. If you feel there has been a mistake, you can contact customer support and they will be happy to discuss it with you.

Where are your monitoring stations located?

We have two monitoring stations: one in St. Paul, Minnesota, and one in Provo, Utah. Additionally, all of our customer support representatives are located in the United States. We do not contract with off-shore providers.

Do you monitor 24x7x365?

Yes. We have monitoring staff available at all times, including nights, holidays, and weekends. We also have customer support agents available 24x7x365.

How quickly does Vivint respond in an emergency?

We respond to most emergency calls in fewer than 10 seconds.

Will the installation damage my walls?

Technicians drill only two holes through the entire installation process: one to link the touchscreen panel to your home’s power grid and one in your door frame if you choose to install recessed door sensors. These holes are unobtrusive and cannot be seen once the products are installed. Other sensors and detectors are installed using a couple of screws, similar to hanging a picture on your wall.
