How Does Vivint Car Guard Work?

Car Guard’s hardware is a small device that you plug into your car’s diagnostics OBD-II port. This port is usually located under the driver’s side dashboard, but your vehicle’s user manual can tell you where to find it.

The Car Guard has a built-in 3-axis accelerometer that detects motion from break-ins, tows and bumps. It also contains a GPS radio to track your car’s location and a cellular radio for data communication with the Vivint Smart Home app.

And if you have Vivint’s smart home security equipment and home automation devices, you can monitor your home and car all in one app. You can find other key features below.

Car Guard isn’t cheap, but if you can swing it, we think it’s worth the cost for the wide variety of security, diagnostic and location tracking features. It’s worth noting that Vivint’s apps get overall excellent customer reviews (many smart home apps don’t).
