Affordable asset tracking

The AG51 is an affordable, GPS location tracking device designed to protect mobile assets. Whether equipment is left at public construction sites or expensive equipment is leased out, the AG51provides security and peace of mind that assets are safe and where they should be.

Detect & recover lost or stolen assets

Easy-to-use geofence alerts enable users to instantly detect and respond to theft and unauthorized use. Alerts are sent via email or SMS when assets move outside of designated areas, such as a job site or street address. Customizable ping rates allow you to configure the device to your needs.

Automatically compile inventory and dormancy reports

Gain complete visibility into the locations of your assets, and eliminate the need for manual inventory checks. The AG51 syncs with Samsara's cloud-based dashboard to provide automated inventory reporting and a visual map of all of your assets in one place.

Identify unused assets to optimize inventory pools

Quickly identify assets that are unused and dormant for long periods of time. Underutilized assets can be moved to higher demand sites or consolidated to maximize resources.

Long-lasting replaceable batteries for unpowered use

The included batteries last up to 4 years with 2 check-ins per day. This enables long-term monitoring of assets leased out or left on job sites for years at a time.

Installs in less than 5 minutes

With a weatherproof and water-resistant design (IP69K rating), the AG51 can be installed on any mobile asset in just minutes using either durable, high strength tape or anti-theft screws.
