Trailers have no power of their own, get lent between crews, and are the easiest thing in the yard to steal. A solar tracker on each one shows where it is today and tells you when it moves.
Trailers are shared, left on job sites, and parked at a foreman's house. Finding one means phone calls.
A trailer can be hitched and gone in a minute, and the theft is often noticed days later.
Most trailers have no battery of their own, and a tracker wired to the lights only works while it is hitched.
The FC-101S-PRO mounts with screws, magnets, or straps. It charges from daylight, so there is no wiring and no battery to change.
On the Locate plan the trailer checks in once a day. On the $11.99 plan it reports when it starts and stops moving.
When the trailer is parked in a shop or under a roof, the tracker scans Wi-Fi access points to place it.
Set a geofence around the yard or a job site in iMatrix Cloud and get told when the trailer crosses it.

No. The FC-101S-PRO charges from its own solar panel and mounts with screws, magnets, or straps. Nothing connects to the trailer wiring.
The FC-101S-PRO scans nearby Wi-Fi access points to estimate its position when satellites are out of view. For trailers kept under cover most of the time, the battery-powered FC-115 is a better fit because it does not depend on sunlight.
On the $11.99 plan the tracker reports when the trailer starts moving and when it leaves a geofence you set, so you can see the movement as it happens.
The FC-101S-PRO is $125 per trailer, plus a plan from $7.99 per month. There is no contract and you own the hardware.
Yes. Trailers, vehicles, and equipment appear on the same iMatrix Cloud map under one login.
