armband device for prisoners

Good afternoon, I would like to know if anyone knows of any device for prisoners type bracelet of those that are worn on the ankle that is compatible with traccar

I know that GoSafe had a device for that purposes:

https://gosafesystem.com/product/g737/

It should be compatible.

Probably there are other options as well.

Somebody knows the price for the G737 ?
