06Frequently asked questions

Why does it alarm on a belt buckle?

Belt buckles contain metal. A tray or a lower setting solves most cases.

Can false alarms be eliminated?

They can be reduced a lot with the right setting, position and a tray.

Do you provide screening staff?

No. Qyvea supplies, installs, configures and trains. Your own staff operate it.
