Hello, We are looking 4G Camera that works with this service, all we have found it haven´t FTP support, which reference/brand does you support or are tested ?

There are few such camera models. We have not reviewed any of them. However, you might be able to work around by:

(1) Check if any such cameras can email image snapshots or video clips. CameraFTP supports both FTP and SMTP.

(2) Use a 4G/LTE mobile access point (wireless router) + one or more regular IP cameras. This solution is more flexible and costs less. You can have multiple IP cameras share one mobile access point.
