Good day. Thank you for your question.
There are plans to have the FMX640 devices support DualCam, tentatively by end of Q4 2022 but this is subject to confirmation. I would suggest that you reach out to our Sales Manager for the latest update. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/

Thank you for your understanding.
