Hello Zelalem,
Good day. Thank you for your question.
May I know if you have gone through our Wiki page - https://wiki.teltonika-gps.com/view/Teltonika_DualCam on how to connect the Dualcam and the ways to troubleshoot it.
I would suggest that you reach out to us via VIP Helpdesk or contact your Sales Manager/Distributor. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to info@teltonika.lt
Thank you for your understanding.
Kind regards.
