Teltonika DualCam - Video saved as 0 Filesize

I have a Teltonika DualCam configured to work with a Teltonika FMC125 device.
I am receiving images without any issues, regardless of the picture resolution but,
if I configure the video settings to send a recording of "3 seconds before and after trigger" the video is saved with 0 as the Filesize.

If I for example, then configure the video settings to send a recording of "1 second before trigger" it is saved correctly including a Filesize of approximately 237KB.

Is anyone aware of a setting on the Teltonika device or Traccar server I need to change to make it work for larger videos?

There's no server side configuration needed.

Thanks for clarifying Anton,

If someone is making use of Teltonika Dualcam devices please confirm you are receiving videos of 3 to 5 seconds before and after trigger.
I have tried multiple different settings and configuration without success.
See current config that works with 1 second before trigger

I can't get Video either only images. I changed the setting to only send video and there are some data getting in logs but i can't get any on event or media folder.Any luck?

Are you using the latest version?
