Use passive FTP on Bosch FlexiDome DN IP Camera

Hi!

Do someone know if it is possible to use passive (PASV) FTP for JPEG posting instead of active on Bosch FlexiDome DN IP Camera?

Only found following settings under JPEG Posting:

- JPEG Format

- File Name

- JPEG Posting Interval

- FTP Server IP Address

- FTP Server Login

- FTP Server Password

- Path On FTP Server

Is it maybe possible to write some script in the "Alarm Task Manager" so it uses the PASV command instead?

Have 4 of those cameras and they all have firmware 305 00 410 (1.13)

Thanks in advance!
