Thanks Philippe,
Important Keyword in your case is “FTP Upload”!
FTP Upload was mainly made for typical Web Upload applications and not made for security applications. With a FTP Upload the camera will limited the Videoclip via FTP to max to 10 Sec Before and 10 sec After.
As shown in the Admin - FTP Profiles Dialog:
I assume you are not performing any Web Applications and it is more based on security reasons. In this case i would recommend to use the Recording of the camera on the internal SD Card or connect a local NAS as Fileserver to store the recordings.
In this case the Recordings will be as you have setup in the Setup → Recording dialog.
With the MOBOTIX Management Center VMS (MxMC) you can access to the live and the recordings and proceed playback and export of the recorded video.
Based on the configuration of your environment you can access the Camera and the Recordings as well from remote!
A quick overview of the MxMC important functions are shown here:
The Playback usage:
How to setup the MxMC and Camera for Fileserver Recording is described in this Manual at page 28!
The NAS (Fileserver) setup is depending on the NAS type, if you have a MOBOTIX NAS or a QNAP NAS , the pages before explain almost the important steps to setup your NAS.
