Hello,

It is peculiar as to why FTP Postpone exists and it's need is still not explained properly in any available resources.

I lose the first 5 seconds of recording using FTP from when the camera senses a movement to the start of the recorded file. I assume this is from a delay in turning on/setting up a recording before the camera starts to send it over FTP, but the lack of "Pre-Motion Record" in the FTP menu is also peculiar.

"Pre-Motion Record" is included in the Record menu (ie SD card recording) and seems to be a fixed setting providing around 8 seconds of pre-recorded footage. Also the SD card does not appear to supplement the FTP footage and they act as separate parallel entities.

Just to provide some info about my set up + eliminate some possibilities, I have done some testing:

• Tested on camera firmware: v3.0.0.1337_22091901 & v3.0.0.1889_23031701
• Duo 2 Wifi hardware version: IPC_529B17B8MP
• Client version: 8.8.5
• I am using a 1Gb ethernet.
• Camera is on a 1m ethernet cable and computer is on a 2m ethernet cable.
• SD card is Class 10 / U3 / V30.
• Windows 10 firewall On or Off makes no difference to the delay in recording.
• FTP Postpone has a "5Second(s)" minimum setting when accessing the camera through the browser as opposed to the "15Second(s)" in the client software - Still makes no difference.
• Clear or Fluent streams do not make a difference.
• "Transport Mode" does not make a difference.
• FTP or FTPS does not make a difference.
• Turning off "Pre-Motion Record" still provides around 3 seconds of pre-recording but only for the SD card.

I am guessing that since the "Pre-Motion Record" option is available for the SD card then it would not be too much trouble to implement for the FTP recordings. Even if the SD card was required to be installed to supplement the pre-recording for the FTP footage it would still be of benefit.

Just after my original message I ran into a problem with my FTP recordings. The files were being created but not completed, ie they were unplayable files of 0KB size.

After a few moments of trial and error, I set my FTP Postpone to "15Seconds" so there was no longer a mismatch between the browser setting and client setting (as per bullet point 8). I also rebooted the camera after changing the setting and the FTP recordings began to work again.

I then decided to test the Clear / Fluent settings again just to double check my findings above and now I get zero delay on FTP recordings when the stream (or should I say Video > Resolution setting) is set to "Fluent". I am not sure what has changed other than a firmware upgrade + a user-triggered reboot (rather than the automated reboot as part of the upgrade process).

Just to note, the latest firmware (v3.0.0.1889_23031701) is not automatically retrieved by the camera. I had to download it from the website.

I am not sure if the above helps anyone but it would be nice to have zero delay on the "Clear" setting for the highest resolution.

Interesting... Useful software too, thanks for the link.
