Bapples -
Thank GOD. I thought I was going mad.
I'm also having this issue. Every 10 seconds (according to the first two digits in the file). I even turned off motion sensing all the way down, and then off completely, and set my "general" scheduled to be 1 minute after midnight to 2 minutes after midnight. Nothing fixed it.
I actually found your post by searching for "Record Control" thinking that may have something to do with it. Setting it to manual does nothing. Setting it to OFF does NOT stop the FTP for me. So that is different?
I don't have my email setup to email me triggers. I also don't have general or alarm enabled on the storage for FTP, only Motion - and only for snapshots. It's like no matter what I do, if I have FTP enabled - it shoots me a new image with a time stamp of every 10 seconds from the last boot.
It's not just your camera model. I have an IPM-723 bullet, and it does the same freakin' thing. It's been driving me crazy due to how quickly it's filling up my FTP drive. I don't want continuous recording, only motion!
This isn't something new either - I tried to get this working over the summer and had the same issue. Back then though, my FTP server has a TB drive - and I setup cron jobs to remove the files after a few months time, but now that drive is dead

and I'm using a much smaller drive for storage. I have been trying to figure this out, but I don't think it's anything we're doing wrong. It's got to be software. I did recently upgrade the firmware over the summer. I may try to kick it back to the earlier version to see if that resolves the issue?

I really don't want to record to an SD card either. I want to throw those images up onto my FTP so that I can rclone them over to my google drive for safe keeping. It's crazy that you only posted this a few days ago! Please keep me posted?! I'm planning on calling them tomorrow night if the refresh to the earlier build doesn't work.
