I noticed this morning, that all my 3 IP2M-841B-V3 stopped recording at the beginning of March within a period of about one week.
They all upload pictures and videos via ftp to my NAS. That used to work reliably for years.

I gave each cam a reboot and meanwhile each cam has created a folder with the current date and saved there pictures and clips.
The old and expired folders (I keep them 14 days) were deleted as expected. So in short, they work again.

Anyone with an idea what might has happened?

I should mention that I installed new firmware (Amcrest_IPC-Consumer-Web-Mao-Molec_Eng_N_AMCREST_V2.800.1ENN001.0.R.241029.bin) on these cams about 4 weeks earlier, so that is slightly suspicious and a possible cause.

But then I would expect others to report similar experience here...
 
Mine are still working, but I prescribe to the "don't fix what ain't broke" mantra and haven't updated the camera since it is working for my needs.

Other than some wonky thing with the firmware, if it happened beginning of March, could it be some time issue with NTP and a discrepancy between the camera time and the NAS time is causing some issue?
 
Thank you for your ideas. DST time change is on the last Sunday in March here, so next sunday.

I checked the time anyway and the cams and the NAS are running the same time.
