New AI cameras randomly stop recording

[Revo2Maxx]

Sorry don't know. That is really odd for sure. I wonder if maybe the format was after the updated FW and maybe it is written with different format type of the MSD. Maybe if easy access take the MSD from other camera, Format, it first, then swap them and as soon as you put it in the new FW camera Format again for the camera. Then with old card from the one you installed new FW into have it in the other camera and format and see if there is anything like it was before...

I would setup a Ticket with Amcrest, If they are not aware of an issue they might be able to get a new FW to correct the issue. I am not sure how long it would take in time for such a FW update I am still waiting for one for a camera issue on my 7108 DVR where a 5mp Amcrest Camera don't want to show as 5mp or use Audio. That has been 3+ months now.

So I moved one of my 128gb WD Purple Micro SD cards to my camera and I changed the info to be stored on the MSD and not the FTP as I had it before. When I moved the card from a 4mp AI IP camera to the 8MP AI camera at first it showed an error as you can see in the picture below, I then formatted the MSD and everything says it is working and the camera Reboot. Only 2 things shows System on my Logs. The rest says admin. So I am guessing there might be an issue with your camera still. You did a factory Reset after doing the FW update?

I updated and factory reset one of the cameras, then reformatted the SD. Verified the new firmware build but saw no change.

Then as quick as it started, it stopped, on all the cameras. As if there were never a problem.
I backtracked and found similar gaps on other cameras I administer in a different city. Older models.
Its got to be some sort of zero-day bug that affects them the same way DST changes screws with them.

Yeah I personally don't know. I even to this day have some cameras that oddly have some issues when it comes to putting the footage down to the Micros SD cards. Even though I am using the WD Purple cards. I will go look at some history of the camera and when it shows there are some days that don't have anything even marked like the camera was offline that day. However the good news for me anyway is that I have them also recording to a NVR so if there was footage it should be at one place or another for the day.. I don't know maybe some of my AI cameras if there is no footage just don't show any use that day. Maybe it is something by design. Important feeds I have on my NVR's recording full time in Sub channel format. I mainly use that for audio so I don't miss something that might have happened before the person hits the Rules that are set, or after the rules record time has expired.

One of the issues with AI cameras is that if you have a Wide rule setup and the person enters that area it will only record for a short time unless you were to have motion setup as well. I personally don't have motion setup to keep the false triggers down. However in one of my AI cameras I have an Intrusion setup and a tripwire that will trigger a different audio alarm. Only down side if the lack of being able to turn them off within the app. This way I could go to the area without the alarm going off and or to be able to mow the lawn without having to hear the alarm every time I pass one of the rule zones..

I would keep an eye on your cameras for a little bit and see if things work out of if the issues return. Hope they are gone for you for good. Nothing worse then having to worry about capturing something that was needed.

After buying 3 new analog cameras this year( a 5mp and 2, 8mp) I have been toying with the idea of pulling my Analog DVR's from service all together. There are some things that I like about them over the NVR's and IP cameras. I just haven't used them as much as I do the NVR's these days.

FWIW of all the Amcrest cameras I have operational at every location, these two were the only ones that *did not* malfunction after Daylight Saving Time in the US ended on November 5. Apparently the older firmware could not cope with DST and caused the cameras to loose programming and randomly start and stop recording.

CORRECTION -- The DST bug is still in the firmware for the new AI cameras; it just took a couple of days for it to show up.
The camera just stops recording. It will resume briefly after a login but quit, and may briefly resume after some other sofar unidentified trigger.
A reboot or two seems to resolve the problem until the next time change.

Its not a LAN issue or a problem with a router because its an identical glitch affecting cameras hundreds of miles apart at the same time.

Yes, the US needs to get rid of Daylight Saving Time (if for no other reason than its adverse health effects), but until then, I cant help but wonder if this bug isnt just one symptom of a bigger problem lurking in the firmware.
