I have to read up on how to upgrade an old 3750 switch. Could the issue be that it is a 10/100 (too slow for newer cameras?)

No, 10/100 should be fine, IP cam don't do gigabit anyway.

If you take off all the new dahua cam but leave the hik on the switch, then add only 1 dahua cam does that cam work? now take off dahua 1 and connect dahua 2 to the switch, does dahua 2 works? same for 3? now connect 2 cam at a time do both cam still work? all 3? I suspect you are exceeding the POE switch's power budget.

edit--

Also does this problem only occur at night? IR LED can increase power draw and push the switch over the edge.

On a 3750? that switch should be able to handle a lot of power no? I think it has about 400+ watts available. Currently the only poe devices on it are the 5 cameras (2 hikvision and 3 Amcrest).

Hard to do that test because it takes about a week before the camera crashes.

Ok that's' less likely but still possible, on a switch that old the Power Supply can be failing, but again not likely with only 5 cameras. When you mention 3750 i assume it would be quite alot of cameras, otherwise wouldn't need something that many ports

Are all the camera showing the same time stamp? I had a very werid crash issue before where a Dahua NVR push a time-sync to a Hik compatible PTZ via ONVIF would crash the camera due to daylight saving time issue.

try the auto-maintain function to have them auto self-reboot weekly or daily. shouldn't need to do it but if you are running out of options. Mine are all set to reboot weekly just to prevent problems

All cameras seem to be on same date/time stamp. I disabled the camera overlay so just using BI date/time. I checked to see what the camera's time was and it was slightly off. But I assume this is not the issue you are bringing up?

I set to restart the camera everyday at 4am. Just did it on my rear camera to see if it makes a difference.

no, it was off by an hour DST... the cam would NTP sync to the right time, then the NVR would sync and push the time an hour off and crash the camera somehow

Check the logs in the camera? They may tell you what happened, e.g. if it rebooted or what.

I can try rebooting them occasionally. But again, this is not practical and should not have to be done...
I now have all my Amcrest cameras set to reboot nightly. The symptom has gone away. Not the ideal way to work around the problem, but it does work around the problem.

Yes. I also set them to reboot. I think I set it to once a week. Since they all seem fine. I agree, not ideal but it works.
