No, 10/100 should be fine, IP cam don't do gigabit anyway.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?)
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
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 somehowAll 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.
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.I can try rebooting them occasionally. But again, this is not practical and should not have to be done...
