I have an Amcrest IP4M-1041W Camera that I cannot get to update via NTP. I've checked using Wireshark and there are no NTP packets coming from the camera.
Is this a known issue or maybe I'm doing something incorrectly.
Try a different NTP server.. Maybe they are having issues right now. Over used or out of service I use my own NTP server so don't know.. Is the Zone set correctly.
