So what is the secret with the NPT on Hikvision cameras

If your cameras are connected to the PoE of the NVR, Check your cameras GW (gateway) to make sure it is the NVR's internal IP.
EG:
Camera 192.168.254.100
NVR Internal 192.168.254.1
NVR GW = router address
Can you ping your cameras from your network?

That generally works OK, especially when the cameras are on the LAN, as opposed to NVR PoE ports, which needs a networking config to help it.
But it does seem to be the case that Hikvision devices prefer to use something like Google's 8.8.8.8 DNS as opposed to the DNS relay on the LAN router/gateway.
Try also time.windows.com and see if that tests OK.

Connected thru a Cisco GB Switch and a Cisco GB Router just like the rest of the devices. (security system, Thermostat etc...)
I have a NVR also hooked up to the same Switch and it syncs its NPT time every 3 hours.
Thanks for the responses

I know this isn't exactly what you asked for, but generally you are better off not allowing the cameras and NVR to have internet access at all. That way they can't be hacked, and if they're already part of a botnet, they can't do anything without internet access. If you have an always-on PC on the LAN, you can run a time server on it and sync to it by IPv4 address as often as you want. I prefer to run mine on a Windows box with NetTime from here: NetTime - Network Time Synchronization Tool

The Cisco router is managing internet traffic. Never had any alerts since system was setup.
This is VERY strange as all my other cameras use NTP = time.nist.gov port = 123. I just tested it on an extra camera I have and it worked perfectly.
Tried updating the firmware. no glory.

Make sure your cameras are using the right DNSs.
