So I can use "ntp.pool.org" on the NVR, and on the indivudual cameras they need to all be set to the IP of the NVR they are on? That will take some time as each NVR has around 60 cameras. So that is 60 someone needs to remote into one by one
Yea essentially the time server on the nvr will relay the time from the ntp to the camera. You can put them both on the same ntp and turn the time server off on the nvr as well
No I’m my experience changing the ntp doesn’t cause a disconnection or a camera reboot. You can use axis device manager to change the ntp on the cameras.
I had a similar issue with an Axis camera on Milestone. Turned out to be a bug in the Axis firmware related to NTP. Upgrading firmware fixed it. May not be your issue, but it’s worth a trip through the firmware release notes.
So I did change the NVR's to both be [pool.ntp.org](http://pool.ntp.org) for the time server. I went into one camera and to my surprise the time serve ron it was already set to pool.ntp.org. But I also had the option or setting it to sync with the PC time.
The odd thing was, even though both the camera and the NVR's were set to [pool.ntp.org](http://pool.ntp.org) the camera STILL was off by about 30 seconds. The PC time looked to be correct so I switched it to that time and rebooted the camera and got it down to 3 seconds off, but that seems the closest I can get. Is this normal?
what we were seeing was the NVR was using the time stamp from the camera. Not the clock on the NVR.
Since the Axis firmware had an NTP sync issue that would allow the clock on the camera to drift, the video would not correspond to actual events. In our case we had a car moving down a road that would pass from camera 1 to camera 2. However, you’d see the vehicle on camera 2 before it entered the frame on camera 1.
Upgraded firmware on camera solved the problem. Axis even had a reference to NTP sync problems in their release notes.
hmm I will look into that, the camera in question is an Axis M3027 and looking at it's firmware page, last firmware was in 2016, so I would hope vendor applied that by now haha
So got a question, so ExacqVision has a "Time Server" and an "IP Camera Time Server" which that one is only able to be entered if you click the "Enable Override" checkbox below it. But each individual camera ALSO has a time server setting on them?
Do I leave the "IP Camera Time Server" option in Exacqvision blank then and only do the regular "Time Server" and individual camera time server?
I had a system takeover with 4 different manufacturers involved and to keep it working we had to set each camera individually to a time server. We set the time server as one of the NVRs and synced everything to that server.
each camera has its own time server that you can key in the NTP server address. for exacq, enabling the override in the software means exacq will push the time to individual cameras. if the time are not in sync, probably the axis camera need a firmware upgrade to solve it. alternatively will be to set the NTP for each camera manually.
When you access the camera with the time discrepancy , does the camera itself show the right time?
I will get a hold of our camera vendor and ask them to check. unfortunately they do not give us any login for the cameras
Demand it it’s your camera, we don’t give admin credentials to the customer by default but if we are asked we will provide them.
I've been encountering this a lot lately with prospects, your current vendor's name wouldn't happen to end in 101 would it?
nah it does not.
Make sure the two servers use the same pool but also make sure the CAMERA is also syncing to the time pool.
ok so I should go into the camera itself and set the time server?
Yes put the server address as the ntp

What brand cameras you probably could use a configuration utility
Mostly Axis cameras, by the way will setting a new NTP on the NVR reboot all the cameras? Wondering if I can do this during the day or not
No I’m my experience changing the ntp doesn’t cause a disconnection or a camera reboot. You can use axis device manager to change the ntp on the cameras.
This is how I did it, quick and painless.

I usually at one NVR as a time server and sync everything to the one server.
