Saving to Network Storage (NFS)

[mtrovato]

Hi all,

I am using a Chronos 2.1-HD High Speed Camera. I followed instructions in https://www.krontech.ca/wp-content/uploads/2021/09/Network-Control-v0.6.5-1.pdf and, when connecting my computer with an ethernet cable, I have access to the camera via the assigned IP. However, I don?t know how to save the footage over the network via NFS protocol. In page 29-30 of the manual (https://www.krontech.ca/wp-content/uploads/2021/09/RE-PDEV-10009-Chronos-User-Manual-Full-Software-Version-0.7.0.pdf) it is stated that step-by-step instructions are given in https://www.krontech.ca , but I have failed to find them. Can you please help?

Also notice that I can successfully share files between two laptops via NFS

Thanks
Best,
Marco

I have absolutely no experience with Sharing Folders / Storage for this Camera or File Transfer over Network, but the closest thing i could find from a ~2 Minute Search on the Website is this:

I hope this helps, else somebody else Please Help.

There are also these Forum Posts / Threads, which one off is still on a pretty dated Firmware version, and both seem to use Some Linux OS, from flying over it very quickly. But maybe you can get some information out of there, or if not send a Personal Message to anyone in there, that got it to work aparently.

I have done exactly what is in the first link and I didn't suceed to establish the connection. I will try it again and, if not successful, send a PM to gcp5017, who seems to have succeeded.
I haven't tried SMB but that is definitely another option.
I will keep you posted.
Thanks

I have connected the camera and my desktop through a router and the NFS share works perfectly . Let me share what I have so others may benefit from this thread.

- Host: laptop with centos7

ifconfig [network] [192.168.0.XXX] netmask 255.255.255.0
followed server instructions in https://www.howtoforge.com/nfs-server-and-client-on-centos-7 . Among other things I have created shared dir /dir

- Client: Chronos Camera 2.1

Utils -> Network -> NFS Network Storage
Address: 192.168.0.XXX
Mount: /dir

Test and Apply

Thanks for your help
Best,
Marco

I've been unable to make this work, as the NFS server here requires authentication.  Is there any config in the Chronos to set that up?

 

[kadilakGAD]

normally in Linux you enter the authentication directly in address field for address in format: user[email protected]
I have never tested it on chronos, but it is worth of trying

Setup:
NFS Server: Windows Server 2025, Kerberos deactivated, anonymous and UID/GID access tested, acts as domain, dns and DHCP server

Chronos 1.4: Firmware 0.7.2, reachable by the server over ping

I want to set up a nfs share on my Windows 2025 Server. It uses nfs Version 4.1 and the connection is allowed for the IP of the camera.
My Windows PC can mount the share, but the chronos gives me an error mount.nfs: mount system call failed.

I looked through the firewall setup and found that for the inbound connection port 111 for UDP and TCP is missing so I added it.

Now the camera takes a really long time to check the connection and is not responsive, but ultimatly fails with mount.nfs:Connection timed out.
Windows Server says the adress is <servername>:/<sharename>, but i put into the chronos ip adress and under mount the share name.

The camera can connect to my QNAP NAS just fine.


Does anyone have an idea?

Try logging into your Chronos via SSH if you're comfortable with that. From there you could try querying the NFS shares your Windows server is exporting:

showmount -e {SERVER_IP}

The command the LCD interface triggers internally follows. You could try running it manually with verbose (-v) enabled for more info on what might be going wrong

mount -t nfs {SERVER_IP}:{SHARE} {MOUNT}

If you use the settings for configuring the NFS connection on the camera's LCD interface, it will make your Chronos routinely try to reconnect to the share, which as you've seen can cause the UI to hang, especially on initial camera startup.

Thanks for the fast answer!

This is my share on windows Server:

Choosing the "Anonymous" option will lead to me beeing able to mount it on a win11 machine but not able the write on it.

I tried mounting the share on the camera via ssh, but that didnt help either:

I created a directory on the camera to mount to:
mkdir /mnt/CAMshare

And then I tried to actually mount the nfs share:
mount -t nfs <serverip>:CAMshare /mnt/CAMshare -v
mount.nfs: timeout set for Wed Jul 1 08:47:23 2026
mount.nfs: trying text-based options 'vers=4,addr=<ServerIP>,clientaddr=>CamIP>'
mount.nfs: mount(2): Input/output error
mount.nfs: mount system call failed

The same share works on my Windows PC in the same domain via CLI:
mount -o anon \\<ServerIP>\CAMshare T:

I tried to setup a WSL NFS Server, but I wasnt lucky doing so. I can only connect to it from the same server via the VM-ip address.

Also where should I mount it in order to access it from the CAM GUI?

I deactivated the windows firewall and now am able to mount the nfs share via ssh if i use nfs version 3:
Port 2049 was free before so I do not understand why it helped.

root@chronos:~# mount -t nfs -o vers=3 <ServerIP>:CAMshare /mnt/CAMshare -v
mount.nfs: timeout set for Thu Jul 2 09:58:04 2026
mount.nfs: trying text-based options 'vers=3,addr=<ServerIP>'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying <ServerIP> prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying <ServerIP> prog 100005 vers 3 prot UDP port 2049

The only problem now is I cannont save onto it.

Hello! Did you have any luck with resolving this?

The SSH commands I suggested were mostly for troubleshooting. The Chronos 1.4 mounts NFS shares at /media/nfs. Once mounted successfully, it should become a saving destination option.

One sort of quirk which actually may be helpful in your case is mounting the share via the camera's web interface. Unlike the camera's LCD interface, the web interface forces NFS version 4.0, which you might have better luck in combination with Windows Server

Hey,

the connection is only possible with nfs version 3 put in the ssh command.
mount -t nfs -o vers=3 <ServerIP>:CAMshare /media/nfs -v

Version 4 does not work
mount -t nfs -o vers=4 <ServerIP>:CAMshare /media/nfs -v

mount.nfs: timeout set for Mon Jul 20 04:31:38 2026
mount.nfs: trying text-based options 'vers=4,addr=<ServerIP>,clientaddr=192.168.100.207'
mount.nfs: mount(2): Input/output error
mount.nfs: mount system call failed



I am then able to see the network location in the Camera and can also save to this share. The information will be lost after reboot obviously.

The camera will not save automatically onto the share when connected via SSH. Web interface does not work unfortnunately.
The webinterface says Version 0.7.0, the camera says 0.7.2
