Adding a NetHDD for Hikvision Cameras

[ARAMP1]

I've read some older posts about there being a cap on the size of hard drive that can be added and I've read some other posts with people having multiTB drives.

I have a Hikvision LPR and I have a 200Gb micro SD card in it. With as much traffic that goes by, it only holds info for a couple days, so I decided to add a HDD storage location. I first started with an 8TB drive and the camera wouldn't recognize it. It was able to add the NAS location, but it came up as 0GB. So, I took that out and put in a 1TB drive.



The status will stay normal and then go to Uninitiated after a few minutes.



Is there a size limit and if so, is there a way around it?

Without knowing more (model number, firmware revision etc.) its impossible to say.

I have a 16TB drive at the moment carved up into 1 and 2TB segments which I have mounted on my cameras without issue.

Awesome. What camera is that? And what NAS are you using?

Here's my camera info. I've tried connecting it via SMB and NFS and get the same results.

My NAS is a CentOS 8.2 machine running on an Intel NUC with a 16TB SATA drive attached.

Thanks. I actually have a bunch of those cameras (though I'm still on V5.6.3). I might try it with those and see if it works.

Its been working for me for a long, long time. Even with my 4MP cameras which I've had for several years.

If it doesn't work for you, then I would suspect your NAS.

A stock Linux system works best IMO rather than vendor-specific solutions.

Cool. I was using FreeNAS on an old J1900 machine that I was running pfSense. Interesting that you used SMB vs NFS with Linux.

The way I explored this a while back was by changing the volume size and seeing what happened, both for NFS and SMB/CIFS.
Where the server could apply a user quota on an SMB/CIFS share that worked OK.
But it's a bit of a grey area, the results for which vary with the camera firmware version.

Years ago I had problems getting nfs to work. There's probably still some of my old posts in the NFS/SMB thread. Probably had to do w/ quotas etc.

What I ended up doing, as illustrated above, was using fallocate to create a disk image file which I mounted via the loop interface and then exported. This way the disk looks to be the exact size its allocated as.

May work with NFS as well, I didn't go back to try.

Alastair is right though, its hit or miss, although I think the newer versions of the kernels pretty much support 2TB volumes. Larger than that, maybe not., I haven't tried on my own system.

For ShitsNGiggles I opted to carve out 3.5TB of drive space for my camera... Accepted it w/o an problem and seems to be recording events just fine.
