IPcam: Nx Witness full install demo on cheap/low-power NVR hardware

This article is an accompanying article for my video about installing Nx Witness on low-power and cheap hardware, go check it out!

Video part

As mentioned, this post is an accompanying post to a video, check that out first:



Shopping links

Sadly the MelePC isn’t for sale anymore, a good successor to this box (Actually has an upgraded CPU!) is the Chuwi Gemini Lake box: https://geni.us/38TzGV

Power meter used: https://geni.us/h8kokVq

Internal 1TB 2.5″ HDD: https://geni.us/9TP4W36
Internal 2TB 2.5″ HDD: https://geni.us/BacR

If you need (a lot) more storage, using an external USB3 disk is the cheapest option like these 4TB variants: https://geni.us/WEAsX9

In this video I’m installing the 4.0 Beta of Nx Witness on Ubuntu 18.04. This is a beta version and not suitable for production systems! If you want to run Nx Witness in production and not just for test use the (also excellent) 3.2 version on Ubuntu 16.04 until the final 4.0 is released!

Download Ubuntu and create USB stick

During the video I do an operating system install of Ubuntu 18.04 LTS. You can download the Netinstall ISO file here.

Once there you want to select the version and then download the “mini.iso” file. This is the file we are going to use with Rufus to flash to our USB stick.

The Rufus tool can be found here: https://rufus.ie/

Once you have all that, create the USB stick and you can continue!

Ubuntu OS install

*For my MelePC machine I change a BIOS setting to make it more Linux compatible!

During the OS install I accept most default options, the only things I change are the download server location (I’m in The Netherlands) and I select to install the “OpenSSH Server” package during the install so we can remotely connect to the machine with SSH later on.

Installing Ubuntu to the onboard 32GB E-MMC memory works great!

Installing extra packages

After the install completes I like to install the following packages using this command:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install dstat htop nano gdisk wget

Adding internal disk

cd /dev/disk/by-id
ls -l
p (show partitions)
d (delete partitions)

(all partitions deleted, clear disk)

n (new partition)
w (write)


sudo mkdir /mnt/internal1tb

sudo nano /etc/fstab
/dev/sda1  /mnt/internal1tb  ext4  defaults  0  0

After these commands the disk should show up during the “df -h” and is available for use!

Nx Witness CLI install

Follow the video and download the Nx Witness Ubuntu server binaries from https://www.networkoptix.com/

While you need to download the Windows Client (or Mac/Linux) for the Ubuntu server binary it’s easiest to copy the URL so we can download it directly on the server machine using wget like so:


After downloading we are ready to install it

sudo dpkg -i nxwitnes.........................deb

This install will probably fail because of some missing packages, to fix this run

sudo apt-get install -f

This should fix the missing packages and the install should automatically continue!

Nx Witness GUI install

After all CLI stuff is done you can use the GUI on your machine to continue the install process.

And that is where this part of this text post ends, continue with the video for all the GUI parts!

Nx Witness NFS storage

To link an NFS share you need to install the NFS client package

sudo apt-get install nfs-common

Once you have that and you have an NFS share available on your NAS you need to create a directory to mount it

sudo mkdir /mnt/nasovernfs

Once that works we can do a test mount of the NFS share to that directory

sudo mount host.local:/nfsshare/directory /mnt/nasovernfs

Once that works we can add it to our fstab file again to make sure it reconnects during boot

sudo nano /etc/fstab
host.local:/nfsshare/directory /mnt/nasovernfs  nfs  auto  0  0

You can exit nano with [ctrl-x] again and make sure to save the changes and reboot the machine.

Once done, Nx Witness should automatically see the extra storage in the GUI!

All done!

  1. Hi, the CHUWI GBox Mini PC you linked is around $390 AU through bangood. Have you heard or had experience with using the ‘nvidia jetson nano’ running nx witness 24/7 as an alternative to the CHUWI? Pricing for a nano is around $200 + a case.

    How is the new NX Witness v4 running now? Perhaps an update video regarding the differences from v3 to v4?

    Thanks for your time and your videos!

    Nic. From Australia.

    1. The Jetson is really only interesting if you are using the GPU which an NVR will not. CPU wise the Intel is a few times as powerful so they don’t really compare.

      v4 has been running well for me! I might make an update video in the future. 🙂

  2. Hi, Your link for the Chuwi Gbox is not coming up on aliexpress. Also sold out on amazon and bangood. I did track an item, bit checking it;s the right one. Its CHUWI GBox Pro Intel Atom X7-E3950 Quad Core Windows 10 OS 4GB RAM 64GB ROM Gigabit Ethernet Mini PC 2.4G/5G Dual Band Wifi

    Only has 4gB of ram, whereas you originally used 32Gb. Is that the right model?

  3. Quindor–Great video! Thank you for created it.

    You mention a forthcoming video on how to offload some of the processing work to the ip cameras as well as how to get Nx Witness to work with a NAS device. I haven’t been able to find these on your YouTube site. Where can I find them?

  4. Thanks for all your hard work reviewing especially Dahua cameras and NX Witness. Based on your work I have bought and installed quite a few Dahua Cams. NX Witness is also very nice -servers running on Raspberry Pi 400, Odroid M1 and lately Intel Nuc i5. My problem is finding people who will sell me as an end user the camera licences. Are you able to suggest which of the online stores in Nederland would be able to sell licences into New Zealand? Much appreciated.
