    Hi Luke,

    No worries. That is where our community portal is for; asking questions. 

    For the RPI3 there is only server software available for. You could record up to 12 HD resolution cameras on these. 

    For the client we have an experimental 64 Bit ARM version available, but A) it's experimental and B) it would apply to a Jetson NANO board, which is quite costly and an Intel NUC or similar is likely a better option. 

    These would cost you approx $ 180-$200 with a J3455 Quad-Core Celeron processor and at least 4 GB RAM and a small SSD (64-120 GB) and this is just fine for running only the client with up to 16 cameras in a layout. Also, I would recommend running Ubuntu on it, since it saves you some resources opposed to Windows 10, and it would save you the cost for the license of the OS as well.

    Thanks for the helpful info. Sorry I was confused there.

    Are there any plans for supporting the RPi 4?

    I unfortunately can not get NUCs of those specs where I am at. I’m working with an anti-trafficking NGO in SE Asia. I had hoped the RPi would work since they are so affordable. Jumping from $50ish to importing $200ish + taxes isn’t a huge jump, but for NGO budget it is significant and we’d need to adjust and plan for where and how we’d set things up. Just sharing the feedback for where we are at :)

    I might be able to find some Chinese NUC copies, but would probably be better to find a way to get what would be more reliable. We use some i5/8G Dell 3060’s that we’re around $500. But dropping down to an older model at i3/4G might be my best option, but I’d guess $300.

    Thanks again for the info!

    Hi Luke,

    There are plans for the RPI4, but not yet very high on the priority since it requires a lot of efforts due to the different architecture and also the heat production of the device and the constant load of a VMS on the device causes a risk in reliability. 

    Regarding the price of an RPI, please for not forget accessories like PSU, SD card, and a decent case. In europe that would cost you approx. $ 85,00 in total. 

    The Chinese NUC, often aren't much more affordable than the original Intel NUC, but it might be worthwhile to look at.
    Another consideration could be to look for refurbished equipment. Often Enterprises exchange hardware after a few years and you can buy the 'old' equipment for less than the price of the RPI with the accessories.

    Looks like someone replied but that is gone now? It mentioned an experimental version of the NX Client for 64bit ARM, but that it was untested on RPI4. I’d be happy to participate in beta testing this. I’ll have an RPI4 on Tuesday and could experiment.

    Hi Luke,

    I noticed it as well and removed it since the information provided was incorrect.

    As mentioned before, there is an experimental 64 bit arm build available, but at this moment Nx Witness isn't supported for the RPI4.

    You can download the experimental 64 bit ARM client via the following link:

    I may give it a try.  I did notice that Intel has a new “ruggedized” NUC coming out.  Chaco Canyon (NUC8CCHKR).  It’s fanless, so it would work great in a dusty guard shack, but it only has a 2 core, N3350, vs the 4 core J3455 you had mentioned.  

    You think it would be able to handle it?

    I haven't used it myself, but other people had better experiences with the quad-core than with that dual-core models. 

    The Nuc with the J3455 is also fanless.
